ATI Radeon setting under Ubuntu, but how to do it

Question asked by buth45 on Aug 25, 2019

Hello, everybody, 


I have a new computer

The computer: Mainboard: Gigabyte X570 AORUS ULTRA (

CPU: AMD Ryzen 5 3600 6-Core Processor

GPU: ATI Radeon RX 5700

lshw -c display

Here's the problem.

The image from the screen is overdriven, or in other words, the contrast of the screen is too high. 

How can I adjust or influence the screen output for AMD ATI Radeon?

Under nvidia there is the software "nvidia-settings", is there something similar for AMD ATI Radeon? 


Many greetings
