Hi all.. Today after I updated my surface pro, my monitor is stuck in a 640x480 resolution. Which is no good with a 49 inch Samsung monitor. If I plug in the HDMI, it works, but, resolution is not that good like it was on the Displayport. Any tips or tricks to get it working again? For some reason it shows 'Flat Panel, 640x480' when using display port, but the samsung drivers when using HDMI. 

I am using the surface dock as well. I tried the displayport of the monitor with other computers and it's working fine. Not with surface. Really need help with this one!

    So I upgraded to win 11, and my monitor didn't register at all (SP Pro 7 on Philips 43m6b 4k60Hz).

    The monitor wasn't even recognized in Windows.

    I thought the problem was different, since the symptoms were different, but after spending multiple hours(!) on trying to find the solution, I did a hail Mary and reinstalled the 2019 drivers again.

    This .. eh .. circumvented (I refuse to say fixed) the problem.

    At first it recognised it with 640*480 (which was already progress) but after running the registry script, and a reboot, it showed in 4k.

    Honestly, what does it take, Microsoft, to get this fixed?

    I agree, it is still a problem with Dell Ultrasharp (U2419H) monitors too.

    OK, so Tier 3 support told me it's a problem with LG the monitor maker and asked me to contact them directly for firmware upgrade.

    Googled online and didn't see any available for my model.

    Anyhow, I've submitted a ticket to LG support and see how it goes.

    Cheers.
