[Asus  Eee Pad Transformer Prime] buxtahuda:
This is why I think it is an issue of software more than anything. I do know that screens by default will be cooler or warmer than another; my identical LG LED monitors are just the slightest bit different. But the issue with washing out is something I did not notice in the few hours I was able to use my Prime and root it before it updated.

Yes, some will be slightly "defective," but I'm waiting for this next update and some homebrew'in ROM love after the unlocker. Then we'll truly see what's going on.
[Asus  Eee Pad Transformer Prime] buxtahuda:
It's not as noticeable as it really is, dig?

I think it's clearest on magenta there, this is on Performance and SuperIPS.

The reason I'm doing it that way is that the picture is aweful without the SuperIPS on, when side-by-side to my LED screens.

Power saving + SuperIPS. More noticeable, but still doesn't look as bad as it does on the naked eye ;)

Side-by-Side [Power saving | Performance]
[Asus  Eee Pad Transformer Prime] undercover:
Any suggestions as how to name it?
[Asus  Eee Pad Transformer Prime] undercover:
Your one is good, very good. I'll post mine in the evening.

Now to determine wherever it is sw problem, we need to see if all of primes are the same, and if they are not, do panels differ or not. If panels are different, then possibly it is software. If panels are identical, then we have same sw, same panel, different colours = bad screen.
[Asus  Eee Pad Transformer Prime] Justin_Thyme:
You cant just compare the colors on two different devices and say its the primes screen. There isnt a single display/graphics card on the market that displays colors correctly uncalibrated, regardless of how much you paid for it. With most displays the colors will be affected by the luminance levels. Most people adjust their displays for higher contrast and more saturation than what is actually true which can make other devices look pale or washed out. Im a professional photographer and know all to well that you cant use and uncalibrated monitor/grahics card combination for color adjustment in the photos. Ive seen many people over the years blame their cameras or printers for bad colors in photos when in reality it was the fact that an uncalibrated monitor was used in post processing. I use Xrite colormunki calibration tools on my PC and printer to make sure that what you see is what you get and its all true colors. This solution uses an optical measuring device and sends color offest values to the grahics card and print drivers. Any color variations are defnitely a matter of drivers to the display and unfortunately there are no adjustments available on android tablets although Spyder did release an app for Ipads.
[Asus  Eee Pad Transformer Prime] undercover:
I understand where you are coming from. It's not realistic to expect everyone to have calibrated screen. And yes, colours will vary between computer screens.

I had 4 primes, so I do have something to compare it to. I didn't notice anything like that with the first two, but it was obvious with last two.

Also, I compared it to all devices I have, and every device outperformed prime in regards to colour reproduction, especially red and blue.

Could you check yours with colormunki or against your calibrated screen please?

I really hope it's down to software, but I can't afford to gamble £500 on it.

I had some prints done professionally and compared them to my screen, so my screen is fairly close to real colours.
[Asus  Eee Pad Transformer Prime] Bumble-Bee:
Hello,

Iv noticed the colours getting washed out (on mine power saving mode). Tegra3 and i think newer tegra2's have a kernel driver that can actively change the display properties to save power on the unit (in exactly the same way nvidia GPU drivers do it)

U can check this on your devices by doing the following

** dc is part of the tegra display driver (kernel space)

Changing between power saving --> balanced --> performance shows that a lot of properties are changes .... unforrtunatly there seems to be VERY little documentation on these drivers and how to control them

In any case my tfp is pretty good colour wise while on balanced / performance ;)
[Asus  Eee Pad Transformer Prime] undercover:
Hi there. I appreciate your reply. In my case, it's power saver which gives better colours, and two others just wash them out. Saying that, even on power saver colours are not very good.
[Asus  Eee Pad Transformer Prime] jaypm:
maybe just "TFP screen - color performance" ?
[Asus  Eee Pad Transformer Prime] Bumble-Bee:
The driver seems to allow calibration of the screen ..... im going to look at the drivers to see if we can make use if this :)
[Asus  Eee Pad Transformer Prime] undercover:
Niiiice. If you are quick with that (not that I'm rushing you) my otherwise perfect prime might be a keeper. I still have few days of buyers remorse left.

On the sidenote, has anyone else tried test in op? I'll post pictures tonight, and then will do factory reset, let's see if that changes anything, maybe transition from HC to ICS wasn't smooth. Who knows.

Ok here are the pic

*note my PC screen is very bad at the 75% grey
[Asus  Eee Pad Transformer Prime] Spidey01:
retards question between quick scrolls, but what app is/apps are being used for testing this stuff?
[Asus  Eee Pad Transformer Prime] undercover:
You just compare pictures in op to your pc/laptop screen.

Just took some pics with my phone, it distorts colours, so you can't really see any difference. Will have to take my dslr out..
[Asus  Eee Pad Transformer Prime] buxtahuda:
I guess that's the issue with my pics as well. Because it's like twice as bad as they make it out to be. Might get out my brother's DSLR as well...

And is there no free-ish something that will calibrate colors for screens/printers? I feel terribly retarded having never even thought of my screens' colors needing calibrating, but my brother and I do so much digitally that we generally don't see the end result on anything but our screens. I also feel terribly beaten by a $500 price tag on a bit of (albeit pretty in-expendable) software.
[Asus  Eee Pad Transformer Prime] undercover:
Update. Done factory reset, nothing changed. It's bloody Annoying.

Apache, your screen looks as bad as mine. Could someone with what he considers a good screen with good colours post a good quality picture here please? I'm really, really desperate to determine wherever all of them are like that before my return window closes.
[Asus  Eee Pad Transformer Prime] demandarin:
I seriously agree with this post. I tried the op test out also. Colors look great on my prime. I did compare to my Atrix 4g. Very similar but Atrix colors are a bit more saturated or darker looked. You have to consider screen size also. All devices will have a different color pallets. Prime has more natural colors compared to ipad2, whose colors are very saturated and cartoonish looking. Same with Samsung Amoled colors. But there is a degrading in contrast and quality when in power savings mode. I love to have my high Res wallpapers looking their best so i always use either balanced or performance mode. I'm a amatuer photographer of sorts also. So i do see where you coming from. But the prime display still looks great to me. There's a reason why its considered to have the best display of any tablet out now. It has the brightest display, highest contrast ratio, and highest dpi of any tablet out. Pictures n everything just look great on the prime. I love how good it looks. Blows my Ipad n atrix display away.
[Asus  Eee Pad Transformer Prime] buxtahuda:
Will get the DSLR out and get better photos.

Again, anyone know of some kind of free color calibration?
[Asus  Eee Pad Transformer Prime] leppie:
Most LCD controllers require calibration on device power up. I am pretty sure there is something in the kernel doing that all ready.

Also look for how the driver info is exported to the sysfs.

Oh I wish I could have my prime back from RMA now :(
[Asus  Eee Pad Transformer Prime] d1ez3:
The update today (.13) I swear has fixed my color issue. The colors finally look awesome. Anyone else see this?

Edit: I could be wrong and just delirious from studying for graduate exam all day lol, hard to be sure.
[Asus  Eee Pad Transformer Prime] aznmode:
I've had 2 primes with 2 different screens. One had a yellowish tint and the other had bluish tint. The bluish tint had better contrast.
[Asus  Eee Pad Transformer Prime] undercover:
Just compare it to pc. You need some sort of reference.

Blimey, how do I get that update? It's US only afaik.
[Asus  Eee Pad Transformer Prime] undercover:
See,my screen is not what I'd call yellowish, but it looks that due to poor colours it lacks contrast.
[Asus  Eee Pad Transformer Prime] undercover:
Hmmmm, just took some pics with dslr. Colours lookidentical on the picture. For some reason i just can't take picture which would reflect what naked eye sees. So, no on else noticed anthing like that, only a few of us?
[Asus  Eee Pad Transformer Prime] NeoteriX:
There is a lot of talk, but I haven't seen any photos of two TF Primes side by side showing any variation in saturation, contrast, gamut, whatever.
[Asus  Eee Pad Transformer Prime] aznmode:
Unfortunately I already returned the one with the bluish tint. It had serial bcokasxxx. The one i have now is C1xxxxxxx and has a yellow/warmer tones. I also compared the Prime to my acer a100 and the reds and blue are definitely more washed out on the prime. i tried taking a picture but you cant really tell but the acer has a bluish tint and reds and blues are deeper. The way to also tell is the clock color is more blue on the prime with bluish tint.
[Asus  Eee Pad Transformer Prime] undercover:
So there are a few of us. :( mine is going back tomorrow. If gTab had an expansion slot, that would be a no brainer for me. As it stands, i'm not prepared to gamble again until new batch is out.
[Asus  Eee Pad Transformer Prime] NeoteriX:
The problem is here, and I'm not picking on you in particular, is that photographic comparisons with computer monitors are meaningless. We can see that there's a difference, but there is no appreciable way to determine which screen is objectively better or what the meaning is in the perceivable difference.

I'm sure you could take any two monitors, both that would look subjectively "good", line them up side by side and show a similar difference. The same goes for a monitor and something like an iPad (assuming iPads are known to have decent image quality).

The usefulness in comparing two Primes side by side is that even though we cannot tell objectively, which has the better screen quality (due to the above discussed and limitations with digital camera capture), we can tell how much of a difference there is, and at a minimum, that is useful to determine the kind of variation in panels that exists in the same model.

In other words, we need to keep at least something constant for there to be useful analysis, and keeping the model constant (the Prime) is the only thing to be done here.

Everything else involves taking people's word for it, and while that's nice and all, people's eyes and sensitivity to color vary on an individual and biological level and it is useless for making concrete, scientific conclusions.
[Asus  Eee Pad Transformer Prime] undercover:
Well, unless everyone picks up colour card, which is used by photographers, there is now way to have some sort of continuity.

Unfortunately, we can only go by what people say. There are posts on internet where people compared primes, no pics unfortunately, and there was difference, and not just in one unit.
[Asus  Eee Pad Transformer Prime] NeoteriX:
The color card is meaningless as well (especially as shown here in this thread), because we are not standardizing the digital capture. The appearance of the color cards only show that there is a difference, not what the difference means because the cards themselves, the color temperatures of the different screens, the different brightness/intensities of the screens, the ambient color temperature of the lighting or absence thereof, all these things will affect exposure and white balance.

When photographers use color cards, they are standardized printed cards (printed to be color accurate and with an accurate grey point comparison border), and they are photographing them with a specific lighting temperature. These are standards that are crucial for the comparison of film or digital sensors as we are holding certain elements constant.

What are are doing here has nothing held constant.
[Asus  Eee Pad Transformer Prime] undercover:
I meant printed ones. So my statement stands. :)

Look, wherever we trust ones word or not, when he says he can see the difference between devices, he most likely can. I wouldn't start that thread if I didn't see the difference between two first units and last two.
[Asus  Eee Pad Transformer Prime] maddog986:
My wife has a Galaxy Tab 10.1 and the other night we where sitting in the living room and she noticed from across the room how much more yellow my Prime is. Side by side its really bad. Even my older DroidX looks better.

When im using the Prime i dont notice it much unless there is another device near by... Then it gets really bad.

Im hoping its just ICS and either Asus fixes it or in the future we get some custom roms that fix it. *crosses fingers its just a software bug*
[Asus  Eee Pad Transformer Prime] ultratek:
ips+

I am kinda living by the colors are alright if you use ips+ but for the most part the colors are desaturated on the tf201 even mine.
[Asus  Eee Pad Transformer Prime] buxtahuda:
I don't see it being an ICS or software bug... Although I could see giving users control over their screens and helping us tweak our Primes to at least be close enough to par with our other devices.

Either Google with options in ICS, or our dev's with some kind of "spare parts," will hopefully give us some real customization over our displays.
[Asus  Eee Pad Transformer Prime] aznmode:
Agreed. I have seen screen differences in variety of devices including phones. I first started noticing manufacturers using different screens back in the Treo 650 days. Even on, Treo 700, Touch Pro, Touch Pro 2, Evo 4g. The only way I was really able to know this is because I've had advanced replacement sent to me on each one of those phones and was able to compare side to side. In most cases I would ask for a replacement because they would send me the screen I didn't like or that didn't look like my previous. Unfortunately I cant do this with the prime since they really dont do advance replacement.

And also TV manufacturers are knows to use different panels. Samsung being one of them. I've went through several exchanges with those also. One with my A750, then last year with the C630 series. This is well known and documented on avsforum.com.

Also agree with the previous poster about comparing 2 different devices but its the closest comparison I had.

I think what's shipping out now are the warmer screens (C1xxxxxx serial #s). It's possible some of those had the cooler(bluish) screens. But there's a chance we'll never see those cooler screens for a while or maybe never. Serial # BCOKASxxx I think had better chance of having the bluish screens. Doubt you can find one of those anymore.
[Asus  Eee Pad Transformer Prime] :
All I can say is at full brightness, medium and low, I compared the prime with both TF101 and Galaxy Tab 10.1 (which both have antiglare screen protectors) and the Prime's white looks cream compared to the other two.

Edit: Mine is BC0KAS
[Asus  Eee Pad Transformer Prime] aznmode:
That's what is being referred as warm tones. Like warm setting on your TV. So whites are slightly toned down
[Asus  Eee Pad Transformer Prime] undercover:
Update. Reverted to HC just to see if colours improved. Nope. Nada. Nothing. Same crap. The only reason it wasn't as noticeable on HC (some people claimed .33 and ics spoiled the colours) is because blue in Honeycomb is a lot more intense than light blue in ICS.

Glad I wasn't able to return tablet today (there was no manager to authorise a return) so i could test that. But it's still going back ASAP.

P.S. I STILL haven't found a way to get panel id. dmesg in terminal doesn't seem to do anything, dmesg | grep panel doesn't do anything either, rooted or not...
[Asus  Eee Pad Transformer Prime] aznmode:
Wait back up a bit!...You downgraded from ICS to HC?! Did you use this method here? More details pretty pls....

And yes the color doesnt have anything to do with firmware IMO cause the 2 tablets I had at the time both had HC .33

Edit: The other tablet was HC .27....my bad. But on HC .33 in setting> about tablet there should be LCD information. But this might not really tell much if the screen manufacturer used a different front panel.
[Asus  Eee Pad Transformer Prime] undercover:
Correct. That method. It's pretty simple. If you hit bootloops like I did, just wipe data from.recovery (power + -vol)

Edit. It's a good idea to compare models from "about tablet". What's yours?

Someone with "good colours",what is your panel type from "about tablet"?
[Asus  Eee Pad Transformer Prime] aznmode:
Well this one I have is the warm screen but still on HC .27 which doesnt show LCD info but I will update it to .33 via that method. Hopefully I wont F anything up lol. Crap wait a minute...wipe data??? This may take longer than I thought.

EDIT: NM thats if I hit bootloops.
[Asus  Eee Pad Transformer Prime] undercover:
I was going "down" from ICS. Going "up" on the same base probably wouldn't cause that.

[Asus  Eee Pad Transformer Prime] buxtahuda:
Well, mine is MXT-2.0 build-170

My Prime is warm, but it's not noticeable to anyone else... Held side-by-side with my phone and monitor, the Prime is barely creamy (this is on Balanced and 50% brightness) compared to the LED monitor, and the phone is so cool it's crazy haha

I may try to get a picture, and I know it doesn't mean much to some people, but seeing a generally accurate monitor next to these two screens is pretty wild (to me... I had never considered my phone's colors cool before haha)
[Asus  Eee Pad Transformer Prime] aznmode:
Finally got a chance to work on it. I'm on. 33 now. Touch panel version MTX-2.0 build-170. Warm screen. But I mightve been mistaken, this version I think is the touch panel and not the IPS screen. So this might be moot.
[Asus  Eee Pad Transformer Prime] aznmode:
This was posted by anther member talking about GPS but I think this is the comparison sample were looking for. If you look at the whites on the left tablet they are bluish. If you look at the battery icon its more blue than the right.

Just wanted to add to the screen convo. I have noticed when i go from a primarily dark background to a lighter one my colors are washed out for about 4 or 5 seconds while the screen adjusts itself. Try it yourself by going from the settings menu then back to home with the winter tree as your wallpaper. Or go from playing a video back to the file manager screen.

On mine it's so washed out that the black text is barely legible. This soon corrects itself though. At least with my Prime.

I too am really into screens and I absolutely love screens with great colors. I was so sad when I saw how terrible the colors were on my prime when I got it. I used to own the galaxy 10.1 with gorgeos colors, and comparing the prime to my 95% color gamut monitors makes it look pathetic. I sure hope, in the future, that there will be some kind of calibrating tool or whatever to correct some of the colors.

Did I just get a bad screen or are all prime screens this bad?
[Asus  Eee Pad Transformer Prime] dragonithe:
I'm also not 100% happy about the screen of the prime.

The washed out colors where actually almost the first thing in noticed on the prime.

Maybe it's because I've got a Amoled Desire, and amoled seems to be very saturated, but even comparded to my desktop monitor it looks washed out.

It doesn't bother me as much as it used to do but it's still a little of a pain.

I ordered a replacement from Amazon, except this time I went with the Champaign color and I received a C20 model which I received on 3/2. The screen on this one is absolutley stunning, super rich colors and I would say it was 20-30% brighter than my first Prime.

You just won the lottery. Take care of that thing cause the likelihood of getting the same screen is slim.
[Asus  Eee Pad Transformer Prime] Ready2Mosh:
I actually felt that way when I had them side by side, I couldn't believe the difference. I used colorful games like angry birds Rio, whale trail, fruit ninja, and big buck bunny in 1080p. First test was with brightness all the way down and in power save mode, second one was mid brightness with the middle power option and finally all the way up with and without super ips on.

The Champaign smoked it in every way.
[Asus  Eee Pad Transformer Prime] Ready2Mosh:
Well, this one is going back, it has developed hairline cracks along the left side on the black bezel, they aren't all the way through and can only be seen in certain light, but they will spread in time and I'm not going to risk a $400 repair on something I didn't do due to a defect in the glass.

I'm out for now, not going to keep doing this hoping to hit the lottery again, what a shame!
