may try older or newer driver , some drivers can cause a black screen under some games and / conditions . then port issues like display port not working are kinda common on 900 series
may also look in to them games on having black screen issues ?
Far cry 5, seemzs to had issue and maybe a patch ?

seems like GTA was ''buggie'' as well
thig is it works all through that furmark ? try mark3d firestrike as well and see . to me abnd I could be wrong if a port issue it would do it no matter not just this or that [opinion]
good luck
''Auto means the card is running off the default vbios fan curve built into the card. Doesn't sound like a overheating issue to me'' I agree with sajin 70c is comfortable at full running load over time used on air
check your driver feed back threads like this latest someone stated [dang all ready 27 pages ?? ]
''Please fix gta 5 godrays!
Gta 5 godrays are missing when enabling any kind of msaa(2x,4x...)
Driver 388.71 was the last driver without this issue. So the issue is caused by drivers and not the game itself
but the best true one from that thread
''In my opinion get rid of the crap called Win10 go back to a solid non invasive, non spying operating system that always works with every nVidia driver (It's called Win7.)''
