The bone-debian-10.10 system cannot recognize the resolution of 1024*600 of my display

When I’m using a 7inch HDMI LCD connect to the BB Black and using the bone-debian-10.10 with GUI interface, the system only recognize the resolution of the LCD to 1024768, but the hardware resolution of the LCD screen is 1024600, so the LCD cannot display normally! How to modify the resolution of this system to 1024*600? I have try many ways but cannot sucess.

Hi @chongting_Zhao try editing /boot/uEnv.txt and force the resolution 1024 600… There is an example in that file, just be sure to remove the “#” and use your resolution.
