Issues
Possible
Solutions
Touch 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 sensor driver?
•
Are the communication settings correct? Is the touch sensor trying
to use the same COM port or IRQ as another device (for example, a
mouse)? If so, a hardware device conflict will result and the touch
sensor will not work.
Touch 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 touch
sensor controller.
Cursor lags finger
Lower the baud rate of the touch sensor controller and the touch sensor
driver.
Power Management
The C1700SS 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 screen, press a key, or move the mouse. To set the period of time after
which the PC will invoke the power management feature, refer to the user manual that
came with your video card or PC.
