since i update the driver package on my two Pcs i cant use 4K/60 Hz anymore... I changed nothing only update the Driver!
My main PC is an AMD System with an Asus RX560 4GB Graphic card, connectet with DP on a LG 27UD58-B 4K Monitor which support DP 1.2 and HDMI 2.0,
second PC is an HP Pavillion with an AMD A10-9700 with R7 onboard Graphic (HDMI) connected to an other LG 27UD58-B.
on HDMI i have artefacts and Black Screens sometimes and on DP the DP LInk set to a lower bandwith that allow only 4K on 30Hz. I try different Cables (4K ready) but not work..
also i try change the sytems but not work too... I think that would be unusally that two systems had the same Problem... the only change was the drive update... reinstall windows no success too.
can someone help me?
Please try updating to Crimson 17.9.2.
