Vidikron 30ET manual Operation

Operation

ICC Adjust: Use the ICC Adjust controls to customize the stored NTSC, HDTV and/or PAL color space characteristics. To do this, select the color space to modify. Then, select a component color (Red, Green, Blue, Yellow, Cyan or Magenta).

For each component color, you can adjust the following:

•Intensity: This slidebar adjusts the intensity – also known as luminance – of a given color.

•Sat. This slidebar adjusts the color saturation level -- the amount of that color in a video image. Lower settings produce less saturated colors; a setting of “0” removes that color from the image entirely. If the saturation is too high, that color will be overpowering and unrealistic.

•Hue: This slidebar adjusts the red/green color hue for true color reproduction of video signals. For best results, adjust tint while displaying an external color bars test pattern (see Figure 4-4). Otherwise, it is recommended that Hue remain at its default setting.

When you have finished customizing the color space, select Store Setting and press ENTER.

Image Over Scan: Image Over Scan pushes the outside edge of the active picture area of the video signal out beyond the edge of the display area.

Some television programs are produced based on the assumption that older television sets may not display the outer edges of the broadcast picture area. Over scan effectively trims away these inactive, outer edges and enlarges the remaining portion of the image to fill the display area.

Use the on-screen slidebar to select the desired amount of over scan.

For HDTV, DVDs and other video sources, Image Over Scan is generally not necessary or desirable.

Video Black Level: This control compensates for incoming elevated black levels present in certain video signals, and ensures that blacks in the display are neither “crushed” (where dark grays appear black) nor excessively elevated (where blacks appear dark gray). By default, the projector automatically determines the best setting according to the type of incoming video signal:

•0 IRE: Used for DVD output with “enhanced black,” SECAM, most PAL standards and Japanese NTSC.

•7.5 IRE: Used for most NTSC video signals.

For some types of video, you may want to override the setting. Generally, if black appears crushed when brightness = 30, choose “0 IRE.” If black appears excessively elevated, use “7.5 IRE.”

Image Shift: The Image Shift menu allows you to precisely center the image on the screen. (These controls are available only with a 480i source signal.)

•Horizontal: This control moves the image right or left within the area of available pixels.

•Vertical: This option moves the image up or down within the area of available pixels.

1. To adjust the image position with a 480p or higher-resolution source,

Note use the HD/RGB Adjust controls in the Option menu, described on page 44.

2.The values shown represent where the approximate center of the image lies in relation to the total number of pixels available horizontally or vertically. This varies widely according to the signal; watch the image while adjusting.
