Runco VX-55D, VX-44D manual White Balance, Pre Calibration, Auto Color Enable, Back Porch

Installation

•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 which black and white are known to be at opposite edges of the image, you can watch these isolated areas while adjusting individual black and white levels until both black and white edges are just visible and distinguished from neighboring pixels. Images from this source will then display correct blacks and whites without crushing.

Figure 3-20. Adjusting Black Levels and White Levels Using the Clipping Detector

1.Display a 16-level grayscale test pattern from the DHD Controller.

2.Enter a checkmark in the Clipping Detector checkbox.

Note	The Clipping Detector will initially render the grayscale as a uniform
	gray field before adjustment or extreme crushing.

3. Display one primary color.

Tip	Selecting Auto Color Enable ensures that the correct color is
	displayed for each setting.

4.For the current color, adjust its corresponding “Black Level” slidebar just until a single band of black appears at one edge of the screen. This band represents the first band of the grayscale pattern, which should be 100% black. Do not adjust too far.

5.With the same color still active, adjust its corresponding “White Level” slidebar just until a single band of color appears at the opposite edge of the screen. This band represents the last band of the grayscale pattern, which should be 100% white (or the current color, if a certain color is enabled). Do not adjust too far.
