It seems that the frequency is actually higher than the 50 Hz reported by Ubuntu in System - Preferences - Screen resolution. When I call up the BIOS of my TFT screen, by pressing the physical button on my TFT screen, it shows that it is running on 60 Hz (which is the ideal frequency).
I have attached the requested files. The problem is not related to Beryl, by the way, as the problem already occurred before I installed Beryl.
