PC to TV won't work

[jordan853]

I purchased an HDMI cable to hook up from my desktop to the tv yesterday and it doesnt work. Its windows 7, nvidia geforce gtx460. I have no idea if this is a hardware problem or a driver problem or what. It works on my laptop however (alienware nvidia video card). on the desktop, the tv shows "no signal". the tv is about a year old, samsung 55 inch full 1080p. I was checking around the "multiple displays" setting and nothing i tried worked. However i can drag things into the gap that a second moniter should be, it just doesnt appear on my tv. pleas help thanks,

Have you set up "Setup Multiple Displays" in the Nvidia Control Center? Also, does Windows recognize the second monitor in the Screen Resolution window?

did you go into the TV's control panel and select the HDMI port that the PC is plugged into ?

yes i tried that and there were 2 devices options. the first was my pc moniter, the other said "Enabled VGA connecton" or something but the cord i'm using is HDMI not vga. and windows DOES detect it, it shows up and everything as a monitor.

Yea i tried all that. windows defiantly recognizes it as a moniter. it shows 2 moniters, my actually one, and something about a vga imput which must be wrong because i use an hdmi and i see no way to change it

my tv says something about vga too. but the computer won't work unless i seek out the hdmi port and enable it so i can see the computer screen. forget about looking for vga ( or PC anything ) and look for the hdmi port that you have your cable plugged into.
