The TV and computer monitors have a lot in common. They both come in HD displays, and their function, price, and size can often overlap. Even with limiting differences between them, they are still distinct from one another.

Refer to the table below:

What we have been trying to tell you is that both monitors are similar, but not essentially the same. And then, you must also consider the cost and the features that come at that price. Although with technological advancements, even laptops are becoming as expensive as TVs, sometimes we find it hard to even compare.

Turning Monitor to TV

Your computer monitor must have some specific modern capabilities for you to convert your monitor to a tv.

Can You Turn Your Monitor to TV?

Ask yourself the following questions to determine if you can turn your monitor to the TV:

  1. Is there an HDMI input, a DisplayPort connection, or a VGA connector on your computer?
  2. Does it have a built-in speaker or an audio jack?
  3. Does your computer support a minimum resolution of 720p?

If the answer to all these questions is yes, then you can easily convert your Monitor to a TV screen.

How to Use Your Monitor as a TV

With monitors that come with HDMI ports, it is simple to convert them into a TV screen. However, older monitors rarely have HDMI ports. In such cases, you can use the VGA converter instead.

To use a VGA converter, your media source must have an HDMI input. This adapter will also help you with the sound by allowing you to plug the soundbar right into it. This could be especially helpful if you are not happy with the built-in speaker of your computer.

Now, to attach a cable or antenna signal, you will need a TV tuner that will decode the signals and transform them into a picture. TVs usually come with a TV tuner while computers don’t come with one.

Hooking a Cable Box

Hooking a cable box to a monitor is easy. Plug one end of the cable to the HDMI port of your cable box and the other end to your computer monitor. It is as easy as that. If you don’t have an HDMI port on your computer, you can also use the HDMI to VGA converter.

If your system has an HDMI input but no audio, you will need HDMI Audio Extractor. Your HDMI cord from your cable box will go directly into the extractors. Then plug the HDMI cable from the extractor into your monitor for the video signal.

If you have an AV input, you can use the AV cables to connect the tuner to your computer.

There are various ways of using the monitor as a TV. Of course, you will need some extra hardware, which some of you might find to be a bit of a hassle.
