61 | NEC DISPLAY WALL CALIBRATOR - USER’S GUIDE
The Video tab is used to perform video signal and color adjustments.
The following two controls are only available when analog video inputs such as VGA, RGB/HV, and Option-
Analog. It is not necessary to re-calibrate the displays after performing these operations.
Analog Auto-Setup will measure the incoming analog video signal and automatically set the video level controls
in the display as well as the size and position of the video.
This operation should only be performed whenever a new analog video signal is connected, when a major change
is made to the video wiring to the display, or when a video amplier or splitter is added to the video link.
Note: It is essential that when this operation is performed a video signal that contains both pure black and pure white
is being input. White video should extend to each edge of the active video area, otherwise the controls may not be
adjusted correctly by the display. A sample test pattern is installed with the software and should be displayed full-
screen on the video source input.
Analog Auto Bias/Gain Setup will measure the incoming analog video signal and automatically set the video
level bias and gain controls in the display.
This operation should be performed if there is a color tint on black video after the display has been calibrated.
Note: It is essential that when this operation is performed a color bar test pattern video signal is input, otherwise the
controls may not be adjusted correctly by the display. A sample test pattern is installed with the software and should
be displayed full-screen on the video source input.
The Brightness, Contrast, Sharpness, Black Level, Tint and Color controls adjust the settings for the respective
video controls in the display.
