PC Connection Express offers the 4-lb. Mobile Monitor Field Monitor Pro 15.4″ 720p USB 2.0 LED-Backlit Widescreen LCD Monitor, model no. FMP154A, for $289. With free shipping, that’s $9 under the lowest total price we could find for an 11″ portable monitor (this one is 15.4″), although we saw it for $10 less in June, since expired. This portable folding monitor, which is designed to accompany a laptop, features a 1280×800 (720p) native resolution, built-in numeric keypad, three USB ports, AC adapter, and more.
