P2416D, DDM stopped working after Surface update

Few weeks ago, DDM stopped working after an update. I have two Dell P2416D monitors and although both are recognised and shown in the Device Manager, whenever I load DDM it just states "please connect a Dell supported monitor". I've made sure I have the latest drivers and the most recent DDM version. I've uninstalled it a few times but still not working...grrr

I have a Windows 10 Pro Surface x64 bit OS, i78650U CPU

Re: P2416D, DDM stopped working after Surface update

This is an Intel gfx driver error. You will need to either rollback the current driver or wait for Intel to fix the issue with a future driver release.

The latest 26.20.100.7870 Intel mobile gfx driver here and dated 2/19/2020 works directly to single and daisy-chained monitors, but you may have trouble installing it on your Surface Pro and it may not work with the dock (I don't know).
