The XX0X-LCD series monitors support the video timings listed above. There
are many different video cards and video signal formats in gaming and
industrial applications. In general, the video signal of various VGA cards are
compatible with VESA recommendations, but many legacy gaming machines
are not. The Ceronix XX0X-LCD is designed under the assumption that every
video signal is standardized, therefore some signals may not lock in perfectly
during auto-signal detect. To avoid this compatibility issue, the Ceronix XX0X-
LCD has been tested with popular VGA cards and various gaming machines.
The compatibility can be up-dated as soon as a new signal can be evaluated.
The following procedure should be followed if the controller board is not
displaying an image correctly.
It is best to display an image that has a full window of active video. This allows
the monitor to detect and center the image on the display.
If the image does not fill the screen and center itself after power up, press the
“SELECT” button. The display will attempt to adjust the image so that it fills the
screen. If the image is centered and fills the screen, try recycling the power to
the display. If the image appears centered and fills the screen, then the auto-
detect functioned properly.
