AMD ryzen 5 3400g with readon vega 11 integrated video max resolution 800x600
Hello everybody, recently i assembled my first PC and i decided to go for the AMD ryzen 5 3400g with the integrated readon vega 11, the problem is that even after installing all the video drivers the video quality doesn't improve that much and the resolution can't be modified from 800x600, even more when i first turn on the PC the monitor start flickering for few seconds, i tried to uninstall and reinstall all the video driver and i even tried with several different monitors but the problem persist.
I really don't know how to solve, please help me.
