Productivity or Gaming? Most portable monitors come with a standard 60Hz refresh rate, which is perfectly fine for productivity tasks and suits most consumers.So, if you prefer to connect to your laptop via HDMI, you could do so with just a single cable with battery-equipped monitors. However, some models, like the Asus ROG ROG XG16AHPE and XG17AHPE, have a built-in lithium-ion battery that allows you to game without being plugged into a wall. Battery or no battery? Most modern portable monitors draw power over USB-C, either via a dedicated wall charger or by drawing power directly from your laptop.These are rarely (if ever) better than a good built-in kickstand and can ruin an otherwise good display experience. On the other hand, some monitors have separate, magnetic origami-style covers that double as a kickstand. The best portable monitors have a built-in kickstand that allows you to easily adjust the display for the best possible viewing angles. A kickstand can be a make-or-break proposition for some portable monitors.

Pay close attention to monitor kickstands.A select few provide DisplayLink connectivity, which allows them to plug into any USB 3.0 capable port, even an old-fashioned type-A connector.

Some monitors connect over standard HDMI, which lets them work with almost anything, while others use USB-C’s alternate mode.

Make sure it connects to your device(s).
