Many laptops use a VGA port to connect to other computer monitors. With this connection, laptops can use a computer monitor as an additional laptop screen. If you want to use a HDMI television screen as an additional monitor, you need to convert the VGA signal to an HDMI signal.
This process is simple as long as you have the correct equipment, which includes a VGA to HDMI adaptor cable.
Connect the VGA end of the VGA-to-HDMI adaptor cable to the VGA port on the laptop.
Connect the HDMI end of the cable to the HDMI port on the back of the television.
Adjust the settings on the display properties window. Among the settings to adjust are the visual resolution of the television, and whether the television will serve as an extension of the laptop.
Turn the television on. Change the television channel to the HDMI setting to ensure that the television is receiving the signal from the laptop.
