Does anyone know if there is a way of turning the screen off when screen mirroring to a TV via mhl? I plug my phone to the TV to stream netflix but it really drains the battery partly because the phone screen stays on.

Here you go. Root is required.
Thankyou Ma'Lord...
Just one problem, looks like Win 8

Just like the post says my hdmi works sometimes and most of the time it doesn't. I had it working last night watching nerflix and it just stopped, same thing happened today. I am running a Zone23 Rom and bcblend 02 kernel. The mhl adapter I am using is from T-Mobile. Does this happen to anyone else, is the a solution I can try? I just ordered the htc adapter to try that and I have already switched hdmi cars to see if that was it and it wasn't. Any help I would appreciate.

did you connect the power cable as well?
Yes, I know I didn't mention it but yrs the power cable is attached and working, I guess it was my fault for not clarifying it better, it use to work whenever I plugged it in not it is hit in miss with a mostly miss.

sounds like a loose connection. probablly a faulty hml adaptor.
Also, sometimes when it kind of was acting like it wanted to work it would cut on cut off like someone was flicking a light switch on and off.

Well I ordered a HTC mhl adapter and the same thing happen. So I ended up restoring a rooted stock rom, re-applying all my apps, backing up my new setting, wipeing and re-installing my Zone 2.3.4 ROM and re-applying my new setting and it still didn't work.....LOL
But it now works on my 55 inch vizio but not my 46 inch Sony in my bedroom where I would use it the most.
I don't know what the problem is with the Sony because it use to work flawlessly but now it doesn't even read it. I know its the tv because I have swapped everything else, hdmi cable, charger, and mhl adapter. If anyone knows what may have caused my tv to stop reading my mhl adapters please let me know?

Your TV port probably failed. I know hdmi ports look robust like a usb port but they really aren't.
Well my tv has 5 ports and none of them are working with the mhl adapter but the still work with my DVD player though.

Old thread but I may be able to help others.
I have a generic HML adapter from ebay and I found that you need to connect things in the correct order to make it work reliably. I had the best results following these steps.
1. Connect power to the adapter
2. Connect the adapter to the phone
3. Connect the HDMI cable to the adapter
With the stock rom I found a reboot of the phone between step 2 and 3 sometimes helped but generally it was not needed. With the leedroid rom I using now I've never needed to reboot.
Unfortunately my 52" Samsung LCD (2008) has no audio but my 24" Samsung LED (2011) works perfectly every time. I got audio to work 2x on the 52" but I can't for the life of me figure out how.
Just to further update....
I found a firmware update for my 52" Samsung TV on their website. After applying the update I found the HDMI to slightly more reliable with my audio issues but it still did not correct it 100%. I have audio issues 1 out of 4 times now so by my best guess the TV has to comply with the newer HDMI specs in order to operate with the MHL adapters.
Hopefully this helps someone out there.
Appreciate the tip, so how does one update their tv

hows the vid quality?
monoprice has adapters for 14 dollars. Also since its a digital signal u don't have to worry about the quality of the picture. If it works it works if the signal is bad it won't work.

Well, it is about what you would expect from WVGA stretched to a 1080p screen. Not bad, not great.
So it will record 1080p but outputs it at 800x480 via the hdmi? If that is the case then that's extremely disappointing.
I think it changes resolution when playing video. Notice how the screen blanks out briefly before playback begins? I think that's the resolution switchover. At least that's what happens on my international SGS2...
I want one.. but is it worth it? lol
just wanna verify that it mirrors your screen, correct? so its fully operational while outputting?
Complete mirror of screen. Can confirm movie playback is in 1080p. Fully functional.

How do you mirror your screen? I have the phone connected to the TV through this Micro USB - HDMI adapter, but I see nothing on the TV when I play a video.
UPDATE: I think I answered my own question by reading other threads: you need to actually separately power the adapter through the USB port on its side. That's a bummer, so you actually need a separate USB power source!

Mediahub files blocks hdmi out.
Works if i play first then plug it in.
But once i move files off mediahub to sd card, that trick doesnt work anymore

Ya mine is being blocked as well. I bought the OEM Samsung one to watch my media hub stuff. Kinda disappointing. As stated before if you start the playback before you plug it in it works quite well.
So I just picked up an adapter locally and while it works just fine, I'm not sure it's working as it should with regards to charging. If I simply have the adapter plugged in and then plugged into the wall, it charges very very very slowly. If I actually plug in the hdmi cable and do something like stream a video, buh bye battery life. It drains crazy fast.
This adapter from Amazon, does the charger help keep the battery at around the same level while in use or do you see it drop a good bit as well?
Oh and with regards to MediaHub, whether I start a video before hooking up this adapter or after, I still get the same error on my tv about protection, etc.

In regards to charging this phone charges slow and if your using it watching video it will just barley keep up. The phone seems to use almost as much juice as it get from the charger as your watching video.

So how do you get this working? and it puts 1080p video on the TV through the USB>HDMI from our i777?
What is media hub?
Anyone try a MHL-VGA with this phone?
I've tried a few adapters. There's 2 different adapters from Samsung the one with product #2 worked the best for me its on Amazon I got it for 25$ and works well. Also mirroring works even better with a launcher like adw ex as when it switches into landscape mode it looks great on a big screen

The menotek cable drops the connection, so it is worthless. I don't know if the official Samsung one is better, but I had to keep getting up to fix the menotek.

I'm interested in the exact same feature. Seems wasteful to have two displays running.
I have done extensive reading on this tonight and thus far are unable to find a method that will turn the Atrix display off, while connected by HDMI. There was one interesting thread for the Xoom that will turn the display OFF, while leaving the HDMI ON. Also, references to video players that recognize when hdmi is connected and turning the phone display off. Nothing that I have found that will function on the Atrix. Other member ideas would be much appreciated. Thanks.

Hey Everyone. Not sure if this is normal, or just because of my setup mentioned above, but the resolution from my Prime to my HD TV isn't very good, and is very pixelated. Is this a normal thing for bringing a prime to a TV through HDMI, or
Is there something specific everybody else is doing, or does anyone know of a solution?
It may be because of the DVI, but my cable box uses that too and the picture there is great.
Thanks again for any help.

I haven't had good luck with HDMI-to-DVI adapters with my Prime either. In fact, the one that I tried didn't seem to work at all, even though they are supposed to be electrically compatible...
"Because HDMI is electrically compatible with the CEA-861 signals used by digital visual interface (DVI), no signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used." - http://en.wikipedia.org/wiki/HDMI
I have not had a reason to use dvi yet. HDMI works great for me. I use it to stream movie s from my network-through the tf201-to the TV.
I do remember, now that i think of it, that i hooked up my prime to a tv in my office, the resolution was not very good. I will test it again today when I go to the office and report back.
You should try finding a a tv that has hdmi input and test that to see if there is a difference.
I'm just happy JB supports DVI. ICS did not and I have a projector with DVI-in. I decided to give it a quick try and it has some rather large pixels. I have a modest projector, so the "screen door" effect is normal, but this however, is much more exaggerated.
again, happy it even works.
Thanks you two. I'll check with a regular TV with HDMI and see what happens.

I'll also invest in a better adapter, and see if that helps, and let you know what helps.

Pretty sure there is an xposed module for full screen HDMI. Look into it. I haven't used it myself.
