Every time computer wakes up, or launch, or close a game in full screen appears 3 or 4 times, a noise test screen during 2 seconds, then normal screen, and go on..

First instalation in windows 10 with windows drivers didn't appear it, but  when I installed oficial AMD drivers problem came.

My setup:

Motherboard: Gigabyte B450M DS3H

Processor: AMD RYZEN 5 3400G

Memory: 16 GB Corsair Vengeance LPX  DDR4 3000 CL16

Monitor: HP w2216v  (VGA input using adaptor DVI>VGA)

OS: Windows 10 Pro

Driver: win10-radeon-software-adrenalin-2020-edition-20.2.1-feb3

I added a similar screen image as i have...

Hope you have all info you need. 

Thank you.

DVI-D to VGA adaptor was the problem. It seems there was no continuous communication between monitor and graphic module, then every time monitor waked up, system try to configure new monitor. Changed to HDMI-VGA adaptor and problem dissapeared.
