Surface Laptop 3 (Intel) issue with DP1.2 monitor after installing January 2020 updates

Just a heads up and if someone from Microsoft sees this maybe talk to the Surface team:

After installing the January 2020 driver and firmware updates for Microsoft Surface Laptop 3 (Intel), my machine detected my external monitor (Dell U2715H) as 640x480.

The connection is made from SL3 -> Lenovo USB-C Dock Gen 2 -> Displayport to Mini Displayport on the Dell U2715h.

The problem went away after I disabled DP1.2 on the Dell Monitor and the screen was detected with its native resolution of 2560x1440 again.

I think this should be added to the known issues on this article if possible: https://support.microsoft.com/en-us/help/4526150/surface-laptop-3-update-history

    Please note your issue seem quite different from the one I experienced.

    I used the 26.20.100.8141 linked by Beaum  previously to resolve the issue I was having. Intel has released 27.20.100.8190, but I haven't tried it as everything is working for me and I'm tired of wasting time Surface display issues.

    Please note I followed Intel's directions for previous driver removal, but have not manually run a Windows update as specified in line 10.

    You can now update your drivers with the Intel driver pack without waiting for Microsoft. I'm testing this now.

    Unlocked drivers: We heard how much our users want the freedom to upgrade their systems to our regularly released generic graphics drivers and enable our latest game enhancements, feature updates, and fixes. As of this release, Intel Graphics DCH drivers are now unlocked to upgrade freely between Computer Manufacturer (OEM) drivers and the Intel generic graphics drivers on Download Center. Simply use the exe and enjoy the update on your 6^th^ Generation Intel Processor platform or higher, and don’t worry about your OEM customizations--they remain intact with each upgrade and the OEMs can maintain customizations separately via Microsoft* Windows Update. Intel Drivers and Support Assistant drivers will also be unlocked starting April 28^th^, 2020.^^See the Release Notes section *^4^for important information about this update.

    I was able to find an old msi package for the surface drivers that included 25.20.100.7101 version. After completely deleting Intel(R) Iris(R) Plus Graphics from device manager and clicking uninstall drivers.. rebooting, then installing the 25.20.100.7101, my external monitors are now working as expected..

    Yes I am having the same issue.

    My SL3 Intel -> USB-C to Displayport on my Dell Monitor is no longer able to display anything nor daisychain via MST capabilities to the 2nd monitor. Once I turn the 2nd monitor off, the primary monitor is at least able to display.

    This was working up until the Jan 2020 firmware/driver updates.
