I'm having a problem with my XFX RX 480 connecting to my projector (Nebula Solar Portable) over the HDMI port when running Windows 10 when it worked perfectly before.
I've verified that the ports on either end work perfectly and I've swapped out the cables to be sure. The projector works fine with a Win10(S) laptop, Fire Stick 4K and Raspberry Pi. The GPU connects just fine to my main monitor over the HDMI port.
The projector simply isn't seen at all in Win10 (in Display Settings, Device Manager or Adrenalin) despite the BIOS showing up just fine. I assume it's some kind of handshake issue but I have no idea how to reset or force them to see each other? I tried rolling back the GPU drivers to no avail so I'm back on 21.6.1
Hope someone can help!
