Adding an external monitor to you work from home setup can boost your productivity when you’re at your work desk, but what about when you leave the house or office for a business trip, or want to work in a public place like a library?

Portable monitors have been around for a few years, but the technology has finally gotten good enough that we can finally recommend them to just about anyone looking to take a display with them on the go. We’ve done some research, and gotten hands-on testing with portable monitors, and they’ve worked far better than we expected.

The displays are ultra thin — fit-in-a-backpack-pocket thin — and light enough to carry anywhere. It’s possible to power them by connecting them to a computer without plugging them into an outlet, although their maximum brightness may be lower in that configuration.

The only snag we experienced was that you have to plug them into your computer with the included USB-C to USB-C cable, you can’t swap them out with another one.

If you’re starting to work outside of your home, or want to add an ultra-thin external display to your work from home setup, a portable monitor may be the right choice.

What Are the Best Portable Monitors?

There are many factors to consider when choosing the best Portable Monitor for you; below are the most important ones, which we considered while we were researching this list.

Screen Size: All of the portable monitors in this guide have a 15.6-inch display, which is the equivalent of carrying around an additional laptop-sized screen around.

Screen Resolution: All of our external monitor recommendations have an HD (1920 X 1080) resolution or higher, so text, photos, and videos will look very sharp.

Inputs: Commonly known as ports, inputs are what allow you to connect them to your computer, phone, tablet, or game console. All of the monitors in this guide have either a USB-C or USB 3.0 port. Both are capable of supplying enough electricity to power the monitor, and can transfer data quickly enough for the display to work reliably.

Compatibility: Every monitor below can work with both a PC or Mac without any additional software. The portable monitors with USB-C can also be used with the Nintendo Switch for a better gaming experience while you’re on the road.

1. Innocn External Computer Monitor

Best Overall
Innocn External Computer Monitor


We’ve had the chance to try a few portable monitors, but after putting it through its paces, Innocn’s is the clear winner.

The 15.6-inch monitor has a resolution of 1080P, and its screen was glossy, so colors appeared very clearl. Many of the portable monitors had a matte display, which reduced the amount of glare, but made everything look a little muted. By comparison Innocn’s portable display looked crisp and clean the entire time.

What really sets this portable monitor apart is its design. Most portable monitors come with a detachable case, which needs to be folded in a particular way to stay put. Innocn’s monitor has a base that functions as its stand, giving you 180-degrees of motion. In our experience, the Innocn’s monitor held its position at all angles.

This monitor’s controls are located on the left side, while its ports: Two USB-C, one Mini HDMI, and a headphone jack, flank the left side. The monitor’s ports functioned perfectly, and its buttons were far more comfortable to press than the ones we’ve been used to using. Another positive surprise was this monitor’s overall build quality. It feels more solid than any portable monitor we’ve tested so far.

If we could only recommend one portable monitor, it’d be this one from Innocn. It performed very well during every test we threw at it without any problems, which has earned it the top spot in our guide.

2. AOC I1659FWUX

Budget Pick


Aoc’s portable monitor has a high resolution display, built-in kickstand, and is VESA mount compatible while retaining a more budget-friendly price.

This portable monitor has a 15.6-inch 1080P IPS display, and connects to your computer via a USB 3.0 cable. This is the only port on the device, and can supply both power and data. Aoc says the display can be used in portrait and landscape mode, and its kickstand will accommodate both configuration.

This portable monitor can be attached to a VESA mount, like Mount-It!’s Single Monitor Desk Mount, which allows you to position it precisely where you want it. You can use a VESA mount while on your desk, and remove it from the display when you’re on the go.

If you’d like a portable monitor with physical flexibility, but aren’t quite sure if this type of gadget is right for you, Aoc has you covered.

3. Uperfect 4K Computer Monitor

Premium Pick
UPERFECT 4K Computer Monitor


If you regularly work with high-resolution video or photos, Uperfect’s 4K Computer Monitor is the best choice.

It has a 15.6-inch display with a 4K resolution, which means it has twice as many pixels as a Full HD monitor. Everything you view will look incredibly clear, which is necessary if you’re looking for subtle details in an image while deciding whether to make any changes. UPERFECT’s portable monitor also supports 100% of the sRGB spectrum, so colors will look incredibly accurate.

The portable monitor has a USB-C PD (power delivery) port, USB-C port, Mini DP (DisplayPort), headphone jack, and full-sized HDMI port on one side, and an additional USB-C port on the other end. The display has a detachable kickstand, so you can use it vertically or horizontally, and is VESA mount compatible.

This is definitely a deluxe portable monitor, and some of its features are overkill for common tasks like writing or web browsing. If you work with high resolution media, though, you’ll definitely appreciate the bump in resolution and color accuracy.

If you’re a creative who spends a lot of time on the road, or traveling from shoot to shoot, UPERFECT’s 4K Computer Monitor is the external display you should get.
