I know that there are several generations of touch-screen technology out there. There is the ancient resistive touch, pre win7 era capacitive, pre win7 era multitouch capacitive, and win7 compliant multitouch capacitive. However Win8 requires yet another new generation of hardware. I have been unable to find any Windows 8 compatible multi-touch capacitive monitors that will work with a regular desktop PC. The use (primary application) would be for development and test of multi-touch windows applications.
I'm not asking if any all-in-one PCs that support windows 8 multi-touch exist, for those are a different class of device, nor devices like Surface. I want to know if there is such a thing as a monitor that is standalone that will run with a regular developer mini-tower PC, that supports multi-touch in windows 8.
