Turn Your TV Into a Free Computer Monitor and Save Big
Why buy an expensive monitor when your TV can do the job?
Computer monitors can be pricey, especially high-end ones for gaming or creative work. But ZDNET explains a simple workaround: use your TV as your computer screen. The easiest method is to plug an HDMI cable from your laptop into your TV, then switch the TV to the right input. That's it — you get an instant large monitor, ideal for spreadsheets, movies, or giving presentations.
If your computer doesn't have an HDMI port, you can buy a USB-C-to-HDMI or DisplayPort-to-HDMI adapter for about $10–15. This works with Windows, Mac, and Linux. The only downside? You won't get the fastest data speed for gaming, but for everyday tasks it's fine.
Want to skip cables entirely? Most smart TVs support wireless mirroring through Apple AirPlay or Googlecast. That's convenient, but ZDNET warns you may see noticeable lag or fuzzy resolution. For anything that requires quick reactions — like typing or gaming — a cable is better.
There's also a remote PC option for newer Samsung and LG TVs, letting you access your computer over the network. It's more advanced but can turn an old TV into a true workstation. Overall, this trick can save you hundreds of dollars and breathe new life into an old TV.
- Connecting a TV and laptop with an HDMI cable is free if you already have one — no special gear needed.
- Wireless casting is easy but can feel laggy; a cable gives a sharper, faster experience.
- If your laptop lacks HDMI, a $10–15 adapter usually solves the problem on any major operating system.
