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!

    Thanks a lot for trying out and reporting back. Will wait till end of month when 2004 is officially released and see how it goes.

    Cheers.

    No worries. Definitely good success here. 

    Nice to get to the bottom of it. 

    I'm just left wondering when 2004 is deployed or whether they can just release those 2 firmware's now separately.

    Good to hear that. Are you using Surface Dock as well?

    Cheers.

    Yes - Surface Dock connected to one external 2560x1440 monitor.

    So far so good with these latest updates.

    I also had this problem when using a USB-C to HDMI cable and USB-C to Satechi HDMI/USB HUB. 

    When I'm happy the Surface Dock is working without any issues today, I'll also go back and try those devices too.

    JD, 

    Are those the Dell U2415 monitors you have? As far as I can see on dell.com, I don't see a model 2415H.

    If you are using the U2415 monitor, you can browse through the U2415 User Guide and on page 27, it should show you what you need to do.

    I hope it works for you.

    Ethan,

    I have a similar setup except I have two 2415H monitors and the January updates broke the second output reaolution output. 

    I spent a lot of time in February /Early March trying to get it to work and just gave up very frustrated and using only one monitor. 

    How do you “enable Displayport 1.2” on the 2415H?

    Thanks,

    JD
