• Intensity: To maintain a constant brightness level, select Mode from the Lamp
menu and set it to Intensity. Then, select Intensity from the Lamp menu to specify
the desired brightness level. The projector automatically adjusts the amount of
power applied to the lamp as needed to maintain the desired brightness level. The
default Intensity setting, 0%, holds brightness equivalent to 300W constantly.
•ConstantContrast: Select ConstantContrast from the Display Color - Projector
Settings menu to enable (On) or disable (Off) ConstantContrast in the optical engine.
ConstantContrast uses a dynamic iris that modulates light to the DMD based on the
actual content of the video material. Runco recommends that you disable
ConstantContrast before adjusting Brightness, Contrast or other image settings, or if
you change the RVR setting (see below) to something other than the default value.
•RVR: Use the RVR control to increase or decrease the Reflectance Volume Regulation
setting. RVR lets you adjust the aperture or iris size (the physical opening through the
lens; similar to an “f-stop” on a camera). Doing so allows you to optimize brightness
and contrast according to the amount of ambient light in the viewing area.
Use a lower setting (larger aperture = higher brightness) for rooms with a lot of ambient
light. Use a higher setting (smaller aperture = higher contrast) for more “theater-like”
viewing conditions (little or no ambient light).
• Engine Configuration: By default (and by design), the D-113d produces 2D images
that are almost twice as bright as 3D images. If this is not desirable, choose Engine
Configuration from the Display Color - Projector Settings menu and set it to Single.
With this setting, the difference in brightness between 2D and 3D modes is much less
noticeable.
Input Image: The Input Image controls are functionally similar to those in the Picture
menu (refer to page 67), but are accessible only by entering the Calibration menu
passcode.
You cannot use ConstantContrast and RVR at the same time (both
controls affect the aperture size, in different ways). Generally, using
RVR to set the total image brightness produces more satisfying
results than using ConstantContrast.
The Input Image settings establish the “zero point” for the Picture
menu settings, whose values represent offsets from the Input
Image settings. For example, if you set Brightness to 10 in this
menu, setting Brightness to 10 in the Picture menu results in an
actual setting value of 20 (10+10).
