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!

    Same here, external monitor stopped working after the recent updates.

    Works fine with other non-SP7 devices.

    Cleaned the display cache, no go.

    Tried removing the monitor in Device Manager, updating the monitor driver, still the same.

    And yes, dock firmware is latest.

    Cheers.

    I am also having this same problem. I am using USB-C -> Displayport on my Surface Laptop 3 Intel edition to display two external monitors via MST daisy chaining.

    When I have the both monitors powered on, they become Digital Flat Panel (640x480 60Hz) in device manager and I get no display from either. However, if I turn the second display off, it detects the correct "Dell U2414H(DisplayPort) from the primary and I am able to get a desktop display "

    This worked fine until the Firmware and Drivers update this weekend. (January 2020 edition)
