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!

    We have had to give up on the Surface docks for any users who have large format monitors.

    We now use the DELL WD19 USB-C docks, which work perfectly. The issue isn't necessarily the surface, its the dock.

    Today MS pushed another graphics driver update for SP7 (27.20.100.9621)

    And it broke the external monitor setup again.

    And lo, this thread is still here.

    Abandoned.

    Mr Panay, is this how your team treat your customers?

    Created a Microsoft ticket on the 9th of June 2021 because of the 640x480 resolution problem with 24(!) Surface Pro 7 devices & Surface Dock 1 setups.

    I said that the resolution is OK with an old HP E243 24" monitor with DisplayPort but only 640x480 with my HP E27q G4.

    After 2 months of mail conversation & phone calls I receveid the following answer today:

    My name is ****** and I am the new Microsoft Support agent who will be handling your case from now on.

    As far as my understanding goes, multiple troubleshooting steps have been applied without any improvement in the behavior of the external monitor connected to your Surface device via Dock 1 and Mini Display to Display Port cables.

    Moreover, according to the case notes, this issue only occurs with HP E27q G4 external monitors, and the connections work as intended with other monitor brands. Since the troubleshooting steps that ensure the Surface devices work fine have already been performed, my suggestion is to open a support ticket with HP, as we suspect there might be a compatibility issue between the two types of devices.

    Looks like they realy don't want to help on this matter.

    Realy disappointed in Microsoft and will never ever buy this **** anymore from them.

    Spent nearly the whole working day trying to sort out this issue. I eventually had to roll back the display driver on my SL3 to 25.20.100.7101, and swap around my displayport connections several times until they came alive and in the correct resolution.

    I have one 34" monitor on 3440 x 1440 and one older monitor 22" on 1680 x 1050. Both at max resolution now.

    I'd be satisfied with that resolution. I am still running only one monitor on my two monitor stand. When I need the two monitors, I switch back to my Surface Pro 5.
