Hello Kronborg,
I have been trying to replicate the issue from our side and so far we have not been able to reproduce it. In the meantime, Can you post here also the Graphics Driver report?
This can be found by opening the Intel ® Graphics Control Panel > Options> Information Center> Save.
This report will help us for our investigation. Also, Can you please confirm if issue persists while using another DVI cable? Are you using straight connection (no video adapters)? Are you using single display, Dual Display or extended? Can you please up(Tue, Aug 06, 2013, 09:33:21 AM) the BIOS in your system?
