While monitors have been technically “portable” for decades, lightweight models that fit into a carry case rather than a station wagon are a more recent invention. Versions that you’d actually want to use? They’re very new indeed.

While the benefits of a second screen are undeniable, we’ve largely ignored portable monitors on this site in the past. They were just too expensive, had mediocre displays, didn’t work particularly well, and were still too big and heavy to really want to take outside the house with you.

That’s all changed in the last couple of years, as screen technology got lighter, USB-C got rid of the bulky cables and chargers, and competition drove the price down. Several companies are now making portable monitors worth owning, with sizes and features to suit a wide range of needs.

If you work from the same space all the time, we’d still suggest using a normal monitor since you get much more for your money. If you often find yourself hitting deadlines from the cafe, however, or setting up and taking down your home office every day, a portable version makes a lot more sense.

Whether you’re on a budget, looking for the lightest version, or need extra screen size or a touchscreen, these are the best portable monitors of 2020.

Best Overall: Lenovo ThinkVision M14

If you were going to pick the two most important features in a portable monitor, they’d likely be weight and picture quality. Apparently Lenovo had the same idea, and came up with the ThinkVision M14 as a result.

The 14″ display is a little smaller than most of the competition, but it still has the same 1920×1080 FHD resolution that we typically see. This makes for a slightly sharper image than usual, and in this case, a lot less weight. At just 1.3 pounds, it’s significantly lighter than our other recommendations.

The M14 has an unusual design, with the screen connected to a fold-up base via a fancy hinge mechanism. The display itself is just 0.17″ (4.4m) thick, and can be adjusted to an angle anywhere from -5 to 90 degrees. The base unit holds all of the ports and circuitry.

There’s a small “foot’ on the front of the base that can be flipped down for extra height, and the monitor stays solidly in place in both landscape and portrait orientation. Overall, there’s a lot more viewing flexibility than anything else on this list.

Color reproduction isn’t the strong suit of most portable monitors, but here again the M14 shines, with accurate colors across the range. It’s also nice and bright, and the anti-glare coating means you’ll still be able to see what’s on the screen even under harsh fluorescents or sunlight.

The monitor has two USB-C ports, one on each side. It draws power from the laptop as usual, but also supports 65W power pass-through so you can plug your charger into one side, your laptop into the other, and power both at once. That’s useful if your laptop only has a single USB-C port.

Note that USB-C is your only connection option: there’s no support for USB-A DisplayLink, HDMI, or anything else. That shouldn’t be an issue with recent laptops, but will be with older ones.

The minimal weight, impressive color reproduction, and sturdy, flexible stand combine to make the ThinkVision M14 our top overall portable monitor pick. As long as you have a recent laptop with USB-C, there’s an awful lot to like and very little to complain about.

Pros
  • Very lightweight
  • Good color reproduction and brightness
  • Base acts as a sturdy stand
  • Flexible screen angle
  • Two USB-C ports, with power pass-through
Cons
  • USB-C only. No USB-A or HDMI support for older machines

Runner-Up, Best Overall: Asus Zenscreen Go MB16AP

Asus has been making portable monitors for years, and it shows. The company sells a range of different models, and two have made it onto our list. The Zenscreen Go MB16AP is the better choice for most people, and one of our top portable monitor picks overall.

The monitor is slim and quite lightweight, with an attractive dark grey frame. The 15.6″ display is standard for a portable monitor in 2020, as is the 1920×1080 FHD resolution.

It ships with a case that both protects the monitor in transit, and with a bit of origami, acts as a stand that holds it upright in either portrait or landscape mode. You can adjust the viewing angle via the various grooves on the base of the stand.

Despite not being a touchscreen, it also comes with a stylus that can be stuck into the hole on the bottom right corner of the monitor to hold it in place without the case. It’s unusual but actually works pretty well, especially if you’re cramped for room on your desk.

What really sets this monitor apart from the rest, however, is its built-in 7800mAh battery. While it can draw power from a wall socket or your laptop like other portable monitors if required, it doesn’t have to.

Powering a portable monitor drains a laptop’s battery much more quickly, so the MB16AP is ideal if you’re working for hours in a cafe or anywhere else where outlets are hard to come by. You’ll get up to four hours out of the internal battery before needing to power from something else.

There’s a single USB-C port on the monitor that handles both display and power, and a USB-C to USB-C cable in the box. Asus includes a small adapter that lets you plug it into a USB-A port as well, although you’ll also need to install a DisplayLink driver.

Brightness and contrast are above average for a portable monitor, but colors can be a little dull, however, especially in the red part of the range. It’s an issue common to many portable monitors, so if you need the best color accuracy, consider the Lenovo M14 (above) instead.

All in all, this is a portable monitor that gets pretty much everything right. It’s well-made, with good brightness and viewability, and works with both older and more recent laptops. Attractive, reasonably lightweight, and with extras that set it apart from the pack, it’s a solid choice for a wide range of buyers.

Pros
  • Has its own battery
  • Can use either pen or case to hold monitor in place
  • Stylish
  • Works with wide range of devices
Cons
  • Colors somewhat dull

Best on a Budget: Lepow Z1 Pro

Portable Monitor - Lepow Upgraded 15.6 Inch 1920 x 1080 Full HD USB Type-C Computer Display Ultra-Slim IPS Screen with HDMI Type-C Port Dual Speaker Game Monitor for PC MAC Laptop PS4 Xbox Cellphone

You’ve basically got two choices when it comes to portable monitor manufacturers: one of a handful of major brands (Lenovo, HP, Asus) or any number of Chinese companies you’ve never heard of. Lepow is very much the latter, but it’s actually been in the market for quite a while.

The Z1 Pro is an upgraded version of the popular Z1 model, with basic specifications that are exactly what you’d expect from a budget portable monitor in 2020: 15.6″ display, 1920×1080 resolution, mediocre color reproduction.

What sets the Z1 Pro apart from the dozens of other no-name portable monitor brands, then? It’s the little things. For starters, as well as the ubiquitous USB-C option, there’s also a micro-HDMI port on the monitor and the appropriate cables to use either option.

The case turns into a stand, as usual, but there are two grooves in the base to give at least some choice of viewing angle. The stand only works in landscape mode, but the monitor itself supports portrait mode: you’ll just need to find a different way of keeping it in position.

For a 15.6″ monitor, the Z1 Pro is surprisingly light at 1.7 pounds. Even with that low weight, there are a pair of speakers built into the monitor, along with a headphone jack. The speakers are quite weak, so you’re more likely to use the ones on your laptop, but still, it’s a nice touch.

The biggest problems with this monitor are the color reproduction and brightness. As with many others, reds and purples appear quite washed out, and while you can change various settings to try and make up for it, the alternative is having every other color look unnaturally saturated.

The brightness level also isn’t great. While the specifications suggest the same nominal 300 nits as our top pick, the ThinkVision M14, the Z1 Pro is a lot dimmer in the real world. It’ll be fine indoors in normal lighting, but don’t expect great visibility in direct sunlight.

If neither of those things is a deal-breaker, the Z1 Pro offers plenty of monitor for not a lot of money in a lightweight and easily transportable package. Throw in a three-year warranty, and you have our budget portable monitor choice for 2020.

Pros
  • Good price
  • HDMI support as well as USB-C
  • Lightweight for a 15.6″ model
Cons
  • Poor color reproduction
  • Not as bright as the specifications suggest
  • Stand doesn’t support portrait mode

Best With a Touch Screen: Asus Zenscreen Touch MB16AMT 

Asus Zenscreen MB16AMT 15.6' Full HD Portable Monitor Touch Screen IPS Non-Glare Built-in Battery and Speakers Eye Care USB Type-C Micro HDMI W/Foldable Smart Case

If you’re used to having a touchscreen on your laptop display, there’s no reason you can’t have one on your second monitor as well. As the name suggests, the Asus Zenscreen Touch is the touch-enabled version of the Go model mentioned above, with almost exactly the same specifications.

There’s the same 1920×1080 resolution on a 15.6″ display, the same internal battery so you don’t need to draw power from your laptop, and the same muted color palette that’s common to pretty much every portable monitor except the Thinkvision M14.

The main difference, of course, is the screen. Multitouch-enabled, you’ll get full touch support on Windows and some Android devices, limited support on macOS (since it’s not built into the operating system,) and none on iOS. It’s relatively bright for a portable monitor, which is a nice change.

As with the non-touch model, you get an Asus e-ink pencil in the box, but here you can use it for more than holding the screen upright. Whether you’re using your finger or the stylus, the display is reliable and quick to respond to your input.

Controlling the various settings is done via a single button on the bottom of the monitor that’s actually a five-way joystick. It’s one of the better approaches to menu navigation we’ve seen, but there’s also a Windows app that lets you configure many of the same settings.

The Touch works over either USB-C or the combination of micro-HDMI and USB-A, and all of the cables and adapters you need come in the box. There’s a pair of speakers built-in, which work fine but are probably no better than the ones you have on your laptop already.

Weighing only slightly more than it’s non-touch siblings, if you’re looking for the best portable touchscreen monitor of 2020, you’ve found it in the Asus Zenscreen Touch.

Pros
  • Touchscreen works well
  • Comes with a stylus
  • Both USB-C and HDMI/USB-A options
  • Internal battery
Cons
  • Heavier than non-touch models
  • Colors somewhat dull

Best for Extra Screen Size: Eleduino M173A

Eleduino 17.3 Inch Portable Gaming Monitor,2k Resolution 120Hz,5 Ms Anti-Glare TN Panel High Brightness, Eye-Care,with HDR FreeSync, Type-C, HDMI Built-in Speakers

Large portable monitors seem like a bit of an oxymoron, and manufacturers seem to agree. It’s difficult to find anything bigger than about 15.6″, and even harder to track down something that size that’s worth buying.

The rare exception is the Eleduino M173A, a 17″ model that’s pitched at gamers but is equally useful for anyone else needing more portable screen space than a 14 or 15-inch monitor can provide.

With a 2560 x 1440 resolution, 120Hz refresh rate, and 5ms response time, the M173A is no slouch in the specifications department. It has both USB-C and mini-HDMI connections, and appropriate cables in the box.

The case/stand has multiple grooves to let you select a viewing angle, but only in landscape mode. You’ll be able to switch to portrait mode from your laptop settings, but will need to lean the monitor against a solid object or find some other way of keeping it upright.

Brightness levels are quite good, but color reproduction is less so, with the muted reds and purples we’ve often come to expect. As with many other portable monitors, stereo speakers are built-in, but you’re unlikely to use them in preference to headphones or the ones built into your laptop.

At 3.3 pounds (1.5kg), it’s around twice the weight of the smaller models mentioned above. That’s not bad for something this size, but you’ll definitely know when you’ve got it in your bag. Bigger screens just weigh more: it’s as simple as that.

Pricing for this model is usually quite competitive, with the M173A often costing not much more than some of the better 15.6″ versions. If you need the extra screen size, this Elduino monitor is where it’s at.

Pros
  • Extra screen size
  • High refresh rate and response time
  • Several options for viewing angle
Cons
  • Stand doesn’t work in portrait mode
  • Mediocre color reproduction
  • Relatively heavy

    The best portable display for a Mac is an iPad, used with Sidecar. It is bright, true colors, connects even by WiFi and adds touch + pencil support. Yes, it will cost more than a travel monitor, but if you have one, it is the perfect fit.

      Yeah, we talk about that option here (albeit with Duet and other apps rather than Sidecar). If you already have an iPad and are happy with the smaller screen size, it’s a good choice.
