Touch screen troubleshooting

NOTE: For general troubleshooting information, refer to the HP LCD Monitors Reference Guide

included on the disc with your monitor.

Table 3-2 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.

Windows 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.

Multi-touch gestures do not function on Windows 7 Home

Basic or Starter editions, Windows Vista, or Windows XP.

Only Windows 7 Home Premium, Professional, Enterprise,

and Ultimate editions support multi-touch gestures.

The Start, Close, and other icons are too small to touch with

a finger.

Windows 7 provides a large icon feature that supports touch

screen functions. This feature can be accessed in the Control

Panel. A stylus may also be used.

Touch operation does not function properly on lower-

resolution video modes that are not displayed in fullscreen.

Although the monitor supports a fill-to-aspect ratio function, the

touch controller does not know how to respond to less-than-

fullscreen images. Either change the resolution to 1920 x

1080, or access the OSD menu and select Image Control

to enable Fill-to-Screen (default setting).

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.

NOTE: Windows 7 Home Basic and Starter editions,

Windows Vista, and Windows XP do not support extended

display touch functionality. They support single-touch functions

on the primary monitor only, not the secondary monitor

(extended or cloned desktop).
