No signal on my TV when I connect the laptop via HDMI

HP Recommended
Pavilion Laptop
Microsoft Windows 10 (64-bit)

I have a cs3067 laptop with Windows 10 Home.  When I connect the HDMI cable to my TV it says no signal.  When I use the same cable from a different laptop or tablet it works fine.


I have updated Windows and all drivers to the latest version without success,

Thank you for posting on 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:  

Step 1: Connect the second display

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.

note:If your PC only has DVI and your TV does not have a DVI port, you can use a special adapter or converter cable.
  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.

If you have problems connecting a TV to the computer, consider the following.

  • Turn on the TV before turning on the computer.

  • Use only one video source per display device. Do not connect two cables to the same TV or monitor unless it supports picture-in-picture.

  • Make sure your TV supports sound with your connection type, or use a separate audio cable connection.

  • If the computer cannot detect the TV, set the TV as the primary display device, and then restart the computer.

  • Make sure your TV input source matches the video source that you are using. On the TV remote control, press the Source or Input button.Input 1, HDMI 1, or S-video or similar displays, depending on your TV. If your TV does not have this option, you cannot use it as a second monitor without using special video signal processing (not covered in this document). For more information, refer to the manual for your TV.

  • If you are using a coaxial or S-video connector, set the desktop screen resolution to 800 x 600 (or less).

  • Adjust the aspect ratio to scale the image to the screen you are using.

  • Make sure the signal format of the TV matches the signal output of the card (for on-board TV-output, this setting can be changed in the BIOS). For standard analog signals, a TV accepts either a PAL (Europe) or NTSC (North America) signal.

Hope this helps! Keep me posted for further assistance.
