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...

Installation 54 Vidikron Vision 150 Owner’s Operating Manual PREL IMINARY 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...

Installation Vidikron Vision 150 Owner’s Operating Manual 55 PREL IMINARY • 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...

Installation 56 Vidikron Vision 150 Owner’s Operating Manual PREL IMINARY • 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...
