Touch screen tips and troubleshooting
To properly maintain the touch screen, follow these tips and troubleshooting solutions.
Touch screen tips
●
To maintain the brand new appearance of the display, clean with a soft cloth regularly. Remove stubborn
stains with a soft cleaner. Refer to
Cleaning the monitor on page 23
for detailed instructions.
IMPORTANT:
Do not use strong cleaners such as a diluting agent, benzene, or a corrosive cleaner, as
they may damage the display.
●
Never disassemble or repair the product yourself. If your problem cannot be solved according to the
troubleshooting guidelines, please contact your local dealer.
●
Retain the original packaging materials. They will be convenient if you need to transport your display
again.
NOTE:
For best protection, pack the display in the original package from the factory.
●
The touch function may need about seven seconds to resume if the USB cable is reconnected or the
computer resumes from sleep mode.
Touch screen troubleshooting
Problem
Solution
Computer does not recover from sleep mode when the touch
screen is touched.
Sleep mode recovery is not supported by the touch screen. Use
the keyboard or mouse to recover from sleep mode.
The USB cable is quickly removed from the monitor and
reinserted, and the touch function is lost.
The operating system takes a minimum amount of time to adjust
system parameters when a USB device is either removed or
connected. Try removing the USB cable again, wait for at least five
seconds, and then plug it in again.
Touch operation does not function properly on lower-resolution
video modes that are not displayed in full screen.
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. Change the resolution to the optimum resolution.
A single touch is recognized as two touches. If using a paint tool, a
single finger creates two lines.
The touch controller has a limitation on the size of the "touch"
area. A fingertip touch usually works better than a flat forefinger
or thumb touch.
When the monitor used is in a dual-screen configuration, the
touch function on the second display does not work.
The USB connection is only capable of operating a single-touch
screen monitor. If the second monitor is a touch monitor, you
must connect a second USB cable.
Touch function is erratic.
The screen may have surface contamination. Refer to
for detailed instructions.
Button lockouts
Holding down the power button or menu button for 10 seconds will lock out the functionality of that button.
You can restore the functionality by holding the button down again for 10 seconds. This functionality is only
available when the monitor is powered on, displaying an active signal, and the OSD is not active.
