With just a few steps, you can turn an old computer into a new TV. This will save you money and reduce electricity consumption.

- Install the TV signal
Set up hardware to receive a TV signal on your computer screen. This can be done with a variety of devices. Your choice will depend on how much you are willing to spend and the quality of your computer. You can choose between a TV tuner card (with or without a graphics card, depending on the capabilities of your computer) and an external TV tuner box. A TV tuner card must be installed by a professional, but it provides a clear connection to TV channels. An external TV tuner box can be easily installed by plugging it into USB port , but the connection is slower and provides a lower resolution image.
