If one screen is good, two are better. The best portable monitors provide extra space for spreadsheets, presentations, videos, and gaming, all while being thin and light enough to take anywhere. Below is a roundup of five top models you can buy right now, starting under $100.

These monitors are great for productivity and can also connect to game consoles like Xbox and Nintendo Switch, as well as most phones (often requiring a USB-C cable). After the reviews, find guidance on how to choose a monitor and answers to common questions.

1. Best Budget: MNN Portable Monitor 15.6-Inch
Priced around $100, this monitor offers solid value with thorough documentation and support for portrait mode. However, colors can appear muted, and it's a bit heavy.

2. Best Touchscreen: ViewSonic TD1655
This $300 model features a bright, colorful touchscreen and includes a stylus. Its built-in stand supports both landscape and portrait viewing, though the glossy screen shows glare.

3. Best OLED: ViewSonic VX1655-4K-OLED
Ideal for 4K laptop users, this $500 monitor delivers exceptionally vivid colors via OLED technology. It includes a built-in stand but carries a risk of image burn-in.

4. Best Attachable: SideTrak Swivel Pro
This $550 monitor physically attaches to your laptop for easy transport. It offers vibrant colors and a versatile hinge but requires a semipermanent mounting plate.

5. Best Triple-Screen: Xebec Tri-Screen 2
For $325, this innovative accessory adds two 10-inch screens to your laptop, effectively tripling your workspace. The screens are sharp but can be dim compared to a primary display.

When choosing a portable monitor, consider size, resolution, touch capability, ports, speakers, stand versatility, and warranty length. Most connect via USB-C and can be powered by your laptop, though this may affect battery life. They are also compatible with game consoles and smartphones, making them versatile for both work and entertainment on the go.
