'ZDNET Recommends': What exactly does it mean?

ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.

When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.

ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards.

Computer monitors can come with some pretty steep price tags, especially if you're in the market for a specialized screen for PC gaming or creative work like animation or video editing. This is doubly true if you want a high-end OLED display, a 4K monitor, or a super-sized screen.

There's a way around this, however. If you're looking for a cheap solution, you can easily connect your TV to a laptop or PC to use as your main screen, a part of your current multi-monitor setup, or as an emergency backup monitor. Depending on how you want to connect your TV to your computer, you might not have to spend any money at all.

I've put together a short walkthrough for setting up your TV as a monitor on Windows, Mac, ChromeOS, or Linux as either a temporary solution or a more permanent addition to your setup.

The quickest and simplest way to connect your PC to your TV is by connecting them with a regular HDMI cable and selecting the correct input in your menu settings. Once everything is set up and powered on, you'll have an almost perfect mirror of your desktop on your TV.

If your PC or laptop uses Thunderbolt or DisplayPort for connecting external displays, you'll have to pick up a USB-C-to-HDMI or a DisplayPort-to-HDMI adapter. They're around $10-15, but keep in mind that since the TV still relies on HDMI, you won't get the same high-speed data transfers as you would with a monitor that has a DisplayPort or Thunderbolt connection.
