RE: Adrenaline -- all the drivers have worked properly until 18.4.1, then the problems started appearing and getting worse with every driver past that. 18.3.4 were the last drivers that did not exhibit this issue. I can, and have, clean installed 18.3.4 and a few others before that (i've deleted them since) without any problems, but no amount of clean installing 18.4.1 or above makes them "monitor stable" for me, so it seems to be something they've been changing since 18.4.1. Also, I should update my info -- I have an RX580 now and not the 290x. My RX580 has Hynix memory. As of right now, I'm stuck on 18.5.2. VSR does not work for me any longer (screen blanking on any VSR resolution BUT the highest) but native works. 18.6.1 and above, even native resolution has the screen blanking every 1-2 seconds. Thanks for the info, though.
