I just got a hdtv today and I wanna hook my computer to it with vga to vga. But it says that theres no signal. Please help.Your TV is saying there is no signal I assume. This is normal, especially with a brand new HDTV. Sometimes what you have to do is change the order in which you turn the devices on. I WOULD turn everything off. Shut down your PC. Plug the VGA into the TV, making SURE it is secure at both ends. Turn the TV on. Turn the PC on and give it a minute. I've gone through this every time i've purchased a new HDTV, no MATTER what i'm hooking it up to. PS3, PC, DVD Surround, etc.

Also, after you get a signal and can see your desktop, you'll PROBABLY have to change the display resolution on your PC.

One more thing... You might want to actually unplug your TV from the wall outlet. Then plug it back in before you connect the VGA to it. Then turn it on.You might also think about getting a new video card with a HDMI output.Quote from: rthompson80819 on January 26, 2010, 02:15:20 PM
