Did you select the VGA input in your TV as the video/sound connection? It is the same as having a DVD player connected. You have to select the proper input in order to view anything.

I bought a 25' vga cable with sound connections. I plugged it into the DVI pigtail and connected it to my HD TV through the vga/sound connection. No picture on TV. When I went to SysPref and clicked Display there is NO auto detect for the TV> Was told this was a simple plug and view ... HELP!!! Thanks!
