QuartBox

11.141.1
Description
The primary version (shown below) has a single white box in the center of active video.
The size of the box is one-half the width and height of the active video area (a quarter of the entire active video
area). The secondary version draws a black box on a white background.
11.141.2
Test
Brightness control adjustment.
11.141.3
Purpose
The wrong brightness setting on your monitor may cause other tests such as Contrast, Focus, and Beam Size to
be invalid. An accurate brightness setting helps give repeatable measurements throughout other tests. This version
of the brightness box should be used if the display's specifications call for the brightness to be set with one-fourth of
the screen lit.
11.141.4
Method
Place your light meter probe within the center box and adjust the monitor's brightness control to obtain the required
light meter reading.
11.141.5
Notes
The color of the center box is a special color, named foreground. The FRGB command can be used to change the
default color of foreground to any RGB value.
IMGL quartbox: ALLU// loads QuartBox image
FRGB 122 122 122// sets RGB color of box
After loading a different format, send the FRGB command again to set the box fill color.
