Possible tests or solutions
• Check the VGA jumper settings on the
display controller
• Check the CMOS settings in the PC
BIOS
• The User Controls may be disabled.
Please read the paragraph about the
"User Controls" function.
• Select another resolution in the
Windows "Display Properties" control
panel
• Switch the "Scaling" function
(Geometry menu) in the display OSD
to "None" or "Best Fit"
• Select another resolution in the
Windows "Display Properties" control
panel
• This phenomenon, called "image
sticking" is normal if the same image
has been on the screen for a long
time. The ghost image will disappear
after some time.
Over 10 hours operation with the
same image content is not
recommended. Switching on the
display DPMS may decrease the risk of
image sticking.
• A slight case of image sticking can be
solved by continuously displaying a
full white image during a number of
hours.
• Switch the video cables at the display
controller or at the display video
inputs
