Touch Screen in multi monitor setup
Posted on 2011-02-11
I have been running two LCD screens for over a year but a change in the computer program I use (for work) required the addition of a touch screen monitor. I have installed the drivers and it works great. But under Windows 7 (pro 32 bit) I seem to have to set the touch screen monitor as the main display, otherwise every time I touch the screen it tries to register a touch on the primary display ( a non-touch LCD). Is there any way around this?
System info:
Dell XPS 8300
ATI 5770 video card
Primary monitor - Dell 2310H connected via DVI
Second monitor - Dell 2310H connected via VGA (through DP/VGA adapter)
Third monitor - Acer T230H Touch Screen connected via HDMI and USB
I have checked with Acer and they don't have any specific software for the T230H. Do I need to download/purchase some 3rd party software inorder to run this monitor as my 3rd display and still utilize the touch screen capablities?

Maybe changing the Acer to the DVI connector might work, since the puter is looking down the DVI cable to find the main touch-screen monitor- see if that works without the Primary Dell connected at all. If it works, use a different method of connecting the (original) Primary monitor if you can.
The other way would be to start your vga config utility either NVIDIA or ATI console and identify your touch screen as the main monitor using this console. That's normally how you'd configure which monitor is which in most cases.
Sorry, maybe I should be clearer. I do not want the Acer to be the main display. I want the Dell monitor, connected via DVI which is currently the main display to remain the main display. What I want is to be able to touch the screen on the Acer, with it set as the third display, and have Windows recognise that I am activating the program on the Acer screen and not the primary monitor. Does that make sence?
Yeah I totally understand. Problem is I suspect your touch screen driver/app isn't configured for more than one screen being present. If it were there would be an option to configure it as a non-primary screen in the setup process. A possible solution then is to reconfigure your screens, but since you don't want to do that I suggest contacting the touchscreen manufacturer and requesting their assisstance - they will know if your desired config is achieveable given the capabilities of their software.
It might be worth trying uninstalling the drivers via right clicking My Computer, select manage, select Device Manager, locating your touch screen and uninstalling the drivers, then backing out and re-starting the machine. It just might then figure out which screen to apply the drivers to.
Let me know how you get on!
