Output Mode – Global Presets
This command is not generally needed. However, it can be useful when driving displays that do not report EDID
and where no video is visible until a specific format is sent. It changes the
Output Mode for all Inputs and input
memories. Select the Output Mode from the table below. The command is:
MENU → → → → Output → → → → Custom Modes→ → → → [Custom] → → → → Select Mode → → → → OK
The direct commands to select output resolution are:
480p60: MENU 0 2 1 OK 540p60: MENU 0 2 2 OK
720p60: MENU 0 2 4 OK 768p60: MENU 0 2 5 OK
1080p60: MENU 0 2 7 OK
Exact Output Timing
After selecting a Custom Output Mode, its timing can be modified on a pixel basis. Do not change the timing using
this menu unless it is really needed. Some digital displays lose picture if timing is changed by even a single pixel.
The command is:

Mode Timing
CMS Menu
The Color Management System (CMS) stores settings used to calibrate the color of the display. There are menus to
calibrate the position of the primary/secondary color points, calibrate grayscale tracking, calibrate the gamma
curve, and compensate for red/green push errors.
Gamma Factor
The Gamma Factor adjusts the gamma of the video output up or down. Since the Radiance is in the middle of the
video chain, its default goal is to not affect the image Gamma and so the default Radiance gamma is 1.00.
Changing the Gamma Factor allows the Radiance a “coarse correction” control for display Gamma. It should be set
to (Desired_Gamma / Measured_Gamma). The command is:
MENU →
→ → →
Output →
→ → →
CMS’s →
→ → →
[CMS] →

→ → →
OK
Color Gamut
Allows primary and secondary color point calibration, or calibration of 729-points throughout the linear-Gamma
RGB color cube, using a linear-Gamma 3D color lookup table. A color probe and appropriate calibration software is
necessary for proper adjustment. The command is:
MENU →
→ → →

Color Gamut
Grayscale and Gamma
Allows the parametric adjustment of 2, 5, 11, 12 or 21 color temperature points to adjust the grayscale and
gamma for the display. The command is:
MENU →
→ → →

Gray/Gamma
Color Decoder
Used to correct color decoder errors in the display that have red and/or green push. This adjustment should
generally
not be used in conjunction with Color Gamut. The command is:
MENU →
→ → → Output →
→ → → CMS’s →
→ → → [CMS] →
→ → → Color Decoder
Black Level
Used to set the black level for the display. Normally the “Brightness” or “Black Level” control in the display is used
to set the black level. However, some displays cannot be set accurately. This command allows for accurate
calibration when the display controls are not adequate. It is recommended that the Radiance Contrast Pattern 2
(dark contrast) be used to set the display’s black level. This command is also useful when a second black level is
desired (using a second output CMS) for a “day” or “night” mode. The command is:
MENU →
→ → → Output →
→ → → CMS’s →
→ → → [CMS] →
→ → → Black →
→ → → Ok
