After a leak and Japanese details earlier this week, Dell on Friday brought its SX2210T display to the US. It represents Dell's first dedicated multi-touch display and supports one- or two-finger input in operating systems that recognize them, particularly Windows 7. Regardless of platform, the 21.5-inch LCD is relatively high quality for a TN-based panel with an 83 percent color gamut and a 50,000:1 contrast ratio.
