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 installed 25.20.100.7101 however this did not solve my problem.

    Not sure what else to do.. I have the exact same issue:  I migrated from Surface 4 to Surface 7.  Dock worked fine wiht Surface 4.  With Surface 7 the monitors flickers a bit but doesnt show anything on them.

    I also updated the Dock firmware, but that didnt help.

    All in all its a mess..  I hope to be able to use my 2 monitor set up with the dock soon..

    Thought I'd post to see if anyone found any solution.  I'm very frustrated as my now 3 month old SP7 won't output two or even one external monitors like it did before I updated in early February.  Everything worked great until the update.

    So, last night I went through a two hour chat and Log Me In session with Microsoft support.  All they did were all the same steps I tried through all the different suggestions I was able to find on my own. Delete display and try different driver, delete monitors and reload drivers, update dock firmware, blah, blah blah.  

    Without a solution I was told by Microsoft it was a compatibility issue and now I should do the Fresh Start and reload everything.  What a solution.

    Anyway, I tried and that failed too.  Stopping after a few minutes saying unable to complete or something similar.

    FYI, I aslo have a SP2017 (5) that connecting to the same dock can get one monitor at full resolution and the other stuck at 640x480.  This Surface worked well to up until the update.  Oh yeah and it's not the dock cause I have a second dock and I get same results. It does have a different version of the video card, Intel Iris Plus 640 but same problem.  

    Anyway misery loves company and I just needed to vent.  I guess my next step is to do a complete restore and see where it takes me.  I really am not interested in wasting my time but not sure what else is left other than trying to return for a new machine. 

    Thanks for listening.

    I share your pain.  

    Microsoft have been appalling handling this issue.  In true IT fashion they assume it is all your fault and you must have done something to **** it up.  With so many reporting the same issue it is annoying this issue is not even acknowledged.

    The only way I have been able to resolve it (after trying all the things you did) was to purchase a AUD$30 USB-C to HDMI cable which I now connect from my SF7 to my widescreen monitor (QWHD).  

    Resolved the resolution issue. TICK

    Quality is not as good a Display Port connection

    Downside is that I now have two cables connected to my SP7 (dock and USB-C).  The whole point of a dock - even one as connectivity challenged as the Surface Dock - is to avoid this sort of set up.

    Will it be fixed? Perhaps.  However my recommendation to any one interested in a SP7 is "do not buy".

    I should say my Surface Go doesn't suffer this issue.
