I have a desktop computer that I would like to connect to my LCD TV, but there's is no video whenever I attempt to this. I noticed that when i clicked on control panel, volume, is states that the ATI HDMI audio is not plugged in. I have a Gateway AMD Phenom with Windows 7 operating system. Your assistance is greatly appreciated.
If you are using the HDMI to connect to your TV, you must have the driver installed (check device manager), and you must enable it it in Catalyst Control Center - Displays, select the same resolution as your TV (720p, 1080p, etc.).
