I got an old Samsung S8 with some widescreen display, now I want to connect it to a 4k tv but I would like to use the whole screenspace without black bars. So can I set my phone to output 16:9. Maybe using Tasker?
Ok I got it done. Using Tasker with "run shell":
wm size 2160x3840
dont forget to check "use root" puts the device in 16:9, and I'm using the external screen resolution here, If I do something like HD it will only output HD and I want to have it in 4k.
Going back works with the internal screen settings menu or you create another task with the devices original resolution and aspect ratio.
Also combines nicly with:
setprop persist.demo.hdmirotation=portrait
To have that whole HDMI output in portrait mode.

When I hook up my prime in r my 720 p TV everything works great, shows the whole screen. But when I hook it up to my 1080p screen it cuts off the outer edge if the screen all the way around. Thick enough to barley see the apps icon on the home screen. But it also does this on my Acer a 500, so I think it is a android issue. Is there a setting that I have never seen before to fix this?
Also I made sure its not the zoom, wide or stretch feature on the TV

this is an issue with your TV enabling overscan of the HDMI image. on my panasonic plasma TV i had to troll through the advanced picture settings and change the "HD Size" to "Size 2". i don't know why panasonic makes this the default but that's how it goes. once that setting was made the display was a perfect 1080p crop. changing zoom/wide/stretch doesn't solve this problem because all that does is adjust how a sub-1080p image is presented on the 1080p surface.

My TV used to do the same, it's as he says: find overscan, give it the boot!

It's just the settings on your TV.
You will need to choose a different aspect ratio on your TV settings
That's what i thought, but when i when in the image settings, i just saw things about color, brightness... I got a bravia...

I don't use Sony but there will be a settings for aspect ratio somewhere. Take your time and look for it.
There are many options on Samsung; full screen, crop, 16:9, 16:10, zoom etc

If you have had a thorough look through the image settings then it may just have it's own dedicated button on your remote.
I have a Panasonic Viera and I have a button on my remote which is called "16:9". This is the only way I can change aspect ratio.
Look on your TV or your remote for a dedicated aspect ratio button sometimes it's a square with an arrow in it. Obviously it's differnet for different models.
Either look in your manual, or google it.
Your TV will definitely have a way to change aspect ratio, you just have to find it.
I found the button, few choices but.none that makes it fit or even smaller...

I bought a MK802 for a Car PC project that I am doing. I use to have a Windows based Car PC, so I already have six 7inch VGA w/ touchscreens installed. I bought the MK802 specifically for salvaging the screens and because of Androids mobile diversity.
Issue 1: The touch panel is USB based. I plug it in and a mouse pointer pops up on the screen. I am able to move to the left and right correctly. But up and down are inverted, so when I push on the top of the screen, the pointer is at the bottom and when I push at the bottom, it appears on the top. Is there a config file I can edit? maybe switch the commands for up and down?
Issue 2: The MK802 are built for high definition displays with high resolutions. I used a HDMI to VGA converter to convert it to the port I need. Issue is that the screen can only work at a resolution of 800 × 480 (1,152,000) pixels w/ display format: 4:3(800*600 default), 16:9 is optional. When I plug the two together, the screen turns to a red color. Thats with MK802 on 720p. Now if I change it to 480p, I can see the screen, but its not sitting correctly. Is there a file to adjust the resolution to a lower one that will make the screen happy?
Any help would be appreciated.

I think this can be done in screen. I remember seeing that in its option menu. I will test today and see if it works. Also, I noticed that I cant adjust the the format on the MK802. I had screwed something up and flashed the ROM to their supposed latest ROM. It adds a ton of features that seemed to be missing before, but has taken away other features like resolution adjustment.
How did this ever turn out. im looking into to doing something very similar. what do you use for sound processing. any help would be awesome.
Having an unusual problem with outputting my AT&T Galaxy S2 (stock rom) over MHL to my television. Most stuff looks fine and is properly mirrored, but a couple of video streaming apps I use have an odd aspect ratio problem. Instead of mirroring exactly what's on my phone's screen, which looks fine, the video on my TV is forced to 4:3. (Not a big Netflix user, so this isn't one of the problem apps.) My TV doesn't have very many aspect ratio options, so the only change I can make there actually doubles the size of the black pillars. Is there anyway to fix this? Another thing I've noticed is that when it's outputting this way, the notification bar is still visible on my phone's screen, but it disappears on the TV.
On my Samsung s9+, using the "Smart View" feature allows me to view the screen and video (from, for instance, the TiVo app) on my fire stick. On my M5, using the "MirrorShare" feature, the screen sharing works right up till video starts playing, then all I see mirrored are the video controls, but not the video itself, it is all black (the sound comes through though). Anyone know why this would be? Is the M5 screen resolution too high to display on a 1080 fire stick or something? (But the samsung has a higher resolution than 1080 display too). Just curious. I can stick with the phone for screen sharing for now.
