Got an old monitor lying around collecting dust, or found a super cheap one on Facebook Marketplace? It’s time to put it to good use.

There are many ways you can repurpose an old monitor and turn it into one of your favorite tech gizmos in the house. Thanks to mini PCs, Raspberry Pis, and smart TV sticks, there are plenty of ways to breathe new life into the aging display.

7Use It as a Secondary Monitor

Perhaps the most obvious use of an old monitor is to hook it up to your PC as a secondary monitor. Now that you have a shiny new monitor, it doesn’t mean that you have to get rid of the old one. If it’s not worth all that much on the used market (and if it is, you could sell it and buy two older monitors), then it could make for the perfect secondary display.

If you’ve never used adual-monitor setup, you don’t realize how much you’re missing until you try it. One of the simplest yet most productive ways to take advantage of it is by splitting your Chrome tabs across both screens.

You could dedicate one display to ChatGPT,Notepad, or a productivity tool, while focusing on your main task on the primary monitor. It also helps organize your digital workspace, as the two monitors feel like distinct, dedicated work zones.

Even if you already have two monitors, there’s little reason not to get a third one, assuming you have a large enough desk or can move things around to accommodate it. It’s more screen estate for your browser tabs, Slack, Asana, and other productivity tools if you work from home.

If you’re a gamer, use one monitor for Discord or Spotify and another for Chrome while gaming on your primary screen. Streamers can use it to monitor the stream chat. The options are near-endless!

You can use adual monitor armto add a second monitor while also saving desk space. It can help prevent your monitors from being accidentally tipped over, making it well worth the investment.

If your GPU only has a single HDMI port with multiple DisplayPorts, but the monitor doesn’t have a DisplayPort, or it’s an older VGA or DVI unit, you can easily solve this with an adapter, such as theCableDeconn Multi-Function DisplayPort Adapter. I used an adapter with my old VGA monitor as a secondary display on my PC for nearly five years until it finally kicked the bucket.

CableDeconn Multi-Function DisplayPort Adapter

The CableDeconn Multi-Function DisplayPort Adapter is a 3-in-1 adapter that connects to a DisplayPort on a computer or laptop and turns it into a DVI, HDMI, or VGA signal for a monitor. While it only supports one display at a time, it’s a multi-purpose solution that works with almost any old monitor.

6Transform It Into a Small Media Center

Monitors are more like TVs than you might think. If your monitor hasbuilt-in speakersand an HDMI port, then it’s basically a dumb TV waiting for you to plug in astreaming stickand start binge-watching YouTube and Netflix. It’s the perfect setup for a mini media center in your kitchen, guest room, garage,patio, or home gym. It’s a compact solution for watching content in less-frequented areas of your home.

Even if your monitor doesn’t have built-in speakers, you may still use Bluetooth speakers or headphones for audio, which is totally fine if you’re watching on your own.

If you choose to mount the monitor somewhere in the kitchen, I’d advise against using it for recipes simply becausean old tabletwould do a better job at it. You can still use the monitor to watch content while cooking and follow the recipe on the tablet.

And if speakers are a must, some Android TV boxes include a 3.5mm audio jack. ARaspberry Picould also get the job done if you’re the DIY type. You could hook up anold pair of PC speakersfor a proper (and most importantly, free) home theater experience.

5Convert It Into a Home Surveillance Monitor

What better way to repurpose an old monitor than by using it to monitor your home (pun intended)? Mosthome security camerasprovide an easy way to stream directly to your monitor, saving you from having to open your phone each time you want to check the live feed. you may even use it as a literal baby monitor.

Some units like theAXIS M42 Serieshave an HDMI Output that can stream directly via an HDMI cable, but there are other solutions, too.

For instance, you may combine the monitor with a Raspberry Pi, mini PC, or your current PC to connect to the internet and run a web app likeWyze Live(for Wyze cameras). Alternatively, you can set up your own solution using aself-hosted NVR(network video recorder).

4Repurpose It as a Smart Dashboard

Another cool use for an old monitor is to turn it into a dashboard. Mount the monitor to a wall or place it on a shelf, counter, or desk where it’s easy to glance at, then hook up a Raspberry Pi, Mini PC, or even anold Android phone, and decide what kind of dashboard software you’d like to run.

Ideally, the dashboard would use software that automatically updates without you having to interact with it. Remember, the monitor (probably) doesn’t have a touchscreen, so it’s really more of a display for your clock, calendar, weather, to-do list, and more.

You could even take it a step further by adding a custom wood frame to cover the monitor’s unsightly bezels for a sleeker, more homey look. By the way, this tip also applies to the next use case.

3Turn It Into a Digital Art Display

If you love art and want to show it off, your old monitor is perfect for this. A slideshow of your favorite pieces is a beautiful way to add a touch of modern home décor that looks modern and elegant without spending any real money. Even if it’s an older CRT monitor, it can look amazing with the right combination of vaporwave and cyberpunk wallpapers.

If you’re an artist, this is the perfect solution to showcase your digital pieces in your art studio without any upfront costs. Brownie points if you build a cool custom frame to hide the monitor’s bezels.

To create a digital art gallery, you’re able to use a variety of devices, including any smart TV stick or box that has internal storage and a Gallery app. Load your photos onto it, then simply start the slideshow, and enjoy the view.

As a side note, you’ve probably already seen people use the Gallery app on their smart TVs for this, but I think it’s wasteful. LCD panels slowly wear down their backlights, but OLED screens are even more vulnerable.

With OLEDs, it’s practically a race to uneven brightness caused by uneven wear. If only a few images are used, or the gallery has fixed interface elements, the screen might even suffer fromburn-in. While the backlighting on your old monitor will eventually fail too, the cost is more bearable. In fact, you likely won’t mind having to recycle it when it eventually dies.

2Use It for a Live Social Feed

If you’re a fan ofRSS feeds, you’ll love this one. An old monitor is the perfect device to use for live social feeds (or RSS feeds) that allow you to glance over the screen throughout the day to see what’s new.

Since you probably won’t have a mouse hooked up to the device powering the feed, you can stay in the know by only reading the content without diving too deep into the topics and wasting time. It’s the perfect solution for those of us who spend a little too much time on our phones.

Like with most other solutions from this list, there are many ways to build a social feed. Premium users on X can useX Pro(previously called TweetDeck), but there are far simpler (and free) solutions.

1Use It for a Secondary Gaming Station or Arcade Cabinet

Perhaps one of the coolest ways to use an old monitor is as a gaming station. You can never have too many gaming setups at home, especially if you have kids or frequent gamer visitors. This works particularly well if your monitor is a high refresh rate panel. Simply hook up your laptop or an old PC and enjoy older games with smoother performance than ever before.

If you’re planning to build a retro gaming station, an oldCRT monitorworks even better. It’s the best way to enjoy classic games running via an emulator.

The simplest way to set this up is to find a spot in your home for the monitor, connect a device that can run emulators—such as a Raspberry Pi, mini PC, or an old desktop—or even play games nativelyon your handheld, thenset up RetroArch. Connect a compatible controller, and enjoy gaming on your mini emulator station.

If you’re handy and want to take it a step further, you couldbuild a DIY arcade cabinetusing some plywood. And what controller is better suited for the task than the8BitDo Arcade Stick, which you can hook up to your Raspberry Pi or mini PC so it never needs charging. You could even add a pair of vintage speakers for a really cool custom arcade cabinet. The possibilities are almost endless.

As it turns out, much like with anolder TV, there are many ways to repurpose an old monitor. Monitors are arguably even more practical for DIY projects. Since they’re significantly smaller, it’s easier to find a spot for one in your home, and you don’t even have to wall-mount it, as a monitor arm can achieve much of the same effect.
