6 monitors worth checking out for 2021BenQ, Asus, HP and more make our first cut of monitor recommendations for 2021 Among PC brands, ASUS and Lenovo – veterans of DisplayLink primacy – offer products, as do at least a half-dozen lesser-known brands such as Lepow, Desklab, and Vankyo. Note that these products will burn through laptop batteries, so it’s best to use them with the laptop plugged in or connect them to a battery pack that supports USB-C Power Delivery. A space-saving twist on the portable monitor is from MobilePixels. Its Duex add-on, available in 12.5-inch and 13.3-inch variations, attaches magnetically to the cover of your laptop and offers a slide-out display that can be tilted forward a bit. The company also offers a kickstand accessory, so you can use the Duex display as a more traditional USB monitor, and the larger Plus version can also be used in portrait orientation. Even though the new generation of Duexes (Duexen?) are lighter than its earlier products, they add significant weight and thickness to the laptop and the magnets will prevent convertibles from 360-degree hinge rotation. In addition, there’s no storage or attachment option for the USB cable needed to drive the monitor.  However, if your work almost constantly demands two displays, it could be a good option. MobilePixels has also been readying a two-screen variant of the slide-out display called Trio (for the three total screens that include the laptop’s internal display). This portable dual monitor is the most affordable way to add a second screen to your laptop Working from home is becoming the new normal. Investing in a portable monitor from Mobile Pixels is a strong move for your career: now and in the future.
