2400G 4k 60hz YCbCr 4:4:4 black screen issue fixed Adrenalin 2020 Edition 19.12.2 WHQL

Question asked by marceldekker on Dec 12, 2019

Since Software Adrenalin 2020 Edition 19.12.2 (WHQL) the flickering issue is

gone. Good work by the developers of AMD.


I have a AMD Ryzen 2400G and use it with onboard VEGA 11 Graphics running at

YCbCr 4:4:4 8bits.

To run my screen in 4k 60Hz resolution it is constantly flickering, after i turned

the screen (Samsung) off and on, and the issue disappeared.

I have a gigabyte a320-s2h motherboard with onboard hdmi class for 1.4/ 2.0b


If anyone has a good explaning for this?
