Hello all,
I had a similar issue on my HP EliteBook 9470m (Windows 8.1 Enterprise) and I admit it was very annoying. I recently downloaded the latest version of the driver for my Graphic card: Intel Iris and Graphic driver for Windows 7 / 8 / 8.1 version 15.33.22.64.3621 released on 21th May 2014.
Now it works like a charm.
I hope this will help you
