Common Installation Issues
Possible Solutions
Touch screen does not respond
to touch
•
Review the installation procedures. Are all cables
connected properly?
•
After you installed TouchWare, did you restart your
PC to activate the touch screen driver?
•
Are the communication settings correct? Is the touch
screen 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
screen will not work.
Touch screen is not accurate
Calibrate the touch screen 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 screen for the current video resolution
and operating system.
Cursor is not located directly
underneath your finger
•
Open the touch screen control panel and make sure
all cursor offsets (vertical, edge/horizontal) are turned
off.
•
Calibrate the touch screen 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 screen controller.
Cursor lags finger
Lower the baud rate of the touch screen controller and the
touch screen driver.
Power Management
The ChassisTouch monitor conforms to the Video Electronics Standards
Association (VESA) Display Power Management Signaling (DPMS)
standard. To benefit from power management, the monitor 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 screen, 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.
