Touch Screen Troubleshooting Tips

Problems
Computer does not recover
from sleep mode when the
touch screen is touched
The USB cable is quickly
removed from the monitor
then reinserted, the touch
function may be lost.
The two-touch operation
and some gestures do not
function on Windows Vista
or XP operating systems.
The Start, Close and other
icons are too small to touch
with a finger.
Touch operation does not
function properly on lower
resolution video modes
that are not displayed in
full screen.
A single touch is recognized
as two touches. If using a
paint tool, a single finger
creates two lines.
When the monitor used is
in a dual-screen
configuration, the touch
function on the second
display does not work.
Note: Never disassemble or repair the product yourself. If your problem cannot be solved
according to the troubleshooting guidelines, please contact your local dealer.

Possible Solutions
Sleep mode recovery is not supported by the touch screen. Use
the keyboard or mouse to recover from the computer 's sleep
mode.
Microsoft Windows takes a minimum amount of time to adjust
system parameters when a USB device is either removed or
connected. Try removing the USB connection again, wait for at
least 5 seconds then plug it in again.
Only Windows 7 Operating System supports the two-touch and
gestures functions.
Windows 7 operating sytem provides a large icon feature that
supports touch screen funtions. This feature can be accessed in
the Control Panel. A stylus may also be used.
Although the monitor supports a fill-to-aspect ratio function, the
touch controller does not know how to respond to less than full
screen images.
Either change the resolution to 1920 x 1080 or access the OSD
menu and select Image Control to enable Fill-to-Screen (default
settng).
The touch controller has limitation on the size of the "touch" area. A
finger tip touch usually works better than a flat forefinger or
thumb touch.
The USB connection is only capable of operating a single-touch
screen monitor.
