I have a problem with touch response.
Problem
Touch does not respond.
The location of a touch does
not correspond to the touch
coordinates.
Touch coordinates appear to be
rotated 90 degrees (Windows
XP).
I cannot start LG TDS.
Check the USB cable connection.
- This may occur when the USB cable between PC and monitor is not
connected. Check the USB cable and make it firmly connected.
* Check the connection on Windows 7
Control Panel > System and Security > System
- Check the number of touch-points supported under Pen and Touch.
* Check the connection on Windows XP
Go to Control Panel > System > Hardware > Device Manager >
Human Interface Devices.
You need to be able to see LGE MultiTouch Device on the USB
Human Interface Device Properties window.
Check the PC power.
- This may occur when the PC is powered off. Make sure that your
PC's power cord is firmly plugged into a power outlet.
Restart your PC.
- Touch may not respond when the system is down due to the unstable
network. Reconnect the LAN cable or restart your PC.
Check the signal cable connection.
- If your PC and monitor are not connected using a signal cable, touch
does not respond. Check the signal cable connection.
Check the monitor power.
- Touch may not respond when the monitor is powered off.
Check if the screen is currently on.
Change your tablet PC settings (Windows 7).
- This may occur when the touch screen is not calibrated properly.
Control Panel > Hardware and Sound > Tablet PC Settings > Display
> Display options > Calibrate or Reset
* For information about gestures and settings on Windows 7, refer to
the Windows Help.
Change the display setting to Full Screen (Windows XP).
- On Windows XP, rotation of touch coordinates works only in full
screen mode.
* Refer to help of the graphic card installed on your PC.
Change the Screen Rotation setting with LG TDS.
- Run the LG TDS provided with the monitor and set to Landscape or
Portrait.
When using HDMI, set the Input Label to PC.
Check whether the operating system is Windows XP.
- LG TDS is supported only in Windows XP.
Install .NET Framework 3.5 or later.
