On-Screen Menu (continued)
■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 knobs (Brightness, Color, Tint, Contrast) can be used to easily adjust the bias and gain
settings as shown below. The knobs affect whichever row of controls (gain or bias) is currently selected.
Note: RGB Gain and Bias is disabled when Color Temperature is set to Linear.
■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.
■Ratio (Aspect Ratio Settings)
Use to switch between Full Screen, 4:3 and 16:9 aspect ratios.
As the V-MD171X monitor has a native resolution of 1920 x 1200 RGB pixels, incoming images are automatically
scaled to fit the screen:
• In Full Screen, images are scaled to fill the entire screen.
• In 4:3 mode, images are scaled to fill the maximum 4:3 portion of the screen, with black bars filling the remainder
of the screen edges.
• In 16:9 mode, images are scaled to fill the maximum 16:9 portion of the screen (1920 x1080), with black bars
filling the remainder of the screen.

On-Screen Menu (continued)
Note: The aspect ratio setting is ignored when Pixel-to-Pixel mode is ON.
■Pixel-to-Pixel Mode
Use this setting to enable Pixel-to-Pixel mode.
This 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:
• For incoming formats smaller than the native resolution of the LCD panel (1920 x 1200), 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.
Note: Pixel-to-Pixel mode disables aspect ratio control and H/V Delay.
■H/V Delay
Use this setting to enable one of three delay modes (H & V Delay, V Delay, H Delay):
• In H & V Delay mode, both horizontal sync and vertical sync are delayed, resulting in both horizontal and vertical
blanking periods being shown on the screen.
• In V Delay mode, vertical sync is delayed so that the vertical blanking period is displayed on screen.
• In H Delay mode, horizontal sync is delayed so that the horizontal blanking period is displayed on the screen.
Notes: H/V Delay is disabled when Pixel-to-Pixel mode is ON.
H/V Delay is only available with Composite inputs (NTSC or PAL)
■Underscan
Use this setting to enable or disable Underscan mode:
• When Underscan is OFF, the active portion of the video signal is displayed on the screen, with 0% overscan.
• When Underscan is ON, the image size is slightly reduced. This allows the user to clearly view the edges of the
active video area.
Note: Underscan is only available with Composite inputs (NTSC or PAL)

submenu and press the SELECT button. You may also begin with an already predefined safe area (95%, 93%,
90%, etc.) and make your adjustments from there by highlighting a particular safe area and pressing the SELECT
button.
2. Use the BRIGHT, COLOR, TINT and CONTRAST knobs to move the LEFT, RIGHT, TOP and BOTTOM
borders of the safe area to your desired position. When you have reached the desired location for the borders,
press the MENU button. If you began the marker adjustment using one of the predefined safe areas and made
an adjustment, the marker selection will automatically convert to the User marker setting.

FILTER CONFIGURATION SUBMENU
■False Colors
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).
