How to Connect a Computer to a TV with HDMI Inputby Stan Kane
You can connect a computer to a TV using a HDMI cable if both devices have compatible ports. High-Definition Multimedia Interface (HDMI) input ports are found on HDTVs and most computers. Other types of video cables that connect a computer to a TV include S-Video, Video Graphics Array (VGA) and Digital Video Interface (DVI). Verify that your computer has a HDMI output port and that your HDTV has a HDMI input port by consulting your owner's manual.
Turn off your laptop or desktop computer.
Disconnect the monitor from your desktop computer. Laptops are exempt from this step.
Move the computer close enough to the television for the HDMI cable to connect the TV and computer.
Connect the HDMI video cable to the HDMI output port on your computer.
Attach the other end of the video cable to the HDMI input port on your HDTV.
Turn back on the computer and verify the television is on, with HDMI input selected. Your computer's screen should now be displayed on the TV.
