5700 XT second monitor no longer detected by Windows

I've had the 5700 XT since September, and while trying to deal with the continuous random black screen issues that plagued the previous drivers, I thought I'd try one of the features of my motherboard that allows you to have one monitor connected to the GPU and another connected to the onboard graphics, in hopes of getting rid of it.


So I enabled the setting in the bios, connected the second monitor to the onboard graphics through HDMI and all was well. Until now.


When I tried to revert back to having both monitors connected to the GPU, the second monitor is not detected by windows at all no matter what I try. 



Things I've tried: 


Tried to boot with just one screen connected through HDMI


Tried 19.12.X drivers


Clean 20.1.3 driver install


Reseated GPU and RAM


Different HDMI cables


Switched ports between the Main Monitor(DP) and Secondary Monitor(HDMI). So Main Monitor was connected through HDMI and Secondary Monitor was connected through DP. Same issue. Now Main Monitor(HDMI) is not detected.


Reset BIOS settings (in case I had changed something else other than the dual-monitor-specifc setting and had forgotten about it.)


Turned HDCP support off


Fiddled with most of the Radeon settings to no avail.


Is there something I'm missing that could be software related? Or is my HDMI port fried? To me, at this stage, it seems like the HDMI port is a goner, but I just don't understand how since last time I used it was a 2 months ago and it was working fine.


I'm completely stumped. Any help would be appreciated.
