Until now, multi-touch displays have typically been limited to the more affordable TN-based panels which sacrifice image quality to keep costs down. Dell is looking to change all of that with its new multi-touch IPS beast, the 21.5-inch ST2220T.
The ST2220T displays content at a resolution of 1920 x 1080, or what’s commonly referred to as “full HD”. One of the more defining features of the new display is its super-adjustable stand, which lets users fold the monitor flat onto the working surface. Horizontally-oriented displays are far more finger-friendly than their vertically-oriented counterparts.

The touch functionality is based on the same optical multi-touch found in most large form factor, standalone displays and all-in-ones currently on the market. While that means that any object, finger or otherwise, can use the display, it also means that it’s limited to just two fingers.
Unusually, Dell lists some of the touch specifications for the display; the resolution of the touch overlay means a minimum stylus diameter of 7 mm, or just over a quarter of an inch, and a touch response time of 15 ms.
Dell currently has the ST2220T available for twenty bucks off, at $309.99.
