■Color Temperature
Use this setting to choose one of three color temperature presets:
• D55 (5500K)
• D65 (6500K)
• D93 (9300K)
• USER (Adjustable Color Bias and Gain)
• Linear (No processing is applied to the panel)
Use this setting to enable monochrome mode. Only the luminance of the image will be displayed as a grayscale
picture.
■RGB Bias and Gain
Select this submenu to fine-tune the monitor’s color balance (R, G, B). This should only be done by someone
experienced with video engineering, as this will alter the overall color shading of the screen. The purpose is to
allow color matching to other types of monitors and/or displays. Note: The Color Temperature preset will
automatically switch to USER when Color Bias settings are adjusted. It is normal for color bias adjustments to
be very subtle.
When selecting the RGB Bias and Gain submenu, gain adjustment indicators will appear at the top of the
screen, and bias adjustment indicators will appear at the bottom of the screen:
Use the ▲and ▼buttons to select each individual bias or gain control. Press SELECT to begin adjusting the
control. Use the ▲and ▼buttons to increase or decrease the value.
Alternately, the image adjustment buttons (Brightness, Color, Tint, Contrast) can be used to easily adjust the bias
and gain settings as shown below. The buttons affect whichever row of controls (gain or bias) is currently selected.
■Check Field
Use the check field modes for monitor calibration or to analyze individual color components of an image. In
Monochrome mode, all color is disabled and only a grayscale image is shown. In Blue, Green, and Red check
field modes, only the selected color will be shown.
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
button until there is no visible difference between the super black and black bars, but the gray bar is still visible.

5. Adjust the Contrast button until an even grayscale appears along the top bars.
6. Disable Monochrome mode.
7. Enable Blue Check Field mode and adjust the Color button so that the outermost bars (white and blue) appear to match in
brightness.
8. Composite NTSC only: Adjust the Tint button until the third bar from the left (cyan) and the third bar from the right (magenta)
appear to match in brightness.
9. Disable Blue Check Field mode.
■Ratio Settings
Use to switch between Full Screen, 4:3 and 16:9 aspect ratios.
As the V-MD702 monitor has a native resolution of 800 x 480 RGB pixels, incoming images are automatically
scaled to fit the screen:
• In Full Screen mode, images are scaled to fill the entire screen (800 x 480).
• In 4:3 mode, images are scaled to fill the center 4:3 portion of the screen (640 x 480). With a 16:9 source,
images will be centered with a black letter-box added on the left and right sides.
• In 16:9 mode, images are scaled to a 16:9 portion of the screen (800 x 450), with a black letter-box added
top and bottom.
Note: The aspect ratio setting is ignored when Pixel-to-Pixel mode is enabled.
■Pixel-to-Pixel
Use this setting to enable Pixel-to-Pixel mode.
This Pixel-to-Pixel mode bypasses the monitor’s internal scaling function and displays incoming images in their
native resolution and aspect ratio, with a one-to-one mapping:

V-MD702 Operating Instructions
11
• For incoming formats smaller than the native resolution of the LCD panel (800 x 480), the image will be
displayed in the center of the screen using only the necessary LCD pixels. For example, NTSC images will
occupy exactly 720 x 480 pixels. The surrounding pixels will be black.
• For incoming formats exceeding 800 x 480 pixels, only the center 800 x 480 of the incoming image will
displayed occupying the whole screen, with the remainder of the picture cropped. For example, 1080i
formats will both be cropped to 800 x 480 and displayed full-screen.
Note: Pixel-to-Pixel mode disables aspect ratio control and H/V Delay.
Marker Configuration Submenu
■Markers
Use this setting to enable or disable all on-screen markers. This setting affects the center marker, full screen
markers, 16:9 markers and 4:3 markers.
■Center Marker

• 25% Image area beyond the marker is shown at 25% intensity.
• 50% Image area beyond the marker is shown at 50% intensity.
• 75% Image area beyond the marker is shown at 75% intensity.
• 100% Image area beyond the marker is shown at 100% intensity (black).

Filter Configuration Submenu
■False Colors
The V-MD702 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).

■Mosquito Filter
Use this setting to filter out “Mosquito Noise” – an artifact that appears as specs around edges of objects. This
artifact is the result of video that has been compressed at some point. Video sources from DVD-Players, PDA’s,
Digital Cable Boxes, Camcorders, etc. often have this artifact.
