If your graphic card was manufactured in 2007 and newer, try uninstalling the xserver-xorg-video-intel package and use the builtin modesetting driver ( xserver-xorg-core) instead. Installation of the proprietary "AMDGPU-PRO" graphics drivers published by AMD (Unsupported, generally poorer quality, and can cause instability with later system updates. Installation of the free AMD/ATI graphics drivers (Recommended, typically the fastest and most stable, with full OpenGL and Vulkan support) Technical words can be used but explained. Also make sure that the appropriate firmware packages are up to date. If you get a fixed low resolution (like 1024 x 768) with no choice of higher resolution in GUI and/or xorg-server log errors with missing device (like (EE) open /dev/dri/Card0 no such file or device) and/or non starting display manager (sddm etc), make sure that your kernel is up to date (as the kernel has to recognize the graphics device).
If you don't know your graphic card, visit hardware identification page to identify it, then find more information on its setup by matching it to one of the pages below. Almost all graphics cards have free and open-source drivers available in Debian, however some cards may have better compatibility and performance after installing proprietary firmware or proprietary drivers. This portal contains links to the various Debian wiki pages regarding graphics cards and their respective driver installation processes.
