Hello good people,
My old DVI-connected monitor was working fine. The 4K I just got shows no signal via DP and no signal or a purple hue (depending on the port) via HDMI.
Someone on the forum had luck by disabling CSM in BIOS. That didn't help in my case. Worse, I can't even get back into BIOS anymore!
Screen is black where before I had the gigabyte logo, "press F..." prompt, and later clover options. It only comes to life at the os login.
Pressing delete or F2 might be getting me into bios because the boot is interrupted, and I don't get to the os login, but I can't be sure because the screen stays black.
How can I get back into BIOS to re-enable CSM?
(and, any ideas how I can then get my new monitor to work via DP?)
