DisplayPort Problem

Recommended Posts

Hi guys,

I'm having issues with my displayport. recently installed SwitchResX and accidentally selected the wrong resolution for my monitor. Right after my monitor went blank and shows "input not supported"

After following instruction from SwitchResX by deleted monitor profiles, the problem still persist.

Strangely, when I connect an HDMI cable to my GPU, I'm able to login pass the apple logo. (unable to do this using displayport)

I've tried various things and nothing seems to work even in safe mode.

I've attached my bootlog.txt for your reference and also video link. Would appreciate some help.

GPU: Sapphire Nitro+ RX580 8GB

Monitor: Acer ED273

OS: Mojave 10.14.1
