A USB mobile display has been good at showing a presentation to a small group or expanding desktop estate when on the go. The Lenovo ThinkVision LT1423p Touch, however, redefines this category with its own touchscreen. Notebook owners recently upgraded to Windows 8 may appreciate this as the portable monitor is designed from ground up to be a companion for the new touch-optimized OS.

For those who are familiar with Lenovo’s older sibling ThinkVision LT1421, the new monitor is a big step up in specs from features to screen quality. Where the LT1421 is simply a non-reflective TN+ screen maxing out at 1366 x 768, the LT1423p has a 13.3″ AH-IPS panel with a resolution of 1600 x 900. It easily excels in terms of viewing angle and color accuracy where older USB monitors pale in comparison.

The touchscreen itself is protected by Corning’s Gorilla Glass, and is capable of registering up to 10 different touch-points. It also comes with a Wacom stylus that detects 256 levels of pressure sensitivity. The pen can be used for collaborative work in real-time with another user on a touchscreen laptop (e.g. X1 Carbon Touch). With the LT1423p, you can stand the screen up and prop it up like a tent, or you could hold it like you would with an iPad.

Video performance and response time shouldn’t be a problem as everything from power to data is handled via USB 3.0. There’s actually a Wi-Fi, USB 3.0 hybrid model ($449) but oddly the battery pack is optional, and there’s a price premium for wireless connectivity. So, for $349, the wired USB 3.0 version seems like a better deal.
