Best Portable Monitors 2025: Double Your Screen Space Anywhere with These Ultra-Slim Displays That Fit in Your Bag

Working on a single laptop screen feels cramped once you've experienced the freedom of dual displays. But what if you could take that productivity boost anywhere? That's where portable monitors shine—literally.

We've tested and researched the most popular portable monitors of 2025 to help you find the perfect second screen for your mobile setup. Whether you're a digital nomad, a traveling professional, or just someone who wants more screen space at the coffee shop, there's a portable monitor here that'll transform how you work.

Why You Need a Portable Monitor

If you've ever found yourself frantically alt-tabbing between windows or squinting at a tiny laptop screen while traveling, you already know the problem. A portable monitor gives you:

• Instant productivity boost: Research shows dual monitors can increase productivity by 20-30%
• True portability: Most models weigh less than 2 pounds and are thinner than your laptop
• Simple setup: Modern USB-C connectivity means one cable for both power and video
• Versatility: Perfect for work, gaming, presentations, or extending your tablet or phone display

What to Look For in a Portable Monitor

Screen Size

The sweet spot is 13-15.6 inches—large enough for real work but still portable. Bigger 17-inch models offer more space but sacrifice portability.

Resolution

Full HD (1920x1080) is the minimum for crisp text. If you work with photos, videos, or design, consider 4K (3840x2160) for stunning clarity.

Connectivity

USB-C is king—it handles video, power, and data through one cable. Make sure your laptop supports USB-C video output. HDMI is a useful backup option.

Power Options

The best portable monitors draw power through USB-C, eliminating the need for a separate power adapter. Some also include battery packs for true wireless operation.

Build Quality

Look for a durable aluminum frame, a protective cover that doubles as a stand, and anti-glare coating for outdoor use.

How to Set Up Your Portable Monitor

Getting started is surprisingly simple:

1. Connect the cable: Plug the USB-C cable into your laptop and monitor. If your laptop doesn't support USB-C video, use an HDMI cable and USB-A for power.

2. Adjust display settings: Your computer should automatically detect the monitor. On Windows, press Win+P to choose how to use your displays (extend or duplicate). On Mac, go to System Preferences > Displays.

3. Position your screen: Use the included stand or case to prop up the monitor at a comfortable viewing angle. Most stands offer multiple positions.

4. Fine-tune brightness and color: Adjust the monitor's settings using the on-screen controls or buttons to match your laptop's display.

Pro Tips for Portable Monitor Users

Protect your investment: Always use the protective cover when traveling. These thin displays are surprisingly durable, but better safe than sorry.

Check your laptop's USB-C specs: Not all USB-C ports support video output. Look for the DisplayPort or Thunderbolt icon next to the port.

Consider a USB-C hub: If you need more ports, get a hub that supports video passthrough so you can use your portable monitor and other peripherals simultaneously.

Adjust for lighting: Many portable monitors have lower brightness than laptop screens. Position yours away from direct sunlight or invest in a model with 300+ nits of brightness.

Pack smart: Place your portable monitor in your laptop compartment with the protective cover on. Most are thin enough to fit alongside your laptop.

For most people, the ASUS ZenScreen MB16ACV offers the best combination of features, portability, and value.
