PC Specs:
Asus P8P67 Pro
i7-2600k
Sapphire Pulse RX 580

I tried multiple ways to fix black screen issue, but unable to fix it. I am accessing display using Remote Desktop.

I really don't know what to do.

Attached my ioreg and EFI.

This is the log from WhateverGreen.

After trying multiple ways, now I was able to fix the black screen issue by using the adapter HDMI to Display Port.
