7. Marker Config
Selecting a Video Source
Press one of the input direct access buttons (just to the right of the Power button) or…..
Press the INPUT button and then use UP/DOWN arrows or turn the Adjust Knob to highlight
the desired source, then press INPUT or the Adjust Knob to complete the selection.
Press and hold the INPUT button for 5 seconds to see current monitor status.
Note: 4K / UHD may be input several ways:
Single cable 12G SDI to either SDI-1 or SDI-2.
Single cable HDMI to HDMI input, must conform to HDMI 2.0 spec.
Four cable in either Quad or 2SI formats to SDI- 1, 2, 3 & 4.
Two cable Dual 6G not supported.
Also, the monitor can accept four different sources, “Quad Viewer” style. Used this way, all
sources must be synchronous, 1080p and same frame rate.
The Marker Config item allows selection of on-screen markers for Aspect Ratio, Center Mark as
well as “safe action” and “safe area” type borders.
Aspect
Preset marker borders are available for these aspect ratios: Custom, 16:9, 4:3, 14:9, 13:9, 1.85:1,
2.35:1, 1:85/4:3. When Custom is selected, scroll down to Custom Width and Custom Height to
create the desired marker.
Area
The Area setting creates a dotted-line marker showing picture area reductions by percentage:
• 16:9 format choices: 95, 93, 90, 88, 85, 80% (set as desired for safe action/safe title)
• 4:3 format choices: 95, 93, 90, 88, 85, 80% (set as desired for safe action/safe title)
• EBU Action choices: 16:9, 14:9, 4:3 (EBU recommendations for safe action)
• EBU Graphic choices: 16:9, 14:9, 4:3 (EBU recommendations for safe title)
Center Marker
Turns on a “+” Marker in center of screen.
Aspect L. Color
Selects color for Aspect marker (solid border). Choices are: WHITE, YELLOW, BLUE, RED,
BLACK.
Area L. Color
Selects color for Area marker (dotted line border). Choices are: WHITE, YELLOW, BLUE, RED, BLACK.
Line Width
Provides adjustment of the marker line thickness. Range is 0 - 10.
Custom Width and Custom Height
These setting options appear when Aspect has been set to Custom.

V-R241-4K Manual
www.marshall-usa.com910
8. Video Config
The Video Config setting provides control of a wide range of display functions and picture
adjustments.
Aspect Ratio
The Aspect Ratio setting changes the way the width and height of the image is displayed on
the monitor
Choices are: Full screen (the image is presented using all pixels in the display).
Or preset aspect ratios of: 16:9, 4:3, 14:9, 13:9, 1.85:1, 2.35:1, Pixel.
“Pixel” means “Pixel-to-Pixel” mode where each pixel in the source image is mapped 1:1 to
a pixel on the screen. The is the same as “no scaling”. In this mode, a 1920 x 1080 image, for
example, will not fill the screen but will instead fill only the 1920 x 1080 pixel area in the middle
of the screen. A 720p image will be smaller still.
IMPORTANT NOTE: Aspect ratio choices are stored for each input format, they are not global.
For example, setting the Aspect ratio to 4:3 while a 720p source is being displayed will affect
only 720p sources.
Gamma Select
This setting selects the way the monitor will reproduce contrast “gray scale”.
Adjustment is continuously variable from 0.80 to 3.00 in steps of 0.10. From 2.30 to 2.40 the
steps are 0.05.
Common choices are 2.2 (reciprocal of camera gamma setting of 0.45) or 2.4 (mimics gamma of
average color CRT which may be useful when viewing material originally color balance to CRT
reference).
Color Only
This allows setting the monitor to Mono (black and white mode) or Blue Only to provide a quick
check of Color and Tint settings when using standard color bars as a source.
HV Delay (SDI Only)
The video image can be shifted on the display horizontally (to the right), vertically (shifted
down) or both (sometimes called “pulse cross” mode). This allows inspection of the Horizontal
Ancillary Data (HANC) and Vertical Ancillary Data (VANC) spaces. Additional data such as audio,
timecode, closed captioning, AFD and other information is embedded in these blank areas and
transported along with the video.
Choices available are: Off (no shift), H(shift right), V(shift down), H+V (both).
NOTE: Despite the names, VANC appears on screen as the horizontal strip at the top of the
image and HANC appears as the vertical bar to the right of the image.
Peaking Filter
The Peaking Filter function adds color to the sharpest details in the video image. This is intended
as an aid in adjusting best focus in video cameras. Choices are:
Peaking Filter On/Off – Switch this function ON or OFF.
Peaking Color – Select the color that is overlayed on picture details. Select Red, Blue, White,
or Violet.
Peaking Level – Adjust the amount of color that appears on the image detail. Range is 0 to 100.
False Color
The False Color function adds color to regions in the video image based on Luma level. This is
intended as a quick way to compare portions of an image or to warn if levels from a video source
are too high or too low. A colored strip to the right of the image shows the level that each color
represents.
NOTE: As an alternative, the Waveform Monitor function serves the same level measurement
purpose with more precision but without identifying specific regions of an image.
HDR Mode
The HDR Mode supports modern High Dynamic Range technology which allows extended
contrast, color saturation, and gamut. Choices are:
ST 2084-300 / ST 2084-1000 / ST 2084-10000 “Perceptual Quantizer” function to reproduce
PQ HDR video mastered for 300, 1000, or 10,000 Nit displays.
HLG “Hybrid Log Gamma” combines standard Gamma with extended white and specular levels
for HLG mastered HDR video.
HDR Demo ON / OFF (Enhances color of Standard Dynamic Range image to simulate HDR).

V-R241-4K Manual

9. Color Config
Back Light
This setting allows adjustment of the backlight of the LCD panel. This is typically set based upon
ambient room lighting and/or as part of a monitor calibration. Range is: 0 – 100. Default is: 50
Brightness, Contrast, Color, Tint and Sharpness
Adjust the values of Brightness, Contrast, Color, Tint and Sharpness directly from 0 to 100.
Default is: 50
Contrast, Brightness, Sharpness, Color – allow calibration of monitor to normal viewing
standards.
Tint – Tint can be adjusted for any input but the primary purpose is to correct subcarrier phase
errors created from Composite video sources (NTSC / PAL). Tint adjustment is not recommended
for digital sources as they do not possess subcarrier. The exception is when a source has been
converted from composite video and errors remain.
Sharpness – Enhances edges of image detail. To be used sparingly……
NOTE – SHORT CUT: This group of adjustments is available for quick access through the front
panel Adjust Knob. Press the Adjust Knob until the desired parameter shows up, then turn the
knob to make the adjustment.
Color Temp
Select one of the preset Color Temperature choices or make manual adjustment of RGB Gain
and Offset values.
Choices are:
Standard Presets of: 9300K, 6500K, 5400K, 3200K.
Special purpose LUTS: D65 (6504K), C (6674K), D-Cinema (6302K).
USER (See Manual Color Balance below).
VAR (Select from 3200K to 9300K in 100K steps) The most common selection for video work
is 6500K.
Common settings used for other applications are: 9300K, 5400K, 3200K.
Color Space (Color Gamut)
Color Space presets are provided to allow best reproduction of material acquired or color
corrected for a particular color gamut. Choices are: Native / BT 709 (REC 709) / SMPTE-C /
EBU / NTSC / D-Cinema.
Native is the maximum uncalibrated gamut of the display.
Manual color balance settings (User)
Selecting USER for Color Temp allows manual calibration of white and black balance. The
adjustments consist of Red, Green, Blue GAIN and OFFSET. GAIN adjusts the overall level
(amplitude) of a single primary color. OFFSET adjusts the brightness (pedestal/offset) of that
color.
In practice, one of the above Color Temp presets is first selected (rather than USER), then Red
and Blue GAINS are adjusted to achieve a particular white balance (color temperature). Finally,
OFFSETS will need to be adjusted to create a neutral black color. It is normal to have to repeat
these steps until the desired effect is achieved.
NOTE: Adjusting all three colors in the same direction will result in a brighter or darker picture
with no color change, this is self-defeating. Adjustment range is: 0 – 255. Default for GAIN is
200, OFFSET is 128.
10. Audio Config
SDI Gr & SDI Ch (SDI sources only)
SDI inputs can carry up to 16 channels or 8 stereo pairs of digital audio embedded along with
the video.
The 16 audio channels are divided into 4 Groups of 4 Channels each.
SDI Gr provides selection of the desired audio Group for monitoring.
Choices are: Group 1 through 4
SDI Ch provides selection of the individual audio channels for monitoring.

V-R241-4K Manual
www.marshall-usa.com13 14
Choose from Channel 1 through Channel 16 or select OFF (silence). Channels may be monitors
individually or in pairs, 1&2, 3&4, etc.
NOTE: Short-cut. Program one of the User Buttons (F1 – F5) to “Audio Channel” for quick
selection of audio channels without opening the menu system. Seee Control Config section
below.
Level Meter Enable
Turning this function ON causes audio level meter “bars” to appear superimposed over the
picture.
Level meters are only available when monitoring SDI 1 or SDI 2 inputs or HDMI.
Level meters do not appear while the Menu is displayed on screen.
Type (SDI sources only)
Select the number of audio meter bars to be displayed.
Pair shows just a pair of audio meter bars typically representing Left and Right audio channels.
Group shows all four channels from a particular Group.
Level Meter Position
Select one of four meter display positions
Scale Meter Scale
Provides selection of the desired audio meter scale and response mode.
Choices are: Digital (PPM), Nordic, BBC, EBU, DIN, Expanded DIN, SMPTE VU, EBU VU,
France VU
The most common setting is Digital.
Volume
Adjust the speaker or headphone Volume level here.
NOTE – SHORT CUT: This adjustment is available through the front panel Adjust knob. Press
the Adjust knob then turn the knob to make Volume adjustment.
The V-R241-4K monitor comes with several powerful on-screen display (OSD) features.
These include:
• Audio Meter Bars
• Waveform Monitor / Vectorscope display
• Closed Caption decode and text display
• Timecode decode and display
• IMD In Monitor Display of Tally and Text
Most of these may be used at the same time but there are limitations. Some will require position
adjustment to avoid overlap. Others use the same resources and cannot appear on-screen at
the same time.
These combinations may appear on-screen together:
• Timecode, Audio Bars, Waveform / Vector
• Timecode, Audio Bars, IMD
• Timecode, Audio Bars, Closed Caption
These items will conflict:
• Waveform / Vector and Closed Caption
• Waveform / Vector and IMD
• Closed Caption and IMD
Note: A useful trick is to assign Waveform to one of the Function buttons (F1 – F5). Waveform /
Vector can be popped up when needed, interrupting IMD or Closed captioning only as long as
necessary. They will reappear when the Waveform Function button is pressed again.
11. On-Screen Features

G, B, R Display one color primary signal
G+B+R (Displays all three primaries in “parade view”, side-by-side)
Line
When this function is ON, the Waveform and Vectorscope will measure and display a single
line from the video input. The single line that is being displayed on the Waveform Monitor and
Vectorscope is highlighted in the picture as a white horizontal line. As the line number is changed,
this highlight will move up or down the screen. This can be useful during troubleshooting or
when it is desired to evaluate a particular area of an image.
Line Number select: Select video line to be displayed by the Waveform Monitor and Vectorscope.
Line display: OFF/ON/5 Sec Select how long the highlight indicator will remain on the picture
display.
NOTE: The best way to use this feature is to set Line Display to ON, then exit out of the Menu.
Use the Adjust Knob to move the white marker line up or down to select the exact line to be
measured. The line number appears on the Waveform monitor display.
The V-R241-4K monitor can decode and display a variety of Closed Captioning that may be
embedded in the video signal from the selected SDI input. NOTE: Closed captioning is never
embedded in HDMI signals.
It is possible for more than one type of captioning to be embedded in the same digital stream.
Unlike analog Closed Captioning that is found on “Line 21”, digital captioning is not bound to
a particular video line but, instead, is carried in the Ancillary Data space in the SDI stream.
Captioning that is not properly identified or does not conform to standards will not be decoded
and displayed by the monitor.
Caption
This selection turns caption decoding on and selects the type of captioning to decode.
Choices are: 608 Transcoded (original style that has been converted to 708 style)

Choices are: 0%, 25%, 50%, 75%, 100%
DVITC Line
Vertical Interval timecode may be embedded in any line in the SDI VANC (Vertical Ancillary Data)
space. There may be, in some cases, more than one VITC code embedded. The line location of
the VITC code may be selected here. Choices are:
• Auto The monitor will decode the first copy (lowest line number).
• Line 1 ~ 31 (manually select the line number to be decoded).
15. IMD Config
IMD stands for “In Monitor Display” and consists of
large font text which can represent a source name,
a person’s name, or other arbitrary text. In this
monitor, IMD text may be input manually by the user
or electronically from an IMD/UMD controller such as
those from Image Video® or TSL®.
Manual Text Input Method

17. System Config
GPI Control & GPI#
GPI (General Purpose Interface) is the simplest type
of remote interface requiring only a button or switch
connected from one of the control pins on the GPI
connector to the Ground or Common pin. This type of
interface is sometimes called a “pull down”, or “contact
closure” interface. It is compatible with relay and “open
collector” outputs, for example from video production
switchers. Pins 1 - 6 on the GPI connector can each be
assigned to different functions. Pin 8 is the “ground” or
“common” pin.
NOTE: Pin 7 when triggered, operates the same as the front Power button. It will cycle the
power between Operate and Standby modes. Pin 7 cannot be assigned for other functions.
Functions that can be assigned to GPI triggers:
Tally R, Tally G: Turn Red or Green tally LED on. Turn both on for Amber tally (use two GPI’s for
Amber).
Marker On/Off: Toggle Aspect & Area markers on/off, does not change marker settings.
F1, F2, F3, F4 or F5: Same effect as pressing on the front panel button F1 through F5.
Aspect: Cycles through aspect ratio options. “Not available” will appear when video is not
connected.
Aspect Marker: Cycles through aspect ratio Marker options.
Area Marker: Cycles through Area Marker options.
Center Marker: Toggle Center “+” marker on/off.
Input SDI1, Input SDI2, Input Quad, Input 2SI, Input HDMI: Has same effect as pressing
these front panel buttons.
Menu Key, Enter Key, Up Key, Down Key, Left Key, Right Key: Has same effect as pressing
these front panel buttons.
H/V Delay: Cycles through four choices of OFF (no shift), H (Shift image left), V (Shift Image
down), H+V (both shifts).

The fan turns OFF when the temperature drops by the amount shown as Hysteresis (1 – 10
degrees).
The monitor POWER will turn OFF if the temperature exceeds the amount shown in Shutdown.
ON: The fan runs constantly. Recommended when the ambient temperature is expected to be
high.
OFF: The fan will not run. This is not recommended except for short durations. For example, when
live audio is being recorded and the fan noise would be picked up by a microphone. Prolonged
operation with the fan forced OFF may lead to unwanted color changes in the displayed image
as well as reduced monitor life.
18. Communication Config
The Communication Config section provides settings for
three control interfaces:
LAN - Ethernet Network Port. General purpose control.
Capabilities depend on 3rd party control applications.
Can be used for IMD text, changing inputs and most other
parameters.
Serial - RS-232 Port. Primarily used with monitor
calibration applications.
422 - RS-422/485 Port for IMD and general purpose control. Capabilities depend on 3rd party
applications.
Set I.D (01~254)
Select the ID number for the serial ports. This ID number applies to both RS-232 and RS-
422/485 control connections. ID numbers must be in the range 1 to 254. 0 = OFF Assigning an
ID number is useful when more than one monitor or other device will be controlled on a shared
serial connection. Default ID number = 1.
Serial Baud Rate (RS-232 Port)
Select the Baud rate (data rate) for the RS-232 serial port.
Choices are: 2400, 4800, 9600, 19200, 38400, 57600, 115200 Default = 9600
IP Protocol
Select the protocol type for the Ethernet port. The protocol choice depends on the particular
controlling device.
Choices are:
Remcon (Remote Control).
TSL 5.0 – TSL Tallyman Version 5.0 (IMD Control).
TSL 4.0 – TSL Tallyman Version 4.0 (IMD Control).
NOTE: For IMD Control to operate via the Ethernet port set IMD to ON (see IMD Config section
above).
