Display resolution lockup
#1
My first Tinker Board.
Connected via HDMI to a Mitsubishi 65" rear projection TV.
Desktop display is out of bounds. I need to lower resolution or resize screen.

I have a Tinker board S. I loaded TinkerOS Debian v2.0.8. Display resolution defaults to 1920x1080. When changing resolution to anything lower, in my case, screen goes black. The screen comes back without a resolution change and everything is locked up. I have to power off and power on to get back to square one.

How can I change the resolution or resize the screen without locking things up?


Thanks for any assist.

im amazed a rear projection tv has an hdmi port, my guess is the tv can only support one resolution, due to it being old technology

I'm facing a similar problem with a Toshiba REGZA 32. The initial screen is beyond the visible size. I used to adjust to 1440x768 by xrandr.
It's hard to find the menu bar to open a console terminal, but with the key combination ALT+F1 I can open it and find the lxterminal.
So for this use case, first it should need to find which resolution is accepted by the monitor
Code:
$ xrandr --verbose
So one of the possible monitors will be described with all possible resolution and which could be set.

When found a valid resolution, then the command can be added to ~/.config/autostart with a .desktop file.
