Hi guys

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.

[Q] t mobile|s II|2.3.6|TV Out ROM

I need some pointers for a good ROM/kernel which supports TV out for this device.
I am aware of the various uPnp and transcoding apps over wifi which not all the time stream lossless quality. Please suggest me a tested ROM or point me to a thread which lists a good ROM with TV out capabilities for gingerbread 2.3.6.
Appreciate your help.

Yeah, that's the only bad part about this. If you don't have a tv that streams, you have to buy the adapter which ain't cheap.
That's about the only thing I liked on my G2X, that it had a hdmi port.

It can stream through my xbox or ps3 but you need a 3rd party app. I dont really care for DLNA its a great concept but its really choppy when trying to stream a movie from your phone..music and pictures are great tho...

dont underestimate
Darkside was my last hope and it has not failed me. I have been using this ROM starting 2.2a version. TV out definitely works.
Im using the Mx Video player which has capabilities to show subtitles out of the mkvs (most other players dont) which are not attached to the video. Both of these are a good combination. Do you guys know any other better player?
The audio however is a bit downscaled and the 720p is a bit pixelish. (you can see the bigger pixels if you get closer). Both stock player and mxvideo player did this. so im thinking it could be a phone limitation.
Still Darkside was the only ROM I saw for now which has been running stable for TV Outs..
And btw, Darkside just released Darkside 2.4 .http://forum.xda-developers.com/showthread.php?t=1473077

Is this tv out with the headphone jack using a rca cable (yellow, red, and white output)? Can the t989 output video and audio to a tv using such a rca cable through the headphone jack?

MHL problem?

Finally bought the expensive mhl adapter for the s3 and after hooking up my phone to my samsung px2370 1080p monitor, I don't like what I'm seeing. The picture looks really fuzzy and reminds me of interlaced output. Plus my monitor is reporting a resolution of 1920x1079. Anyone experiencing the same problem?

Im thinking its because I'm rooted to be honest, it works by shutting off the device first then plugging everything in then turning it on and it's supposed to pick up from there but nothing happens. The same with my One S.

It might just be my pc monitor. I can't even get it to work with my computer via hdmi (dvi works though, as well as with my 360 and ps3). The adapter looks legit to me. I'll be trying it on a different tv and/monitor in a bit

I bought the new MHL adapter as soon as it was available from Samsung. Output from applications like Netflix is reduced quality, this is intentional by the Netflix app. If you play a HD movie, you will see the quality is very good.
My only problem was lag. It looked good, but it was the equivalent of playing a video game with a framerate of around 20 FPS, it made gaming impossible and movies frustrating. I was told it may be my MHL adapter, but I haven't gotten a new one yet.

Saying it's the adapter is the easy answer. I have one that works perfectly on almost any LCD TV I have tried, but on LCD monitors, I have issues usually. I have used it with an HDMI to DVI cable, and got the exact result you described. I think it has something to do with the monitor not recognizing the native output. I haven't used it on an HDMI monitor.
I can confirm it works quite well on almost all TV's.

Ok I think I know what the problem is now. Seems like the s3 only outputs tp 1080i, that explains the flickering and fuzziness on my Led monitor. Is there no mod or hack to at least make it output at 720p instead (since 1080p would probably be to demanding)? Why would samsung stick to just 1080i? Was it the same with previous phones like the s2?

Now that I'm on the puter it's gonna be easier to explain, I bought a T-Mobile MHL kit when
I got the HTC One S and rooted the device but for some reason it wouldn't work with it so
about a month after I had the One S I bought the GS3 and rooted it (still have both) and
tried it with this one and still nothing.
I was told by a few that it might not work on a rooted device but after doing the research it
seems that I'm the only one having this problem but I figured trying it on a different device
should show something, I'm at the point now that I'm sure it's the MHL kit and not a root
problem.

AFAIK only 1 cable/adapter exists that works with the s3 and its an official samsung product. Previous mhl adapters won't work due to a change in pin layout to the connector so if you bought one that isn't marked for the s3, the most likely isn't compatible and won't work. Even official s2 mhl adapters won't work

It figures, I should just restore the One S to stock or sell it but on another note I just posted a tutorial for anyone interested on how to use the GS3 and the PS3 as a media server, connections and settings if you have a PS3 already. In the T-mobile general section.

mhl to hdmi adapter

Just bought 2 from Mertiline... i'm new here and cannot post link so here's product code #0005278. Price is 9.99 but if you buy 2 you'll get at 8.50 each. They're working good, i've just watch 720p video that i took with my T989D and quality is very nice.

That's cool. Im thinking of getting one too. Didn't know they were so reasonable.
Sent from my SGH-T989D using xda app-developers app

Im using the samsung one..really great quality. was $20.00 @ frys i think?..read somewhere that some third party MHL adapters messed the phone up so i decided to use the factory recommended one:good:

i remember seeing the mertiline deal...was about to jump on it, until i realize it doesn't allow me to plug in the charger. I think I'll be ordering one from monoprince that adds an inline USB charging port. But good to see the video quality is good via the converter.

Quality
How is the quality? I want to use mine to watch youtube and downloaded videos on my TV. Is the quality comparable to connecting my laptop to my tv via hdmi.
Thanks

Sorry for the delay, i could not say is comparable to HDMI with your laptop but it's still very nice to watch. I tried youtube videos, WMV, AVI, and 720P MKV Videos without problem,...You can notice some small blur when there.s a lot of movements in the videos. Maybe the Original Samsung Adapter is better than this one, i don't know i don't have one in my hand to compare...

I ordered an mhl adapter off eBay with inline charger ... but it doesn't seem to work... it charges my phone but I get nothing on my television... :/ I have it on proper input .... is there something I am missing?
Sent from my SAMSUNG-SGH-T989 using xda app-developers app

I've read other threads saying the ones from e-bay it's a hit and miss... some works some don't!!!
Did you try to reboot while it is plugged ?

I bought the cheapest one I could find for like $5 and it works great. The adapter doesn't seem to work with any of the JellyBean roms, just ICS and lower if that helps.

whenever i use my sgs2 with a MHL adapter the phone goes into 'auto rotation out of control mode' when i switch inputs on the target device. i'm sure it has something to do with it losing HDMI sync, but i've never seen a fix for it which is so damn annoying.
other than that it's pretty nifty.

Slimport performance?

I was extremely disappointed in the nexus 10's laggy HDMI out. Anyone know the performance on the nexus 7 now? I hope to play emulators on the television.
I'm hoping for lag under 500ms. Really under 100 preferred.
Sent from my Nexus 7 using xda app-developers app

Good question, although personally I would want lag to be under 30ms for gaming.

Well really as low as possible. But I don't want to be greedy.
If it has good performance, I'll be playing my favorite old SNES games : D

I suggested the lag might be because the slimport adapter (according to reviews) is always sending HDCP (encrypted content) even for content that doesn't need to be copy protected.
I don't know for sure if that is the cause, but HDCP can introduce slight delays depending on the equipment.
Some people claim to use HDFury to strip the HDCP and use VGA input on their displays. I presume they feel HDFury can process HDCP faster than their TV can. However, if the issue is on the nexus or slimport adapter side, then HDFury really wouldn't help because the lag already happened.
I don't know if this is the case, just providing info for you to look into.
I suppose one could buy the VGA slimport adapter and test that theory out as VGA doesn't have HDCP.
BTW does anyone know how the always-on HDCP protection is working on these slimport adapters?
Is it
N7(HDCP1)---->(HDCP1)SlimPort(HDCP2)---->(HDCP2)TV
where HDCP1 and HDCP2 are 2 separate encryption/decryption cycles.
or is it
N7(HDCP1)---->(HDCP1)SlimPort(HDCP1)---->(HDCP1)TV
Where HDCP1 is more of a pass-through across the slimport adapter.
I looked at the specs for the slimport transmitter and receiver chips here:
http://www.analogix.com/pdf/ANX7805_PB.pdf
http://www.analogix.com/pdf/ANX7730_PB.pdf
and it seems both transmitter and receiver have HDCP capabilities, so it seems like the first option is a possibility.

I would like to know which Slimport adapter you are using and also your HDMI cable. I just received my analogical Slimport adapter and there is definitely a lag when playing games. Works fine for viewing videos showing pictures, but I have a logitech revue that I can use for that.
I Tried to play some SNES games and the lag made them almost unplayable. Killer instinct and super Mario world were the games I tried. I really hope it's my HDMI cable, but since it works fine with my PS3, then I think it might be the slimport adapter. If that's the case, it really sucks that I wasted $30.

So it appears the TV you use plays a factor. I was originally testing the Slimport adapter with my 32 Inch Phillips LCD TV, model # 32PFL3504D/F7. I went to my bed room and plugged it into my Walmart brand 26 inch ILO TV and to my surprise, I was a able to initiate combos on Killer Instinct with no lag at all.
Not only was it an older seemingly lower grade TV, I was using the lowest grade HDMI cable I had, one I paid $2 for on Amazon. So I took the cable from the ILO TV and went back to the living room to test it with the Philips TV. It produced the same crappy results as my other two High quality HDMI cables.
What I did notice though, is that it wasn't a lag from the nexus 7 2nd gen to the TV but a complete tablet lag. Everything was delayed by a half a second even while looking at the tablet vs looking at the TV. I have no idea why but I have no lag on one TV using my ps3 controller wireless and I have noticeable lag using the same set up on another TV. Also the lag shows on the tablet as well...
Guess it's time for a new living room TV. I wanted to get a bigger screen TV anyway but couldn't justify a reason. Could you tell me what TV you are using?
