I installed the driver as Chris suggested. There are 3 drivers in the zip file, analog, digital and HDMI. I installed

both the analog and digital on 2 XP machines. I hooked up the vga and USB cables. The touch screen function did not work.

Do I need to do anything else to active the touch screen function.

Are you running the ST2220t in a dual monitor setup? If yes, the ST2220t must be the primary.

I do aware of the dual monitor issue. I installed the driver on a XP laptop and a XP desktop (only one monitor and one driver).

I also installed the vista driver on a vista machine and it works perfectly and that eliminate hardware problems.

Is any other thing I can try?

Hello,

I have a Dell PC with windows XP, is there a driver existing to get the Dell ST2220T monitor touch-screen to work?

If not, can you provide a solution to upgrade from XP to Win7 ?  ..or a software patch?

Thanks,

I'd also like to know if they plan on releasing a patch for XP. 

Hi, I am also facing the same problem i-e want to use ST2220T with XP machine, but don't have touch  screen driver. Is there any solution to solve this problem.

Hello friends okay?

I have a serious problem. I bought 7 ST2220T DELL monitors to use with a computer with 8 video outputs, these videos are the screen extended Microsoft Windows 7. But when I click on any of the monitors "click" happens on the first monitor and not on the current monitor which I did touch.

Please help me.

Thank you.

1. The Touch Screen functionality and Touch Screen Tools are designed to only work on the Primary monitor.

2. If you want to enable the touch screen functionality on the secondary monitor:
Set the secondary monitor as an extended display
Go to Start -Control Panel -Tablet PC Settings
Click Setup and follow the instructions on the screen

Do update here to tell if you got the 7 ST220T DELL monitors to work with Windows7.
