gigabyte b85m
i5
16gb
rx480 > 65" TV
installed fine, booted fine, but now getting artifacts on the screen, followed by either black screen and or "no signal" from the that point on.
I've tried using both my freshly installed Catalina, old Catalina, install USB, and getting the same results each time. I'm assuming this may be a bios setting, but no idea if it's that or clover, etc or really how to begin figuring out what has broken.
any ideas where to start ?
