could you send us a picture of the display when the issue happened? what model is the monitor?

did you only connect the board to hdmi, or did you connect it to both dsmi and dsi at the same time?

also, did you reboot the board when you modified the resolution?

thank you @tooz

I use this monitor.

I did only connect the board to hdmi.

I was setting with "Resolution Changer (ADB)" and "DPI Changer (Root)" , and each apps had same result.

This 2nd photo was setting resolution 1024x768 , and it was same after reboot.

hello @Hitchcock, 

some questions and possible solution for the issue:

q1. is the resolution of the 1st pic 1920x1080?
q2 . has the DPI been modified? if so, please modify the resolution to 1024x768(settings-> display-> HDMI-> resolution) and reboot; you can also try to flash the board to android 11 and see if it improves
q3. is the monitor connected to the HDMI port? or is it connected to a HDMI-DSUSB dongle? 

also, please use the commands in adb shell below to see if it works:

su
setprop persist.vendor.overscan.main "overscan 100,100,100,100"
stop
start

Thank you @tooz

I tried some solution.

a1) The resolution is 1920x1080 of the 1st pic.

a2) I could not modify the resolution to 1024x768. 

settings-> display-> HDMI-> resolution-> [1024x768 ] was can not found.

I am not try to flash the board to android 11 yet.

a3) monitor is connected to the HDMI port.

That commands in adb shell was not work.

"su" command was want a password , and I don't know correct password.

"setprop" command was "not found"
