So I recently got a 5700 XT Gaming X but didn't have any display output. I managed to solve this by remoting into windows and installing drivers, but you shouldn't have to remote into windows for that.
Now, the issue is when I turn on my computer, I can't see it post or see the bios as I have no display signal. There's also no image when in safe mode. I only see an image once Windows loads so I'm assuming that I need the drivers installed to have an image, but obviously the drivers wont load before windows, so I can't see my bios. I have tried both HDMI and DP.
