• 1920x1080
– with a 2.39:1 aspect ratio applied = 1920x803. (Mathematically derived)
– with a 2.35:1 aspect ratio applied = 1920 x 817. (Mathematically derived)
– with a 1.85:1 aspect ratio applied = 1920x1038. (Mathematically derived)
NOTE: The sizes that are labeled “Mathematically derived,” were obtained using the following
methodology:
Horizontal width divided by aspect ratio = vertical height (rounded off, no decimal
places used)
Examples: 1920 / 2.39 = 803.35 (803)
1920 / 1.85 = 1037.84 (1038)
1.95 Graticules Color
The graticules may be displayed in either white or black. For most situations, white is
preferred, but in very bright scenes black may be preferable.
These are the options:
• White (default)
• Black.
1.97 Display VU Meters
This parameter allows you to enable superimposed VU meters for monitoring and
determining appropriate audio levels.
These are the options:
• Off (default)
• Horizontal
• Vertical
1.98 Histogram
The histogram provides an aid for exposure. The histogram menu parameter lets you
determine how you would like the histogram to be interpreted. The default linear
selection shows a representation of the sensor values with no interpretation or
expansion applied. Alternately, a logarithmic selection may be used that expands the
displayed data.
These are the options:
• OFF (default) – No histogram is superimposed on the monitoring outputs
• Linear – Linear mapping is used to display the sensor values
• Logarithmic – Logarithmic mapping is used to display the sensor values
NOTE: While the histogram feature serves as an accurate exposure guide during live preview or
recording, it is not representative when playing back recorded material.
