If you are experiencing problems with the touch sensor, check the following list of 
common installation errors. 

Sensor does not respond to touch

• Review the installation procedures.  Are all cables connected 

properly? 

• After you installed touch software, did you restart your PC to 

activate the touch driver? 

• Are the communication settings correct?  Is the touch sensor trying 

to use the COM port or IRQ of another device (for example, a 
mouse)?  If so, a hardware device conflict will result and the touch 
sensor will not work. 

Sensor is not accurate 

 

• Calibrate the touch sensor for the current video resolution and 

operating system. 

Cursor does not follow finger 
movement or does not reach the 
edges of the screen 

• Calibrate the touch sensor for the current video resolution and 

operating system. 

Cursor is not located directly 
underneath your finger 

• Open the touch sensor control panel and make sure all cursor 

offsets (vertical, edge/horizontal) are turned off.

• Calibrate the touch sensor for the current video resolution and 

operating system. 

Cursor is extremely jittery or 
erratic 

• Stabilize the cursor by adjusting the operating frequency of the 

controller using the control panel. 

The M1500SS Display conforms to the Video Electronics Standards Association 
(VESA) Display Power Management Signaling (DPMS) standard. To benefit from power 
management, the display must be used in conjunction with a computer and video card 
that implements the VESA DPMS standard. 

The PC automatically invokes the power management feature if you do not use the touch 
sensor, mouse, or keyboard for a user-defined period of time.  To restore the video 
image, simply touch the sensor, press a key, or move the mouse.
