For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of black
and white pixels, or a similar “half on, half off” graphic image. Adjust the slidebar until the image
stabilizes and each pixel is clearly defined. You may notice that you can stabilize the image at more
than one point. Use either setting in such cases.
Clocks (VGA sources)
This control sets the frequency of the pixel sampling clock, indicated by the number of incoming
pixels per line, so that all pixels generated by a particular source are sampled.
Steady flickering or several soft vertical stripes or bands across the entire image indicates poor
pixel tracking. Proper pixel tracking helps ensure that the image quality is consistent across the
screen, that aspect ratio is maintained and that pixel phase (see above) can be optimized.
VGA ADC Settings
Select VGA ADC Settings from the Advanced Settings menu to calibrate the display’s analog-to-
digital converter (ADC) for VGA sources.
Flesh Tone
Select Flesh Tone from the Advanced Settings menu to lighten or darken the flesh-colored areas of
the image. (This setting is only available with Video sources.)
IRFM
Select IRFM from the Advanced Settings menu and press or to enable or disable this feature,
which creates slight frame motion to help avoid image retention.
Baud Rate
Select Baud Rate from the Advanced Settings menu and press or to set the data rate of the
RS232 communication link.
Smart Light Control
Select DCR to enable the Dynamic Contrast Ratio feature. DCR lowers the backlight for dark scenes
and increases the backlight for bright scenes. DCR improves apparent contrast but is not ideal for
all content, since modulation of the backlight may be visible.
Select Light Sensor to enable the ambient light sensor feature. Light Sensor automatically adjusts
the brightness of the display according to room (ambient) lighting.
Wake Up From Sleep
Select Wake Up From Sleep from the Advanced Settings menu and press or to control this
feature, which operates as follows:
• VGA Only: The display wakes up from power-saving mode when it receives an active video
signal on its VGA (analog) input.
• VGA, Digital, RS232: The display wakes up when it receives an active signal from its VGA,
HDMI, Display Port or DVI inputs, or receives a valid RS232 command.
• Never Sleep: The display never enters power-saving mode.
