They say that as soon as you go with a dual monitor configuration at your workstation that you simply cannot go back to using a single screen again. That may or may not be true, but the resource draw of running an external monitor can be a bit much for some people. That’s why the family of USB monitors from DoubleSight is so darn convenient.
Rather than requiring the graphics card on your laptop or desktop to power a second screen, these monitors latch on via a single USB connection. That single USB cable provides both the power for the external monitor and the data feed, making for a very simple and clean setup process.
DoubleSight is going even further with this idea by including an integrated webcam on one of their newest models. The range-topping $160 version gives you a 9-inch screen (1024×600) and a webcam. It’s really quite impressive that this is all done through a single USB cable.
If you want to save some money, the nine-inch model without a webcam is $140 and it features the same 1024 x 600 pixel resolution. For people who want to save some more money and get something more compact, there is also a seven-inch model for $120, though you get bumped down to a 800 x 480 pixel resolution. All versions work in landscape or portrait.
