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!

    LG 31MU97Z that worked fine over DisplayPort with the Dock until the firmware update and hasn't worked again since. Same device insertion tone followed by "Digital Flat Panel" in Device Manager that comes and goes.

    It's been 2-month since this happened... Can we have a proper closure?

    Browsing the forum and I see a lot of people are having issues with the dock too, frustrating.

    Cheers.
