If your computing needs require a larger-than-normal screen, using your television is a great way to maximize your viewing area. Whether you are making detailed Excel spreadsheets or watching videos on YouTube, using a TV as a monitor definitely has its benefits, and is worth the effort required.
Find out what kind of input connections your TV has. Do this by looking at the back of the television screen and examining the different ports. They should be labeled according to type: S-Video, Composite, HDMI and Component.
Determine what kind of outputs your computer has. The goal here is to find a match between your computer and TV. For instance, if each have an HDMI input/output port, then you can use an HDMI cable to connect them.
Get the appropriate cables. If you were not able to find a match in the last step, you will need to find an adapter to make the different inputs work together. For instance, if your TV only accepts component cables, and you have an S-Video output on your computer, you will need an S-Video component adapter.
Plug the cable into the appropriate ports and then boot up the computer. Once you turn on the television, you should see a clear picture of your computer's display.
If your image flickers, then your input/output does not match. This generally happens if you take a high-end digital signal and try to channel it into analog composite cables. Luckily, if you have an LG flat screen TV, you should have S-Video, Composite or HDMI inputs, which will resolve the flickering issue.
