Re: RMA replacement card has same problem as the one I sent in.
The garbled screen might fix if you turn the monitor off and on again, I used to get that weird thing as well on my 970 from time to time. It's like looking at your monitor through privacy glass or something. Assuming the issue is the same, never figured out why it did it and it only did it when resuming from sleep but turning my monitor off and on always resolved it.
it's a Samsung S22C300 monitor using HDMI
