Hdmi Video Output

I work for Dell's Social Media Team. If you are connecting the laptop to a TV using HDMI cable, Open the "display settings" in your computer and activate output to the TV screen. You can either mirror content of your computer on the TV or extend the display just like a dual monitor screen.
On your TV remote switch to "External Inputs" from the menu. You will need to change the default "Video 1" to a different selection which may be "HDMI 1" or "HDMI 2" depending on how you have them connected.

Important: Make sure you connect the cable to the TV before turning on the computer as sometimes it may fail to recognize external display.
You may also need to change the screen resolution of your TV using the Display settings in your Control Panel else the picture may appear distorted.

Thank you.
