• Advanced: For more precise white balance control, use Advanced mode to create
a “custom” color gamut and color temperature. You do this by specifying x/y
coordinate values for each primary color point (red, green and blue) and the white
point.
The default values (shown here) are the RGB color space parameters defined in
ITU-R Recommendation BT.709. You can adjust them up or down by a factor of
0.100; for example, the “Red x” range is from 0.540 to 0.740.
The Auto Color Enable and Test Pattern Enable checkboxes let you choose
what to display on-screen while making these adjustments. These controls work
together as follows:
• RVR: Use the RVR control to increase or decrease the Reflectance Volume Regulation
setting. RVR lets you control 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 higher setting for rooms with a lot of ambient light. Use a lower setting for more
“theater-like” viewing conditions (little or no ambient light).
