What Is a Portable Monitor?
A portable monitor is a thin, lightweight external display, usually 14 to 16 inches, designed to travel with a laptop and add a second screen anywhere. Most portable monitors connect and draw power through a single USB-C cable, so you can set one up on a desk, table, or tray in seconds.
Portable monitors are sometimes called travel monitors or laptop companion monitors. This page explains how they work, what they’re used for, how they compare with desktop monitors and tablets, and what to look for when choosing one. For an overview of how monitors work, see what a computer monitor is.

How Portable Monitors Work
A portable monitor works like any external monitor, but it’s designed to run with minimal cables and power. Most models receive both the video signal and their power from your laptop through a single USB-C cable, so there’s no separate power adapter to carry.
Single-cable USB-C connection
When you connect a portable monitor to a laptop USB-C port that supports video output, such as DisplayPort Alternate Mode or Thunderbolt™, the same cable carries the display signal and powers the monitor. If your laptop’s USB-C port doesn’t support video, the monitor won’t display an image through that port. Learn how USB-C carries video and power.
Other connection options
Some portable monitors also include a mini-HDMI or HDMI input for devices without video-capable USB-C ports. HDMI doesn’t carry power to the monitor, so these connections typically need a separate USB-C power source, such as a wall charger or power bank. Some models also include pass-through charging, which lets you plug a charger into the monitor and power both the monitor and the laptop.
Built-in stands and covers
To stay slim, most portable monitors don’t use a traditional stand. Instead, they include a built-in kickstand or a folding protective cover that props the screen up. Some kickstands rotate or adjust to support portrait orientation.
What Are Portable Monitors Used For?
Portable monitors are used to add a second screen wherever you work with a laptop, from hotel rooms and client offices to coffee shops and kitchen tables. They bring some of the multitasking benefits of a desk setup to places where a full-size monitor isn’t practical.
Business travel: Keep email or a reference document open beside your main work in a hotel or on-site.
Hybrid work: Carry the same two-screen setup between home and a shared or hot-desk office. Learn more about hybrid work technology.
Students: Spread notes, research, and assignments across two screens in a library or dorm.
Presentations and demos: Turn the screen toward a client across the table while you keep your laptop screen for notes.
Creative and technical work: Place tools, timelines, or code on one screen and your main project on the other.
Small spaces: Add a second screen at home without dedicating desk space to a full-size monitor.
Portable Monitor vs. Desktop Monitor vs. Tablet as a Second Screen
A portable monitor trades size, brightness, and adjustability for portability. A desktop monitor is better for a permanent desk setup, while a tablet can work as a second screen but depends on software support and its own battery.
Feature | Portable monitor | Desktop monitor | Tablet as a second screen |
|---|---|---|---|
Typical size | 14 to 16 inches | 22 to 34 inches and larger | 10 to 13 inches |
Portability | Slim and light enough for a laptop bag | Stays at one desk | Very portable |
Power | Usually powered by the laptop over USB-C | Wall power | Its own battery |
Connection | USB-C, sometimes mini-HDMI | HDMI, DisplayPort, USB-C | Wired or wireless, through supported apps or operating system features |
Stand and adjustment | Kickstand or folding cover with limited adjustment | Often height, tilt, swivel, and pivot | Case or separate stand |
Brightness and refresh rate | Often lower than desktop monitors | Widest range of options | Varies by tablet |
Best for | Travel, hybrid work, temporary setups | Permanent home or office workspaces | Occasional extra screen space with a device you already own |
For a permanent workspace, a desktop monitor or a multi-monitor setup offers more screen space and better ergonomics. For tablets as standalone devices, see the tablets glossary.
What to Look for in a Portable Monitor
The most important things to check in a portable monitor are how it connects to your laptop, how much it weighs, and whether its size and resolution match your laptop screen. Brightness, the stand design, and extra ports also affect how useful it is on the go.
Feature | What to look for | Why it matters |
|---|---|---|
Connection | USB-C with DisplayPort Alternate Mode; HDMI if you need to connect other devices | Determines whether one cable can carry video and power |
Power | Laptop-powered over USB-C, with optional pass-through charging | Reduces cables and lets you charge the laptop through the monitor |
Size | 14 to 16 inches | Matching your laptop screen size makes the two screens feel balanced |
Weight and thickness | Light and slim enough for your laptop bag | Affects how often you’ll actually carry it |
Resolution and aspect ratio | Full HD or higher; 16:10 for extra vertical space | Sharper text and more room for documents |
Brightness | Enough to read comfortably in your usual work locations | Portable monitors are often dimmer than desktop monitors |
Stand | Sturdy kickstand or cover, ideally with portrait support | Keeps the screen stable on different surfaces |
Screen finish | Anti-glare coating | Reduces reflections in hotels, offices, and outdoors |
Touch | Touch screen, if you want to tap and scroll | Useful for presentations and pen or touch-friendly apps |
Example: HP Series 5 Pro 14-inch Portable Monitor
The HP Series 5 Pro 14-inch Portable Monitor (514pn) shows how these features come together. It has a 14-inch 2560 x 1600 resolution IPS display in a 16:10 aspect ratio, weighs about 1.4 lb with its stand, and connects through two USB-C ports that support DisplayPort Alternate Mode and up to 65W of USB Power Delivery for pass-through charging.

How to Connect a Portable Monitor to a Laptop
Connecting a portable monitor to a laptop usually takes one cable and a few seconds. These steps apply to Windows 11 laptops; menu names may differ slightly in other versions.
Confirm your laptop has a USB-C or Thunderbolt port that supports video output. Look for a DisplayPort or Thunderbolt icon next to the port, or check the laptop’s specifications.
Connect the portable monitor to that port with the USB-C cable that came with it.
Set up the kickstand or cover, and position the monitor beside your laptop.
Press Windows key + P and choose Extend to use the portable monitor as additional screen space.
Open Settings > System > Display to arrange the screens to match their physical positions and adjust resolution or scaling.
If your laptop only has HDMI, connect the monitor’s HDMI input and plug the monitor into a USB-C power source. Learn how to set up and arrange multiple monitors.
Portable monitors and laptop battery life
A portable monitor powered by your laptop draws from the laptop’s battery when you’re unplugged, so the battery drains faster than usual. Lowering the monitor’s brightness helps. When an outlet is available, connect your laptop charger to the monitor’s pass-through port, if it has one, to power both devices. Learn more about laptop batteries.
Positioning a Portable Monitor for Comfort
Portable monitors sit low on the table, like a laptop screen, so a little planning helps keep your neck and eyes comfortable during longer sessions.
Place it beside your laptop: Set the portable monitor next to your laptop at a similar height and angle, and tilt both screens slightly toward you.
Use portrait mode for documents: If the stand supports it, rotate the monitor vertically for long documents, code, or chat windows.
Raise both screens for long sessions: A laptop stand and a raised surface for the portable monitor bring the screens closer to eye level. Pair them with an external keyboard and mouse.
Mind the glare: Angle the screen away from windows and overhead lights, and adjust brightness to match the room.

Frequently Asked Questions About Portable Monitors
Does a portable monitor need its own power source?
Most portable monitors don’t need their own power source when connected to a laptop USB-C port that supports video output, because the same cable delivers power. A portable monitor connected through HDMI, or to a laptop port that can’t supply enough power, needs a separate USB-C charger or power bank.
Which devices work with a portable monitor?
Portable monitors work with most laptops that have a USB-C port with video output, including many Windows laptops, Chromebooks, and Macs. Some phones and tablets with USB-C video output can also connect directly. Game consoles and other devices without video-capable USB-C can connect through the monitor’s HDMI input, if it has one, with separate power.
Can you use two portable monitors with one laptop?
A laptop can run two portable monitors if it has two USB-C or Thunderbolt ports that support video output, or one port that supports multiple displays. Running two monitors from laptop power drains the battery faster, so connecting a charger is helpful for longer sessions.
Is a portable monitor worth it?
A portable monitor is worth it for people who regularly work away from a desk and want a second screen for multitasking, such as frequent travelers, hybrid workers, and students. For a single permanent workspace, a full-size desktop monitor usually offers a larger screen, higher brightness, and better ergonomics.
