Dell SX2210T

The Dell SX2210T is a 21.5" high definition LCD monitor and a touch-screen version of the Dell SX2210. VGA, DVI and HDMI ports are included as well as audio in/out and four USB ports. The fourth USB upstream port hooks up the hub as well as the multitouch touchscreen layer. Resolution is 1920p x 1080p and the contrast ratio is 1000:1, while the touch-panel uses optical touch and has a 2.5mm thick chemically toughened glass layer. There is also an embedded 2 megapixel webcam in the upper bezel with microphone. When the extra USB connection for the touch signal is connected, one of the main features of the SX2210T is the possibility of both panning and zooming when used with Windows 7. This makes it a unique tool for presentations, using your fingers to open and drag pictures or even change 3D perspective while panning and zooming.
