content: I am in the market for a new 4K monitor. My aging Acer Predator X34A has at 5 years old, delamination artifacts and I plugged an HMDI lead into the Display Port and now I have no display port inputI already use mini eWaste PCs for media centers on 4K TVs in the livingroom and bedroom. Honestly, even sitting right up close a 4K desktop looks absolutely fine to me on the modern 4K TV.I know a TV panel will not impress the avid gamer but I have modest requirements, as long as it does 60Hz at 4K and doesn't suffer from ghosting or smudging of text, it sounds grand to me.A 43" 'proper' monitor panel will cost you £1000. Yet a 43" TV panel sold as a monitor costs £450. I'm thinking a TV sold as a TV might be even cheaper.It seems the manufacturers are on to this as literally in the past few months more and more "TV panel 43"+" monitors have appears from Phillips and Samsung. The give away is the almost complete lack of Display port inputs. Which is a bit of big deal for me as my mini PC only does 4K on DP.The only issue I have heard of and seen with a TV panel is "burn through", or persistence around areas of high contrast which can linger for a few minutes. That said however, my £1100 Acer Predator X34 will do this as well if you leave it with black and white boxes long enough.Any thoughts opinions? Any deals spotted available to UK? Best bets? Is "Good used" on Amazon worth a punt to save £50?

content: IMO 43" is too big for a PC monitor which for best eye strain should be no further than 4 foot from your keyboard. 32" is about the maximum you want to go.I have 2 x 28" monitors on a cantilevered arm - Samsung U28E590D. When I got them they were £199 each, but it looks like the price has risen so you may want to wait for a deal. More than bright enough, 3 inputs, 60Hz available on two of those including HDMI. Only complaint is the auto detect input doesn't work that well so switching between work laptop and home desktop PC means fiddling with the control on the back - little joystick thingy.More than bright enough even at 20% setting and I do occasionally play games on them - to my eyes no appreciably bad motion blur.Note HDMI and DP are passive adapter capable, so my desktop PC has DP on it but is connected to the monitor using £8 DP to HDMI cables - works absolutely fine. I believe the DisplayPort will switch into a HDMI backwards compatible mode so this should work with all HDMI monitors. Be sure any HDMI port you use is 60Hz capable - 30Hz isdreadfulfor a PC monitor.

content: Quote from: paulca on April 19, 2023, 01:09:47 pmA panel delaminating after 5 years is really bad. Having worked with some TV makers in Asia, they all seem to target a level of reliability that would support them offering at least 6 years warranty and >8 year product life.I use 43" LG TVs as my computer monitors. Gamers don't like them that much, but for the rest of us the panels are superior to the high end monitor ones, offering better image quality in exchange for a little less responsiveness. You have to hunt around the menus in most TVs to find the trick that puts them in 4:4:4 mode, with all the temporal filtering turned off, but I've yet to find a TV where you can't. The right settings are rarely documented properly, and some TVs love to keep changing those settings until you find the right trick to make them permanent. If you want a single monitor a TV is no problem. If you want multiple monitors you have a big restriction with graphics cards. TVs have no display port input, and few GPU cards have multiple HDMI ports. I use a GTX1050Ti with 3 HDMI ports, and three 4k TVs. I am very happy with the results I get. 40" TVs would be better. 43" is just getting a little too big, but 40" panels are rare these days.

content: Quote from: tom66 on April 19, 2023, 01:32:25 pmDP has multiple streams, and spreads the bits across them at high resolution. HDMI does not. This was how DP gave us 4k 60fps before HDMI 2.0 increased the stream rates. HDMI<->DP is only a passive cable for lower resolutions. At high resolutions you need to carefully check what is going on, and the age of the equipment matters a lot.

content: Quote from: tom66 on April 19, 2023, 01:32:25 pmMy current setup is 2 x 34" ultra wide. My screen area is 5ft across. I like my real estate. Not all of it is "prime" of course. And most applications do look ridiculous full screen.I have a deep executive desk, the monitors up on arms about 6"s of the desk. Right now, slouched back I can barely reach the keyboard let alone the monitor which is a good arms length and then a foot away. I run 125% scaling and sometimes even a +20% zoom in the browser, if I'm slouching. It does look ridiculous when you sit back up straight though. Similar on the living room TV I sit 3 meters from the TV and so I run 150% scaling and even more zoom.The Acer has to go, it's done, on it's last legs and based on obsolescence it's likely it will degrade even faster as it ages. The Samsung 34" ultrawide beside it is much younger, still has working DP portsand I'm happy enough with it.I've done the ultrawide thing, want to go back to having more vertical space and a normal aspect ratio.On DP/HDMI. From the brief testing and researching I did with this particular box and chip it seems....Windows 10 "Generic display adapter" driver from fresh install gives you 3440x1440 @ 29.6xHz over the DP->Passive->HDMI2.0 port. Installing the Intel drivers for the Intel Graphics 530 (APU) and that option goes away. The intel driver does not offer that resolution. Rolling the driver back and the resolution worked again... however instabilities were discovered and applications failing to render overlay panels etc. It seems as though the DP++ ports are aware of the passive adapter and the Intel chipset driver is reverting itself to HDMI compat mode and removing the higher resolutions. When plugged into a DP port with a DP lead (on the Samsung) it works fine in 1440 ultrawide @60Hz with the Intel drivers.30Hz ... I have lived with 30Hz for a few months previously. You get used to it. Unfortunately if you spend any time at all on a 60Hz+ display you immediately notice coming back to sticky treacle land.

content: Quote from: coppice on April 19, 2023, 01:36:15 pmAgreed. My <1 year old baller gaming PC doesn't care if it's HDMI2.0 or DP it does 1440P UW at 100Hz. It doesn't like HMDI1.x ports though, back to 1080P or 30Hz.EDIT: Thing is, it's summer. The heating is off. The 90-100W of waste heat from the baller gaming machine is no longer required or welcome when I'm not gaming. So I purchased yet more eWaste in an HP Prodesk (circa 2017 vintage). 90-100W?? More like 3-15W.Also... given the temperature of the back of the Acer and the Samsung (4 years apart in age), there have been efficiency improvements there. The Acer has a 150W brick. The Samsung a 100W one.

content: Quote from: coppice on April 19, 2023, 01:36:15 pm4K@60Hz works absolutely fine over HDMI<->DP passive cables in my case. I've so far not found a HDMI monitor that doesn't work with a DP adapter cable, but I accept that it's a possiblity that some older monitors may not like it. And it is possible that some older graphics cards or other peripherals do not support HDMI mode.Note that both DP and HDMI have four differential pairs in the cable, but HDMI dedicates one as a clock and data is on the remaining three, with TMDS signalling used to minimise EMC, whereas DP uses embedded clock with clock recovery at the receiver end (128b/132b in latest spec). So DP can transmit a lot more data at a lower effective bit rate, but is more expensive to implement due to the need to implement link training with clock recovery at the receiver end. (I've noticed my monitors flicker slightly on start up and show a few sparkly pixels for a few seconds before both monitor and GFX card seem to agree on what kind of sync is needed.)Quote from: wraper on April 19, 2023, 01:43:59 pmI must have missed this memo because my monitors are running at 4K@60Hz without any chroma subsampling using a passive cable. OK, maybe there is a small IC in them, but they are still not featuring much electronics in them to convert a signal so are something you can get pretty cheap if you need them.

content: Quote from: tom66 on April 19, 2023, 01:32:25 pmIn my opinion a monitor cannot be "too big". There is nothing preventing you from running your applications the same size as on a smaller monitor. You just get a lot of extra space where you can put multiple windows. I wouldn't mind having a monitor as large as a wall.I have a 34" ultra wide and I would never go back to a smaller monitor. I want a larger one. In the past I had multiple smaller monitors side by side, but one large is so much better.But watch out with the TVs. They have to have a port that accepts PC in without overscanning (or whatever they call it). On a Samsung TV that I have with multiple HDMI ports, only the one that says PC doesn't distort the picture with overscanning and possibly other filters. I would also check online before buying that people have tested it as a computer monitor. If you can't turn off filters and stuff, it could become annoying and even stressful to the eyes.

I watched people bug fixing the internal code of a 75" smart TV, using one of the TVs as their development terminal, in a cramped corner of the factory, sitting right in front it. That screen definitely looked too big.

I'm not intimately familiar with how it does it, though. Maybe the Samsung monitor is just treating the HDMI input as a DisplayPort? Worked on my Nvidia 1060 card and now the AMD RX 580 I have in my PC though.

content: Quote from: tom66 on April 19, 2023, 03:57:24 pmIts really annoying that most TVs and monitors won't display the kind of input they are working with. Many even make it hard to find the resolution and frame rate, but further information, like 4:4:4, are rarely available at all.The place sub-sampling shows up most clearly is with small coloured text. Is red text on a dark background really a nice clean red, even when viewed really closely?

content: Incidentally I purchased a 50" 4K TV for my computer a couple of weeks agoIt cost me 379 Euro (LG).I was considering this move for years and now that I have it, I can say that it is amazing. It is the equivalent of four stacked 24" Full HD monitors without borders. Finally I have desktop space for all apps running in parallel.I have a second full HD monitor attached just dedicated for Outlook.The screen is not to big. I sit about 1m away and with 53 years I have to take my glasses off to see short distance. That makes using a laptop with second screen a pain. The laptop is too close and the second screen too far. With this setup, I can use glasses always.Resizing screens was a worry but it is not an issue at all. You won't want to run most windows maximised, though. But for word and Excel full screen can be amazing.I have my also new workstation connected to it and this really kicks ass.I don't mind more tha. 60hz refresh rates. This is pretty ok and so is HDR.You do need to configure the screen though, as out of the box it will render the pc image very poorly.RegardsVitor

content: Quote from: coppice on April 19, 2023, 04:09:05 pmGonna have to munch on my humble pie here, at least on my RX 580 it is 4:2:0. I swear I'd tested this before - perhaps it was 4:4:4 on my old GTX 1060 or I was fooling myself somehow. That said, I genuinely cannot see the difference on ordinary desktop content - perhaps there are some use cases where 4:4:4 is critical, but it's already the case for me at least that 4K luma is beyond my eye's apparent visual sensitivity (in other words, I cannot distinguish the individual pixels in a checkerboard pattern unless I'm closer than 2 foot to the display).

Trying to edit with an editor that uses coloured highlighting is terrible with anything but 4:4:4. Most other things are just fine. There is a reason why we use colour sub-sampling. It plays to the strengths and weaknesses of our eyes, and works great most of the time.

What a quality crap, never seen this, ever!A 43" monitor will be like looking at a giant poster from 10".I bought a HDR 165Hz QHD 27" Lenovo g27q-20 in 2020 ($299), definitely getting into the "too large" area, I often struggle to find the mouse cursor, but the higher DPI is great, specially when splitting windows, but yeah, just at the limit of the visual field.My advice is to get QHD under 32", 4K will be too much DPI, and Windows scaling is crap, avoid using it at all costs.I know because I installed a FHD panel into my ex laptop, when she was doing the engineering 10yr ago, 1366x768 was a no-no for CAD and 3D design.Things were extremely small, 7pt text, but no problem, let's enable 125 (Or 150%) scaling!Now everything looked like I had breathed all over the screen!Now this this is the 27:

content: QuoteAbsolutely wrongI tried a 32" and despite having Windows scale at 115% (or whatever they do) it was still hard to read. And you lose pixels in the scaling. I gave it to my missus, mainly because nothing bigger would fit under the shelf where she has her monitor. My 43" is the same pixel pitch as my old 1900x1600 Dell monitors, so I can conceivably extend the screen without the cursor jumping around as it transitions. But my main delight is that I can read the bloody text without any scaling. Every pixel is a useful one.I sit just over an arm's length away - just measured at 32". It is fine and far more immersive than a tiny 32" screen would be for, er, immersive games and stuff.

content: Quote from: coppice on April 19, 2023, 05:56:53 pmIt also depends on resolution and screen size. On text on 2560x1440 27-32 inchers it's very noticeable, on 28" 4k, not so much. On video it video it will be very hard to notice except something high contrast like text is displayed. Chroma subsampling works in part because human eye has lower color resolution than brightness resolution, not to say brain hides imperfections and often sees what it wants to see, rather than actual image.

As noted elsewhere, the RGB stuff needs to be right, which many TVs aren't, and TVs are just designed for TV usage. Small things, like how blanking works (or not), can get right up your nose after a bit.I wound up with an Iiyama ProLite which has been a joy - not perfect but nothing is big enough to grab my attention. Got it cheap off Box since it was going obsolete, so great value as well. When this one dies, my next will be a similar pukka monitor.

Of course it didn't look good at 115% scaling.If you don't want to do scaling and want close as possible to 96 DPI, go for 2560x1440 at 31.5" , that works out to around 93 DPI

It took quite a while to pluck up the courage to try a 43" but I would never go back to 32" after using this one. The only downside I can think of is with dump apps that open up full screen (and games that also start with some stupid resolution, like 1080p).

content: I have thought about this too. Seems like 4k at full resolution could be great on a full screen. However all of the big 4k monitors use a BGR subpixel arrangement apparently, not RGB. Windows Cleartype is tuned for RGB and the results on BGR are said to be not great. I'm holding off until I can spend a bit of time in front of one and see how it really looks. Since most of my use is text it's an important point.Dell do have a 6k monitor coming this year. It's unlikely to cost as much as the Apple 6k Pro HDR monitor so it could be an option.

Played RDR2 for many hours enjoying the landscape on a horse- For desktop work I would now go a step smaller like around 34-36" because it is a nightmare moving the mouse and if you make the mouse go faster you are searching where it went.Also the 4 window mode (four full hd screens) it just doesn't work for me. Perhaps great for security guards watching cameras ir stockbrokers watching the markets, for windows, linux it becomes too small to do actual work.So if I had to rebuy today I would go for a step smaller but definitely bigger than 30".

content: I've been using a 40-inch Vizio V405-G9 TV on an RX570 for a few years now. I had to play around with the TV settings to get 4K RGB 4:4:4 at 60Hz. Since it is BGR subpixel, I had to use Adjust ClearType text (ClearType Text Tuner) to fix it. Otherwise, the text had horrible colour fringing.I use 125% scaling and the text is sharp on most applications. I often use additional scaling in the browser for a more comfortable read as I get tired. I spend most of the time in the browser and I never see any scaling artifacts. The exceptions are some very old applications that have unevenly scaled text. Some new applications ignore the scaling and end up with text that is too small to read.The Visio has a VA panel. Black levels are good in the darker room lighting I normally use. However, the viewing angle limitations of the panel are apparent. At my normal viewing distance of 1 to 1.5 m, the side edges of the panel have less contrast and saturation than the middle. In fact, if I look with one eye at a time, each eye sees a different amount of contrast and saturation for the same edge of the panel.I almost ruined the TV by letting it update its firmware. After the update, it lost the ability to display with 1:1 pixel mapping, rendering it useless as a PC monitor. Everything looked blurry and it couldn't be fixed in the settings. Fortunately, others have experienced the same problem before me and a Reddit user saved and shared an older working firmware.It works in 4K60 at 4:4:4 full range RGB in 8-bit mode connected by the HDMI port on the GPU. If I want 10 or 12 bpc (bits-per-channel), I need to switch to 4:2:2 or 4:2:0. I can chose these modes in AMD Adrenalin.Edit: bpc, not bpp. fixed

content: For my work laptop I have a USB-C hub which has 3 x DP outputs. In theory, it supports 3 simultaneous DP outputs (and I am using 2 x 4K60 with RGB in this configuration - I've *heard* it can do 3 outputs at 4K but not tested it), though Display Stream Compression is of course needed to achieve even one of those outputs. Still find it pretty incredible that this all goes over a miniscule Type C USB connector.

content: Quote from: tom66 on April 20, 2023, 09:32:25 amThe thing I hate about USB-C is, it's like they standardised the connector physical form, but while everyone attended that meeting all the different departments went their separate ways after that, because below the physical form there are dozens and dozens of different configurations. Some won't even let you draw a single mA, others it's your 500mA, yet another will give you 150W at 19.5V or more! Sometimes it's the cable, sometimes it's the device, sometimes it's a combination.My work laptop. With the screen closed I can run it on a 5V USB Charger. Draws about 18W. Open the screen however and it refuses to run on that or charge from it period. Plugging it into a QC3.0 9V smart charger port and again, screen closed "Ok", screen open "No way". Yet the screen is not pulling more than that QC3.0 port will deliver.It would seem for USB-C there are two options. Spend well once for something gauranteed to work, or spend again and again and again buying "nearly works" and "works there not here" type deals.Feel free to move to "Pet peeve thread"

content: Some extra notes, when using a TV as a computer screen:Scaling: You don't want to use scaling ever. It sucks and many applications are not compatible with a scaling factor different from 100%.Size: You should select a screen size that is equivalent in DPI of your current monitor. If you have a 24" FullHD screen, then a 48" (50") screen with 4K will have the same DPI and you don't need to use scaling. Consider that you now have 4 FullHD screens (2 side by side, 2 on top).Pixels: When buying the TV, note that some TV's use a different sub-pixel pattern than computer monitors. Go for a TV that has square pixels with the subpixels within each square. What I mean is this:OK:R R RG G GB B BNot OK:R G RB R BG B RYou get the idea.On my TV with current configuration (LG "Gaming Mode", HDR Mode, 60Hz) the screen is pretty much like my former Asus monitors. Red text on black or gray is okish/acceptable. Not perfect, but totally OK for me.The main selling point of this configuration is the screen/desktop real estate. You suddenly wonder how you were able to work on a FullHD screen before...As a side effect, I pretty much stopped using my HIFI Stereo connected via optical cable as sound source. The TV offers a pretty good sound for what it is and you don't need to setup speakers.The bad points, after 3rd week:1) I should sit a little bit higher. The top left and right corner of the TV are a bit too far and I need to move my head to properly read stuff. This is complaining at high level, though. I just put less important windows there, like when a CAM program is calculating. I will see when it is finished and meanwhile focus on the lower half and center of the screen.2) The TV does not have a standby mode like a computer monitor. If the PC sleeps/switches off the screen output, the TV will show a picture mentioning lack of input signal. This means I have to switch the TV off, before leaving my desk. This might move Outlook from the second screen to the main screen if I move the mouse to wake the PC before switching the TV back on.3) The TV sometimes shows events on top of the image (new FW available). This requires to take the remote and get rid of the message. This is a rare event, though.4) I need to cover my window during the day, as there are many reflections. I think I would have the same issue with most computer monitors.5) HDR mode revealed artifacts on the image I use on my desktop background, especially when looking at a certain angle. This is not the fault of the TV, but of the JPEG compression of the image. Means that you suddenly notice things like that.6) If you do online meetings and need to share your screen, make sure you have (as I have) a second FullHD screen connected, otherwise all participants won't be able to read anything, because they will look at a 4K screen on their FullHD screens.7) Some applications will render fonts way to big (i.e. VLC or VirtualBox). You can fix this by doing right click on the executable and editing the compatibility mode --> DPI settings.My other PC had a GeForce GTX960 and this card did not have enough RAM to run games in 4K mode. I am not a gamer and I just use Rockstar GTA V as a benchmark and to run away from the cops... With my new computer I have a RTX4070TI and GTA V runs on basically highest settings in 4K. Note that I would not spend this kind of money to play GTA V with better settings: the game plays exactly the same and I would say that the improved graphics are barely noticable during a regular gaming session.Overall this has been a great experience for me. I would not switch back to regular PC monitors. Note that my goal was to have the equivalent of 4 screens (5 actually, considering the extra monitor). It is not about having a bigger picture!

content: On ultrawide. In most window managers you can rapidly split apps left/right halves (LWin+<- ->). The aspect is such that you can have two perfectly normal looking apps side by side. Chrome even has an extension to single click this splitting the current tab into a sister sidebyside config.The annoying this is, YOU are part of the problem. Having a rare aspect ratio causes issues. An example is if someone, including me, forgets to set a particular setting when rendering the video file and then uploading to YouTube, the 21:9 capture of 21:9 content gets encoded as 21:9 content in a 16:9 frame with "pillar box" blanks. Of course when you open that on a 21:9 screen and full screen it, the player sees 16:9 and adds "prison bars" either side. The resulting takes up the centre half of the screen!

content: The single advantage I see with multiple monitors is being able to max a window to only that monitor. If that's what you need to do - perhaps having a main app maxed on there with supporting stuff on the others - it works well.But having now tried a massive desktop I wouldn't go back to multiple smaller ones. One major reason is because the screen bezels sit smack in the middle of your workspace if you don't have a master screen. And if you do have a master screen you're stuck with the in the middle and the other(s) off to one side. Whilst you can technically spread an app across two screens, that bezel gets in the way, so realistically the maximum size for a window is a single screen.On the 4K I can have it any way I want, wherever I want. As I said earlier, the only real downside is some app starting up maxed, but once tamed it's a non-issue.

content: Quote from: PlainName on April 20, 2023, 02:29:33 pmThe problem is that you cannot see the whole wide screen at once. With two monitors you can use main monitor straight in front of you for most things and put another monitor under angle so you basically switch between the two and have comfortable viewing distance for both. With ultra wide one, you cannot see all of it at once anyway, and with a downside that it's right and left side are uncomfortably far away compared to center of the screen. Even super curved screens are not that curved to mitigate that, and strong curvature is a whole another issue that may bog you. App toolbars located on the sides only makes it worse. So you may end up only using middle of the screen in most cases and waste the rest of the area. It may be decent for some sorts of gaming like racing though if center of the screen is what you want to look at most of the time. Modern monitor bezels are small, so you can easily have only like 1-1.5cm wide dead area between the monitors.

I spend most of my days with one monitor extending off the work laptop and the other my personal PC. (Part of me wishes Synergy was free and could get past the work laptop firewall).It's also very nice while gaming. The vast majority of AAA titles will lock you into full screen and barely support "windowed" mode even if you beg them. Most will allow non-exclusive or boundary less full screen, such that you can with a bit of effort, free your mouse from the game and still click in the other screen.I have also run 2 copies of a full screen game one on each monitor. Eve Online. Not a small game!

With three previous monitors in an L I could angle the side one a bit, but all that does is fix my head position since moving at all would ruin the arrangement.With my current monitor I often have three Word windows open side-by-side that fill the full width of the screen. The one I am working in is in the middle and the other two are for reference/searching. Don't have a problem treating any of them equally. In some ways it is better than separate monitors because it doesn't extend so far to the sides (that is, it's as if the entire display setup is moved to the middle, but with no bezel to get in the way).And just to round things off I do actually have another monitor, a tiny 7" 1280x720, which is perched on the top and carries a calendar plus some performance monitoring gadgets. And I use virtual desktops too

content: Quote[note: this is not a 43 x 32 comment]Main issue with that kind of setup is the limit on window height. My driver for going single monitor, as opposed to the three I already had, was the amount of space stuff like ribbons and that can take. A 4K screen gives you those extra pixels so you no longer care so much about window furniture.Also, I think power use is a bit less then multi-smaller monitors. Not by an awful lot, but every watt helps.There is a downside if you use virtual desktops. I used to have mine so the main monitor would switch but the side monitor wouldn't, thus I could switch between, say, two desktops on the main monitor but the peripheral monitors would always stay the same. With the single big screen that's not possible - it is one desktop or another. Mitigating that... you can have both desktops showing at the same timeAs I noted above, I resolved it for me by having a tiny satellite monitor to hold non-virtual stuff, but horse for courses.

I tried it, can't get it setup to look normal on an SDR desktop so I switched it back off for now. It honestly looks like it's reducing the SD content's dynamic range making it look washed out, weak in saturation and too bright. If you take the SD region slider down so it's not too bright it really looks weak, contrastless and virtually no saturation. If I turn the NVidia "Digital Vibrance" to 0% the screen is black and white. I think I need to do some reading up on how to set it up properly, for now it's off, which is anything is too vibrant and could use the Digital Vibrance turned down!It has working speakers which was a pleasant surprise.

It will play content fine, but if you start skipping back and forth, full screen, back to desktop, full screen and so on, the GPU will thermal throttle and frame start to get dropped all over the place. I took it apart, checked, cleaned the fan, reassemled and sealed up an air leak with captan tape between the fan and cooler. Hopefully it will hold out.

content: To whom it might interest:I now am using an LG 50" 4K TV as my main monitor, together with a second 22" FullHD monitor for more than 2 months.The experience has been great and I am actually sad, I did not go this route much sooner.The external 22" monitor is used for Outlook and for remote calls where I need to share my screen. You do not want to share a 4K resolution screen, as the other parties won't be able to read anything on their FulHD (or less) screens.The other oddities or less good things:1) The TV does not have a standby mode as we know it from computer monitors, that switch to standby in the absence of a signal. The TV will instead switch to a default screen, complaining there is no signal. It means that I have to switch off the TV when going for lunch or at the end of the day.2) The TV will notify me every 4h that it will switch off unless a key on the remote is pressed. This is a bit annoying, but on the other hand, it alerts me that I have been sitting for 4h straight and it is time to do a break.3) The HDR does not work 100% and I think it is a Windows 11 problem. Sometimes, depending if I open i.e. Chrome, the screen will change brightness and colour space. A bit annoying but not that big of a deal. You get used to it.4) Some applications insist in starting in full screen mode and you need to minimize them/size them according to needs.The great about using this TV as the main screen:1) It is literally as if you had 4x 24" FullHD monitors without the frame in the middle. You get so much desktop space, that you never again need to minimize applications. They all fit!2) Initially I was worried with having 4 apps each in its corner running in FullHD and how much of a deal it was to get them all in their position. After some days, I naturally stopped worrying about that! I just put the window where I need it with the exact size I need it. There is enough space for everything to fit.3) Some few applications really benefit from running maximized: I develop manuals in Word and being able to see up to 8 readable pages is amazing. The same for huge Excel sheets.4) I do work (hobby level mainly) with TV related applications and of course it is great to be able to see a 4K video stream in all its glory.5) I have not played games so much, but the few I tried are much more immersive if you are sitting at about 1m from a 50" screen.Some further notes:My previous graphics card did not have enough memory to benefit from 4K resolution for games. You need a good graphics card to really benefit from the screen. I am using a RTX4070TI.With 60Hz, the screen refresh rate is perfectly OK for me, perhaps gamers or special application require more than that and in that case, t he screen would not be suitable.The colours are OK in HDR mode, including red text or text on red background. That was a bit of an issue without HDR active.Finally:Sitting in front such a big screen and so close to it (1m), does cause some strain on your eyes. I use the screen always in might mode (reduces blue light) and even so, I notice some strain after long sessions. But: on my previous setup (which I still have next to me), with 2x FullHD + 1x 1280x1024 screen, had the problem that it was becoming difficult to read the screen.The same goes with my laptop with a second external screen: To read the laptop screen I need to remove the glasses (too close - I am short sighted and with age I no longer can see at short distance through the glasses), but then I cannot read the external screen (too far away). With the 50" TV I can always see everything with glasses.The other option would be getting progressive glasses, but those just average the problem: you won't see great neither in short nor long distance, plus I would require much bigger and heavier lenses.When selecting the screen, consider dpi: do not buy a 4K screen with 32": everything will be too small and with windows scaling you enter a whole new world of problems. Consider the ideal FullHD screen size (i.e. 24") and multiply into a 2x2 grid and you reach a 48" screen. Do measure your desk! In store the TV's seem smaller than they really are. I wanted to buy a 55" screen initially, for bigger text size, but such a TV would not fit!Regards,Vitor

content: I was able to tame it a little.The blue annotation lines, from L to R,"Disable low latency mode" - drops 50W probably lowering the DSP clock."Lower brightness to 0 then raise to 10 (from 50). Drops 100W!"Disable Smart controls for brightness and contrast" - basically with these on, it overrides the brightness setting.So as I'm only dealing with an agregate power value and not the monitor specifically these are all "ball park".If it was pulling 180W it should now only be pulling 30-40W.2x Worklaptops = 60W1x Gaming PC @ idle = 100WLED lights, auxiliary gubbins, 30W or so.That leaves about 60W for the monitor which is... acceptible.Your post had a tone which set me off on proving you wrong.However it didn't. It proved you were right and the brightness settings had a massive impact. Maybe I should have realised I was dealing with a "nice" monitor which will come out of the box with everything maxed out in the "Wow!" factor.It's ironic that it constantly gives you a speach about USB standby power when you turn it on, but defaults to 180W!

content: Quote from: Bicurico on June 05, 2023, 10:31:22 amYes. The PC has to be capable of driving the display.For example, the "energy austerity" PC I use on dull days draws only 8-13W. It "will" produce a 4K@60Hz display over DisplayPort (only), I will also produce a 1440p ultrawide display at 60Hz but... I ended up dropping it to 1080p.Why? At 1440p the desktop is fine. However if you open YouTube and stream 1080p content it works "ok" windowed, but hitting full screen and it can take 5-10 seconds before it actually goes full screen. Then it will drop frames like crazy for a few seconds, stabilise and be "ok" for 5 minutes or so until the APU die temp gets up and the clock throttles then it's back to dropping frames. At 4K@60Hz this was un-usable. At 1440p@60Hz it was still irriating enough to go down to 1080p where it's perfect.It will not game period.Obviously the 2022 top spec gaming PC with a 3080 doesn't care at 4k@100hz pulling 500W gaming.However. You don't need to go to the extremes of 3080s if you don't want to game, if you want a solid, responsive 4K@60Hz display output to drive a 4KTV over HDMI you can get away with a Gtx1030. I use these in the living room and bedroom to do that with Dell eWaste boxes.With a Gtx1030 in a Dell Optiplex 7010 with an intel i3 3rd gen "T" class CPU, think it's an i3-3200T maybe? It does 4K60Hz with HDR responsively. The HDR can ocassionally cause video lag, but it's normally fine.If only low profile 1030s or 1650s weren't still over £100 a pop!

content: Quote from: paulca on June 05, 2023, 09:52:53 amThat is something i have noticed with our meeting room setups. Large screens, 65" and larger. Hold your hand to the display and you can feel the heat it radiates, you do not even have to touch it.

content: Quote from: paulca on June 05, 2023, 09:52:53 amThat's terrible. Can't remember the exact figure for mine (Iiyama X4372UHSU) but it came out the same as two of the three sceeens it was replacing, so 50-75W. Checking the manual it says "80W typical", so that ties with my memory.As to the other issues... glad I the Philips was too expensive when I was looking for one

content: Quote from: Ranayna on June 05, 2023, 12:40:35 pmWe have an 80" LCD, 4K, in the boardroom. So often it gets left switched on showing "no signal" showing pretty pictures of landscapes, according to the datasheet that pulls about 300W in average usage. So no surprise they're hot to the touch.

content: Phillips blaming is quite stupid. Basically all TV/monitor manufacturers use more or less the same LCD panels from the same suppliers. So similarly specced monitors and TVs manufactured at similar time will have roughly the same power consumption if settings are similar. It's like taking two 1000W heaters, setting one to 50% power and then blaming one set to 100% for consuming too much power. Also do not forget that LCD with same size can have quite a bit different maximum brightness. So one that is much brighter is capable drawing quite a bit more power too. But complaining about max power due to max brightness is stupid because if you lower the brightness to the level of a less bright panel, it will likely consume less power than that.

content: Well. It's not like I am comparing like for like.The Philips is NOT the same panel type of the Samsung. Nor it is the same manufacturer. If I am lead correctly, Samsung make their own panels and TPV make panels for Philips.The phillips has a multi segmented backlight. The samsung goes not. The philips is HDR the samsung is not.The samsung runs on a 70W DC brick. The Philips has it's own IEC mains cable.One runs cool off a 12V car battery, the other heats the room up and brings the fan on 600W inverter!I don't care if it's made by Philips of ACME, its power usage is excessive in default configuration.

content: Samsung usually uses their own panels only for high end products. In general more likely you'll find something like BOE or Innolux inside.

content: BTW Samsung stopped producing usual LCD panels last year, so if it's not quantum dot LCD or OLED, there is no chance to have a Samsung panel inside.QuoteYour Samsung likely came with 100% brightness setting by default and you just don't remember that.

content: Quote from: wraper on June 05, 2023, 01:44:15 pmYou are correct. However. It still is in full 100% brightness with Samsung smart brightness and all the bells and whistles turned on. It pulls around 30W.Again, not saying they are like for like. The Philips is an HDR monitor so has far brighter backlights. The Philips has sectional backlighting. If a game opens with a small white logo in the centre a square of backlight bleed can be seen only in the centre. If that logo is wider than about 30% of the screen then a whole row across the centre can be seen. I believe it also explains the "contrast" ghosts across the screen.I'm pretty sure the Samsung has a single standard LED backlight around the edges.So 43" in SDR mode @4K and 10% brightness = 65W.To be honest it looks the same brightness to me. As I mentioned though, at 10% brightness the color calibration isn't great. The forum background looks almost pink or rosey coloured. I partly fixed that by readjusting the Gamma and colour temp, might need more tuning.
