output timing differences among various VGA cards in the market, users may initially
experience an unstable or unclear display whenever a new display mode or new VGA card is
selected.
Important:
This LCD monitor supports multiple VGA modes.
Refer to the standard Timing Table for a listing of modes supported by this LCD monitor.

The screen has defective
pixels (e.g. slightly light or

the LCD monitor.
Incorrect display of colors If any colors (red, green, or blue) are missing, check that
the signal cable is firmly connected. Damaged pins in the
cable connector may also result in a faulty connection.
