So i've been having this issue for a couple months now, I thought I had found a fix but it turned out just to be a band aid fix because the issue is back now and worse than ever.

My PC specs
Asus ROG Strix B450F Mobo
AMD Ryzen 7 2700x
16gb ddr4 3200mhz ram
AMD RX590 8gb Fatboy graphics card
650W psu
Coolermaster masterbox pro 5 case (plenty of fans)

Drivers have all been updated. AMD Radeon 19.7.1 software installed, Direct X 12 is my version.

So the issue in a bit more detail, is both my monitors will turn black, flicker, and then say there is no input. But the sound works just fine and i can tell my inputs are still fine because if im in the open world i can still use my keys and hear my character move. Nothing besides a hard reset with the power button fixes the issue to boot back up either.

Now FFXIV is THE ONLY game i have this issue with. I can play Division 2, Gears 4, Apex, anything I want for hours on end and i get no crashes whatsoever and alot of those games are far more graphically demanding on my PC than XIV is.

Has anyone else had this issue and might know a good fix? Thanks!
