Installation and Initial Setup
Unpacking
Carefully unpack the V-LCD171MD monitor and verify thahe following items are included:
•V-LCD171MD Monitor (3G Module Oponal)
•V-PS12-5V-XLR Power Supply
•Operang Instrucons
Inspeche unior 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 connental 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). Aach the Power connector to the back ohe monitor.
Conneche required cables for video signal input and output. (Power must be applied to the V-LCD171MD for the acve loop-
though outpuo be acvated.) The monitor defaults to ‘ON’ when power is supplied. Video will automacally be detected and
displayed on the screen.

When you are sasfied with the posion, press the SELECT buon or press the BRIGHT knob to confirm your selecon.
The new cropped selecon will be displayed on the screen. If your Aspect Rao is seo AUTO, the monitor will select
the closest aspect rao to the dimensions of your customized Input.
Aspect Ratio
Use this menu opon to switch between several aspect rao sengs.
•In 4:3 mode, images are scaled up or down to fill the maximum 4:3 poron ohe screen.
•In 16:9 mode, images are scaled to fill the enre 16:9 screen.
•In Full Screen, images are scaled to fill the enre screen.
•In Custom mode, images scaling is adjusted to your selecon in the Adjust poron ohe menu:
Adjust
Use any ohe rotary knobs to select your desired aspect rao. Some ohe more common aspect rao
sengs are shown on the Aspect Rao selecon widget. As you move along the scale, your current aspect rao will be
displayed below the widget.

Pixel-to-Pixel
Use this seng to enable Pixel-to-Pixel mode.
This mode bypasses the monitor’s internal scaling funcon and displays images in their nave resoluon and aspect rao, with a
one-to-one mapping ofincoming image pixels to screen pixels:
•For incoming formats smaller than the nave resoluon ohe screen (or selected aspect rao), the image will be
displayed in the center ohe screen using only the necessary LCD pixels. For example, 720p images will occupy exactly 1280x720
pixels in the center ohe screen. The surrounding screen area will be black.
DSLR Preset
Use the DSLR Preset opon to reduce the visibility of on screen indicators shown with popular DSLR cameras. The available
opons are :
•NK 16:9
•NK 3:2
•CN 16:9

Temperature
Use this seng to choose one ohree 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
Selechis 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 ohe screen. The purpose is to allow color matching to
other types of monitors and/or displays. Note: The Color Temperature preset will automacally switch to Custom when Color
Bias sengs are adjusted. Is normal for color bias adjustments to be very subtle.
When selecng the RGB Bias and Gain submenu, bias adjustmenndicators will appear ahe top ohe screen, and gain
adjustmenndicators will appear ahe boom ohe screen:

Use the and buons to select each individual bias or gain control. Highlighng the BIAS or GAIN icons enables a group
change ohe Red, Green and Blue color components, respecvely. Alternavely, you can use the BRIGHT knob to scroll through
the different color components and sengs.
Aer selecng the color componeno adjust, use the and buons to increase or decrease the value.
Gamma
Use the Gamma seng to adjushe value ohe gamma applied to incoming video signals. The default gamma value is 2.2.
Gamma correcon represents the relaonship 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.

Filters Submenu
Use the Filters Submenu to enable various modes.
Check Field
Use the check field modes for monitor calibraon 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 calibrang 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 paern (super black, black, and gray bars) ahe lower-right corner ohe screen. Adjushe
Brightness knob unl there is no visible difference between the super black and black bars, buhe gray bar is sll
visible.
5. Adjushe Contrast knob unl an even grayscale appears along the top bars.
6. Disable Monochrome mode.

7. Enable Blue Check Field modeand adjushe Color knob so thahe 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 seng of camera exposure. As the camera Iris is adjusted, elements ohe
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 ulize this feature, you must understand the color chart below
and have a basic understanding of camera exposure. Normally, when shoong subjects like people, is common pracce to
set exposure offaces 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 addion, 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 ohe image that are approximately 45 IRE. This represents a
‘neutral’ or ‘mid-level’ exposure commonly used for objects (not people).

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 adjushe Threshold and Color by accessing the Adjusuncon. Use the BRIGHT knob
to adjushe Threshold. Adjusng the Threshold toahigher value forces the Peaking algorithm to react quicker to objects
that are in focus. Use COLOR knob to adjushe Color. Your choice is are Red (default), Yellow, Pink, Green and Blue.
Clip
The Clip funcon is used to visually filter data on the screen thasunder a Lower Threshold or over an Upper Threshold.
Data on either side ohe filters can be filtered with a custom color.
The Lower Threshold numerical value and color can be adjusted using the BRIGHT and COLOR knob, respecvely.
The Upper Threshold can be adjusted using the CONTRAST and USER knob, respecvely.

19
In the image above, the Lower Threshold has been seo 20 IRE (Red). This means that any part ohe image UNDER 20 IRE
will be “colored” in RED. Also, the Upper Threshold has been seo 90 IRE (Yellow). This means that any part ohe image
OVER 90 IRE will be “colored” in YELLOW.
Invert
The Clip funcon 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 seo 20 IRE and the Upper Threshold is seo 90 IRE. The Clip Invert will
filter all data in between 20 IRE and 90 IRE and color it RED.
Monochrome
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 ourom 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 ourom regular color video.
