1Product Overview
The V-R231P-AFHD features our Completely Digital TFT-Megapixel™ system and can display native high definition images on
the LCD/TFT screen with 6.9 million pixels. Analog signals are digitized using an advanced 10 bit process with 4x over sampling
and adaptive 5 line comb filter plus exacting color space conversion. Video is scaled to fit on screen in the highest resolution
using a state of the art LSI that incorporates adaptive 7x7 pixel interpolation and precision Gamma correction to product the best
images available. Additional features include, Pixel-to-Pixel™ native resolution scaling, setup memory, 6 Frame Marker Overlays,
Blue Gun, and direct access for all adjustment and selection functions The V-R231P-AFHD has been designed for field and studio
applications with a rugged, all metal enclosure and optional optical grade screen protection. A VESA 75mm mount is included and
can be used with optional desktop or rack mounted systems.

Video Screen Formats and Frame Rates
9. Overlay Enable
Must be turned on to enable Frame Marker, Center Mark and Safe Area functions.
10. Frame Marker (Only active in 16:9 display mode) (Requires OVL to be enabled)
Frame Aspect Markers appear as RED lines that are used to frame the image for an additional screen format when 16:9 display
is enabled. For example 4:3 marker is often used for HD broadcasts that are also down converted and cropped for SD trans-
mission. Frame markers are available for 4:3, 15:9, 14:9, 13:9, 1.85:1, 2.35:1 and 2.37:1 screen aspects.
11. Center Mark (Requires OVL to be enabled)
A cross hair cursor is placed on the middle of the screen. The lines of the cross hair consist of a center white element that is
4 pixels wide, surrounded by a black border on each side that is 2 pixels wide. Use of black and white for the Center Mark
function allows the viewer to see screen center in all ranges of color for the screen image.
12. Safe Area Overlay (Requires OVL to be enabled)
A shaded border is placed onto the edge of image indicating a user selected area deemed to be safe for graphic and
other image placement. Safe Area overlays are available that indicate 80%, 88%, 90%, and 93% of the displayed im-
age. The safe area displays for the selected screen aspect.
13. Image Adjustment Controls
Use to adjust image appearance on the screen. The tint control will only function for NTSC composite and
S-Video sources and is not available in all other formats. Each knob has a center detent position that approxi-
mates a normal setting calibrated to standard SMPTE color bars.
14. HyperProcess™ Interlace Image Motion Compensation (Disabled for progressive and PC formats)
Holding OSD then tapping TEMP will toggle through 3 selections of interlace motion compensation.
Interlace images such as 1080i and 480i must be converted to progressive images for presentation on the LCD/TFT screen. This is
accomplished via 3 user selected interpolation programs. Default, MC-1 and MC-2.
Interpolations are performed based on motion of individual pixels in 7x7 pixel groupings for luminance and chrominance. Motion is
detected in horizontal, vertical, and diagonal directions.
The default setting uses inter-field interpolation processing to create an image based on field 1 plus field 2 changes and outputs to
the screen 60 or 50 times per second based on input frame rate. Each frame is made up of the current field information plus changes
detected in the transition from the previous field. There is a one frame propagation delay in this mode.
MC-1 – Intra-field interpolation processing is used to transform each field into a single progressive frame based upon information
within the field. There is a single field propagation delay in this mode.
MC-2 – Uses inter-field processing to generate true frame of field one plus field 2 with no motion compensation. Images are presented
via a segmented frame system that creates progressive frames based upon 2 half image samples of odd and even lines much the
same as CRT processing for interlaced images. Motion artifacts will appear as jagged edges in this mode since field one and field
two frames are displayed simultaneously with no compensation for spatial motion during the sample period. MC-2 has a one frame
propagation delay.

8. Blue Gun & Mono (Monochrome Black & White)
Use to adjust SMPTE or split field color bars.
1. Allow monitor to warm up for 15-20 minutes minimum. Adjustments will not be accurate on a cold monitor.
2. Display SMPTE color bars on monitor. Turn on Mono
3. Find the PLUGE (superblack, black, and gray bars) at the lower right of the pattern. Adjust BRIGHT-
NESS control until there is no difference visible between the superblack and black bars, but a difference is
visible between the black and gray bars.
4. Adjust CONTRAST control to achieve a balanced gray scale across top bars.
5.Turn off Mono then turn on BLUE GUN
6. Turn up CHROMA(color level) control until the two outermost bars (white and blue appear to match in brightness.
7. NTSC Only -Adjust COLOR PHASE (tint or hue) control until the third bar from the left (cyan) and
the third bar from the right (magenta) appear to match in brightness.

5Operational Setup
1. Unpack the V-R231P-AFHD and accompanying V-PS24-7.5 power supply. Physically inspect for any 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 [phone].
2. After inspection, install in your desired location. Marshall Electronics offers a desk top stand or rack mount kit for a standard EIA 19-inch
equipment rack. Adequate ventilation is required when installed to prevent possible damage to the V-R231P-AFHD internal components.
3. Connect required cables for signal input and output. Please note that power must be applied to the V-R231P-AFHD for all outputs to be
activated. All BNC connectors should be rated for 75Ω.
4. Attach XLR 4 pin power connection from V-PS24-7.5 power supply to the back of the unit.
5. Plug the V-PS24-7.5 power supply into the A.C. source
6.Turn on the V-R231P-AFHD by depressing the power switch located on the front of the unit.

1. Power On/Off Button with System Reset
Illuminates Red when system power is present. Illuminates Green when monitor is ON.
System reset will also occur with Off/On cycle. Active Outputs require power to be applied.
All input signals appear as output signal. Analog output signals are buffered and amplified.
2. Source Selection Buttons
HDSDI - Digital Input for Standard Definition (SDI-270Mbs) or High Definition (HDSDI-1.43Gbs)
Video - Composite NTSC or PAL. Composite video must comply to SMPTE-RS170A.
Images without color burst (Subcarrier) component may not display.
S-Video - Y/C (Luminance + Chrominance) NTSC or PAL
YPrPb - Analog Component color difference signals for Standard Definition (YCrCb) or High Definition (YPrPb)
VGA/DVI - Toggles between Analog PC or DVI-I connectors.
DVI - Digital or Analog Computer or Video Signals. Includes HDCP and can be used with HDMI originated signals via an adapter cable
3. Under Scan (Not Available for HD and PC Signals)
Displays scaled images without vertical and horizontal blanking applied. This function can only be used with Standard definition
signals. SDI signals will display all data input with ancillary data appearing to the right of the image.
4. Aspect Ratio
Displays scaled images in three screen aspect formats. 4:3 used mainly for Standard definition
16:9 used mainly for HDTV images.15:9 or Fill Mode is indicated by illuminating both LEDs. This mode will fill the entire
display screen regardless of the original screen aspect.
5. Pixel to Pixel Function
As the native LCD display of the V-R231P-AFHD is 1920 pixels wide by 1200 pixels high, it may be necessary to change the
size of the image to fill the screen in the desired aspect. Pixel to Pixel mode bypasses the enlargement/shrink of this scaling
function and displays the native incoming format.
For 525-NTSC/480P based images, pixel to pixel will appear as a 480h x 640w (4:3 aspect) or 480hx720w (16:9 aspect).
For 625-PAL/576P based images, pixel to pixel will appear as a 576h x 640w (4:3 aspect) or 576w x 720h (16:9 aspect).
For 1080 line HD based images, pixel to pixel will appear as 1080h x 1920w (16:9 aspect)
For 720 line HD based images, pixel to pixel will appear as a 720h x 1280w (16:9 aspect)
6. Color Temperature
The V-R231P-AFHD has four color temperature settings that adjust the color balance of the screen for varying ambient conditions.
D-55 (5500K) - Simulates indoor incandescent light conditions.
D-65 (6500K) - Standard setting recommended by SMPTE and EBU. Simulates normal daylight conditions.
D-75 (7500K) - Simulates bright daylight conditions.
