Configuring Multiple Screens
If you are using a multi-monitor graphics card to spread the
Windows NT desktop across more than one monitor, you can use the
Multi-screen Configuration option to map the touchscreen to the
portion of the desktop displayed on the touchscreen monitor.
MicroTouch currently supports the use of up to 4 monitors. However,
only one monitor can have a touchscreen. Use the Multi-screen
Configuration drop-down list to specify which portion of the desktop
(the portion displayed on the touchscreen monitor) is the touchscreen.
For example, if you are displaying the desktop horizontally across two
monitors, and the touchscreen is installed on the right monitor, choose
Right half to map the right half of the desktop to the touchscreen.
Note:
To correctly calibrate the touchscreen, you must have the
appropriate Multi-screen Configuration setting selected.
In order for the Multi-screen Configuration settings to work properly,
your monitors and video card must be configured correctly for the
multiple monitor arrangement. For more information about how to set
up your system correctly, refer to your system documentation and
documentation for the video card.
The Multi-screen Configuration list includes the settings for all
multiple monitor configurations. Choose a Multi-screen Configuration
setting that works with the number of monitors you are using to
display the desktop. Refer to Table 7 for a list of the Multi-screen
Configuration settings that are appropriate for each multiple monitor
configuration.
Note:
In all multiple monitor configurations the monitors must be
arranged horizontally, except when using two monitors. You can
arrange two monitors horizontally or vertically.
