If you don’t have a digital projector but would still like to show off your project off your computer, as long as your TV has the correct inputs, you’ll be able to transfer the video signal from your computer to your TV. Computer monitors connect to your computer via an RGB port (red, green, blue). Modern computers have this port colored blue. You can buy RGB cable needed connect to your computer and then to your TV at most electronic stores. If your computer has a better video card, you might have HD outputs that can connect to your TV for a better picture.
