This article details some of the possible issues with multiple monitor setup in the Windows NT v3.1c driver

The below describes possible multiple monitor setup problems in the Windows NT v3.1c driver.

NOTE: Windows NT is no longer supported by Microsoft or Elo Touch Solutions.

Multiple Monitor Setup Problems

The NT3.10c driver has a visual Setup for any configuration of one to four monitors. Single, horizontal, vertical and stacked orientations are available, and any monitors in a multiple monitor setup may be specified as a non-touchmonitor (select None instead of assigning a COM port). If you need multiple monitor capability and do not have this simple visual Setup interface, you need only upgrade to the 3.10c version of the driver.
