Dude, just read what the product is. The first two are MHL dongles...

The Nexus 4 uses Slimport.
[Nexus 4 Accessories] smirkis:
the nexus 4 has a slimport, so you obviously need a "slimport" usb product. MHL wont work, or isn't supposed to anyway
[Nexus 4 Accessories] dinged:
Slimport is a trademarked term and it's an extension of MHL. It's an extension to provide 1080p. My question is valid bc I'm inquiring if there's backward compatibility so that I can purchase the lower resolution, significantly cheaper MHL cable. I'm sure there are many others who would also want to go this cheaper route and can do without the sarcasm.

So in that case....it's not so "obvious".

Additionally, isn't it plausible that you can use the same pin terminations as the cheaper MHL dongle and the Slimport technology is built into the phone itself and has nothing to do with the microUSB-to-hdmi dongle?

Why are so many "senior members" so arrogant to bash a post?

Slimport

I received my Slimport adapter and can confirm it does not require power, it does however charge in USB mode. :(

However, I do notice a loss in performance, like it splits the frames, rather than cloning. Meaning, I get 30 fps on both my TV and phone, whereas my phone would get full 60 when not using the adapter.

This really bothers me when gaming comes to mind.
[Nexus 4 Accessories] smirkis:
sounds like u have a mhl adapter. or lack of english
[Nexus 4 Accessories] Admiralcurtis:
I'll try again, since my terrible English isn't good enough.

I bought and have received the Slim-port adapter. The Slim-port adapter will transfer a video and audio signal to a television without a USB power cable plugged into it. The Slim-Port adapter charges the phone in USB mode while a USB power adapter is plugged into the Slim-Port adapter.

When the Slim-Port adapter is in use, it lowers the overall performance of the phone by half, games will run at 30 frames per second on both the phone and the television, instead of the 60 frames per second it should, causing a slow down.

In addition, when I had the Galaxy Nexus before this, I used a MHL adapter, games would run at full 60 FPS without a hiccup.
[Nexus 4 Accessories] steslatt:
I have been using the slimport adapter for around 2 weeks now. I use it a lot for streaming videos off my network harddrive. The performance so far has been poor compared to my galaxy s2. I'm not sure if this is down to the adapter, the fact that I am streaming or the phone itself. I am starting to do tests now to determine the problem.

Basically if I use a video player with HW decoding I get poor frame rates, if i change to SW decoding it seems to work ok. However even when the adapter is connected to a power source the battery runs out faster than it can charge :/ I have got round this for now by using screen standby app which turns the screen off on my phone while connected to hdmi.

Do I have any need for a slim port adapter??
[Nexus 4 Accessories] momendo:
This should be a FAQ made sticky.

1. SlimPort (MyDP) is not MHL. They're two different standards pushed by different groups. You will need to buy a new dongle. They are not interoperable.

2. SlimPort is DisplayPort based technology. It can transmit uncompressed DisplayPort, VGA, single link DVI and HDMI signals.

3. You don't need active power attached for the SlimPort dongle to work unlike MHL adapters. You can add USB power to the dongle and it will charge the phone. The dongle even takes 2 amps from my iPad charger where my MHL adapter had to be exactly 500 milliamps to operate. It's better to charge the phone when watching long movies. It says "Charging (USB)" in the settings pull down panel when I connect the micro USB charger to the Slimport micro USB port. When I connect the micro USB charger directly to the phone, it says "Charging (AC)".

4. The Nexus 4 transmits a landscape 1920x1080p 60Hz signal (v-sync off it appears) and stretches the 1280x768p in that area. There are black pillars on the left and right sides. On the home screen and in most applications, the HDMI output mirrors what is seen on the Nexus 4 screen. There is a noticeable frame rate slowdown on the HDMI screen to my eyes. Some apps that play movies will display full resolution 1080p movies over HDMI while displaying cover art on the phone screen rather than mirror. The Nexus 4 screen is always on when connected to the dongle. I recommend reducing brightness on the phone if you care about LCD burn in.

5. The HDMI signal on the Nexus 4 has always-on HDCP copy protection. If your HDMI monitor doesn't support HDCP, you may see a black screen. Check your monitor manual for support.

6. Like MHL, stereo audio and 5.1 audio in some apps can transmit LPCM digitally through the port.

7. VESA says in their press releases that there is a 1Mb data side channel for accessories. Though on the Nexus I don't think that feature is supported.

8. The Nexus 4 doesn't support USB OTG or USB devices. Connecting a USB keyboard or mouse to the micro USB port on the Slimport dongle will not work. Use a bluetooth mouse or keyboard if you need this functionality.

[Nexus 4 Accessories] kayateia:
Has anyone heard any news about the VGA adapter? It seems like they were all over the place in reviewer circles, but they're not for sale yet. I'm wondering if it supports different resolutions, or if it forces a high HD resolution. I've got an old projector that natively takes 1024x768... the 768 is okay for native N4 resolution, but 1280 might be too high for it. ^^;

Also, for anyone who has the HDMI one already, is it always a display mirror? Or do some apps allow you to do things like have controls on the N4 and video output on the external? That would be a really nice feature too.

Hi all, just to say that I bought one of these from ebay last week...

"MICRO-USB TO HDMI MOBILE HIGH DEFINITION LINK ADAPTER FOR LG GOOGLE NEXUS 4 E960"

http://www.ebay.co.uk/itm/321018193526?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

It arrived yesterday much to my excitement. Excitement that was soon dashed however as even though it is listed as being LG Nexus 4 compatible it's a MHL adapter and not Slim Port one and therefore it does not work! Tried 3 different HDMI leads and four different TV's.

I've advised the seller to remove or edit the listing.

At £13 I thought it was too good to be true! Pity it was..............

Nexus 4 to slimport to HDMI to HDMI/composite converter to composite cables to monitor

Please share the exact converter you bought.

My issue is that I want to get Netflix and Google play movies to play on my van's VES for my kids, but the van only has composite in. I bought a slimport adapter and it works great on my wife's N4, my N5 and N7 when plugging the HDMI cable to the TV's HDMI port, but won't display anything through the converter. I plugged my HDMI cable box cord into the converter and it displayed just fine on the TV, but the slimport won't. So I'm at a loss as to why the converter works for all my other HDMI devices I tested other than the slimport.

This is the slimport I bought

I bought a VGA slimport and am wondering if anyone else has this problem-- So in CM it crashes (have given up, and thankfully for multirom could easily just go back to stock), and in stock 4.3 my monitor displays this ridic message "cannot display this video mode // Optimum resolution 1280x1024 60Hz"

That said, my laptop can display whatever resolution I want (pretty much) on this monitor. I also have changed the DPI a few times and the resolution with various (density changer, lcddensity, resolution changer) apps to no avail. Also tried my friend's monitor and it didn't display anything (no error message, just blank/backlight on screen)

Does anyone have a working vga slimport?

[Nexus 4 Accessories] karasuhebi:
From what I read a while back, that is not possible since the microUSB plug on the myDP adapter only allows for charging, not data, so you can't plug a OTG cable into it.
[Nexus 4 Accessories] TheManii:
Slimport takes over the usb pins so there are physically not enough available pins to do more then one thing at a time.

MHL 11 pin does this by having, well 11 pins.

The extra pins on that allow it to do multiple things at the same time.

myDP/slimport simply reuses the existing pins without adding addtional ones.

Haven't seen a reply yet, so here is my thoughts. Slimport has an always on HDCP copy protection. I believe most of the converters/adapters cannot work with protected content, as you could copy the movie with a recording. Try finding an adapter that states it is HDCP compatible. The only one I can find through Google is HD Fury. Good luck.

Hi,

I have a weird behaviour after the slim port is removed from my N4 with Purity/hellsCore kernel.

it's the second or third time the phone shuts down in my pocket and didn't start, only after plugging it to charger.

The battery was over 90% and the slimPort was connected with the charger.
[Nexus 4 Accessories] farmerbb:
Happens often to me as well, with franco.Kernel. Sleep of death issue after unplugging the adapter from the phone.

I don't think it's a kernel problem. I will try to use the SlimPort as little as possible until i'll see what the problem is.

Nexus 5 SlimPort thread

Is there a Nexus 5 SlimPort thread like this one?

I'm interested in the following for the Nexus 5:

What DisplayPort standard does the Nexus 5 support (when using a SlimPort adapter)?

DisplayPort has a USB channel, I know I can't use the micro USB port of the Nexus 5 when SlimPort is in use but can I have USB devices working over the DisplayPort USB channel (and would Android 4.4.4 support this)?

I know we can use a BlueTooth keyboard and Mouse but some workplaces forbid wireless keyboards
[Nexus 4 Accessories] farmerbb:
SlimPort uses the Mobility DisplayPort (MyDP) standard. (EDIT: Looks like the ANX7808, the SlimPort transmitter inside the Nexus 4/5/7, is DisplayPort 1.2 compliant)

SlimPort does not currently support using the USB data pins at the same time as video output, so a USB-OTG mouse and keyboard would be out of the question.
[Nexus 4 Accessories] AusMatt:
farmerbb,

You misunderstand my question re: USB.

I know that SlimPort re-purposes the USB pins of the micro USB connector on the phone such that the USB port cannot be used while the SlimPort adapter is in use.

I'm talking about the USB channel that is part of the DisplayPort standard (i.e. USB over DisplayPort).

If you check the Wikipedia page on DisplayPort (http://en.wikipedia.org/wiki/DisplayPort) you can read about this.

The section of the Wikipedia page on SlimPort (aka Mobility DisplayPort aka MyDP) does not exclude the USB channel so I'm assuming that it's still possible to carry USB over SlimPort.

This leaves open the possibility of either a dock type unit with USB ports or a DisplayPort monitor that has USB ports that will be presented to the Nexus 5.

I'm wondering if Android 4.4+ on the Nexus 5 would support this and whether anyone has tried out such functionality.

My point of view on this topic is being able to use SlimPort enabled devices (such as my Nexus 5) as the sole computer for business purposes ala Bring Your Own Device (BYOD) but with a mobile phone.

Given that phones (such as the Nexus 5) are pretty powerful devices these days and that many applications in the work place are now web apps, it would be very useful if the mobile phone could replace the PC.

The wireless keyboard is the only issue that some business users would not like, hence my interest in this topic.

Thanks for the information that the ANX7808 inside the Nexus 4/5/7 (2013 edition) is DisplayPort 1.2 compliant.

This makes those devices even more exciting for business desktop use as they may be able to support multiple daisy chained DisplayPort monitors through the use of Multi-Stream Transport (MST).

Of course Android would need to support this too.

Regards,

Matt
[Nexus 4 Accessories] farmerbb:
The MyDP standard appears to support USB over DisplayPort: "The MyDP interface also includes a robust 1Mbps sideband channel that provides enough bandwidth to support accessory functions including multi-touch, keyboard, mouse, and remote control of the external display." The ANX7808 also appears to support "Single Wire (C-WIRE) sideband communication".

I'm not sure if anyone's had success with USB over DisplayPort and the current generation of SlimPort hardware though, and I highly doubt that stock Android 4.4+ supports it anyway (maybe with some kernel and framework modifications)

Keep in mind also that SlimPort adapters convert the output to either HDMI or VGA, so I think you would need a direct SlimPort to DisplayPort adapter or cable before USB over DisplayPort becomes a consideration (as far as I know, no such adapter or cable has been produced yet)

Hi,

any suggestion about what adapter should I buy in Europe as of today? (Euro shop or any international shop shipping worldwide)

I've read through this discussion and it seems that Analogix adapter works well while no adapters frequently don't. I'm willing to spend what is needed to get a proper Analogix but cannot find it in Italian eshops (including amazon and eBay).

Do I really need to use a mail forwarding service and buy from US amazon?

Yes, SlimPort works with HDMI-to-DVI cables, as HDMI is backwards compatible with DVI. It's video only, if you want audio you'll need to plug something into the 3.5mm jack.

How can you tell how many fps it can do?

[Nexus 4 Accessories] 3dawg:
The FPS issues mentioned earlier don't bother you?

Incase you missed it, this slimport adaptor doesn't seem to be outputting 1080p@60fps but rather 30fps on both the phone and monitor.

Download fps2d and let it run and average out. That should give you an indication of the fps. You should also be able to tell just by looking at the smoothness of the animations when scrolling or using the phone. It will seem laggy compared to usual.

I trust AnandTech a lot... they know their stuff. With that said I doubt the guy on XDA that experienced low fps was making it up. Maybe there are differences between initial production units and the one AnandTech got their hands on.

FWIW, initial reviewer for it on Amazon who'd also at first observed that it does not fit with the stock bumper, also included the following Update:

"Update: I took sandpaper to the edges of the slimport adapter and it fits with the stock bumper on no problems. Just a tip if you want to go that route."

So sounds like the adapter just needs a gentle sandpaper rubdown. ;)

Not that this is such a useful detail for most of us, as it seems like there is little chance of seeing the official bumper in stock for purchase for weeks, if indeed in our lifetimes. Boy oh boy are Google bad at selling hardware.

I've been having a play this morning.

Using the fps2d app I get 58fps (3-4 runs not connected to slimport)

While plugged into the slimport I get anywhere between 44 and 52fps averaging at 47 i'd say (multiple runs)

So with this I am seeing a definite drop in frame rate.

Another thing I have found is that it plays some videos better than others. Mp4's it seems to handle no problem with virtually no difference in frame rate when playing with HW or SW decoding. Some avi's drop frame rate when playing with HW decoding and some play with no difference. All avi's play with virtually no drop in frame rate will using SW decoding.

In conclusion while using SW decoding all videos play with virtually no drop in frame rate whether connected via slimport or not. Some avi's drop frame rate with HW decoding and a slimport connection makes this worse. All Mp4's seem to play fine with no difference while connected via slimport.

I am going to test some mkv's this afternoon and report back.
[Nexus 4 Accessories] 3dawg:
I appreciate the information! HW decoder frame drops are a little disconcerting, since battery drains much more in SW mode :/
