Hi guys, thanks for you assistance, but I've got it to work now. As i was setting this up for somebody else, it was connected to a monitor which i had laying around, and was connected via the HDMI and a display port cable. Now i have switched it to a proper HDMI monitor/cable it all works.
I have absolutely not idea how this issues are correlated, but hey i am not complaining.
If you guys have an idea why this issue could have been caused by the cable/monitor, i would be delighted to hear it, so i won't make this mistake again.
Cheers.
