Hello I just got the GPU said above and I have hooked it up to my TV in the lounge, a 46" Panasonic Viera and had some problems with the resolution but managed to sort that out. The other problem I have is that it flickers almost like it screen tears or something, the refresh rate is at 60hz so I'm confused. I normally use a monitor (Dell U2412M to be precise) however it's getting replaced so I am still awaiting to receive that back, until then I can determine if it's the GPU or TV, I have a GTX 570 which I am currently using and it is connect via HDMI to my TV and no problems what so ever. I hope it's not the GPU as I just got it and can't tell if it's the TV or not. I used HDMI as well to connect the 670.
