Installation and Initial Setup
■Unpacking
Carefully unpack the V-LCD70MD monitor and verify that the following items are included:
• V-LCD70MD Monitor
• V-PS12V-2A-R/APower Supply
• Operating Instructions
Inspect the unit for any physical damage that may have occurred during shipping. Should there be any damage, immediately
contact Marshall Electronics at [phone]. If you are not located within the continental United States, call +1 (310) 333-
0606.
■Connections, Power-On and Initial Setup
Plug the power supply into an AC power source (100-240 V @ 50/60 Hz). Attach the Power connector to the back of the monitor.
Connect the required cables for video signal input and output. (Power must be applied to the V-LCD70MD for the active loop-
though output to be activated.) The monitor defaults to ‘ON’ when power is supplied. Video will automatically be detected and
displayed on the screen.

Scaling Submenu

11
When you are satisfied with the position, press the SELECT button or press the BRIGHT knob to confirm your selection.
The new cropped selection will be displayed on the screen. If your Aspect Ratio is set to AUTO, the monitor will select
the closest aspect ratio to the dimensions of your customized Input.
■Aspect Ratio
Use this menu option to switch between several aspect ratio settings.
• In 4:3 mode, images are scaled up or down to fill the maximum 4:3 portion of the screen.
• In 16:9 mode, images are scaled to fill the entire 16:9 screen.
• In Full Screen, images are scaled to fill the entire screen.
• In Custom mode, images scaling is adjusted to your selection in the Adjust portion of the menu:
Adjust
Use any of the rotary knobs to select your desired aspect ratio. Some of the more common aspect ratio
settings are shown on the Aspect Ratio selection widget. As you move along the scale, your current aspect ratio will be
displayed below the widget.

■Pixel-to-Pixel
Use this setting to enable Pixel-to-Pixel mode.
This mode bypasses the monitor’s internal scaling function and displays images in their native resolution and aspect ratio, with a
one-to-one mapping of incoming image pixels to screen pixels:
• For incoming formats smaller than the native resolution of the screen (or selected aspect ratio), the image will be
displayed in the center of the screen using only the necessary LCD pixels. For example, 720p images will occupy exactly 1280x720
pixels in the center of the screen. The surrounding screen area will be black.
To select a Custom Pixel to Pixel zone, enter the Adjust function:
Adjust
Custom Aspect Ratio selection

The outer square represents the entire image and the inner grey box represents your current Pixel to Pixel selection.
Use the COLOR knob to move your selection LEFT and RIGHT. Use the CONTRAST knob to move your selection UP or DOWN.
Press the SELECT button or the ROTOMENU knob to lock in your selection.
■DSLR Preset
Use the DSLR Preset option to reduce the visibility of on screen indicators shown with popular DSLR cameras. The available
options are :
• NK 16:9
• NK 3:2
• CN 16:9
• CN 3:2
Color Submenu
■Temperature
Use this setting to choose one of three color temperature presets:
• D55 (5500K)
• D65 (6500K)
• D93 (9300K)
• Custom (Adjustable Color Bias and Gain)
• Linear (No processing is applied to the panel)
■Bias & 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 Custom when Color
Bias settings are adjusted. It is normal for color bias adjustments to be very subtle.
IMD Configuration Submenu

14
When selecting the RGB Bias and Gain submenu, bias adjustment indicators will appear at the top of the screen, and gain
adjustment indicators will appear at the bottom of the screen:
Use the ▲and ▼buttons to select each individual bias or gain control. Highlighting the BIAS or GAIN icons enables a group
change of the Red, Green and Blue color components, respectively. Alternatively, you can use the BRIGHT knob to scroll through
the different color components and settings.
After selecting the color component to adjust, use the ▲and ▼buttons to increase or decrease the value.
■Gamma
Use the Gamma setting to adjust the value of the gamma applied to incoming video signals. The default gamma value is 2.2.
Gamma correction represents the relationship between the pixel levels from your incoming video and the luminance of your
monitor. The lowest gamma level available, 1.6, will cause the image to appear brighter. The highest gamma level available, 2.4,
will cause the image to appear darker. The chart below shows this on a scale.

control the LEFT, RIGHT, TOP and BOTTOM edges, respectively.
Each Marker (1 or 2) can be fully customized in this fashion.
■Line Width
Use this setting to choose the width of the marker lines, from 1 px (thinnest) to 10 px (widest).

17
■Line Color
Use this setting to select a custom color for the Screen Markers. You can choose between White (default), Yellow, Red,
Green and Blue.
■Transparency
Use this setting to select the transparency of the marker background. Choose between 0% (black) , 25%, 50%, 75% and
100% (see through) transparency.
Filters Submenu
Use the Filters Submenu to enable various modes.
■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 knob until there is no visible difference between the super black and black bars, but the gray bar is still
visible.

18
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.
8. Disable Blue Check Field mode.

■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.
