Users Guide
Product Overview
The V-R231P-AFHD features our Completely Digital TFT-Megapixel™ system and can display native high defi nition 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 fi lter plus exacting color space conversion. Video is scaled to fi t 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 fi eld 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.

8. Blue Gun & Mono (Monochrome Black & White)
Use to adjust SMPTE or split fi eld 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 BRIGHTNESS 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.
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 transmission. 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 image. 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 approximates 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-fi eld interpolation processing to create an image based on fi eld 1 plus fi eld 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 fi eld information plus changes
detected in the transition from the previous fi eld. There is a one frame propagation delay in this mode.
MC-1 – Intra-fi eld interpolation processing is used to transform each fi eld into a single progressive frame based upon information
within the fi eld. There is a single fi eld propagation delay in this mode.
MC-2 – Uses inter-fi eld processing to generate true frame of fi eld one plus fi eld 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 fi eld one and fi eld
two frames are displayed simultaneously with no compensation for spatial motion during the sample period. MC-2 has a one frame
propagation delay.
