Gigabyte Geforce GTX 660 ti (GV-N66TWF2-2GD) No signal on monitor: Benq G2420HD

Hi Everyone,

System Details

Motherboard: Gigabyte Z77X-D3H
Motherboard Bios Version: F16, Date: 10/24/2012
CPU: Intel Core i7 3770K
Monitor: Benq G2420HD
Cable: HDMI
Drivers at Fault: 320.00 and above
Drivers confirmed that work: 314.22
Operating Systems Tested that have the same fault: Windows 8 64bit, Windows 8.1 64bit, Windows 7 32bit

Details: As soon as I update to any 320.00 Drivers or above including the latest: 331.82 and 331.90 Beta (I believe that was the one don't quote me on it) The Benq Monitor displays as No Signal for HDMI, I have tried doing a clean install on all 3 operating systems with no luck, but as soon as I reinstall 314.22 Drivers everything works fine, the monitor displays again and it's all good.

Does anyone have any ideas of why this could be, how to fix it and if anyone else has had the same issue I would very much like to hear about it?

Cheers,
Steven.
