By now you probably know that I’m all about getting the most value out of electronics. TVs are great, but they can be a pricey one trick pony. And then there’s the quandary of what to do with that totally functional computer monitor after you migrate to a laptop or tablet.

How about using that monitor to watch your favorite TV shows, stream movies and media? Good news! You can do a lot more with a monitor than simply connect it to a computer.

monitors as tv

If you’re purchasing a monitor and want to make sure you’ll be able to watch TV or stream content to it, there are a few factors to look for:

  1. Make sure it supports HDMI input
  2. Look for one with integrated speakers or an audio out jack. Otherwise you’ll need an adapter for sound.
  3. Confirm its HDCP Compliant. This is so that it can decode the HDCP protections imbedded in HD content by distributors in an effort to protect the content from piracy.

If you want to stream TV or movies on your monitor, sans computer

For readers with a relatively new monitor, it might be as easy as investing $30 in a Google Chromecast. The Chromecast will allow you to stream whatever subscription services you utilize (such as Netflix, Hulu or HBO Now) as well as access music, sports and YouTube through thousands of apps supported by the Chromecast device.

The recent addition of Chromecast compatible services like Sling TV and DirecTV Now will let you stream cable stations like TNT, Animal Planet and HGTV to your Chromecast for $20 or more a month, depending on service tier and provider.

HDMI compatible monitor with built-in speakers

This one should be pretty much plug & play. Plug the Chromecast into your monitor, power on the monitor and use your Smartphone or other mobile device to set up the Chromecast. Once its connected you can use your Smartphone or tablet as a remote.

HDMI compatible monitor with no audio

While the video should play on your screen, you’ll have to try a work around to get audio.

Option 1: Invest in an Audio Extractor

Adapters such as this Links HDMI to HDMI + 3.5mm Audio Extractor ($25)

Option 2: Screencast from your phone to a Chromecast attached to your monitor.

Attach a portable speaker to your phone or connect your phone to a compatible home theater system with an Aux cable.

Note of caution: there may be lag between audio and video using this method. Try using screencast with audio running on your phone before you invest time or money in this option.

Monitors with DVI or VGA inputs only

Note that Chromecast doesn’t work with many older monitors. Keep your receipt so you can return the Chromecast and adapter if your older monitor doesn’t recognize the Chromecast input.


You can attempt to set up a Chromecast using an HDMI to DVI converter with Audio out, such as this adapter from TNP Products. However, it’s important to note that many users have reported that the Chromecast doesn’t work on devices without a high enough screen resolution (at least 720p).

A few troubleshooting tips:

• Make sure your monitor’s input is set to the port in which you’ve plugged in the Chromecast
• Getting a blue screen with “HDCP unauthorized. Content disabled” error? Your monitor won’t be able to stream HD content using a Chromecast or any other HD input device.
• Casting from your device often only sends the video with no audio. Instead, run apps such as Netflix and Hulu on the Chromecast, not your phone or tablet.

If you want to watch local broadcast TV on your monitor

To watch local broadcast TV on a monitor, or a television for that matter, you need either a cable or satellite TV subscription or an antennae and a TV tuner box.

You can connect most satellite or cable receiver boxes to a monitor and – assuming the monitor doesn’t have integrated speakers – a set of external speakers. You may need an adapter if your monitor’s input doesn’t match your receiver box’s available outputs.

If you’re looking to “cut the cord” like so many readers out there, you may still be able to access local broadcasts using an antenna. That’s right, just like the “rabbit ears” of old, the modern-day antenna has a wider range and looks a bit sleeker.

TV reception using an antenna depends on your broadcast area, the broadcast signal strength, obstructions, etc. If you live far outside of a city with a broadcast tower, you may not be able to get network reception without satellite. Check out AntennaWeb to get an idea which channels you should be able to access at your location with an antenna.

You can get an indoor HDTV Antenna with a 35-mile range for about $18-20 on Amazon. A 35-mile range should work great for city dwellers. Here’s one by 1 By One that most in-town users found to fit their needs.

If you live further outside of a metropolitan area, you may need a wider range (50 or 75 miles) which may require an outdoor antenna. Here’s an inexpensive option, also by 1 By One, that offers an 80 mile range for $30.

In order for your monitor to recognize and play the content received via antenna, you’ll need to get a TV tuner box to act as a bridge between your monitor and your antenna. The tuner box that’s right for you depends on the inputs and outputs of your monitor and antenna. Make sure that you get a tuner box that offers a sound output if your monitor lacks integrated speakers.
