Sideline has now began shipping its CINQ secondary monitor for notebooks. The 10.1-inch, 1280×720 display is under an inch thick while weighing under 1lb. Like other, normally smaller screens, it connects solely over USB and is designed to be portable.
An SD card reader is built-in, and the design auto-rotates to landscape or portrait, as needed. A hard case is included, along with an attachment rail to clamp it onto notebook lids. It adjusts for height as well.
The CINQ is both Mac and Windows compatible and is available in black, white or orange for $249.
