Use the following procedure when calibrating the monitor to SMPTE color bars with the following procedure:
1. Allow the monitor to warm up for at least 5-10 minutes.
2. Display SMPTE split-field color bars on the monitor using an external source.
3. Enable Monochrome mode.
4. Locate the pluge pattern (super black, black, and gray bars) at the lower-right corner of the screen. Adjust the Brightness knob until there is no visible
difference between the super black and black bars, but the gray bar is still visible.
5. Adjust the Contrast knob until an even grayscale appears along the top bars.
6. Disable Monochrome mode.
7. Enable Blue Check Field mode and adjust the Color knob so that the outermost bars (white and blue) appear to match in brightness.

■False Color
This monitor has a false color filter to aid in the setting of camera exposure. As the camera Iris is adjusted, elements of the image will change color based on the
luminance or brightness values. This enables proper exposure to be achieved without the use of costly, complicated external equipment. To best utilize this feature, you
must understand the color chart below and have a basic understanding of camera exposure. Normally, when shooting subjects like people, it is common practice to set
exposure of faces to the equivalent of approximately 56 IRE. The false color filter will show this area as the color PINK on the monitor. Therefore, as you increase
exposure (open the IRIS), your subject will change color as indicated on the chart: PINK, then GREY, then a few shades of YELLOW. Over exposed subjects (above 101 IRE)
on the monitor will be shown as RED. In addition, underexposed subjects will show as DEEP-BLUE to DARK–BLUE, with clipped-blacks indicated with a FUCHSIA-like color.
Lastly, the color GREEN is used to indicate elements of the image that are approximately 45 IRE. This represents a ‘neutral’ or ‘mid-level’ exposure commonly used for
objects (not people).
False Color Key

■Peaking (Focus assist)
The Peaking Filter is used to aid the camera operator in obtaining the sharpest possible picture.
You can turn the Peaking filter ON and adjust the Threshold and Color by accessing the Adjust function. Use the BRIGHT knob to adjust the Threshold. Adjusting the
Threshold to a higher value forces the Peaking algorithm to react quicker to objects that are in focus. Use COLOR knob to adjust the Color. Your choice is are Red
(default), Yellow, Pink, Green and Blue.
■Clip
The Clip function is used to visually filter data on the screen that is under a Lower Threshold or over an Upper Threshold. Data on either side of the filters can be filtered
with a custom color.
The Lower Threshold numerical value and color can be adjusted using the BRIGHT and COLOR knob, respectively.
The Upper Threshold can be adjusted using the CONTRAST and USER knob, respectively.
In the image above, the Lower Threshold has been set to 20 IRE (Red). This means that any part of the image UNDER 20 IRE will be “colored” in RED. Also, the Upper
Threshold has been set to 90 IRE (Yellow). This means that any part of the image OVER 90 IRE will be “colored” in YELLOW.
■Invert
The Clip function can also be inverted to filter the area between the Upper and Lower Threshold. The color selected for the Lower Threshold acts as the color for
all inverted Clip data.
In the image above, the Lower Threshold is set to 20 IRE and the Upper Threshold is set to 90 IRE. The Clip Invert will filter all data in between 20 IRE and 90 IRE and
color it RED.
■Monochrome

17
Enabling Monochrome in the Clip filter will convert all video to monochrome first, and then apply the Clip filter. This helps visually filtered data stand out from
regular color video.
■Apply To Waveform
Enabling Monochrome in the Clip filter will convert all video to monochrome first, and then apply the Clip filter. This helps visually filtered data stand out from
regular color video.
