Hello. I'm really lost at this one. Being on Gigabyte tech support phone and email and had the card replaced once. But the issue persists. Few weeks back I had GTX270 on the very same Windows 7 Home Premium. I have a BenQ 2412HD connected via DVI and a Sony Bravia TV via DVI>HDMI (TV's HDMI). It all worked just fine. Then the 270 died. Changed for a 5750HD and all started to not work. When plugged the TV as I did before with the previous card, TV wasn't detected. After a few changes of drivers, searching for online solutions, etc, I got tired and went to return the VGA. So instead of an ATI I've got this GTX460. Same procedures, same fail. No TV. Latest drivers (260.99), new cables (golden, Samsung and other know brand can't remember now), etc. No TV. So I just plugged the TV on the monitor connector, and there it was, the TV was working, so cables ruled out. Connected the monitor (PC turned off) and when restarted, no monitor but just TV. Tried HDMI connection with monitor and TV but that didn't work either. Tired of that, went to the store and got the card changed considering that maybe the ports were bad due to TV and Monitor only working on the DVI 1 port (the one next to the motherboard). New card, same issue, TV not being detected on the DVI 2 port nor the HDMI port. New drivers, old drivers (the ones that can only use are 2xx, 19x don't work) I'm really lost here. Windows "screen resolution" setting (left click on desktop) does say "another display not detected on GTX460" but settings on that are grayed out. On nVidia control panel I try to set up multiple monitors but TV is not detected, upon Rigorous display detection it does nothing, the Force television detection option becomes grayed out so that doesn't work either, I can't force detection on restart because I can't click on it. These are my specs: Windows 7 Home Premium 64bit. i7 930 on a P6T SE 6Gb ram (Kingston) Drivers: 260.99 I really don't know what else to do. Thanks for any help.
