Windows 10: Windows 11 Upgrade from Windows 11 Preview Causes Inability to Detect 2nd Monitor

Hello, Upon upgrading 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", which I don't think is correct - but not sure what the PC came with.4. Device Manager Display Adapters Microsoft Basic Display Adapter Tried both "Update Driver" options > no change. 5. Device Man

2nd screen black after upgrade 12/11/15?

Hi

I have a new AIO plus a 2nd monitor. After the upgrade on 12/11/15 I now have a dual screen display with only half visible, as the 2nd monitor is black. I tried restarting the computer, but made no difference. The only info I am finding suggests having to
reinstall the display driver, which seems rather drastic for a new computer. Any ideas? I work from home and the dual monitor is essential to my work.

 

Windows 8 Upgrade Streamlined to 11 Clicks

For those who upgrade between succeeding versions of Microsoft Windows, the upgrade installer can be cumbersome. There are way too many prompts and clicks. Microsoft is working to make the upgrade package of its next major version of Windows, for now referred to as Windows 8, streamlined to as few as 11 clicks. The new installer will be designed to perform most of its tasks without needing user input.

Microsoft will implement a new web-delivery method, where you purchase your Windows 8 license online, and the installer downloads your soft copy to you. It is pre-fed with your 25-character product key. Microsoft's next major Windows release is slated for 2012.

Windows 10 stopped detecting 2nd monitor

I've restarted the computer (several times), and it's not showing any signs of detecting the 2nd monitor.

Ever since it stopped working, there's only '1' Display option; clicking 'Detect' in Multiple displays results in the message
"Didn't detect another display"; the Device Manager only lists one monitor (screenshot below); and it has stopped allowing me to select other projection modes unless I connect to the 2nd monitor wirelessly.

I'm using an HDMI cable for the 2nd monitor, and have tried both HDMI ports on the monitor unsuccessfully. The monitor models are Dell E2414H and LG 24J4840.
