Cannot calibrate ACER T231H Touchscreen

I just recently bought the ACER T231H Multitouch Screen, but I am not able to calibrate it....Cuz, when I enter the Calibrating part, the only screen that is able to calibrate is my 32 " LG LCD Screen.....Sad( I already downloaded the lates Driver from 2010...Can anyone tell me what is wrong??

Makes sense to me.

Since you only have one screen with a touch system, it makes sense that calibration would only apply to one screen.

It's a shame no one explains such things today.

Still can't calibrate...

Hi, Bob! Yeah, I have only one screen with touch system...The thing is that I didn't mark this screen to be my Primary, as I ave read somewhere that Windows 7 requires that this screen must be set to Primary, in order to function....But, when I hit the Calibrating button, I cannot tap in the Corner, where the markers are....So, problem is still NOT solved....Sad(

So it's a bug.

I can only guess you are tapping on the screen that has the touch capability. And if you find a bug in multiple screen support you are back to Acer and Microsoft to ask if they can fix this.

Workarounds could be to swap the primary screens.
