Standard settings are:
 9300K, is close to the white of many computer monitors
 6500K, is the standard for color video, in both standard and high definition forms
 5400K, is a standard for graphics and black and white video
 3200K, is useful if the projected image is to be filmed or shot as part of a studio set illuminated with
incandescent lights
For all color temperatures the color primaries; red, green, and blue are unchanged and reflect the native colors
of the projector.
SD Video and HD Video - Sets the output color to a specific standard value. Adjusts the colors; red, green,
blue, and white.
User# - Select 1 of 4 user defined sets of color adjustments; defined in the Configuration menu.
IRIS - S
UBMENU
The Iris adjusts the aperture to allow more or less light through. This will allow for deeper blacks in dark
scenes.
• ENABLED
The Enabled control has options Off, Manual, and Per Channel. Think of this control as a global override.
The Iris is either Off (fully open), set to a manual % open position, or it is up to the channel to determine the
Iris position. When Enabled is set to Per Channel, the Mode control becomes enabled. This control has the
options Off, Manual, or Dynamic. If manual is selected, the Iris Position control becomes a per channel
control (instead of a global control).
Channel".
• IRIS POSITION
Set the fixed manual Iris position as a percentage of fully open.
• SENSITIVITY
Adjusts how sensitive the Dynamic Iris control algorithm is to small bright objects entering and leaving an
image, such as stars or candles. With a lower sensitivity value these small bright objects are more likely to be
ignored, producing a more stable light level for the image, with the side effect that some detail in those bright
objects will be lost. It is often best to adjust the sensitivity and white compression together to find the optimal
settings.
• OPEN SPEED
The open speed of the Iris represents the maximum Iris change per frame. Increasing this value will allow the
Dynamic Iris to travel further in a frame. Decreasing this value will allow for a more gradual change. A slower
value will reduce any flicker in the image, but it will also mean that the Dynamic Iris will not react quickly to
a scene that suddenly becomes much brighter; resulting in a image that will show a significant loss of detail for
several frames.
• CLOSE SPEED
The close speed of the Iris represents the maximum Iris change per frame. Increasing this value will allow the
Dynamic Iris to travel further in a frame. Decreasing this value will allow for a more gradual change. A slower
value will reduce any flicker in the image, but it will also mean that the Dynamic Iris will not react quickly to
a scene that suddenly becomes much darker, resulting in an image that does not have as much contrast as it
could for several frames.
