Display to TV using HDMI cable

[DaveG480]

I use my laptop in a classroom setting and want to send images from the computer to a big screen TV. PowerPoint presentations work fine (as long as I am in Slide Show mode), but I cannot get anything else onto the TV. I know there is a setting somewhere that I cannot find. Help would be very much appreciated.

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

• Click Start, Control Panel, Appearance and Personalization.
• Choose 'Connect an external display' from the Display menu.
• What's shown on your main screen will be duplicated on the second display.
• Select 'Extend these displays' from the 'Multiple displays' drop-down menu to expand your desktop across both monitors

Computers and TVs have a wide variety of video connection types. The video connection on your computer must match the connection on your TV or monitor.

1. Select a connection type based on your second monitor.

   • Monitor: VGA  or DVI  cable

   • TV: Video (composite)  or S-video  cable

   • High Definition TV: DVI  or HDMI  cable

2. Connect the TV or monitor to the computer using the cable you chose.

3. Connect a power cable to the TV or monitor, and then turn it on.

4. TV connections only: Change the TV video input source to match the video source connection from the computer (Line-1, Video-1, HDMI, etc.). Refer to documents that came with the TV for instructions.

   Depending on the TV, the image quality might not be as good as that of a monitor.

5. Turn on the computer.
