Hi, I have a LG34UM65 monitor, connected to my GTX670 via a DVI-D dual link cable. I'm running at the recommended 2560x1080 resolution (Windows 7-64 bit). Graphics card drivers are up to date. However, I cannot seem to play any Bluray content (Powerdvd 10/fully updated) or any HD content on Flickster/UV. The sound is perfect, but image wise, all I get is a grey screen with millions of tiny dots. Any ideas? Thanks
