After I've installed new optional ver of drivers (Adrenalin 2019 Edition 19.8.1) I get some problem:
After few minutes/hours/secs I get blank, black, screen and messages for screen - no signal.
I use DP, never had problem like that before.
I cleaned all amd drivers and programs (watt man, ryzen master, chipset driver, gpu driver) and install old version - Adrenalin 2019 Edition 19.5.2
Now every is OK like it was so something wrong with a new one...
