Sorry about my english.
I noticed that after the new Adrenalin 18.12.2 drivers installation, my sim rigs 1080p 144 Hz 3-monitor set up can only be used in 60Hz mode. With previous driver everything was working fine. 3 monitors are same brand and model connected with DP (Vega 56). I can only choose 144Hz if I use very low resolution settings. I can use all 3 monitor separately 144Hz ( other 2 unplugged then)
Second thing: I have 4th monitor (1440p HDMI 2.0) that I have to unplug physically when I am using 3-monitor set up and vice versa (annoying). Is there possibility in Eyefinity settings to choose which monitor is in use or maybe get option for that?
