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.

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.
