AOC e1659Fwu 16″ USB-Powered Portable LED-Backlit Monitor for $129.99 shipped. Here is a screenshot for your reference. It is a single-cable solution as the monitor is USB-powered and the display signal goes through the same USB cable. This makes it a great way to have a dual-monitor setup on the go. A carrying case is also included. This could also be used as a second monitor for some tablets running Windows.
