Asus ZenScreen MB249C: The Best Versatile Portable Monitor
The Asus ZenScreen MB16ACV is the best portable monitor for adding a second screen to your laptop while on the go. It has a 15.6-inch display with a 1080p resolution, good color accuracy, and a bright screen that's easy to read in different lighting conditions. The integrated stand allows for both landscape and portrait orientations, and it connects to your laptop via a USB-C cable. It also has additional software that lets you use a full-size USB cable to transmit video to the portable monitor, making it compatible with older laptops or as a smaller secondary monitor for desktops.
