Hi
Any possibility for turning off the screen when I am using mhl tv out?
It doesn't makes sense that the screen it is on with the same image all the time.
How do you plan on doing stuff without using the screen? I can understand if you want to have it turned off during movies, but isn't it possible to turn the screen off and still get the image on the TV (when you're watching movies etc.)?

No, it isn possible.
If you turn the screen off, then the tv doens't play anything, thats because I ask.
For movies or flash on phone streaming to tv I don't want to have the screen on but I can't put it off and continue playing or I don't see how to do it
up ?
probably isnt possible, the same as with conencting a laptop to the tv via hdmi, the laptop cannot be shut and still plays the video
well i have a Blackberry Playbook + Galaxy Note, the playbook has an amazing option (would be great if they could put it in the Note) they have presentation mode for videos, u press it and then u can hit the off button, the screen will go off but the video will keep on playing
I am using Galaxy Note too. The reason why we need to turn off the Mobile Screen while playing movie, is because of the performance.
I read somewhere that the movie playing on TV is having bad performance because the phone has to render for 2 displays, hence it make the playback lags.
I bought MHL cable and it's really a waste that I can't have a smooth playback of movie...
I haven't tried it yet but maybe a combination of the TegraDisplaySelector.apk with chainfire3d will allow us to turn our screens off.

This widget app will give you the option to be able to switch between LCD and HDMI output, so you can preserver battery power, and disable any
annoying display enabled on lcd while using your TV.
you need to note, that managing the display is best with a mouse, but you can still use the disabled tablet screen for controlling your screen, but its not easy.
Remember you need to add this to your screen as a widget, thats the only way to access it, and it require root access to run the lcd vs. hdmi functionality. It does not work on android 3.x, as the library does not appear on that release for now

I get absolutely no lag on HD movie playing over MHL
but i agree that having both screens running is completely useless
when watching a movie

A little off-topic, but yes you can. Windows button + P will shut the computer screen off and only show the image on the TV.
nothing new?
Interested in a solution to this myself. Why burn the pixels when there is no need? Im a bit uneasy trying out the tegra solution presented above. I am heading to the play store to see what is available as far as presentation apps and such.
Wanted to bump this thread back up. Has anyond found a way to turn off or disable the phone screen while using the mhl hdmi out?
Like others mentioned its silly to have the phone screen on at the same time your watching a movie on a tv screen. There should at least be an option to disable phone screen while watching movie.

just did this to see that answer in ur notfications
No solutions yet? Would be nice if MHL mode could disable the phone screen for saving energy while improving HDMI video performance. I'd like to use my Galaxy Note as a netbook with external bluetooth mouse and keyboard, so keeping the phone screen on would be useless.
MHL does turn the screen off - but seems only while using built in player and playing a movie. At least it works like this on android 6 and Note 4. I am interested however in using KODI with the screen off while playing media...
Just posted this as a reply to a thread in 'Themes and Apps' but thought it belonged in 'General' so I've echoed it here. The Admin can feel free to remove the double posting, take away my birthday, etc. if I've broken the forum protocol
==========================
I connected my HDMI cable for the first time since upgrading/rooting ZV8 and I couldn't get the screen to mirror. This is something I've used/done quite a bit before the update and I never had an issue at home or in hotels while traveling. Now for some reason the screen doesn't seem to want to mirror.
After fooling around with it for a while, I'm starting to think the problem it could be tied to the G sensor position - when connected, I'll re-position the phone and when close to landscape/vertical the screen will mirro of a few seconds and then quit. Could someone with rooted ZV8 give this a try and let me know if they're having problems?
Here's what I've done/observed:
I've rebooted and re-tried
I've checked all the right boxes under settings - connectivity
I've toggled screen resolution - 480/720/Auto
The status bar properly reports when the cable is connected and indicates the screen is mirroring (but it's not)
Most times the sound will mirror and occassionally occassionally the screen will do so but only for a few seconds.
Tried this with HBOGo, Netflix, and just swiping across home screens
Sometimes the screen mirrors nothing and sometimes a blue screen.
I get this same issue on my Galaxy Note...I feel your pain man, no help anywhere.
Are you using stock or broken out? Have you tried using in portrait mode and let the video load into landscape..?. I know my hdmi port on my phone is a very loose connect and I have to have it standing on end to get it to work. Cant say anything about sounds working or not I use a LCD monitor with no sound capabilities so I plug speakers in. Haven't had any software related to hdmi issues while on broken out...

Problem turned out to be a damaged cable. i replaced my $2.00 HDMI cable form Amazon with another $2.00 HDMI cable from Amazon and it solved the problem. We'll see how long this one lasts . . .
so i just bought a MHL adapter for this in hopes of it looking good on a big screen. connected it to my 19" monitor first...popped up and it looked ok. icons were a little bigger than what looks compared to on the device. so using my BT mouse and keyboard i did some browsing around through some apps...not a good experience at all. then i noticed it cut the edges off on all 4 sides by just a little bit. look horrible. i thought it was the monitor, so i moved it to my 42" tv.
so connected it to my tv, again, cut off the edges, everything got larger. if you get a notification, the bar is so big u need to scroll down, not ideal, looks cheap.
tried web browsing, not as bad but every time you click on something to insert txt, a HUGE keyboard shows up that you have to hit back button on mouse or keyboard to get it to go away. cant get around this because to connect BT keyboard need to have the samsung keyboard active. maybe will be different using smart dock and usb keyboard. the notification bar takes up so much space along with tabbed browsing and address bar that 1/3 of your screen is gone.
the audio sounded horrible via hdmi, didnt try to use a 3.5mm out at the same to see if that would change.
oh and it eats battery.
did anyone else try it and have better luck? will the smart dock do a better job?
To get rid of the on screen keyboard while using a secondary monitor, download "null keyboard" from the play store. Also, I agree that the hdmi experience isn't anything to write home about, but it is useful for watching downloaded movie's, or browsing YouTube. I use a handheld bluetooth keyboard, and it's usable, but not too pleasant.
the reason why the edges are cut off isnt because of your phone, its because of your TV. you have overscan enabled. disable it.
as for the keyboard, yeah, i noticed that as well. it seems to only really go away with the default keyboard. kinda annoying =(
I believe with the smart dock the keyboard doesn't pop up if u have one connected

whats overscan? i tried looking at every setting for picture..didnt see anything ..
The MHL should have a power connector because of the high power consumption of the device. It needs to be plugged in. I get great sound over HDMI, maybe your video has a bad encode?
I will agree, on a 40" TV it doesn't look too great, but then I didn't transcode for a large screen either...
Would running a custom rom stop from the mhl hdmi to work?

Hdmi sound is digital. Something is wrong with your setup
swyped all these spelling errors from my galaxy note 2
Greetings i just bought the original Samsung MHL for note 2 and galaxy s3 today .
To be honest if you want to play games , or do what you normally do with your phone its very laggy and bad quality picture.
If you want it to watch movies, youtube, music, Photos e.t.c ( Multimedia) its great . The video engine its totally different so the video output on screen its very nice and the sound very good.
So if you dont have a media center home or smart tv or whatever its good to have . If you have then its a bad investment you can not do much on screen even with BT keyboard.
Oh , browsing its ok...
I expected more but unfortuantly thats the deal, i dont know if someone running 4.1.2 can confirm better performance on mirroring , games etc. i run stock on latest update 4.1.1 .
Cheers

I own the Smart Dock and the virtual keyboard doesn't pop up when connected to USB KVM.
As far the display not fitting the screen there's a tools button on the Samsung TV's remote that allows changing the Picture Size to Just Scan so it fits properly.
For the most part it works well except for a few minor quirks but it may be related to me connected to an Avocent KVM to use one set of monitor, keyboard and mouse for all my devices. For anyone with Smart Dock, does holding down both shift and space bring up English(US)?
Yes this is overscan. This is common place with home theater pcs. Typically tvs don't have much functionality when it comes to dealing with over/underscan. Luckily with pcs, gpu drivers do.

Same deal with using the allshare cast hub, got the cutoff screen untill I adjusted my tv settings. The only issue I have with the hub is that ive noticed the sound lags a tad. Love everything else.

so is overscan on our tv's something we have to live with?
You can turn overscan off. Just look in your televisions picture setup. The scaling should be done by your phone. Not the telly.

The stock video player plays full screen and correct aspect ratio. Random regular apps like gtalk display full screen and correct aspect also.
Netflix squishes into 4:3 for no explicable reason.
It's not the particular video on netflix since it looks right on the phone screen and it looks right on the tv too if I use my ltevo to play the same vid via mhl to the same tv over the same hdmi cable instead of the gn2.
Stretch to fit doesn't correct it either. No zoom/aspect option corrects it.

Thanks, I have a Samsung 40" tv so I'll check it out later tonight to see if that option is available. I'm really loving this mhl cable though~

Yes netflix is squished into 4:3 on the smart dock too and probably on the allshare cast hub but I don't have that to test it.
The squish thing Netflix does is just Netflix and whatever coding they did for the app. I think it does same thing on the GS3.
Hello,
I've got note II (stock rom 4.1.2) and Smart dock. When I connect only keyboard pendrive etc (not mouse) to the dock, and connect all to TV (hdmi) the phone's screen is still on. In this way I have very good framerate. I can play games and watch movies. Ecerything works like a charm. But when I connect the USB mouse, phone's screen is off. It's good for that purpose, but after that I've got really big problems with framerates. Films are not like 25fps, more like 18 to 20. I don't know why it works like that.
I have still yet to reproduce this effect. I can only assume its something with your ROM or maybe the USB mouse. Mine works and I never see a frame rate drop.

I've tried two logitech mice. I've got last stock rom drom samsung 4.1.2. Does the screen off in your device when you connect mouse? Because i think the problem is with this feature
Yes. I actually dont even use my wired mouse. It is only connected to auto off/rotate my screen. Does your TV have the option to set display to 720p instead of the 1080p the DOC defaults. I managed to replicate a FPS drop when connecting to a friends TV. Checked settings and it was displaying at 1080p. Changed it down to 720p max and it cleared right up.

Actually my tv don't have such option. This issue is strange because without mouse all is extra smooth
I can vouch for the OPs Smart Dock issue as I have had the dock for awhile trying to isolate the same problem. Its not a rom issue.... if you look at NZtechfreak's (google search) review of his early loaner sample from Samsung, he didnt have any noticeable sign of this issue..... but if you notice at the end of his review he states that one issue is that the screen does not turn off at all while in use.
Samsung must have updated the software to recognize when a mouse is connected and for the phone to shut off the screen for display just on TV or Monitor..... however they updated this function, screws up the output. I have no 720p tv's or monitors to verify if it does not have the same effect but on my 1080p Sony & Samsung TVs, and my Samsung & Generic monitors, it happens. (either 1080i or 1080p is how the dock is detected on my displays)
Ive already tried reverting my Note 2 back to complete AT&T stock, different HDMI cables, different mice (both basic wired and wireless) and all combinations work fairly smoothly up until the point you plug in the usb cable/dongle of a mouse, then it switches off the phone's display and you can see how the smoothly mirrored output on your display begins to lag.
Its easy to notice if you mirror a movie or run a game on the phone while in the dock and seeing it displayed on both screens the just keep plugging in and out a mouse to the dock and you should see the difference.
Hopefully this Smart Dock is firmware updatable and Samsung fixes this ASAP.

yeah, I hope so too since I mainly bought this to play games on the big screen and this bug makes it unplayable unless you stick to the simple ones like angry birds or something. As for my MC4......forget it! at least I can browse and watch streaming movies still.... just have to disconnect the mouse each time.
I am wondering if BT mice do not cause this issue since they bypass the dock?

With BT mouse screen is on and everything works fine. But when you are watching videos it's shown on overlay without subtitles etc and you have to force landskape mode because phone still things that it doesn't have mouse.

Recently I bought the HDTV adapter for my Nook HD+ and I'm trying to find the version of CM that will work best with it. I could not find this information through searching the forum.
My Nook had CM 10.1.3 the first time I tried it and it did not work particularly well. It was in the wrong resolution and did not display full screen. I did some searches on the forum and found that updating may fix the problem so I updated to CM 10.2.
CM 10.2 seemed to work better. Video looked much sharper, but 1080p video was choppy (probably because the Nook is playing the video on both screens) and still would not fill the screen.
Is there a version that has perfect or near perfect functionality? I really just need:
-not choppy 1080p video, games and emulators to play in full screen
-when playing a movie the Nook will normally display, "Playing on TV" so that the nook only has to render video on one screen
Are both of these possible?

I think that depends on your tv. I have two tvs at home and one shows as full screen with default setting, and the other one doesn't.
Try to change the scale setting of your tv.

I appreciate the response. Unfortunately I have tried to change the aspect ratio settings and none of them fix the full screen problem. I've tried every screen setting on multiple TV's and there's no way to get full screen. I also tried the Resolution Changer app and that did not work either.

I have used the HDMI adapter a lot with different Nook HD+ roms with no problems. I have found that the video player i use on the Nook makes all the difference with the play back quality. I use MXplayer but you may want to try a few to find the right fit for your Nook

I do have MX player also that's a good player. I updated to CM 11, Wiped data & factory reset, cleared the cache and video seems to be in full screen now. It still plays on both screens though, but I guess that doesn't matter. I wonder if anyone knows how to make the video only play on the TV?
The HDMI adapter was originally $39. If I paid that much for this piece of $hit, I would have shot someone. It is garbage and not worth the hours of your life you will spend on it. Even with it works, it stops working if you fart (literally) or bump it. And when it does 'work' the resolution is for crap. If I could roll back time and have given a homeless person $13 and never have seen this disaster, I would have done so in a minute. It is the single most shockingly low quality piece of trash I have encountered in the modern era of electronics. Spend another $15 and get a raspberry pi or something.
I'm disappointed in the HDMI adapter as well.
The fine print in the specs rate it at 24fps @1080P, which is unacceptable.
That's part of the motivation to get Wi-Fi display/miracast working, plus the latter doesn't need a cable.
With Wi-Fi display working and wiimote support, one would have a nice functional media center using xbmc/kodi.
