Windows 10: Windows 11 detects but will not display a third monitor

I have three monitors Samsung Odyssey 28in 4K running off of RTX 4080. All of the monitors work independently. However, Windows will only display to two at a time. When a third one is plugged in, it will detect the monitor and a small icon signifying the port will pop on the monitor screen for a moment. In the System > Display window the monitor will appear as a small box labeled "3". This "3" box is unable to have the desktop extended to it the 'keep these display settings' prompt appears but nothing changes and can not be rearranged like the larger "1" and "2" boxes can. 1 I have resta

Windows 11 Upgrade from Windows 11 Preview Causes Inability to Detect 2nd Monitor

Hello,

Upon upgrading my Acer Inspire PC from Windows 11 Preview to Windows 11 today, I can only use one monitor. Steps I've taken:

1. Swapped "monitor to pc" cables and verified both are functioning normally.
   
2. SYSTEM | DISPLAY | Scale & Layout | Detect Multiple displays > results in "We didn't detect another display"
   
3. Device Manager | Display Adapters | Lists "Microsoft Basic Display Adapter", however, the PC's invoice says "Intel UHD Graphics 630"
   
   • Intel's Driver & Assistant App shows all drivers are up to date, but it too shows the "Microsoft Basic Display Adapter"
     
   • Downloaded "Intel(R) Graphics Driver: 30.0.100.9928" software from Intel - it failed to run, saying "no driver, CODE 8"
     
4. Device Manager | Display Adapters | Microsoft Basic Display Adapter | Tried both "Update Driver" options > no change.
   
5. Device Manager | Display Adapters | Microsoft Basic Display Adapter | Uninstall Device, then restarted > no change.
   
6. Verified no updates were needed.
   
7. Powered off and back on.
   

Any ideas?

Many thanks!

Windows won't detect by second display.

I have my monitor and TV connected to my GPU. In Display Settings, under Rearrange your displays I have the 2nd highlighted. Clicking the Detect button will render: Code:
