I got the same problem with external screen and new driver. Such a pain…. so I rollback driver.
I don’t know why every new intel driver are crap on TR series.
Anyway, older driver seems ok for the games I am playing such as Warcraft III…..
Hope things change with intel drivers one day.
By the way if you make a search on the forum, you will see that the Zoom button issue and the BSOD with external monitor with new driver have already been discuss without much success to find a solution.
