The Pros and Cons of Using Portable USB Monitors for Your Laptop

Sometimes we just need more space to work. Your documents, and any comments and revisions they contain, may need space to expand on the screen. Or maybe your cat needs its own little place next to the game you’re streaming. These are small things, but they add up. Well, the good thing about modern technology is that buying a second screen is easy and cheap. Even if you’re on the go with your laptop, USB-powered portable monitors can be a game-changer for work and play for as little as $50. Of course, you can also pay up to $200, $300, or even $500 or more for elaborate multi-panel models with 4K HDR.

If you’re hesitant about investing in a portable USB monitor, we don’t blame you. Besides cost, it takes some effort to integrate a portable monitor into your daily carry and workflow. But there are different ways to think about these panels, and you might be interested to know their pros and cons.

When it comes to computer screens, there are two types of space to consider. There’s the digital space you have with about 1920×1080 extra pixels on the number of inches to work with. There’s also the physical space of the real world, where you have to set up your computer, plug in your monitor, and have enough space for all of that. Those of you who use your laptops on large, open surfaces you know well, you know your spaces, and you know yourself. But for freelancers working in coffee shops, teams on the go who need to move from room to room, and managers carrying their laptops to different meetings, we all know that space can sometimes be at a premium.

Portable monitor warriors face aggravations like small tables, loose cables, nasty side eyes, and derogatory labels (we’re talking about you, booth hogger). There is also a constant anxiety that one drag, trip, or errant shot can be the literal downfall of an entire setup. And on top of all that, you also use a valuable USB-C port on your machine to power and power your portable monitor. Some even require you to use an HDMI port for display and a USB port for power: that’s two cords plugged into two ports! And even if you have a laptop with a long-lasting battery, ditching the wall with an extra monitor can mean running out of power sooner than you’d like.

Thanks to the humble smartphone, touch typing has now become the primary way many people interact with computers. You may have seen people trying to press buttons on a public information screen, only to discover that it’s just a boring display. Despite this popularity, only about a quarter of Best Buy laptops sold in summer 2026 had touchscreens. It’s not like it’s a particularly expensive feature to implement: Chromebooks have touchscreens and each only costs $500. That said, for many people there’s simply no need to have a touchscreen laptop, and that can be a bit of a shame.

If you prefer that tactile experience, there are portable monitors that can fill that gap. Most products in the $100-$200 range are from brands you probably don’t know about, but they are the cheapest way to add a decent-sized interactive canvas to your mobile computing setup. Hell, you can even get a stylus and draw up a storm if you want, although that experience might not be as fun as with a dedicated drawing tablet.

If you have money to spend, your choices for portable USB monitors get a little crazy. You can add two screens stacked on top of each other. You can add two screens as “wings” around your laptop. You can even flank your setup with three screens if you wish. These options cost between $200 and $1,000, and despite their lack of grace, they offer experiences unique to their respective form factors.

On the other hand, if you have a Windows machine, you can use something like Microsoft’s Mixed Reality Link app to pair a device like the Meta Quest 3 VR headset to your computer to save tons of virtual space for moving around your Slack threads, YouTube videos, and Excel sheets. Meta’s entry-level “Quest 3S” variant starts at $350.

Mac users can extend their screens with an iPad and Apple’s Sidecar feature. Or, for those looking for a new laptop, consider one of Asus’ dual-screen Duo laptops or Lenovo’s bifold Yoga Book 9i.

You don’t need to buy new devices to get extra screen space. It’s relatively easy to build one yourself from old parts and a few modifications. There is a reason for this.

You’ll find that many portable monitors tend to be sized to laptop screen dimensions: 15.6 inches, 16 inches, 17.3 inches, etc. As with many complex electronic products, popular products with long support times will often have their components available to repair shops, warranties or even direct-to-consumer retailers and displays are, indeed, such a component. This means that accessory makers down the line have the opportunity to acquire a large quantity of these displays, install I/O, enclosures and firmware, and then turn them into portable USB monitors.

Now you can buy a 15.6-inch 1080p LCD monitor for $60 and call it a day. But if you’re looking for a nice use for your old electronics, like an old laptop in a drawer, you can rip out its screen and do what Arzopa, Mobile Pixels, and other portable display makers are doing. Tons of people have posted their own DIY conversions on YouTube and you can do it for even less than $50.

I can personally attest to seeing a few brave souls go all out to pursue a desktop-like experience outside of the office and home. The big change at the heart of all this is moving from a laptop to a mini PC. Sure, you lose the built-in screen, keyboard, and trackpad, but you’re also not limited to the component combinations dictated by a manufacturer for a laptop. It’s partly this freedom and variability that makes desktop computing so interesting.

In terms of cost and value, mini PCs with a newer processor will outperform a laptop with similar specifications. A brand new Beelink SER10 MAX featuring AMD’s Ryzen AI 9 HX 470, 32GB of RAM, and 1TB of storage has an MSRP of almost $1,700 (with a pre-sale price of $1,349), which may seem like a steal next to Asus’ Zenbook S16 at $2,300. Be careful, that extra thousand dollars can get you one of those triple-sided portable monitors. That said, the older the stock, the more likely you are to find better deals on laptops rather than mini PCs after factoring in those additional accessory purchases, of which a portable battery pack to charge your laptop could be one of them.
