My DELL ST2220T worked out of the box with Windows 8 Consumer Preview Evalution copy Build 8250.... Works great. I didn't install drivers or anything, they must have auto-installed. I have 2 of them hooked up and both monitors show up under Devices and Printers. Only problem I'm having is when I touch the second screen (the screen on my right), the touch input shows up at the corresponding X,Y location on the first screen (screen on my left). Touch input on the left screen works properly. Any suggestions?
