Can A Monitor Replace Your TV?

Monitor Replace Your TV

Anyone with a monitor in their garage gathering dust has probably thought: “Why can’t I just use this to watch TV?” Well , you can! As more people move to mobile devices or upgrade their screens when replacing their computer, there are usable and decent monitors taking up room in storage cabinets everywhere. Before you toss your old monitor to the landfill, consider repurposing it.


You don’t need a computer for the monitor to work; it can connect to a cable or satellite receiver, tuner box or movie player using the same inputs as a standard TV. A decently sized LCD monitor (24”-32”) can make a great option for that spare bedroom. Repurposing it will save you money and a trip to the local recycling plant (monitors contain toxic chemicals so they must be properly disposed of). Even an old CRT or flat-panel monitor can be converted to receive TV signal; the age and quality of the monitor just may make the modification cost-prohibitive for the picture quality (see below for tuner box cost).

When you do go shopping for a new monitor – considering making sure you can use as a TV in the future. Make sure to look for one that supports HDMI input. If you want to be able to watch HD content received over-the-air or Blu-Ray, make sure it’s HDCP Compliant. High Definition Content Protection is like the DRM encoded into digital music. High definition video content has similar protocols to deter piracy and your screen needs to be capable of decoding the content protection for you to be able to view it on a monitor.

Satellite/cable receiver boxes act as tuners, receiving signal, decoding HD content protections, putting video in a format that your monitor can process and sending audio to your home theater. Users without a satellite or cable box will need an external TV tuner box in order to change channels – look for one that includes a remote control. A TV tuner box also sends audio to external speakers or your home theater system and offers additional connection options if your monitor’s inputs don’t match your cable, satellite, antennae or DVD player’s output.

There are two basic types of TV tuner boxes on the market: digital and analog. Check the connections available on your monitor because that determines the type you need. If you have an older CRT monitor or don’t intend to watch HD content, check out Sabrent’s Stand Alone TV Tuner (about $35). It supports a VGA connection (which older monitors require) and is fairly easy to install.

If you have a newer monitor that is HDCP Compliant with HDMI input but don’t have a cable or satellite tuner box, consider the Channel Master CM-7001 HDTV Antenna and Cable Tuner (about $130). Those who live in an area that broadcasts HD channels over-air may even save some money on cable or satellite by using the built-in HDTV antenna.

There are several ways to connect a TV tuner box to the video output from your cable, satellite, DVD player or antennae, in descending order of preference: HDMI (if available), S-Video connection, composite video or RF coaxial cable. You could plug the raw feed from your analog cable TV or antennae directly into the RF coaxial input on the TV tuner, but you likely won’t receive as many channels. Most TV tuner boxes allow you to connect to multiple sources, so you could connect to a source for TV, a source for movies (DVD or BluRay), and perhaps a game console.
