HP 24uh 24-inch LED Backlit Monitor
Microsoft Windows 11

My HP 24uh LED-backlit monitor decided not to display blue. In other words, the display only shows reds and greens. 

 

I have an HP Z2 G4 workstation. And an HP 24f monitor as a second display (which has no issues). The GPU is a Radeon Pro WX 4100 with four mini-display ports. I use adapters to connect the monitors to the mini-display ports. 

 

The drivers are all updated. As is Win 11. I've checked the hardware as well as I can. I've moved the cables to different ports, I've switched the adapters, I've switched the cables. But throughout all those changes, the 24f monitor works and the 24uh does not. Previous to this week, changing to a different port has brought the 24uh back to normal, which is odd. But then it "de-blues" the next day or two. 

 

Can the monitor be saved, or is it toast? Let me know if you need more info. Help sent my way would be very much appreciated. Thanks!
