Asus LS221H is a 22-inch widescreen LCD monitor which is claimed by the company as the slimmest (248mm thick) 22-inch display in the world. It comes with a WSXGA+ resolution (1680×1050) and sports a brightness of 300cd/m2, a contrast ratio of 4000:1 featuring ASCR (ASUS Smart Contrast Ratio), a 170/160 degree viewing angle, a response time of 2ms, and a D-Sub and HDMI inputs. The monitor also incorporates ASUS proprietary Splendid Video Intelligence technology and comes with 5 video preset modes as well as 3 skin-tone selections.

With a thinness of just 248 millimeters, the LS221H is so slim that it seems like more of an object de art than a display unit. Clean lines, diamond-cut corners and edges of glass combine seamlessly on the piano-painted glossy black chassis; while the lower half panel of the LS221H is dressed in genuine leather to present an exquisite outlook that exudes luxury and warmth in digital living.
