Method 1. Plugging your PC directly into your TV. You can plug a laptop or smaller PC directly into your TV without having to buy any additional equipment (you might have to buy a cable or two though) as long as you have HDMI on your PC and TV. In order to link them together, you will need a connector (the type is dependent on how new your TV is). If you do not have HDMI, then you may also use VGA with an audio cable – 3.55mm to RCA. If your TV does not have VGA, your computer will need to have a video card that supports component video.
