Portable monitors are worth it if you work on a laptop and often wish you had a second screen. They’re thin, light and run off a single cable, so you can have two displays at a coffee shop, a hotel or your kitchen table. If you rarely need more screen space, you can skip one.
So who actually gets the most out of them? Let’s go through it.
What a portable monitor is
A portable monitor is a slim display, usually 13 to 17 inches, built to travel. Most connect to a laptop with one USB-C cable that carries both video and power. Many also come with a stand or fold-out cover so you can set them up anywhere.
Who benefits the most
Think about how you work. A second screen is a big deal if you juggle windows all day.
- Remote workers and travelers: you can keep email on one screen and a document on the other, even in a hotel.
- Students: notes on one side, lecture or reading on the other.
- Developers and writers: code or draft on one screen, reference material on the other.
- Anyone with a small laptop: a 13-inch screen gets cramped fast.
- Presenters: a second display is handy for notes while the main screen is shared.
Our guide to the best portable monitors for laptop work focuses on this kind of everyday use.
What you give up
It’s not all upside. Here’s the catch: a second screen adds weight to your bag and another cable to your desk. Most are fairly light, but you’ll still notice the weight on a long day.
Battery is another factor. When the monitor draws power from your laptop, the laptop’s battery drains faster. If you’re not near an outlet, that matters.
Image quality also varies. Portable screens are usually fine for documents and web pages, but color accuracy and brightness can fall short of a good desktop monitor, particularly in bright rooms.
Are they better than just buying a bigger monitor?
If you work at one desk all the time, a full-size monitor is usually a better deal. You get a larger screen and better stand for the same money or less. A portable one only wins when you move around, or when you don’t have space for a big display.
What to check before you buy
- Port type: make sure your laptop’s USB-C port supports video output.
- Size and weight: bigger is nicer, lighter is easier to carry.
- Resolution: sharper text is easier on your eyes during long sessions.
- Brightness: higher helps near windows.
- Stand or cover: a good stand makes a real difference.

Real-life ways people use them
It helps to picture how a portable monitor fits into an ordinary day. Say you’re a consultant on a train, writing a report. The report sits on your laptop, and your research stays open on the second screen. No more flipping back and forth between windows, and that alone can save a lot of time.
Or imagine you work at the kitchen table. You set the monitor up for a long meeting, then fold it away at dinner. You haven’t given up any permanent desk space, which is something a full-size screen can’t do.
Some people also use one as a small display for video calls, a chat window or a to-do list, so their main screen stays clear for the real work.
How much does a second screen help your work?
It’s a fair question. Many people feel more productive with two screens, mainly because they spend less time shuffling windows around. But how much it helps depends on your tasks. Spreadsheets, writing with research, coding and editing all benefit. Reading a single document or browsing the web may not.
A good test is to look at how often you switch windows today. If you do it constantly, a second screen will likely feel like a relief. If you rarely do, you may not notice the difference.
Tips if you decide to buy
- Choose a size that fits your bag, since a screen you leave at home isn’t helping.
- Look at the viewing angles, so the picture stays clear even if you’re not directly in front of it.
- Think about a protective cover or sleeve for travel.
- Try it in the room you’ll use it in, because glare changes everything.
Frequently asked questions
Do portable monitors need their own power?
Most run off the laptop’s USB-C port. Some also have a second port so you can plug in a charger and avoid draining the laptop.
Can a portable monitor work with a phone or game console?
Often yes. Many work with phones that support video over USB-C and with consoles through HDMI, though you’ll need a power source for some setups.
Are touchscreen portable monitors worth it?
They can be handy for presentations and tablet-style use. If you mostly type and read, you probably won’t miss it.
