Dell today revamped its ST and IN series displays with five new models previously unavailable in the US and the hint of its first touchscreen IPS display. The 22-inch ST2220, 23-inch ST2320 and 24-inch ST2420 all produce a 1080p picture and have LED backlighting that pumps up their dynamic contrast ratios to as much as 8,000,000:1. All have a relatively sleek, rounded design for Dell with touch-sensitive controls on the bezel.
