Enabling Auto Adjust [Auto Adjust]
When “Auto Adjust” is set to “On”, the projector automatically determines
the best resolution for the current RGB input signal to project an image
using NEC’s Advanced AccuBlend Intelligent Pixel Blending Technology.
The image can be automatically adjusted for position and stability;
“Horizontal Position”, “Vertical Position”, “Clock” and “Phase”.
On .................. Automatically adjusts image “Horizontal Position”, “Ver-
tical Position”, “Clock” and “Phase”.
Off .................. User can adjust the image display functions (“Horizon-
tal Position”, “Vertical Position”, “Clock” and “Phase”)
manually.
Adjusting Position/Clock (when Auto Adjust is off)
This allows you to manually adjust the image horizontally and vertically,
and adjust Clock and Phase.
[Horizontal/Vertical]
Adjusts the image location horizontally and vertically.
This adjustment is made automatically when the Auto Adjust is turned
on.
[Clock]
Use this item with the “Auto Adjust off” to fine tune the computer im-
age or to remove any vertical banding that might appear. This function
adjusts the clock frequencies that eliminate the horizontal banding in
the image. This adjustment may be necessary when you connect your
computer for the first time. This adjustment is made automatically when
the Auto Adjust is turned on.
[Phase]
Use this item to adjust the clock phase or to reduce video noise, dot
interference or cross talk. (This is evident when part of your image
appears to be shimmering.)
Use “Phase” only after the “Clock” is complete.
This adjustment is made automatically when the Auto Adjust is turned
on.
Turning On Noise Reduction [Noise Reduction]
Reduces video noise.
NOTE: The lower the Noise Reduction level, the better the image quality by way
of higher video bandwidth.
Turning On Flicker Reduction [Flicker Reduction]
Reduces flicker which can occur in an interlaced signal.
NOTE: When the Flicker Reduction is ON, jagged lines can be visible depending
on the signal. In that case, select OFF.
Adjusting White Balance [Brightness R/G/B, Contrast R/G/B]
This allows you to adjust the white balance. Brightness for each color
(RGB) is used to adjust the black level of the screen; Contrast for each
color (RGB) to adjust the white level of the screen.

in “Base Setting”.
