So i've been having an issue regarding RX 5600 XT XFX THIXX III Pro, I would play modern Warfare no OC(OverClock) or UC(UnderClock) just normal standard gaming mode. Anyways It would turn off my monitor and tell me no hdmi input.
My Computer would still running just refusing to go back on the monitor,
thought it was the following:
PSU
HDMI CABLE tried 3
CPU
Motherboard and such i tested all of it and did all the updates for them including this magnificent Beast of a GPU.
after a few evenings after work i found the problem,
It is too fudging BIG i saw that the GPU sags a bit so i took a few lego and built a Brace for it to push it up.
Comes down to the card being too heavy and gravity pulling it down legitly the reason i was struggling, it just made a half a mm not contact with my motherboard that is all So try it if you think this might be your problem
or try running your card vertical with the force of natural gravity
