XP sp 3 NVIDIA GeForce 6600 GT which has (1) AVG output and (1) DVI output Trying to display over a Samsung LCD tv with HDMI port, am cabled per the tv instructions So far only showing PC as the Source and a comment that says "check cable" on the tv I checked in Display and there are ony 2 options #1 is "Plug n Play Monitor" #2 is "Default Monitor" Has no effect to change from #1 to #2 or turning off the regular monitor. Do I need updated / different drivers, or? I would think being the NVIDIA has the DVI port, it should send signal thru that. I would hope I could display over the tv without unhooking the VGA cable every time. (Haven't tried that yet, will after this post) It would be convenient if I could display over both simultaneously, as the tv is in another room and it would be nice to be able to start the movie over the pc using the regular monitor to set things up and get it started. Thanks for any help!
