I have some problems with screen resolution. I found the link that could probably describes the solution:

https://help.emteria.com/kb/716026#custom-screen-resolution

but it does not work. Any hints?

Hi Staszek,

This article is outdated and shouldn't be used. We do not recommend this type of changes anymore, as it often leads to a broken installation. What are you trying to achieve?

Hi kalkow,

I want to use emteria as a base of smart tv. The issue I figh with rely on difference between rendered display and one physically shown. The cropped spaces are about 5 to 50 points. It is annoying becouse all right sliders are unvisible. The problem is probably on kernel loading phase. I tried to chenge resolution on raspberry pi settings but get nothing (black screen). Also the list of avaliable modes is empty in settings. So, I tried to setup up mode at boot time.

Best trgards,

What screen are you using? What resolution do you see in the settings? Which one do would you like to have?

Hi,

Screen: samsung plasma tv set
Resolution: default 1280x720@60 provides image cropping. There is no other mode in settings. Also, I tested various of modes got from rapsberru pi os for example: 1920x1080@60 (prefered) and got a black screen.
What I want: any (large) image resolution without cropping.

Best regards.

Android on RPi 3 doesn't perform well on big screens. Maybe it will get better once our support for RPi 4 is ready.

I probably found solution to my problem. This is sequence of entries in /boot/config.h:

disable_overscan=0
overscan_top=xxx
overscan_bottom=xxx
overscan_left=xxx
overscan_right=xxx

I will try it tomorrow. Before that i have a few questions:

1) Is it possible to change this entries from settings?
If not:
2) Do I change any other then config.h file ?
3) Is it possible to modify config.h (and any other files when necessary) from something like console ie without changing iit/them on external linux box?

Best regards,
