Hi.
Just tried playing with RemixOS on a media center pc that I have attached to my TV. At the moment this pc is running a regular linux distro, but I thought it could be interesting to see how Android would work for this purpose. Problem is that my TV is an older 1080p 46" that suffers from an old issue where a large part of the screen is placed behind the massive border on the frame. As such, when running at highest resolution, I loose parts of the screen on each side, top and bottom. I found that running 1366x768 fixes this issue.
RemixOS of cause, is running at 1920x1080 by default, just like any other OS that I have had attached. Difference is that I have no way to change this. I tried changing DPI via kernel boot arguments, but this did not work as it should. The calculations for DPI
Code:
sqrt(1366^2 + 768^2)/46
states that the DPI should be set at 35. But doing so makes everything 100 times smaller on the screen.
How can I get this TV working with RemixOS?

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!
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.
Hi I have a Windows 7 laptop connected to my 42" HDTV via a Vga cable. I finally figured out how to get the screen to only show on my TV. To do that in Windows find your menu.lst file and use Notepad to add this line at the bottom: DATA= CREATE_DATA_IMG=1 video=LVDS-1:d
initrd /RemixOS/initrd.img
boot
This would be for the 64 bit Remix OS for PC version. So at bootup what happens is it switches to your external monitor and leaves your laptop screen black.
The resolution that it auto selected for my HDTV was only 1024x768 at 60hz. I used the hotkey Alt + F1 to open the Terminal. I type the command wm size 1920x1080
It does change the resolution but it looks centered on my TV with large black rectangles on top, bottom, left, right. How do I get it to show full screen? Thanks for any help and keep up the great work!
I had the same problem with my laptop. The only solution I came up with was opening up the laptop and removing the LCD cable.
Anyone else have suggestions?
Hi slipsystem,
You still have the same problem as me where even with 1080P resolution its still centered and very large black bars on all sides correct? You're not able to get it to be full screen right on your TV? If you use the commands I posted you can plug your lcd cable back. Also I forgot to mention when opening up the Terminal in Remix OS with hotkey Alt + F1, to exit the Terminal use hotkey Alt + F7
I'm not a programmer by any means, but in Ubuntu and Remix OS for PC, there is not an easy way to get it full screen on my 42" HDTV. In Windows its so easy, you right click and change the resolution which it will change on both the laptop and the TV. I hope Google makes it easier in their future builds because many people use an old laptop to watch in their bedroom TV, etc. Thanks.
I changed the digitizer and display in my phone. The digitizer seems to think its resolution is larger (1080x1920) than the real display resolution (720x1280), so my touch is misplaced. I know how to change the display (physical) resolution using wm size, but that scales the digitizer resolution proportionally.
How do I change the digitizer resolution?

Output of dumpsys display: pastebin.com/bwkjXHxH
(The phone is Lenovo A7000, but that shouldn't matter. The error persists after upgrading firmware, rebooting etc. I haven't flashed/rooted - yet.)
After using adb shell wm size ----x---, did you try adb shell wm density ---? Density is basically the dpi of which the device will utilise
Good luck.

Thanks, but yeah, I tried and it doesn't affect the digitizer resolution either, none of the wm options do anything worthwhile.
It seems I need something like a way to change sizes of SurfaceFlinger layers.

SurfaceFlinger is integrated into the GPU if I am correct, so good luck with changed that
Other than that, at the time of writing, I can't come up with a solution.
Wish you best of luck
Just going to add that I have a similar yet different problem to you.
The similar part is I too also need means to change digitizer resolution but instead of going from 1080p(FHD) down to 720p(HD). My scenario needs to go from 1080p(HD) up to 2160p(UHD)
So I'm just adding more traffic in hopes people know of commands specific to the digitizer or a method to locate & modify files which report the device as only 1080p to most apps
See I've tried Shell/ABD commands but unlike most phones giving my phone a command to report itself as 4K to apps is creating an issue because seemingly even though the device knows it's 4K it reports to itself/apps as 1080p so my the digitizer is running itself as 1080p even though the hardware is sending a 4K signal to light the screen even if most times what's displayed is simply 400% 1080p
If anyone knows what files to get to (as well as how) I as well as OP can manually add the appropriate values to use the correct amount of our screens whilst utilizing the correct resolution, because like he said the PDI stuff isn't related to digitizer only display scale, we need digitizer scaling

& to clarify when in 4K all the time mode with the ABD/Shell command it's not like I can use the whole screen to touch but it'll scale that touch to 1960 by 1080, not the touch for my case is 100% accurate to where I place my finger, issue is that its only sampling 1960 by 1080 of the pixels aka just 1 corner so only useable quarter of the touchscreen with the other 75% completely dead
