So basically when I enable HDMI out to my 2560x1440 screen (u2711), the motorola logo displays just fine, but when I select a mode like gallery or mirror, the whole HDMI screen starts flickering and showing portions of the screen every couple of seconds.
The phone itself works just fine, and HDMI out with the same cable works fine on my HD ready TV. The HDMI port on my u2711 is fine as well, at least it works with my xbox 360 in 1080P without error.
The odd thing is, as soon as I enable Picture by Picture on my screen, the phone displays just fine on it's half of the screen, albeit in 640x480.
Is this a known bug, or does anyone have any suggestions on fixing it? Do I have to disable DDC/CI? My cable has ethernet capabilities, so the high res shouldn't be the problem, right? Or did I just buy a ****ty/faulty cable.
I don't think the phone is capable of rendering at a resolution that high, the gallery is in 3D-mode and it's probably running out of Vram..
Maybe force it to 1080p somehow?
I never got the HDMI cable working from my pc high end gfx card to my dell u3011 . Never tried from my Razr but I guess the same applies to it.
Only dual DVI and DisplayPort worked.
Without checking I think the highest res possible on hdmi is 1200p ?
I would always try a different cable before giving up. 9/10 times when I have seen flickering on an HD display it has been a crap/faulty cable, and I have seen it a lot as until recently I was Digital TV installer. Used to carry loads of spare cables in the van as it used to happen so often. You don't have to spend loads on a cable but the very cheapest are usually best steered clear of unless you're lucky. I'd usually go for a £10-£15 cable (15-20 EUR) and not a cheap ebay one.
Thanks for your advice guys!
The max res for 1.4 is 4096×2160, and for 1.3 it's 2560x1600, so my resolution should be fine I think.
I paid ~20 euros for the cable, it's brandless, but from a well known cable retailer here. I don't have any others to test, and compatibility with my u2711 isn't vital to me, so I'm not going to buy another cable, but I still think it's odd that it doesn't work.
I will report back if I find another cable and it makes a difference!

Hi Guys,
sorry for another thread about MHL, but I think this should be visible. I got MHL adapter directly from Samsung (borrowed for testing) and here are some troubles:
1) TV is showing that source is 1080p, but real picture is not that good. Maybe it is worse than 720p.
2) You cannot use the original Samsung MHL without charger in it. Simply the screen shows "no signal".
3) Bigger problem is the fact, that SGS II is discharging while on MHL, even the system is showing charging indicator. It is really weird and I will try to contact Samsung for some details.
Before I will send that email, can anyone check it? In my test it is enough to run some 1080p trailer at highest brightness for about minute or two. After that you will loose 1% from capacity.

What ROM you running?
On earlier ROMs, whilst playing Order & Chaos on charge, my phone would still lose battery.
My setup:
Android version: 2.3.3
Baseband version I9100BUKE1
Build number:GINGERBREAD.BUKE5
According to Kies, this is the latest version available.
interesting, what are you powering it with?, psu adapter into a plug socket or are you just using a usb port to power it, if you are using a USB port to power it then it may not be pumping enough amps.
In regard to the poor picture, The MHL is just HDMI digital and so it cannot effect the picture really, I suspect your player on the phone is doing something to it, alternatively does your TV have compression on that input channel to soften or deblock? - are you sure the video you are playing is full HD or just looks like full HD on your small sg2 screen?
Its a bit worrying if it still drains as this effectively defeats the object of it.
I'm using original charger, which is in the pack. I'm going to test it on second Galaxy S II today and see the result.
With the resolution - I've made the tests on Philips Cinema 21:9 (2560x1080) and even the menu is really awful. Photos taken by the SGS II are slightly blur and text in browser hard to read . The trailers are also bad, as I said above.
I used PC with that TV and same trailer is absolutely smooth, so problem maybe in the player on SGSII, but I bet on problem somewhere in MHL transfer.

I don't think it matters what charger you use, I have just found out the battery is capped at 0.650amp in the kernel....

The 650 mA limit is in effect when it's connected to an AC charger, as determined by the resistance across the two data pins on the microUSB connector. Low resistance (< 200 ohm) indicates an AC charger; if the resistance is higher, it will treat the connection as a standard USB, in which case the current is limited to 450 mA (just below the 500 mA minimum +5VDC current in the USB 2.0 spec). Speculation is that the 650 mA limit is in place to keep the battery from overheating/exploding during charging.
What's almost certainly happening is that the SGS2's charge logic considers the MHL adapter connection to be a regular USB connection, thus limiting the charge current to 450 mA. If the SGS2 is drawing more than 450 mA as a result of its exertions (such as playing HD video), the battery will discharge.
There's probably a reason why Samsung did it this way -- the AC charger also has to power the MHL adapter, which has a bridge chip & support logic on it. If the SGS2 tried to draw a full 650 mA from it, the charger might not have enough capacity left to power the MHL logic.
The power issue has been covered now so it just leaves the output quality. So what you are saying is that you have played the same trailor on the TV using both a PC and your Phone and the phone output is bad?.
Any chance you could take some photos so we can see, I ask as HDMI is digital, you don't really get interference like old scart or S video adapters, usually the picture is either there and sharp or not there at all. If it is blurred it is either the player applying some sort of de-blocking / compression or the TV is, just cannot see this being the adapter.
The SGSII outputs in 1080i. Set your TV to 1080i instead of forcing it to 1080p and the image quality should improve. On mine, menus look crisp and games all work fine. The TV shows that it is 1080i, and I have set mine to accept all settings (720i, 720p, 1080i, 1080p)
So I got the HDMI cable from electroniccrap.com. I have a 720p TV and I only get a blank screen with no sound when I connect my gtab to the TV. However, I do know the gtab is detecting the HDMI cable because the sound from the gtab goes out when the cable is plugged in. I suspect the TV is not capable of handling 1080p signals. Is there a way to downgrade the signal to 720p ?
Sounds silly but wiggle your cable, i thought mine wasn't working but the cable for some reason just needed a little nudge and it started displaying the video.
Known Issue
It is a known issue that SOME 720p TV's won't accept the signal. I have a 50, 42, and 32 inch samsung lcds and plasmas, all work except the 32" lcd.

No, Tegra2s are set in hardware to output 1080p (unless you want to buy additonal hardware like a scan rate converter...(costly)
HAve you tried it on another TV, or tried anpther 1080p input to your TV?
I took the advice from one of the posts above and wiggled the cable here and there. I must have tried for at least 3 hours. Guess what? The cable works only when I hold it at a certain angle , pulled upwards and to the right. I immediately lose the image when I let go.
I sent the cable back for a replacement.

I did a search here. I have the Prime and had great success from 12/28/11 until ICS update around 01/10/12 but since then my TV shows no signal and this lasts for several minutes so the TV has had time to communicate with the tablet.
1. I have done a Factory Reset
2. I have tried all 4 HDMI ports on the TV
3. I have tried a second TV
4. I have ordered and tried a second cable (stranger things have happened)
5. I have called Asus Customer Support
My options are of course RMA but that means no tablet for 10-14 business days or wait to see if and when an ICS update may correct this issue for me.
Am I just out of luck here and just need to give up my Prime for 2-3 weeks or do you think that an ICS update maybe on the horizon and may correct my issue?
I don't think it is an ICS issue. My conection between the prime and the tv works perfectly. BUT it does seem to take about 15 seconds before anything shoes up on the tv after I plug the cable into the prime.

Thanks for your reply. I just went back and edited my post to add that I leave it plugged in for longer than a couple of minutes. I even flip between HDMI channels using the TV remote while the Prime is plugged in. The TV just never sees it!

Did you double check with another HDMI cable? Some cables of lower quality do prevent the Prime and the TV from synchronizing.
I paid $39 for Rocketfish 8' micro HDMI cable from Best Buy yesterday and attached it to the available HDMI port on the back of my 25" I-Inc monitor. My Transformer Prime didn't see that I had the HDMI cable connected until after I shut it down and restarted it, only after doing that the bootup screen appeared on my monitor and Prime and when I logged in the Prime had the HDMI logo displayed on the tray.
The problem I'm experiencing now is stability. I get constant screen flickering from the monitor when I'm viewing the Prime through the HDMI connection. It seems like its software. I have no other devices to test this out on besides my monitor as the HDMI on my HDTV is only capable of receiving 1080i.
Another sign that it seems like software that's causing the flickering is that I notice considerable lag from the mousepad cursor using the Dock when my monitor is flickering from viewing the Prime over HDMI.

I haven't noticed any flickering but I have only watched real steel ones mine so far. Was a 1080p mkv file and I hooked it up through my receiver. The tv is 46" so I think I would have noticed. Have you tried other files? Oh, and I use a 6' cable is bought from monoprice for like $5

I get screen flickering (or better description screen blinking) immediately after connecting HDMI to it.
I can be just viewing the Prime's desktop not playing back any video and my Monitor displaying the Prime over HDMI will blink by going complete dark and it will continue to do this randomly and frequently.
When playing back video it continues to do this and not only is it losing the picture it's also losing audio in this screen blinking problem.
---------- Post added at 05:39 AM ---------- Previous post was at 05:10 AM ----------
I just tried the HDMI input on my BenQ monitor and I get a stable connection, no blinking.
Only difference is that my BenQ monitor has no built-in speakers and it's not a 1080p monitor it's a 1680x1050 res monitor. So I'm getting an improper viewing aspect ratio.
Is there a way to turn off the audio from outputing through HDMI and keep it coming from the Prime?
Turns out my TFP works fine connected to my old Samsung 30" HDTV CRT over HDMI, I didn't try it at first because I thought the the TFP would try to output 1080p to the set which can only handle 1080i.
I'm surprised that it connected instantly to my HDTV, now I need to correct my TV's left and right fields in the service menu as it is zoomed too far in.
Does anyone know if the TFP have a 16:9 or 16:10 aspect ratio? I'll have to keep this in mind when adjusting the settings cause I want to maintain a 16:9 setting on the HDTV.

Yes sir in my original post I state that I bought a 2nd cable. Also since it was working fine before ICS and with all the things I have tried in my post it is either ICS or the port on my Prime. Or yeah somehow I got 2 faulty cables and 1 of them worked great until the update!
No I just hope it is ICS for me.

Thanks, I tried shutting the Prime down and restarting while the HDMI cable was plugged into the TV but no dice for me.
My HDMI was working and I have watched several movies on my TV previously.
Fast forward a few weeks and HDMI no longer works! I bought a cheap cable on Amazon, and noticed the micro connection was very loose. The HDMI notification no longer shows up. I ordered a 'real' cable from mono price, but still no luck.
No picture and no HDMI notification - arrgh.
The TP HDMI connection seems very loose, even with the new cable. Looks like an RMA for me.

That's what I'm thinking too. It's not real loose but it does have wiggle room that I didn't notice before! I hate it because I'll be without it for 2-3 weeks and everything else with the tablet works great!
I have tried HDMI out on 3 TVs and it only works on one. The one it works on is the newest one by a few years.
On the other TVs the results range depending oddly on the cable. A $30 Rocketfish cable I purchased for testing and now returned resulted in zero output on the other two TVs. My cheap cable will make some crackling noises and the screen will flicker on and off.
No output at all through my my receiver.
On the third TV... a 2012 model I believe, it works great. I have never had any issues with HDMI out on the other TVs although I only use an older laptop and a PS3.
Any clue what might be going on? Do I have a bad device or are my older TVs not compatible for some reason with the Tegra 3 HDMI out?
Thanks.
I finally got through to Hisense support. Major PITA as they disconnect you after a minute or so of hold time. Not like I expected anything different. Regardless they guy had no idea about any issues.
I'm going to go and buy another from Walmart and see if it has the same issue or not.
Went and bought another one to test the HDMI out with.
Same issue. So this tablet has problems with some TVs. Searching a bit further it seems like some android devices regardless of manufacturer have HDMI out compatibility issues.
Chromecast should hopefully solve this issue anyways.

I've seen some strangeness of a different type. When I plug my Sero 7 Pro in to one of my TVs with a particular cable, the touch screen starts acting funny, meaning a touch registers as a swipe and we'd things like that. Anyone else seeing weirdness like that?

HDMI issue
I am having an HDMI issue. For me, whenever I connect an HDMI cable to any HDTV and use Adobe PDF Reader while scrolling and zooming in I get all kinds of artifacts and glitches on the tv screen but not the screen of the tablet. I've used two different tvs and they both react in the same way. These jagged lines appear on the screen while zooming and scrolling but disappear right after i lift my finger off the digitizer. I haven't tried many other apps but it seems like its solely Adobe PDF Reader reacting this way. The few other apps I've tried do not react this way.
Would this be caused by...
The tablet itself?
The current software/os version?
The hdmi cable?
The tvs?
Model number: M470BSA
Android version: 4.2.1
Kernel version: 3.1.10
Build version: P756.6.02.11.00
I just bought the tablet a couple days ago and was notified of an update, P756.6.02.20.00. Should i go ahead and apply this update? or has anyone experienced this issue before and found a remedy? Any help regarding this minor but annoying issue would be greatly appreciated.
Different cables with less or more quality is not odd at all really.
I would not be surprised to find out that all your problems are from the cable you used and/or the tv you tried to use and not the tablet.

There are definitely issues with the Sero 7 Pro and older TV's via HDMI out. In my case, I'm lucky enough to get a picture on the screen, however it fails back down to 480p which is just unacceptable.
With that said, there is some hope. The issues that I am experiencing do not seem to be directly tied to a hardware problem, but rather software. Via rooting and trying a custom rom, that is not based off the stock rom, I was able to get a 720p picture on screen though there are other issues

The touchscreen being erratic happens on a few of my other older devices with HDMI & MHL connected too. It seems that most of these haven't been tested extensively in this mode. There's a ground connection problem, I remember it was better if I connect a charging cable also, or holding it slightly differently or setting it down when using the touchscreen & HDMI connected.
Erratic screen problems
I almost returned my tablet today. I have three of them and only one exhibited erratic behavior while using HDMI out.
The screen would barely respond to my touches. It would misread and select the wrong things. I couldn't play games or scroll the screens. A mouse would work but not touching the screen.
It turns out the erratic screen problem goes away if I turn off the Sony Playstation 3.
This time I tested it and it is repeatable. I had both the cables plugged into the TV next to each other so now I separated them.
Now that I think of it I remember seeing a video about a guy who thought he had screen problems but it was interference from a nearby computer.
I found the video I remembered of the guy who was having the same problem due to interference from his computer. He demonstrates the erratic screen behavior and says he returned his tablet twice thinking it was faulty.
I can't post the link...oh well. You'll have to look it up.
Hi. Has anyone tried using a USB C-to-HDMI cable to connect Mate 10 to a monitor. How do you like it? Do apps scale well on monitor? Assuming you hooked up a bluetooth keyboard and mouse, have you tried editing a document? Thanks!
still waiting for my Mate 10! But one of the reasons for getting one is USB-C to HDMI. One thing I noted when sourcing a cable - if you use a "standard" cable you won't be able to stream Netflix/Amazon streaming due to lack of "HDCP" compliance. I got a cable that was compliant for a few euro more on Amazon. Just keep this in mind if you want to stream Netflix etc.
Does anyone know if this would work with a Surface Pro 4? The SP4 has a mini display port, so maybe with a mini display port adapter, we can connect Mate 10 to the SP4 and view desktop mode on the tablet. Would that work?

Well the cable I have purchased is the one linked below - which the manufacturer says (elsewhere) is the HDCP compliant one. I can't guarantee you that it will work though!
I am expecting my phone and this cable this week so will try out!

NOTE - this manufacturer also sells usb-c to hdmi cables that it says are NOT compliant. Only one above is one they say is compliant.

Thanks I'll look for it here in Amazon US, no problem returning so might as well try.
I tried it out briefly when I got the phone.
I used a type c to HDMI adapter, with a normal HDMI cable.
Some things I noticed:
I think this drained the battery more than anything else I've done with the phone (including gaming).
The phone was noticeable warm after the session.
My phone rebooted shortly after the desktop session. Like it crashed.
The phone states it's in reverse charge mode, like juice is also bring drained from the phone to the TV.
I couldn't get YouTube to work full screen without borders. Unless I was mirroring the phone screen (which means phone screen also remains on).
I've mixed feelings, it's early days I guess.
Ok, I am still waiting for the cable from Amazon but ended up purchasing an adaptor from Maplin.
Worked fine - as in outputted screen of phone (in phone or 'desktop' mode).
But I did notice that the screen resolution as outputted was far less than the resolution of the screen - I would have expected the 1080p display to mirror across to the TV.
It wasn't that it was bad, just blurry text and not crisp when looking at video. Whereas in the past, with a phone with an actual hdmi connection as opposed to usb-c, or indeed when outputting a media player with hdmi or casting using chromecast, the quality is perfect.
Perhaps I'm doing something wrong or perhaps the Maplin cable is not up to speed. Open to ideas.

I think this drained the battery more than anything else I've done with the phone (including gaming).
The phone was noticeable warm after the session.
My phone rebooted shortly after the desktop session. Like it crashed.
The phone states it's in reverse charge mode, like juice is also bring drained from the phone to the TV.
I couldn't get YouTube to work full screen without borders. Unless I was mirroring the phone screen (which means phone screen also remains on).
I've mixed feelings, it's early days I guess.

I was wondering about the battery drainage. Some cables I've seen have an additional input for charger. Maybe that might help

Interesting. Sounds like you are using Mate 10 Pro. Wonder if resolution is improved using Mate 10.

No, normal Mate 10.
Other cable arrived and same situation. To clarify, it's fine, and perfectly watchable, just not crystal clear. It strikes me that this method seems like the usb-c to hdmi cable is simply mirroring the display of the phone rather than actually outputting the video file itself independently - as would happen with a HDMI connection as you used to get on some phones. Perhaps this is something to do with the issue.

......hope you post result of amazon cable! have a nice day!
It was amazon cable I referred to above. So same with maplin adaptor and amazon cable. Tried outputting a HD YouTube video but not much different. As I say, fine, but not as clear as would expect if you copied that file to a media player attached to a tv via hdmi
Hooked mine up with the Huawei supercharger and cable and it slowly drains the battery in desktop mode. Without charger it will suck down the battery fast. Benched with Antutu and got 175k on phone. In desktop on 30" monitor got 157k. Still faster than my Mate 9. My S8+ in Dex was just about worthless. Also with the M10 in desktop with wired mouse has zero lag. Bluetooth mouse a different story. So gaming is pretty good on a monitor.
Ok, I "solved" my problem by fluke. I would love if someone more techy than me could explain but this is what I did to fix the fact that the HDMI output looked more like 640x480 than a hi def picture.
Went to TV settings, and selected advanced, HDMI settings, and Changed HDMI "Auto" mode to HDMI Graphic mode (choice of Graphic/Video - video was default and was crap). As soon as I did this I had perfect outputted photos and videos.
According to one tv manual I found on a search:
"Graphic: HDMI input timing set to Graphic mode (PC) - The image is full scan.
Video: HDMI input timing set to Video mode. The image is over scan."
According to someone on a completely unrelated PS4 forum:
"Basically by changing the HDMI mode to graphic, the HDMI output (be it gaming console, pc, or cable) bypasses "extra" processing features of the TV that
make the game and TV broadcasts look crappy and also causes lag. By bypassing those features you will get a much clearer picture."
Either way, it's fixed. On my tv. And on a shop tv the same issue. So given that I've connected previous phones with hdmi connections a few years ago without issues, this suggests that it is something to do with how the Mate 10 outputs signals in a way that TV recognises?
Love to hear an explanation from the experts. Thanks.
Edit: someone else with a similar issue on another device - so it seems the issue is that the Mate 10 is not recognised by most Televisions as a "PC" which would correct hdmi mode to "graphics" ?
"When I switch between the Blu-Ray and the PC on two separate HDMI inputs, the TV doesn't detect that's it's connected to a PC, so it doesn't switch from video to graphics mode - which is required for it to look good as a computer monitor.
Since the TV deosn't recognize the PC and auto switch to graphics mode, when I switch from Blu-Ray to PC, I have to dig down into the menu and switch the HDMI mode to graphics manually - and then back when I go to the Blu-Ray. -- Major pain if I'm switching back and forth."
Any ideas? Is this something Huawei could fix in firmware?

It looks like its related to the TV resolution : I have the same issue (640*480 resolution) when I connect the mate 10 pro to a 4K native TV but it works perfect when connected to a full HD TV !! It's a shame as 4K tend to be the standard display, so I guess Huawei should fix it whith a firmware update. Any other solution (HDMI 2.0 cable maybe??) ?
