Pixel-to-Pixel Mode
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, NTSC or PAL images will
occupy exactly 720 x 486 or 720 x 576 pixels respectively. The surrounding screen area will be black.
•
For incoming formats exceeding the screen resolution (or selected aspect ratio), only the center portion of the
incoming image will displayed, with the remainder of the picture cropped. For example, 1080i/p formats will both
be cropped depending on the selected aspect ratio.
■
Aspect Ratio Settings
Use this menu option to switch between several aspect ratio settings
As the V-R231-IMD-HDSDI monitor has a native resolution of 1680 x 1050 RGB pixels, incoming images are
automatically scaled to fit the screen:
•
•
•
•
In 4:3 mode, images are scaled up or down to fill the maximum 4:3 portion of the screen (1600 x 1200). IMD text
and time code are superimposed on the lower portion of the image. The audio presence indicator and on-screen
tally are displayed at the bottom of the screen, outside the image.
In Scaled 4:3 mode, images are scaled to a smaller 4:3 portion of the screen, leaving space for IMD text, tally,
and audio presence indicator to be displayed below or around the image. Time code is superimposed on the
lower portion of the image.
In 16:9 mode, images are scaled to fill the maximum 16:9 portion at the top of the screen (1920 x 1280). In this
mode, IMD text and on-screen tally are displayed below the image. Time code and the audio presence indicator
are superimposed on the lower portion of the image.
In Full Screen (16:10) mode, images are scaled to fill the entire 16:10 screen (1920 x 1200). In this mode, all
OSD features are superimposed on the image. Note that when using a 16:9 input image in this mode, the
image will be slightly vertically stretched.
The diagrams on the following page show how IMD text, timecode, and the audio monitor icon are simultaneously
displayed on the screen in each aspect ratio setting. The white area represents the video image.

Overview
The V-R231-IMD-HDSDI features an In-Monitor Display (IMD) with the ability to display on-screen text and tally in
three colors. IMD text, color, and alignment can be assigned to each screen locally using menu options (see below).
Alternately, IMD text and tally can be remotely controlled via the RS-422/485 serial interface using several industry-
standard protocols, including TSL and Image Video. Multiple V-R231-IMD-HDSDI monitors can be looped together and
each addressed individually via the protocol. All menu features of the V-R231-IMD-HDSDI can also be controlled via
the Marshall Network Controller box and Marshall protocol. (Contact Marshall Electronics for additional information).
Use the IMD Configuration submenu to configure various IMD parameters as described below.
IMD Configuration Submenu
■
IMD Protocol

commands. Currently, four protocols are available. Contact Marshall Electronics for the latest protocol compatibility.
Image Video
Use the Image Video protocol setting when controlling the IMD from an Image Video tally controller (e.g. TSI-
1000) or other controlling device which utilizes the Image Video protocol. The IMD #, IMD Name(S/N), and Baud
Rate parameters must be set for each screen in conjunction with the controlling device.
TSL v4.0
Use the TSL v4.0 protocol setting when controlling the IMD from a TSL tally controller, or other controlling device
which utilizes the TSL v4.0 protocol. The IMD # must be set for each screen in conjunction with the controlling
device.
Marshall
Use the Marshall protocol setting when controlling the V-R231-IMD-HDSDI using the Marshall Network Controller
box. This protocol allows remote control of all features on the V-R231-IMD-HDSDI, including marker setup, video
configuration, system configuration, and image adjustments (brightness, contrast, etc.). The IMD #, IMD Group #,
and Baud Rate parameters must be set in conjunction with the Network Controller Box.
Marshall-IV
This protocol setting accepts Image Video commands via the Marshall protocol, for use when an Image Video
controller is connected to the Marshall Network Controller box.

IMD CONFIGURATION SUBMENU (continued)
■
IMD ID #
The IMD ID # identifies each screen to the controlling device. When using the TSL protocol, the ID # of each screen
should be manually set in conjunction with the controlling device. When using the Image Video protocol, the ID # may
be set automatically by the controlling device, after each IMD is initially identified by IMD Name (see “IMD Name[S/N]”
below). Available ID #s are 000-255. When using the Marshall protocol, available ID #s are 001-254.
■
■
IMD Group #
Each screen can be assigned an IMD Group # when using the Marshall protocol. Available Group #s are 01-254.
IMD Name (S/N)
Use this setting to assign a name to each screen when using the Image Video or Marshall-IV protocols. The IMD name
is equivalent to the Image Video serial number and is used by the Image Video controlling device to identify
each screen. The default IMD Name(S/N) is “M00000.” It is recommended to maintain this naming scheme in order to
avoid serial number conflicts with other Image Video devices on the same serial bus. Each name can be up to 16
ASCII characters.
Press ENTER to edit the IMD Name. Use the ↑ and ↓ buttons to move the cursor. Press ENTER with the cursor on the
character to be changed and use the ↑ and ↓ buttons to scroll through character options. Press ENTER to choose a

Maintenance
■
Screen Cleaning
Periodically clean the screen surface using ammonia-free cleaning wipes (Marshall Part No. V-HWP-K). A clean micro-
fiber cloth can also be used using only non-abrasive and ammonia-free cleaning agents. Do not use paper towels.
Paper towel fibers are coarse and may scratch the surface of the polycarbonate faceplate or leave streaks on the
surface. Antistatic and fingerprint resistant cleaning agents are recommended. Do not apply excessive pressure to the
screen to avoid damaging the LCD.
■
Faceplate Dusting
Dust the unit with a soft, damp cloth or chamois. Dry or abrasive cloths may cause electrostatic charge on the surface,
attracting dust particles. Neutralize static electricity effects by using the recommended cleaning and polishing practice.
