Auto SetupUse the Auto Setup feature of the VX-44d/-55d as a convenient starting point for 
calibrating the projector DVI input for optimum picture quality. 
Auto Setup is an automated process in which the projector quickly optimizes critical 
display parameters such as size, position and pixel tracking, based on...

 Pixel Phase 
 Size and Blanking 


 White Balance (Input Levels)

each aspect ratio. These channels use Custom size presets to achieve the selected 
aspect ratio.

Pixel Phase: Adjust pixel phase when the image (usually from an RGB source) still shows 
shimmer or “noise” after pixel tracking is optimized. Pixel phase adjusts the phase of the 
pixel sampling clock relative to the incoming signal. 
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...

Filter: The proper filter setting is automatically set for virtually all signals, and rarely needs 
to be changed. It applies a low pass filter for noise reduction in the incoming input signal, 
particularly for HDTV or SDTV. Applied in the analog domain before sampling, this filtering 
removes high frequencies and thus reduces pixel phase noise (note this also reduces 
signal bandwidth). Override only if standard pixel tracking and...

 Pre-Calibration: Keep off for virtually all sources (default). Temporarily enter a check 
mark only if you are an experienced technician and you have an unusual source that 
you feel needs further color temperature and/or white balance adjustment. After 
entering a check mark, wait for the six slidebar values to stabilize, then clear the check 
mark and exit. This compensates for incoming out-of-range drives (white) and black...

 Clipping Detector: The Clipping Detector is a tool to assist with defining individual 
input levels, enabling you to accurately set the white balance for any particular source 
with the appropriate image. 
Enabling the Clipping Detector activates a special operating mode for detecting only 
pixels that are considered black or white; all other levels are displayed as a mid-level 
gray. When used with a smooth grayscale pattern in...
