We've never had the chance to play with a USB monitor before, so when Lenovo offered to send over the ThinkVision LT1421 we told them that we'd most certainly take a look at it for them. The ThinkVision LT1421 is a 14-inch wide flat panel monitor that supports up to 1366x768 resolutions and uses a standard USB 2.0 port for the video stream and as a power source. The point of this unique monitor is to offer those that travel a way have a secondary monitor for ad-hoc meetings, without the need of projectors. This would obviously appeal to those that use a laptop for business meetings, sales presentations, academia and a wide variety of other applications. Priced at under $200 ($190.67 shipped to be exact) it makes owning a second screen for on-the-go user affordable.
