How to Connect a Laptop to a TV RGB Cable
Laptop computers are fairly versatile; however, the monitor screen can leave a good deal to be desired. Because of this, laptop computers have either a DVI or VGA video port. This port allows you to connect to larger monitors. It is also possible to connect to a television via RBG cables, also known as component cables. However, before you connect the laptop to the TV you need to decide if you want to view the contents of the TV on your laptop, or watch the contents of your laptop on the TV.
Things You'll Need
- DVI- or VGA-to-component cable
- RGB cables
- Video card
Decide if you want to watch the television on your computer or use the TV as a larger monitor. If you want to view the contents of the TV on your laptop, you need a video card connected to to the computer. These cards can either be inserted through the express PCI card slot on the laptop, or via USB cable. Make sure the video tuner card supports component video.
Connect the DVI-to-component cable into the DVI port if you want to use the TV as a large monitor for your laptop. However, if you have a VGA port, plug the VGA-to-component cable into the VGA port.
Plug the RGB component cables into the component side of the DVI- or VGA-to-component cable. If you want to watch the TV on your computer, insert the RGB cables into the TV video card.
Plug the other end of the RGB component cables into the TV. If you are using the TV as a monitor, plug the cables into the "Component In" ports. However, if you are sending the TV signal to the computer, plug the cables into the "Component Out" port (the other end of the DVI- or VGA-to-component cable that you connected to your computer in Step 2).
Power on the TV. If you are using the TV as a computer monitor, press the "Video" button until "Component Video" appears on the screen. If you are watching TV on your computer, launch the television viewing software that came with the TV tuner card. You can now see the contents of the TV on your computer.
