Thanks,
I'm using the HP 3005PR with a Samsung Display Port monitor with 2560 x 1440 resolution. Dell XPS-12 I5, Intel 4000 Graphics

I installed the update, and have verified that DRM video is working (Netflix, XBOX video etc.)
However, the display on the Display Port monitor is so choppy that it is almost unusable. With the 7.1 drivers, the external video wasn't as perfect as the direct connection DP from the laptop, but it was acceptable.
With the 7.2 it is unacceptable
