It feeds.. your soul :)

Did you had any previous manufacturer's software version? Like the ATI Catalyst CC for AMD Video Cards, or NVidia's CPanel. If so, try uninstalling them before installing the latest sw from the official site. That did the trick for me on a HD radeon 6500

I had the same problem with a desktop PC last Sunday. The PC was already equipped with a working W10 installation, just after the install of the "fall creators update" the video resolution dropped from 1600*900 to 1024*768. Solution was: - uninstalling the video card from the device manager (marking the "delete software driver" option) - download and reinstall the official sw from the video card manufacturer's site Same problem occurred on my personal home PC, after the "falling" update, my Sound Blaster audio card stopped working :( I suppose the new W10 update is messing around with drivers in general..
