Confirm Operating Mode is Single Display and Digital Television is the Display Selection. Click Apply and check the screen for the TV display.
Note: For newer drivers confirm that Television is selected from the Display drowpdown menu.
If the above steps do not resolve the TV-out problem, try each of the following suggestions:
Reseat both ends of the TV cable.
Use a replacement TV cable. In most cases, you want to use a TV cable with the same kind of connectors as your computer's TV-output port's connector. For example, an RCA-to-VGA cable is not supported. An S-video-to-S-video cable is supported if your computer has an S-Video output port.
If your computer does not have a TV-out port but has a VGA port, TV-out may or may not be supported by your computer. Check with your computer manufacturer whether a TV-out port can be added using an add-in card (for desktop computer), a special adapter cable, or a docking station (for laptop computer).
If you are using an external monitor, shut down and power off the computer, unplug the monitor, leave the TV connected, and then power on the computer.
Try reducing the desktop screen resolution to 1024x768 or below.
Check if the computer's system BIOS Setup menu has a setting to enable TV-out during bootup.
Update the computer's system BIOS. Check with the computer or motherboard manufacturer if a newer system BIOS update is available and for instructions on applying the update.
Update to the latest version of the Intel graphics driver.
