Installation and Initial Setup

■Unpacking

Carefully unpack the V-LCD17HR monitor and verify that the following items are included:

• V-LCD17HR Monitor

• V-PS12-5V-1 Power 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 (800) 800-6608.

If you are not located within the continental United States, call +1 (310) 333-0606.

■Installation

The V-LCD17HR can be mounted in any standard EIA 19” equipment rack. The attached rack ears can be angled to provide the user control over the viewing angle. Adequate

ventilation is required when installed to prevent possible damage to the monitor’s internal components. Please see the Dimensions section for more information.

A VESA standard 75mm hole pattern also allows custom mounting installations. Alternately, the V-LCD17HR can be used in a desktop configuration with optional stand.

Please contact Marshall Electronics for more information.

■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-LCD17HR 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.

Top and Front Panel Features

Power Button

Use the power button to toggle between ON and STANDBY modes. In both the

STANDBY and the ON state, the LED on the button will illuminate bright green. This

indicates that MAIN power is applied to the unit.

User-Definable Function Buttons

Two user-definable function buttons can be used for direct access to various

settings. Functions are assigned using the on-screen menu.

Menu Navigation Buttons

Use the Menu, ▲,▼, and Select buttons to display and navigate the on-screen

menu (See Main Menu and Navigation).

Image Adjustment Knobs

Use the image adjustment knobs to adjust color brightness, color-saturation, tint,

and contrast of the image. The status of each image adjustment parameter is shown

on the bottom left of the screen, with values ranging from 0 to 100. Default value is

50.

LED Tally

Three LED tally lights (yellow, red, green) are available above the screen.

Rear Panel Features

Power Input

Connect 12VDC to the 4-pin XLR power input connector. Power should only be

supplied from the included power supply.

IMPORTANT: If using a power source other than the included power supply, damage

may result. Please use the pin out diagram in the Specifications section.

Tally Input Connector

The LED tally can be activated via the HD-15 connector by connecting the

corresponding pin to ground. A variety of external devices can be used to perform

the contact closure. No additional power should be supplied to the HD-15 port.

Desktop Mounting Holes

These holes are used when attaching the monitor to the optional desktop

stand.

VESA 75mm Hole Pattern

VESA-standard 75 mm hole-patterns is provided to accommodate a variety of

custom mounting options. See Dimensions for further details.

Input Connection

The V-MD monitor comes preconfigured with 3G-SDI and a Loop Out or 2xHDSDI

inputs. See the Compatible Input Formats list for compatible formats.

PROG Port

The PROG port is a Service / Upgrade port only. Please contact Marshall Electronics

for more information.

MAIN MENU AND NAVIGATION

Access the main menu by pushing and holding the MENU button on the front panel of the monitor.

•Step through menu items using the ▲and ▼buttons.

•Choose a submenu or select a menu item by pressing SELECT.

•Return to the previous menu by pressing MENU.

•Exit the main menu by pressing MENU. The menu will automatically time out after 15 seconds.

VIDEO CONFIGURATION SUBMENU

■Color Temperature

Use this setting to choose one of three color temperature presets:

• D55 (5500K)

• D65 (6500K)

• 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.

RGB Bias and Gain

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.

• In Full Screen mode, images are scaled to fill the entire screen.

• In 4:3 mode, images are scaled to fill the center 4:3 portion of the screen. 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 , 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:

• For incoming formats smaller than the native resolution of the LCD panel, 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.

MARKER CONFIGURATION SUBMENU

Use the Video Configuration submenu to select various video settings such as monochrome mode or blue-only mode.

■Marker Enable

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

Use this setting to display a center marker on the screen.

■16:9 Markers

Use these settings to superimpose one of 12 markers on the screen when in 16:9 mode.

• 0% The marker is superimposed on the complete image.

• 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).
