Spurred on by the release of Windows 7, the number of screens on the market offering the benefits of multi-touch functionality has jumped significantly in recent times. Acer, HP and Toshiba have released multi-touch notebooks and we've also seen multi-touch creep into the desktop and all-in-one PC arenas. Dell has had multi-touch PCs in its sights for a while and recently released the rugged Latitude multi-touch tablet. Now there's the Dell SX2210T – a 21.5 inch, 16:9 widescreen multi-touch monitor with full HD and integrated webcam.

The Windows 7 compatible optical touch screen caters for single-touch (Flick, Scroll, Tap, Drag) and multi-touch (Grab, Rotate, Double –Tap, Zoom In/ Out) interaction and can be used with a stylus or pointer as well as fingers.

The 2MP integrated webcam has two microphones and other key specs include a 1920 x 1080 resolution (at 60Hz), typical response time of 2ms, optimal brightness of 220cd/m2, 50,000:1 (max.) dynamic contrast ratio, 160 degree viewing angle. Connectivity is via Analog (VGA), DVI-D (HDCP), HDMI plus audio in/out and 4 x USB 2.0 ports.

The Dell multi-touch monitor is priced from US$469.
