Auto SetupUse the Auto Setup feature of the Vision 140/150 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...

For 1080i digital and 1080p signals, channels are pre-configured at the Vidikron factory for 
each aspect ratio. These channels use Custom size presets to achieve the selected aspect 
ratio. 
• “Custom” Resizing: The “Custom” re-size descriptor automatically appears in the Size 
and Position menu when any of the values for Size, Height, Horizontal Shift, Vertical Shift 
or Blanking do not correspond to those for a preset. This...

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...

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...

• Black Levels and White Levels: To check your image and adjust these controls: 
1. Make sure overall “White Level” (contrast) and “Black Level” (brightness) settings are 
both set to near 50. (Not required for “Pre-Calibration” adjustment.) 
2. Check the color temperature setup using an internal grayscale test pattern, making 
sure to obtain a neutral grayscale. (Not required for “Pre-Calibration” adjustment.)
