Why can't I switch the display to TV screen?

Applicable Products and Categories of This Article

When I start my computer and connect the video output connector of my computer to a TV set with a cable and try to switch display with the hotkey ([Fn] + [F8]), I cannot display images/texts on the TV screen. The video output is unexecutable. Why is this so?

Due to the specification of your computer, you will not be able to switch display.
To display data on the TV screen, connect the cable before you turn on your computer. You can also switch display by restarting your computer.

For your information, the video output of your computer is done at the resolution of 640 x 480 (VGA).
If you select a higher resolution than that, it becomes the virtual display.

You may refer to the Troubleshooting section of the operation manual as well as the online manual for more details.
