Hey guys,

I have a Dell ST2220T monitor plugged into my samsung 5 series i7 3630qm laptop with windows 8 as an extended monitor through hdmi. I want to get the multi touch function but the touch function is not working at all. I have installed "dell_st2220t-touch-monitor_a00-00_driver" and plugged in my upstream usb to the laptop, but when i checked with tablet PC setting through control panel, I see it said only "limited touch support" when i selected st2220t monitor. It did however recognized in device manager there are:
2x "HID-compliant consumer control device"
4x "HID-compliant device"

and in Devices and Printers there are:
HID Keyboard Device
HID-compliant mouse
LGD-MultiTouch
Dell ST2220T
Dell ST2220T (Intel(R) Display Audio)

Please help. Thanks.

PS- I also tried setting the monitor as main monitor and also duplicate and yet still no luck.
