I just got a USB to HDMI cable, or can be called a MHL cable for my SGSII, but the output resolution was only 720*480(not 800*480, not 1080P, not 1080i) after the phone had been connected to the LCD screen(the screen reported this information).
I tried to set the monitor to "Full Screen" mode, but it just upscaled the image, the resolution still remained at 720*480.
Anyone has any idea about this problem?
BTW, I'm using the SiyahKernel with the stock ZSKI3 ROM.
Thanks!!
Open up the video player, it outputs at max resolution.
It does this because the system UI is running at a low resolution, so it can't output higher.
Like you I was under the distinct impression when I purchased my GS2 that the phone would output 1080p through MHL. Sadly this has not been the case. I was wondering if I was forgetting some setting but based on this thread it appears I'm not.
Wouldn't have been a deal breaker but it's still too bad.

Let's be clear.
The phone DOES output 1080p through the onboard video player. Open up a 1080p video and try it out.
Using the Samsung MHL adapter, I can do 1080i to my 32" Vizio (the only HDMI monitor I have access to). I see this resolution even when not running the video player; i.e. on the main "desktop" and app drawer screens. Of course, that's upscaled, but it still looks pretty good.
The Vizio supports 1080p, but for whatever reason, the MHL adapter won't provide it. I haven't spent a lot of time on this, but maybe I'll take another look at it over the weekend.

I did try the 1080P video playback as soon as I got the MHL, but like I said, the resolotion which the LCD screen reported is only 720*480, no matter in what kind of UI or application.
I had a LG Optimus 2x few months ago, and the HDMI on it worked perfectly with the same LCD screen.
Actually i noticed some interesting things when playing with the MHL. As i got a Samsung P2770HD screen i got basically all the connections. When i plug the phone directly by the HDMI plug screen reports full HD resolution (upscalled ofc, wondering if changing lcd density could give this some smoothness), but when i plug it trough the same cable but with a HDMI-DVI converter on the end the screen reports a lower resolution, phones native one if i remember correctly (which looks actually smooth and not pixelated, but i think there were all the fancy monitor's software enhancements on).

I've got a feeling you got this instead. www.ebay.com.au/itm/3-FT-Generic-Hi...AU_MobilePhoneAccessories&hash=item2567cc3a59
Excuse me, but at a first glance i dont think such cable could give any output at all, from what i understand of the mhl protocol the signal is different (quoting wikipedia "Other than the connectors being used, no USB nor HDMI technology is being used. It is exclusively MHL signalling through the connectors and over the cable. Other proprietary and custom connections are also allowed."). Fortunately we got an easy way to know, Thread starter, does your cable have also the power connection? And do you use it?
I wonder in the Note outputs at 720p?

I see the HDMI output quality very poor
I believe it has to be related to software or cable/monitor hardware, because my stuff gives me full hd resolution. Maybe compatibility issues, as we are using mhl adapters?

what rom are you use ?
Stock, Kies supplied ki4 CF-rooted. Nothing fancy as u can see. Also my screen is a samsung P2770HD, which might be helping. As I posted a page before, I get low resolution when connecting to DVI trough an adaptor.

I use stock KI3 and you should test on some larger LCD 40-46"
When I finally get my hdmi - dvi - d-sub converter i'll try to use
Some of the projectors in the university, that might give interesting results. Anyone tried to use better lcd density values to compensate for the upscalling?

did you sort this as ive got the same but im using a hdmi to dvi adaptor to try on a monitor, it says 1280 x 720 support on the box...
cheers
I'm experiencing some sort of overscan when using the adapter, but I'm not sure if it is the phone, my av-receiver or the TV.
Oh well. It was dirt cheap on dealextreme.com. Not like I lost a lot of money
I haven't got one yet but have been researching like crazy. What I have found so far is that cheap ones are cheap. They do what yours is doing, the connections need to be wiggled to keep it connected etc. Spring for a good quality one if you're actually going to be using it. The folks at MHL have a good one I think, just haven't been able to find it.
No 1080p when using DVI
What a pity! Back in time, when we had ICS there we at least got the possibility to use 1280x720 (as far as I remember) when using a monitor via mhl->hdmi->dvi chain, now we are only getting 640x480, Even when watching movies.
You will only get full HD whenn you connect directly usb-.hdmi->TV
So no desktop mode any more.

I don't know how helpful this is, but Samsung actually makes an HDMI media dock for the GNex that works really well. I'm not sure how much it costs, however, as mine came with my phone.
The only issue I've had with it is that I have to take the case off my phone to use it.
The real good question...
The real question here is: "Can the Galaxy Nexus output 1080p playback, given his native resolution IS NOT 1080p?"
I mean, I know that OSs can adapt second displays and all that, Linux does that, but can Android do that? Treat the HDMI output as a second and independent display? I hope it can. I have a MHL=>HDMI cable (that also needs the power adapter to be plugged in) and I can only get 720p out of it, and the GNex can actually play 1080p movies, so... That would be awesome to play 1080p movies on my TV screen.
Hi Guys,
I have the one x, Optoma pk301, MHL adapter and the required HDMI cable. Got the connection all set up but I'm unable to get a display on the projector. Are there any settings in the phone that i have to change/switch on to display on an external screen?
Thanks
Mine worked right out of the box. I used a Galaxy SII adapter. As soon as i connected HDMI, charger and phone, it switched to landscape mode and the picture showed up on the tv.
As far as i am aware, there are no settings on the phone to enable/disable MHL.
Did you plug the USB to charge ? It says no power > no video
Im using this one:
http://www.amazon.com/Samsung-Smart-Adapter-Galaxy-Mobile/dp/B005MR82GA
Its working now. Was displaying a red X before. Didn't do anything other than just unplug and re plug everything
Can you tell me if I play movie on my TV by mhl cable, does it shows external subtitles (.srt)? And, can hox play movie on TV with phone screen of during.

"Micro USB to HDMI® MHL Adapter - Black" - quick review
I just received the MHL adapter from MonoPrice, about $10 US:
http://www.monoprice.com/products/p...=10833&cs_id=1083314&p_id=8805&seq=1&format=2
The product description implies some phones can power the MHL adapter, with the One X you must supply power via a micro-USB charger. Be forewarned, the load may be a little higher than what some phone chargers can deliver; my EVO 4G charger would shut off after about 10 seconds, an old Nexus One charger worked fine.
Output is 1280x720 60Hz (should auto-adjust to the TV, don't have a PAL display here to confirm this). The Samsung HDTV was set to "Just Scan", meaning no scaling is done by the TV.
The resultant HDTV image is underscanned by about 35 pixels on each side, 20 pixels on top and bottom, resulting in a display area of 1210x680. I think this is a problem with the One X GPU drivers, and not the adapter because I doubt a simple device like this can do any scaling. At CES, I played with a few Transformer Primes running Shadowgun Multiplayer, mirrored to HDTVs at 1280x720, and there was no underscan, so this is likely not be a limitation of Tegra 3 GPU.
I got the red X once (displayed on the TV), afterwards it would not mirror the display to the TV until reset, so the connection handshaking is kinda finicky. I've been plugging the micro-USB power last, after the phone and the HDMI is connected and the phone is powered on. Sense should flip into landscape immediately, if not, something is wrong. If you power on after everything is connected, you should see the lock screen in portrait for a couple seconds, then it'll rotate. Sense works surprisingly well in landscape, I'm surprised that HTC didn't allow this mode without an MHL adapter connected.
There is a slight performance hit on the One X when display mirroring is active:
GLBenchmark 2.1.4, native display:
Egypt Standard: 48 fps
Pro Standard: 54
GLBenchmark 2.1.4, HDMI mirrored:
Egypt Standard: 42 fps
Pro Standard: 52 fps
If you want to demo a One X, play Shadowgun THD on a HDTV, it looks absolutely amazing. You are "playing blind" on a touchscreen, but once you get a feel for turning and shooting (right thumb), it's pretty easy. Ideally, this setup is screaming for a game controller, but I haven't come across a thread about this yet for the One X. Support for analog sticks has been in the OS since 3.1, so the keymapping utilities on the Market shouldn't be necessary, but I need to look into this further.
Note: the images were taken of the HDTV using a point-and-shoot and scaled to 720p, so you can see the degree of underscan (the unfiltered decimation is very visible in the fonts).

The TV is full HD, the phone passes 720p through the adapter, looks like it's a direct mirror.

Everything you see on the phone is mirrored on the TV. If you are watching a movie with subtitles on the phone, you will obviously see them on the TV.
My best experience so far watching 720p & 1080p has been with MX Player, but a lot of people also use Dice and Mobo.
That was not the case with my sgs and tv out and as far as I know with sgs2 tv out via mhl. It's mirroring everything but subtitles.
hi i have two days htc one x and have two hdmi cable to tv but same result no signal what i do wrong i use this one please helpme
I bought a MHL adapter from Mobilefun and I get the phone picture on a my PC monitor, with a little pixel loss as described by rasterX.
However I tried looking at a video I recorded with the HOX. I played the recording using the stock player and MX player.
In both cases, the playback is too fast on HDMI, it's like pushing a fast forward button.
With MX player I tried the different options (hardware/software): hardware is too fast, software is variable: complex pictures are too slow to display, less complex pictures are shown faster but since the display time changes according to the picture, the software playback is useless.
I tried two different PC monitors, one is Philips with a DVI-HDMI adapter, the other a DELL with a direct HDMI input, results are the same for both. I'm in a 50Hz country (France) if ever this can have a side effect...
Anyone has similar issues with MHL?
I tried my Samsung MHL adapter and it worked. My TV resolution is 1366x768.
When I connect all cables (inclusing power of course) I get portrait screen on my TV. As soon as I play movie or game, it goes landscape. When back to homescreen, it's portrait. No issues in Diceplayer or MX Player. Worked in HW and Software. Software mode allows to see subtitles on TV.
Sound only out of one channel
I only seem to be getting audio out of the left channel. I've tried 2 MHL adapters, and 2 different HDMI cables with 2 different TVs.
What's going on!?

I'm having the same problem, only left channel is working on TV over mhl adapter and if I plug headphones in one x 3.5 mm jack it is OK. I tried BS PLAYER and MX PLAYER.
Same symptom here!
hmm ... bug?
I'm trying to hook my S3 to my TV setup and am not having much fun with it. With the MHL I am getting stuttering and lagging. I have:
Samsung MHL adapter (from Infuse)
Samsung 11-to-5 pin converter
Samsung 1080p HDTV
BT keyboard & mouse, charger, HDMI, etc.
Stock ROM
The image quality is good for web and photo use but it lags and stutters. For games it makes some games nearly unplayable. I can see the phone's screen and everything is smooth but looking at HDTV I can see a lag maybe 0.5 seconds and much slower update rate, very obvious when you move the mouse. The TV shows [email protected], so it's not 1080p. I've done a LOT of searching online so maybe there's not anything new to say but I guess some people have been able to get [email protected] I guess one thing I didn't find, does ANYONE have smooth/lag-free 1080p with S3 MHL with any adapter?
I wonder if 1080i video plays at true 1080 resolution because I noticed when I play back 1080i videos I've taken with the phone itself the image quality and speed are much better. Maybe that's why Samsung decided on 1080i output rather than 720p? I came across a kernel for HTC One S (which is also a Qualcomm S4) that supposedly forces 720p... is there one for the S3?
Another issue is that audio only comes out HDMI, I want it to come out of headset to plug into AV system. I've seen a lot of people with the problem posting but no solutions? Probably isn't possible...
My third problem I actually found an issue to. That is removing the onscreen keyboard when using bluetooth keyboard and mouse. For that I used the app Null Keyboard: https://play.google.com/store/apps/details?id=com.wparam.nullkeyboard&hl=en

Thought I'd pipe in. I am also trying to figure out if this MHL adapter allows 1080p video as I want to use it for watching movies on a 60" 1080p plasma TV, as I don't want to purchase it if it doesn't and the forums are very confusing on whether it does or doesn't.
I wanted to say about your second problem. If you want to pipe the audio to a stereo/surround sound system, all you have to do is plug the TV audio output into the sound system's audio input. This is how I have my laptop to TV setup currently: laptop HDMI-> TV; TV audio out -> sound system.
Just be aware, some TV"s or sound systems might not have compatible audio connections. For example, in order to hook up my Vizio sound bar to my Panasonic Plasma, I had to use the fiber optic cable.... didn't have audio RCA audio out on my Panasonic.
Thought I would amend my previous statement. I was assuming that you wanted the sound that goes with the TV only... However, if you are just looking to have music on without turning on your TV, you can get a cheap miniplug-to-RCA adapter from Radioshack or the like. Should probably cost around $10 on any given day. I've been doing this with my sound system and portable phone/players for years.
buy a dual/quad core HDMI "thumbstick" for $100.
It'll be better then what you are trying to accomplish
I am experiencing weird bug. Connecting to DVI monitor through adapter direct forces 640x480. Through AV receiver black screen at all, only audio works. I guess my monitor or adapter is the reason, however this setup works well with raspberry pi (1280x1024).
Does anybody using HDMI to DVI adapters to connect Fire Tv? Is there any way to force resolution? Changing through gui is disabled for me.
Sent from my LG-D802 using XDA Free mobile app
I'm having a similar problem. My TV is old and doesn't have an HDMI port, so I'm using an HDMI to DVI adapter as I did with my Pi. My screen goes black right after "Checking for Updates"
This is apparently an HDCP issue, which I don't know much about. My TV's DVI port is supposed to be HDCP compatible. There are "active" adapters that can fool the Fire TV and make it work, apparently, but I'm trying to get it working without having to spend another $30 on another stupid adapter.
It's a very disappointing bug, I guess. When I connecting it through receiver my monitor shows 1280x720 but screen is always black. However rarely I can catch flickering with signal. It means monitor support this (720p) resolution. On direct connection it works, but at 640x480 and not allow to change resolution. I thinking about buying optical audio cable to connect it to receiver directly but it's about 30$ and resolutions is so odd. I hope this will be fixed with new OTA. So if anyone is thinking about to buy Fire TV to use with DVI monitor, right now it looks like a bad idea. I'd rather bought something other if know that.

I got my TOSLINK cable for about $5 (with Prime shipping) from Amazon, and a TOSLINK to stereo RCA converter from eBay for $13.
When you get the black screen, if you unplug the HDMI and plug it back in with the right timing (fairly quickly but not too quickly) you can kind of make it work. It looks like crap but the menus are navigable. The first time, I had colorful static with the clear picture flashing through every 5 seconds or so. I reseated the HDMI cable again a few more times and it came up clear (except for the terrible resolution).
Thank, I will check for cheaper dealer. The price I've talking about is for belkin cable. As for you hack thanks for information may be it will be helpful for someone. Behaviour you describing stopped for me after first OTA. Right now I always get crap resolution on direct connection without flickering. But before update it flickers continuously too. I hope next OTA will fix it. May be drop a line to amazon is make sense?

Finally I've bought a cheap TOSLINK cable, and was really disappointed to find it almost quiet. For an hour trying to switch different modes on Fire TV and AV receiver. My last hope was factory reset and it helps, so, I'm with sound right now it's much better, but still on a crap resolution. I hope Amazon will fit it, I believe hardware is ok.
Sound works for a day and again disappeared. I think for some reason device forced routing it to HDMI. I've just leave it along for a day and after woke up uncovered no sound. However receiver show, that signal is ok, if not it is blinking. But signal is silence. I started to think about selling this piece of crap.
I found some info about this bug. It's a well known android problem.
Some sources mention it was fixed since 3.8 kernel issued.
Current firmware incorporates 3.4. I hope next update will fix this.

Any updates on the situation? I was hoping to temporarily connect my Fire TV to a monitor that also only has DVI input. I do have an HDMI-DVI-cable but it's going to be another two weeks unti the actual Fire TV is released here in Germany.

The last version I've checked was second update which not affects root. And problem still present. However with low resolution it works, I believe this is a kind of safe mode. Currently my monitor is burned out, so no news.

Did anyone manage to work out a solution?
I'm having a similar issue with an hdmi to dvi adapter - works fine if hooking up to a monitor via hdmi, but if using the adapter it only outputs 480p - and says the monitor doesn't support higher resolutions. I'd love to be able to use the AFTV with an older, larger DVI-only monitor that I have.
