Alter the values using one of the two options:
• click the up/down buttons to increment/decrement the coordinates/value. Adjust one short click at a time, several longer clicks,
or hold the button for an accelerated movement.
• click the Launch Dialog button to the right of the x/y text regions to enter a value using the on-screen keyboard.
TCGD NOTES
You can create a new custom target by defining different coordinates for one or more TCGD colors or simply
by changing the tolerance state and then saving as a new TCGD file. For most applications, TCGD values are
used simply to verify that displayed colors actually do match the standard, i.e., you can measure each color at
the screen and compare its coordinates to those appearing in the TCGD fields to confirm that the projected
colors are accurate. For special applications in which you want to create a unique target color standard, enter
new TCGD coordinates as desired and then click the Save As button to save as a new TCGD file.
To Record TCGD Color Settings
For each color, record the native "uncorrected" x/y color coordinates measured at the screen. These values
represent the currently viewable primary colors, and collectively define the raw color performance "reference
point" for this projector in the current environment. Each color option button activates the corresponding full-
field YCbCr test pattern of this native color so that measurements can be taken. For example, to measure the
red coordinates, click the Red option button to change the screen display to full-field red and measure
coordinates at the screen. Repeat for each color, and record them in the x/y text boxes. After all colors have
been measured and recorded, click the Save button. To cancel changes and return to the previous TCGD
coordinates, leave the window without saving or click the Revert button next to the Save button.

Description
Select the Use White Clip check box when playing back content encoded with the DCI XYZ color
space. This will help bring the chromaticity of white within range with the projector without sacrificing
output brightness or contrast. To adjust the actual white clip limit, select the Use White Clip check
box and then select the radio button below the Use White Clip check box. Next, adjust the x/y values
accordingly.
The Target (TCGD) color fields show the corresponding x/y color coordinates defined for the current
target color gamut in use. See TCGD Notes below. To adjust the value of the x/y color coordinates,
click a color option button to display the x/y values for the selected color, and then change the value
based on the measurements taken from the screen. The selected color displays above x text box.
Gain indicates the luminance (a.k.a. brightness or intensity) of each color as compared to full-on white,
ranging from 0 (0%) to 1 (100%). You may want to modify one or more gain values to precisely match
color levels in other adjacent displays or to accommodate a studio's internal color management tech-
nique. Gain would rarely if ever be adjusted for theatre use.
Shows a test pattern when the color changes. Select the Display Test Pattern check box and then
select a color option button in the Gamut Visual Control region.
The chosen target for white coordinates (White XY) under Target (TCGD) may be relaxed by estab-
lishing a small "tolerance box" around it. This box represents four coordinates (0-1-2-3) plotted on a
1931 CIE Chromaticity graph and may vary from TCGD to TCGD. See White Tolerance Notes below.
Select the White Tolerance check box to enable the White Tolerance grid and x/y text boxes. To
change the value of the x/y colour coordinates measured from the screen, select one of the four corners
and then adjust the value. Values range from 0.0 to 1.0.
