“Portable monitors are mainly aimed at business travelers looking for enhanced productivity while on the road,” notes Paul Gagnon, vice president and industry advisor on consumer technology at research firm The NPD Group. “But they can also have utility for hybrid workers or students not looking to invest in a dedicated home office setup for space or financial reasons.”

Portable monitors typically come in sizes that pair well with laptop computers (mostly from 14 to 17 inches) and typically offer a baseline resolution of 1080p. The larger you go in screen size or the more screens you add, the heavier your remote work setup. Some monitors stand apart with 2K or 4K resolution—like our best overall pick, the SideTrack Solo 4K.

No matter which style of portable monitor you choose, these handy devices can help you do more in less space. To guide you in your search, we’ve done the testing and research to narrow down the best portable monitors available right now.

Australian start-up Espresso Displays’ eponymous V2 model comes in 13- and 15.6-inch versions with a touchscreen, along with a 13-inch version without touch. Espresso’s prices are a bit more than some competitors, but all models share the same stylish design aesthetic, plus a bevy of features other portable monitors don’t have. Take the 15.6-inch touchscreen portable monitor, for example. It has a brushed aluminum and glass chassis and a super-slim (0.2-inch) design, with a 16:10 aspect ratio display and two USB Type-C ports. The maximum screen brightness is 300 nits.

Other optional accessories include a choice of stands, the coolest one being the espressoStand, a $69 foldable magnetic stand for mounting the monitor for vertical or horizontal viewing. The optional stand is height adjustable, but folds flat. Last but not least, this pick is versatile. The Espresso comes with its own software, called Duet, allowing you to use the touchscreen on both MacBook and PC laptops.

  • Slim design
  • Magnetic attachment on back for a stand
  • 1080p resolution touchscreen

Cons:

  • Stand and stylus not included

How We Chose The Best Portable Monitors

We combined research with hands-on testing and experience, and we spoke with product experts and industry leaders to help us determine the products that make the cut. We carefully evaluated each portable monitor’s resolution, size, weight, refresh rate, price and more. These selections take into consideration what sets each monitor apart from its competition.

How To Choose A Portable Monitor

Portable monitors are small, compact and lightweight screens designed to expand the on-screen real estate available to run your favorite applications. A portable monitor makes multitasking on a laptop computer much easier and more efficient.

Most portable monitors rely on your laptop computer’s battery power to function—requiring just one cable to link it with your computer. Some portable monitors have their own built-in rechargeable battery. All are easy to transport and can likely fit within your existing laptop case, briefcase, or carry-on bag.

Let’s look at some of the key features to look for when choosing a portable monitor to best fit your needs.

Resolution, Maximum Brightness And Refresh Rate

In the case of portable monitor, the higher the better with regards to resolution, maximum brightness and refresh rate. Resolution describes the visual dimensions of the display and is based on width and height. It’s determined by how many pixels are used to create the image you see displayed. For example, a 1080p monitor has 1,920 x 1,080 pixels. The 1,920 is the number of pixels across, while the 1,080 refers to the number of pixels in height. Altogether, a 1080p monitor uses 2,073,600 pixels. For reference, a 4K monitor uses four times the number of pixels as a 1080p monitor.

At minimum, look for a portable monitor with a 1080p screen. If you can afford it, go with a 2K or 4K monitor to see more detail and vibrant colors.

Maximum brightness, which is measured in nits, directly affects color perception and power consumption. The brighter the display, the more easily you can see the screen in a brightly lit area. A higher brightness also means the monitor requires more power to operate. Most portable monitors that rely on power from a laptop computer offer a lower maximum brightness than a monitor with its own power source, especially when it’s plugged into an electrical outlet (as opposed to using its own battery).

On the plus side, a lower brightness tends is easier on your eyes, but a higher brightness (more nits) provides more luminescence and makes it easier to view the display in bright ambient light. A typical portable monitor has a maximum brightness between 200 and 600 nits.

A monitor’s refresh rate is the number of times per second that whatever you’re viewing on the screen refreshes. When a monitor offers a 60Hz refresh rate, it refreshes the screen 60 times every second. A 120Hz refresh rate refreshes the screen 120 times per second, which makes it better for gaming or watching fast-moving action on the display. In a nutshell, refresh rate directly relates to how smooth animated graphics or video content look on the display.

Size And Weight

Consider the overall size and weight of the monitor, especially if you expect to carry it along with your computer when on the road. Smaller screen sizes are lighter than larger ones, by nature. An attached monitor may make sense, so you can carry everything as one unit.

As a secondary monitor used for multitasking, you may find a smaller size display can accommodate your work habits and need for extra portability. Meanwhile, if your work requires photo editing, writing, drawing or annotating, choosing a second monitor with a touchscreen display and higher resolution will be beneficial.

How It’s Powered

Most portable monitors rely on your laptop’s power, unless it comes with its own built-in rechargeable battery. Some monitors have a second USB Type-C port through which you can attach your own power source. If you’re using a monitor powered by your computer, expect your laptop’s battery charge to run low faster. And the monitor will drain power faster still if offers 4K resolution, since higher resolution displays typically require more power. Power is one reason brightness often suffers on a portable monitor.

Built-In Speakers

While some portable monitors have two tiny, low-powered speakers built-in, chances are the speakers built into your computer offer higher-quality audio. For the best audio experience, consider using Bluetooth headphones or wireless earbuds with noise cancellation, as opposed to relying on the audio that some of these portable monitors can generate. Check out our picks for the best wireless headphones and earbuds.

Price

In general, larger displays cost more. Higher resolution and faster refresh rates also add to the price of a portable monitor. Well-known brand names—like ViewSonic, ASUS, Lenovo or Dell—often carry a premium over some of the generic models you can find at Amazon and other e-tailers.

Operating System Compatibility

All non-touchscreen portable monitors can work with a MacOS or Windows-based computer. While models can also work with other operating systems, such as ChromeOS or Linux, so double check the specs if you want to use the monitor with any of these operating systems.

Touchscreen portable monitors are sometimes trickier. All have Windows support, but only some support additional operating systems—including MacOS, ChromeOS and Android. If you want to use the monitor with a MacBook, look specifically for monitors with a dedicated driver or software to enable touch. ViewSonic, Espresso and SideTrak all come with some variation of Mac software.

Use your Apple iPad as a second screen for your MacBook or iMac thanks to the SideCar feature.

Apple

If you’re a MacBook (or iMac) user and have an iPad tablet, the latest MacOS and iPadOS operating systems have a Sidecar feature, so you can use your iPad tablet as a second monitor for your computer—either with or without a cable.

How Big Is A Portable Monitor?

The best portable monitors come in a wide range of sizes. The size you choose is a matter of personal preference and should be based on your work habits and needs, as well as how much you want to spend.

Some portable monitors are extremely compact and provide an extra 12- to 14-inch display, although it’s more common for a portable monitor to offer at least a 15.6-inch display. A few displays go up to just over 17 inches. Displays larger still are more cumbersome to travel with and typically need to plug into an electrical outlet to function, making them less portable and more like a small desktop monitor.

Most portable monitors are less than 0.5 inches thick, and the monitors themselves weigh less than two pounds. Most come with a travel case or cover—making them very easy to transport with your laptop computer. Of course, this varies based on the screen size and model you choose.

If you’ll be using a portable monitor with your laptop computer, for the best experience, choose a monitor size that’s about the same as your laptop’s display and then position the two monitors side-by-side at the same height. If you’re using a three display portable monitor setup, or a specialty portable monitor, this suggestion does not apply.

Can You Connect A Desktop PC To A Portable Monitor?

Yes. Portable monitors typically include some cables, such as a USB Type-C to USB Type-C cable, a Mini-HDMI to HDMI cable and a USB Type-C to USB Type-A cable. As soon as you plug a portable monitor into your computer, Windows or MacOS identifies it as a display and it should work immediately. In some cases, however, you may need to download a free driver or adjust the System Display Settings (Windows) or Display System Preferences (Mac) on your computer for the portable monitor to function properly.

Do Portable Monitors Work With Any Laptop Computer?

With the proper drivers installed, almost any portable monitor will work with almost any Windows PC or MacBook laptop computer. For the best user experience, position the additional monitor directly to the side of your laptop computer’s existing monitor, making sure they’re both at the same height. Or, choose a vertical portrait orientation, so you can see a document in a longer length, just as you can on a tablet.

Are Portable Monitors Worth It?

It all comes down to what you use your computer for, whether being able to multitask is important to you and how much physical space you have to set up your equipment on a desk or flat surface.
