Using DVI here, RX 570 4GB if it matters. If the PC is put to sleep, whenever a key is pressed to wake up, the screen turns into TV like static White noise. Unplugging and replugging the monitor (DVI) seems the only way to make it work again. Updated to Windows 10 1903 and the behavior is the same. Tried a couple of different VBIOSes, still the same. For those of you who make like such a problem doesn't exist: Google the terms "AMD won't wake up from sleep" "AMD monitor wake up snow" etc. etc. and you'll find thousands of forum posts where people shared their experiences of having the same issue, and it dates back to half a decade ago. Such problems made a lot of people switch camps, and when you look at the market share for GPUs, it is like that for a reason. AMD had an epidemic of R9 290/290X cards randomly displaying black screen and not waking up from sleep (probably an issue that existed for the HD 7000 series of cards too) and taking almost a year to partially solve the issue back then, there's also the UVD bug for the HD 7000 series of cards but my HD 7950 passed away so that no longer bothers me, but just goes to show how "competent" AMD's Radeon group is.
