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!

    I can't believe I opened this ticket over a year ago and nothing so far.. This should be a easy fix. People have even said what it was and corrected actions to fix. Microsoft... Silence... Good lord people please fix this already.

    I think the shame is on Intel. The drivers are directly Intel drivers and they were working fine to December 2019, after that, they stopped working. Have no idea why MS cannot push the partner and force them to fix it. Even if this is hardware issue, whatever, it should be fixed in drivers.

    Partially, the shame on MS as it was not tested enough before it went to the surface driver update. Anyway, even without MS update, you can download new drivers from Intel and have the same issue, so it is somehow orthogonal.

    We've given up on Surface Pro. They are not business grade. They are now cheap plastic toys with a good marketing department. I've exhausted all avenues and given MS copious opportunities to help. Yes, or 7 Pros have improved but even our replacements have a low grade brightness slow flicker that leads me to believe these have a power control issue. 

    Shame because the Hubs are fantastic and so were Surface Pro 3 to 6
