How to Play YouTube Video Files on TV

By James Ford

The easiest way to watch YouTube videos on a TV is to connect an Internet-ready computer to it. The latest TVs come with multiple inputs meaning that many external devices such as computer consoles, DVD players and computers can all be connected at the same time.

Things You'll Need

  • Internet-ready computer
  • Television
  • Appropriate cable

Step 1

Unplug both computer and TV.

Step 2

Look at the back of your TV and your computer and determine which types of video connections they have. In order to connect your computer to a TV, both the computer and the TV must have the same connection. For example, if both TV and computer have an S-Video socket, you can use an S-Video connection. For diagrams of the connections available see the "Resources" section below and for a brief overview of connections see the "Tips" section.

Step 3

Get an appropriate cable, such as an S-Video cable, from your local audio, video or electronics store.

Step 4

Insert the corresponding cable into the computer and the TV.

Step 5

Switch on the computer and TV.

Step 6

Open your computer's control panel, click on "Display" and open "Display Properties." Click "Settings" and then "Advanced."

Step 7

Click the "TV" tab and then click on the "Enable output to TV" or "Output Device: TV" and click "OK." The computer screen should go blank and the output will appear on the TV. You can now open the Internet browser, go to and watch the videos through the TV.

Tips & Warnings

  • S-Video connections and composite/component video ports are the easiest and cheapest connection type and are found on older computers and standard-definition televisions.
  • Other connections include VGA and DVI, with newer models coming with HDMI support. The advantages of a HDMI connection are that it can support high-definition visuals with audio through a single cord. Other connections may require you to connect the sound from the computer to the audio input of the TV separately.
  • If your computer and TV don't share the same cable connection then it is possible to buy an adapter or cable to convert between connection types. So, for example, you can convert a DVI to a HDMI interface.
  • Try to avoid having cables running across the floor to avoid trips or falls.
