I'm struggling to connect my 4th monitor to my PC, which has an RX 6600 graphics card. When I plug in the 4th monitor, it switches from saying 'no cable connected' to 'no video input.' I've tested with different cables and monitors, and it seems like the issue is isolated to the bottommost DisplayPort. Despite uninstalling and reinstalling the graphics drivers, Windows only recognizes 3 monitors. Any help would be greatly appreciated!

Have you checked the resolution and refresh rate settings for your other monitors? Sometimes, you don't need to max out all the ports to get the GPU functioning well. Just curious to know if you've tried adjusting them.
Yeah, I've lowered the resolution on the other three monitors to the minimum at 60Hz to see if that would help, and I've rebooted, but I still can't get the 4th monitor to be detected. I thought that if it was the only monitor plugged in that it would work, but no luck there either.
