How to Connect a Laptop to an LCD TV Using HDMI

Updated July 20, 2017

Many newer laptop computers are designed with an HDMI connector for connecting the computer to an external display device, such as a projector or a flat screen television. HDMI stands for "high definition media interface;" it is able to carry both a digital high definition video signal and an audio signal simultaneously over a single cable. When a laptop is connected to an LCD TV with an HDMI cable, the laptop display is expandable to the TV.

  1. Boot the laptop computer.

  2. Connect one end of the HDMI cable to the HDMI connector on the computer.

  3. Connect the other end of the HDMI cable to the HDMI input on the TV.

  4. Power on the TV, and select the correct HDMI input.

  5. Hold the Windows logo key and press the "P" key twice. If this is not the display mode intended, hold the Windows logo key and press the "P" key three or four times -- until the desired display mode is reached.

  6. Tip

    Available modes are extended, mirrored and laptop disabled. Extended mode makes the laptop display and the TV appear as two separate screens. Mirrored makes the laptop and TV display the same image. Laptop disabled turns off the laptop screen and only enables the TV.
