Using a TV screen as your monitor makes working on a laptop computer a lot easier, especially if you happen to have a newer-model TV that is bigger and has a better display capacity. This can be handy if showing photos to a room of people on a screen larger than your laptop.
Turn off both the TV and laptop, if they are in use.

Locate the VGA cable that you will use to connect the laptop and the TV.
Find the RGB/VGA external monitor port on your laptop. It is usually found at the back or on the side. It will have 15 pins (five holes in three rows) and, in most models, has a screw hole on either side.
Attach one end of the cable to the external monitor port of your laptop.
Connect the other end of the cable to the VGA port at the back of your TV.
Tighten the two screw-in connectors to secure the cable.
Turn on the TV.
Use the remote control to switch the TV input to PC, AUX or HDMI VIDEO, depending on your connection.
Turn on your computer. Adjust the screen resolution both on the laptop and on the TV until you're satisfied with the picture quality.
