Hi Peeps
I just updated my RX6800 to the 21.2.1 driver and I came across the problem on my Panasonic TV display not working. When my PC booted I could see the BIOS and the Windows logo loading screen. But after that there would be no signal detected. After 30 minutes of trouble shooting. I found a setting on the TV. In Setup/HDMI Auto settings. I changed the corresponding HDMI port from mode 2 to mode 1 which fixed my display.
Hope this helps
