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.
from:
http://dext3r.komodin.org/
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...
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.

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.

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.

I have only had my tf701 a day but Ive noticed sometimes when docked to the keyboard if you dont touch the mouse for a few seconds sometimes when you move the mouse again it will make a flicker around where the mouse is located, it doesnt always do it, just wondering if anyone has noticed this or is it a fault with my tablet?
I can live with it, but if there is a known fix it would be nice to sort it.
Thank You
After a bit of messing about I think it only does it with live wallpapers? Which isnt a problem as I wont be setteling on a live wallpaper anyway found them far too distracting.
Would still be nice to know this is fixable though.
Thank You
I was wrong its not to do with live wallpapers, just seems to do it on some apps, for example if I go to apex launcher then settings, if I leave the mouse for 10 seconds or more than rouch to move it, it makes the strange flash across the screen.
Could anyone else please test if theirs does this?
Thanks
Asus considers it to be a feature - not a bug - and calls it "smart backlight adjuster".
For most people it goes away upgrading to 4.3 which I guess you haven't done?

I have noticed it does it on the drawer too, only when using the dock and leaving the mouse dormant for 8 seconds or more than moving it again it sends horizontal lines across the screen for a split second, is this the bug *ahem* feature you speak of?

Also when you say adjuster, that sounds like it would be something that requires adjusting but it still does this with screen set to full brightness, or least brightness, with auto off, also wit outdoor on or off, it still does the strange flicker.
I can happily live with it, doesnt bother me that much just dont want it to be something that is going to get worse as Im very close to unlocking the device and dont want to blow all warranty if I already have a fault.

No what I had in mind was the screen dimming and brightening. What you describe sounds more like the "flashing black lines" the TF700 has (which seems to be due to some nvidia driver issue). I have not noticed those on the TF701 but then, I am so used to them from the 700 I probably wouldn't even notice. Have not read anything about them in the forums though, so I suspect your situation is unique.
Are you in the US? Get a Squaretrade warranty. I find the peace of mind is worth the $75 since they don't care about locked/unlocked...

Don't have the keyboard for the TF701 - yet. So I can't help you with your test.
The black lines on the 700 are benign - I don't even notice them anymore. But I don't think my 701 has them, so there is a possibility that your tablet has a glitch...

I don't want to be negative here, but waiting for Asus' response is pretty useless. Their support staff has two answers for questions beyond: "Where do I find my pictures?" and they are:
a) Factory reset, and if that does not help:
b) Send it in for repair - which may or may not cost you a bundle...
If you do send it in get written confirmation that your tablet is still under warranty first and take pictures of your tablet documenting its condition, how you packed and shipped it etc.

That is entirely different from what I thought it was and I have no idea what could be causing it. Do you get that ever when the dock is not connected?

No it cannot be replicated when the dock is not connected or when just touching the screen with or without the dock connected, it only does it on some areas of the system such as drawer and some apps if the mouse if left dormant for 8 seconds or so then moved.
I have done a factory reset and cold boot as requested by Asus, but the problem still persists as shown here in the new video

Mine definitely doesn't do that. Try switching the cursor mode to gesture mode for me and see if that makes a difference. (I doubt it will but you never know)
Then go to the system settings, about and click the build number 7 times to enable developer mode. Then go into developer settings and look for force GPU rendering and disable hardware overlays. Check both. Reboot - any difference?
Check the cables
When troubleshooting a screen flicker, I always check the cables first. Several TechRepublic members agree. Ian C B, Bruceb, Crjordan, and Aqmike all suggested checking the video and monitor power cables before doing anything else. Ian C B reminds us to confirm that the cables are screwed in tightly and to replace the cables with new ones to see if the problem persists.
"The color changes are almost always a faulty wire in the cable," Crjordan said. "Try working the cable back and forth near both connectors. If this causes the color change, you could have a broken wire in the cable, or a loose pin in one of the connectors. Make sure the cable is out of the way (from feet, hands, and other objects). You may also try zip-tying it to itself or another stable object until you can replace either the cable or the monitor."
Check the environment
If a cable isn't the culprit, then the user's workspace should be next on your hit list. Monitors are notoriously sensitive to magnetic fields. Speakers, florescent lights, fans, cell phones, radios, and any other electrical device can cause a wide range of monitor problems. (See Figure A.) "Check what's around the [monitors]," Vilefileman said. "Cell phones are known to cause screen flickers, among other things, and plugging a radio or fan into the same receptacle can also cause screen flickers."
Maybe its like some kind of electrostatic interefereence in your environment more to do with the power being supplied to the device. Check cables. Etc. I think its interference or something.

Then go to the system settings, about and click the build number 7 times to enable developer mode. Then go into developer settings and look for force GPU rendering and disable hardware overlays. Check both. Reboot - any difference?

I have noticed one other thing, it will not do the fault on first reboot, until the screen is locked, once unlocked it starts doing this fault
Gesture mode made no difference
Also done the developer options and they made no difference :crying:

I was wrong disabling hardware overlays does seem to resolve the issue?
However each time I reboot the option is un ticked that's why I thought it didn't do it

Check the cables
When troubleshooting a screen flicker, I always check the cables first. Several TechRepublic members agree. Ian C B, Bruceb, Crjordan, and Aqmike all suggested checking the video and monitor power cables before doing anything else. Ian C B reminds us to confirm that the cables are screwed in tightly and to replace the cables with new ones to see if the problem persists.
"The color changes are almost always a faulty wire in the cable," Crjordan said. "Try working the cable back and forth near both connectors. If this causes the color change, you could have a broken wire in the cable, or a loose pin in one of the connectors. Make sure the cable is out of the way (from feet, hands, and other objects). You may also try zip-tying it to itself or another stable object until you can replace either the cable or the monitor."
Check the environment
If a cable isn't the culprit, then the user's workspace should be next on your hit list. Monitors are notoriously sensitive to magnetic fields. Speakers, florescent lights, fans, cell phones, radios, and any other electrical device can cause a wide range of monitor problems. (See Figure A.) "Check what's around the [monitors]," Vilefileman said. "Cell phones are known to cause screen flickers, among other things, and plugging a radio or fan into the same receptacle can also cause screen flickers."
Maybe its like some kind of electrostatic interefereence in your environment more to do with the power being supplied to the device. Check cables. Etc. I think its interference or something.

Theres not really any cables I can check, I have checked the connection is pushed in correctly which it is.
I have just tried to replicate the error outside with my phone turned off inside the house so no chance of interference and the error was still present.
Don't think this is quite the issue as it only does it when moving the mouse after leaving it on certain apps for 8 seconds.
Thank you for the help though
I have looked high and low for a way to turn on my Nexus7 without using the power button while it is in sleep mode.
The reason is because i am putting my tablet in my 2002 Mustang GT to replace the stock radio. Once installed , the power, and volume buttons are no longer accessible. I have bought an AMP and use the remote volume knob to adjust the volume. Next my issue was getting the tablet to wake from sleep.
After some serious thinking, i have found a way.
This does not require flashing,hacking, taking the tablet apart to rewire ANYTHING.
What i am going to do is connect the charging cord to a secondary cigarette lighter, then plug in a USB adapter.
On the power side of the secondary cigarette lighter connect a toggle switch. (The secondary cigarette lighter will be hidden behind the tablet)
Mount the cool looking toggle switch somewhere in the car where it is easily accessible.
When you want to wake the table, and or charge it, turn on the toggle switch. (This SHOULD work with any tablet)
You may want to download an app to put the tablet to sleep for when getting out of your car.
If anyone else tries this please let me know how it worked out for you.
LOL
A great solution to a unique problem.
Let's see pics when you are done dash mounting your N7.
I still have to cut out a small piece of the dash to allow room for the charging cable. That will be done tomorrow, along with a better video. I just wanted to show my progress.

Here is another video i made during the day, and after it was all mounted.

Here's a thought, couldn't you just wave a little magnet over the bottom right part of the nexus screen? This should wake it up just as if you were opening a cover.

While that is a good idea, that doesn't help with charging.
I personally would want the battery in the tablet to cycle threw its charges instead of always staying connected. (in case i ever wanted to take the tablet out)
Thanks for the videos. Looks like quite the fun project. You did some great work there.

Thanks RoumoredNow. Its still a work in progress.
1. Better mounting of the tablet.
2. Add DC 4 port USB hub.
3. Add front and rear cameras.
4. Add 2 Standard USB connections built into the dash. (for passengers to charge there phone or play threw the audio system)
5. Another AMP
6. Replace the stock 8 speakers.
7. Add Sub-woofer.
8. Anything else i may think of, or suggestions i may like.
This is just an update to anyone wanting to mount there tablet in a mustang.
I have found that a simple piece of plywood does the job well. the area to mount a tablet in a mustang (without cutting up the dash) is about the same thickness as the tablet.
So using a piece of plywood, you can screw it to the BACKSIDE of the stereo mounting bracket. A couple of pieces of Velcro added to the plywood and tablet will keep it centered and in place while putting the radio bezel back on.
The Velcro also added cushion and a space filler to snug the tablet up to the radio bezel.
See images.
Just remember that baking a tablet in a car all of the time _will_ destroy the battery, and rather fast. Maybe that's fine. Just warning you.
As for turning the device off. If you have bluetooth in the car or something, you could use Tasker to watch for the BT device. When it goes away, start a timer, maybe 30 minutes or something, then shut down. That way quick runs into the store or it's not powered off/rebooting etc. There are many posts on this exact same subject in this exact sub-forum... Nexus 7 seems to be popular for cooking in vehicles for some reason.
But yes, the "unplug it from the power" solution is always the solution. Using a "pretty" switch is one way to do it. Some cars have lighter ports which are only powered when the car is powered, but I know mine are hot all of the time and a lot of cars these days are.
Use mKernel and a ROM that supports it and you can use the double tap to wake function, works great on my tablet, just tap the screen twice to wake it up.
U can use timur's kernel, And a otg-y cable, so when power unplug nexus go on stand by, And when plug power nexus start.
That rom is created Just for car installation.

**EDIT: The ebay item i bought below does not fit well in the nexus7.
While it does fit, and does charge, it is loose and sometimes gives a bad connection then disables charging. I suggest to NOT buy it for a nexus7.
I just wanted to update that i have got my OTG cable for my nexus7 (2012) and it works great with timur's rom. Here is a link to the 1 i bought from a USA seller.
I have used a 16gig USB stick with it for testing till i get a larger 1.

A couple of things i wanted to point out about having a toggle switch connected to wake my tablet.
PROS:
1st. This will allow you to charge the tablet when your not in your car.
2nd. Your car does NOT have to be running or in accessory mode to charge your tablet.
3rd. Depending on how you wire your amp, you can still listen to music on your tablet when the accessory is off.
4th. You can still use ftp, AirDroid, ES File Explorer, ect.. (As im typing this, i'm transferring over 600 songs to my tablet in the car.)
CONS:
1st. Tablet does not wake when switch is moved to accessory mode. (toggle switch must be pressed)
There may be more cons, but i haven't found any related to my setup yet.
I'll add to this as i run across PROS and CONS.
my sETP N HELP PLEASE

****VERY IMPORTANT OPINION*****
I RECOMEND YOU SET A FUSE BEHIND EVERY WIRE TAP YOU MAKE, I HAD TO REPLACE MY ENTIRE WIRING HARNEST DUE TO A SHORTAGE.. SO A FUSE WOULD JUST BLOW AND NOT CAUSE SHORTAGE> :good::cyclops:
This post is old but I still have problems. Anyone had luck or did you just threw away your old and got a new model instead?

The thing im using 4.4.4 rom and I believe timurs kernal is only for 2013 version of nexus 7. (Might be wrong) what I ended up doing is making a switch wich in case my battery dieson the tablet I can turn on the switch and charge the tablet over night even when the car is off..

I have 2 nexus7 (2012) models. My first one, i had timurs USB ROM for Nexus 7
I never could get it to fast charge even when fast charging was turned on. i was backing up my music and the rom went into a boot loop while it was backing up. So i tried to clear the cache and that didn't help. i then tried to revert back to factory (4.4.4) and i bricked it. It was hung at writing the bootloader. So i left it all nite while i went to bed and the battery died.
My 2nd tablet i left stock (i haven't even tried rooting it yet).
