MultiTaction Display

MultiTaction displays require some special steps for starting, calibration, finger tracking parameters and connecting it to your Mac. More detailed information is available in the manual provided with your display. For your convenience, much of the important information is provided in this section.

Note: The MultiTaction software can be subject to changes by the manufacturer without prior notice. The procedures mentioned below may change at any time. However, the description given will most likely stay valid in its outline.

Starting the Multitouch Display

Use the power switch on the back of the display to turn the device on. Once turned on, the display will boot and show the on-screen display (OSD). After about three seconds, the displayed content will switch to the content of the computer connected to it.

To adjust the configuration of the display, you can connect a USB mouse to a USB port of the display. You may also use a keyboard, although all operations can be done with a mouse. As soon as the display detects a mouse or a keyboard, it switches back to its OSD.


It may be required to perform a display calibration when first taking the display into operation, and if the tracking accuracy has decreased significantly at a later point of time. For this, you need to use the white calibration sheet that is provided with the corresponding device, for instance the T5.5.

To perform calibration, connect a keyboard to the display. The display will switch to its on-screen display. Activate the Calibration tab. Then press the Start auto calibration button and put the white calibration sheet on the display. The calibration procedure may take up to seven minutes. When it is completed, press the "Save" button to save the current calibration settings.

Adjusting Finger Tracking Parameters

To adjust the finger tracking parameters, activate the Calibration tab in the OSD, and click on the Fingers entry. The Defaults button sets the finger tracking parameters to factory defaults. This affects only the finger tracking parameters, it does not affect the overall display geometry.

If the tracking sensitivity needs to be adjusted, click on the Advanced button to get access to all tracking parameters. Only the Required Brightness parameter should be adjusted here. Touch events are shown as light points and streaks. Required Brightness determines how bright these points and streaks must be to trigger touch events.

A lower threshold makes tracking more sensitive, a higher one less sensitive. Typical values are between 0.03, and 0.09. After tuning the Required Brightness parameter, press the Save button. You can always load previous settings by choosing a saved setting from the Archive section.

Connecting the Display

The display is connected to the Touch Player Mac in two ways. Content is displayed through a connection via video cable. The transmission of touches is done via TCP/IP. You may connect the display directly to an Ethernet interface of the Touch Player Mac, or you can connect it to a LAN switch in your network.

When establishing a direct network connection to the Mac, we recommend not changing the default settings on your MultiTaction display. Its default IP address of is at the time being. The corresponding network interface settings on your Mac must be set accordingly. We recommend the following settings.

Configure IPv4 Manually
IP Adress
Subnet Mask

When connecting the display to a LAN switch in order to operate the display in an existing LAN segment, you must adjust the display's network address to enable communication. We recommend using DHCP. However, you may also adjust the network settings manually.
