Dell Touch Monitor display no working in multi monitor setup windows 7

I had previously problem with this Monitor for its display quality but was solved, now I face problem that I can't use its touch because when I touch anything on monitor, it register on wrong display. I have multi-monitor setup and I am using two monitors. So if I touch Dell touch Monitor, it shows that touch working on another display. Please provide me solution so that I can use it effectively and utilize it properly.

If you are using multiple monitors and one is touch then you need to windows that which one is touch Monitor, for this there is a setting in :
Control Panel --> Tablet PC Settings --> Setup

Run that and read instructions given on it.

I hope that will help.
