Chapter 6 Troubleshooting
Possible cause and remedy
• Check that the monitor and PC are connected with a USB
cable.
• Check that the power cord of the monitor and PC is
connected to a grounded main outlet. Failure to ground
the equipment may result in malfunction.
• Connect the monitor to the PC with the cable indicated in
the Setup Manual. The touch panel may not work correctly
if a conversion adapter is used.
• Turn off and on the monitor.
• Calibrate the screen again.
• Check that the power cord of the monitor and PC is
connected to a grounded main outlet. Failure to ground
the equipment may result in malfunction.
• Changing the position or angle of the monitor may cause
the cursor to jump.
• If the touch panel is dirty, the touch panel may not operate
properly. Refer to the User's Manual of the monitor to
clean the touch panel.
• The spray for preventing static electricity may influence
the sensitivity of the touch panel.
• Do not touch the touch panel for 5 seconds after the PC
starts up, after turning on the monitor, or after connecting
the USB cable. Touching the touch panel too soon may
cause incorrect cursor positioning or disable touch
operation. If this occurs, either leave the touch panel
untouched for approximately 2 minutes or turn the monitor
off and on again. If the problem persists, calibrate the
screen again.
• Changing the screen size of the monitor may cause the
cursor position to become misaligned. Execute calibration
again after changing the screen size.
• When displaying at a resolution other than the
recommended resolution, the touch position and cursor
position may shift due to the scaling function of the
graphics board.In that case, check the graphics driver
settings and change the scaling to the monitor.After
changing the settings, perform calibration again.
• Calibrate the screen again.
• Reset the touch panel to the state before calibration (by
clicking "Reset" in the "Display" tab of the "Tablet PC
Settings" window accessible from the Windows Control
Panel) and then calibrate the touch panel again.
• Once "Setup" has been completed in the "Display" tab
of the "Tablet PC Settings" window accessible from the
Windows Control Panel, close the "Tablet PC Settings"
once, open the "Display" tab of "Tablet PC Settings" again,
and then attempt calibration.
