Windows 11 update: Failure to detect USB-C monitors

On April 14th, I updated my Windows 11 PCs (Surface Pro 7 and Surface Book 3) to build KB5012592. Since that time, I have tried two different Surface Dock 2s and neither, with either PC, recognizes my monitors via the USB-C ports. Finally, I switched back to the Surface Dock and both PCs recognize my dual monitor setup using HDMI. I am running two Asus 32" ProArt (model: PA329CV) monitors.

This problem materialized on both PCs, for both monitors, immediately upon the Windows 11 update.

I was on the phone with Microsoft, which offered no advice, instead it immediately sent me to Asus. Working with Asus, I upgraded my firmware (I had already done this a couple of months ago, but went along...), Still no dice. I am waiting on Asus Level 2 support to get back to me.

I am not very keen on performing a complete wipe of my machines to reinstall an earlier version of Windows as I tried this on the Surface Pro. I wasn't vigilant and it automatically updated to the W11 build referenced above during the installation process. As such, the reinstallation process didn't solve the problem - the monitors are still not recognized via USB-C.

Has anyone else experienced something similar? Is this a known problem?

    Hi JohnRizzuto,

    Sad to hear the bad news and worst, the previously working monitor stopped working also.

    Before we proceed with rolling back Windows, please try again running the registry file to clear the display cache like before (Solution 6: Troubleshoot connecting Surface to a second screen (microsoft.com)).

    I also found this Firmware file for the monitor which mentions USB-C compatibility enhancement: ProArt Display PA329CV｜Monitors｜ASUS Global. Kindly try downloading the file on the device and install it then see it helps.

    Regarding with rolling back Windows, I'm sure that the Previous version of Windows option in Windows Settings > System > Recovery is not available anymore at this point. So to rollback Windows on the device, we only have the option to do a fresh reinstall of Windows using a Windows 10 Surface Recovery Image (Surface Recovery Image Download (microsoft.com)) which would basically delete everything on the device or we could also try to uninstall some of the updates that were installed last April. To try uninstalling some of the updates, kindly take a screenshot first of the Update history of the device for us to see which updates were installed around April and share it with us here.

    Kind regards,

    Marrion
