VP-790 - Overview
The VP-790 is housed in a 19” 1U rack mountable enclosure, with rack “ears”
included and is fed from a 100-240 VAC universal switching power supply.
3.1 Using the IR Transmitter
You can use the IR transmitter to control the machine via the built-in IR receiver on
the front panel or, instead, via an optional external IR receiver (Model: C-A35M/IRR-
50). The external IR receiver can be located up to 15 meters away from the
machine. This distance can be extended to up to 60 meters when used with three
extension cables (Model: C-A35M/A35F-50).
Before using the external IR receiver, be sure to arrange for your Kramer dealer to
insert the internal IR connection cable (P/N: 505-70434010-S) with the 3.5mm
connector that fits into the REMOTE IR opening on the rear panel. Connect the
external IR receiver to the REMOTE IR 3.5mm connector.

Aspect Ratio
Set the aspect ratio to: Standard, Full Screen, Crop or Anamorphic (also see
Section 6.3.1):
Standard: Maintains the aspect ratio of the input and scales the image to fit
the display size. The background remains black
Full Screen: Fits the image to the size of the display without maintaining the
aspect ratio
Crop: Maintains the aspect ratio of the input and crops the image so it fits the
display
Anamorphic: scales the input image to 16:9 and fits the 16:9 scaled image to
the display
Note that some aspect ratios may not be applicable to all signal types, in
which case selecting a non-applicable aspect ratio conversion will have no
effect on the displayed image. For example, when a 16:9 image is displayed
on a 16:9 panel all settings give an identical full screen image

Gamma
Set the output gamma: 1.0 to 2.2
Output gamma allows to re-gamma video signals with pre-configured gamma

6.3.1 The Flicker Filter
The Flicker Filter reduces interlace horizontal line edge bounce or flicker when scan
converting from a computer progressive input format to an interlaced output signal.
By choosing the filter strength and recursion mode it is possible to choose between
higher levels of flicker reduction or better motion reproduction.
The flicker filter applies to the DVI and HDMI computer input ports. It does not apply
to the composite, s-Video, component and 3G-SDI video inputs or to interlaced
modes on DVI and HDMI. The filter strength slider is always available and the
strength can be changed but it has no effect to a currently displayed interlace mode
or video input port.

VP-790 - Configuring the VP-790 via the OSD MENU Screens
STANDARD – This setting re-sizes the video or graphics
input signal to best fit the output resolution while
maintaining the aspect ratio of the input signal. For
example, a composite video signal (4:3 aspect ratio) will
“best fit” to the top and bottom of a widescreen output
image, resulting in black areas on either side or top and
bottom edges.
FULL SCREEN – The aspect ratio and resolution of
the input signal is re-sized to precisely fit the size of
the display. This may result in some distortion to the
input signal images
CROP – The aspect ratio and resolution of the input
video or graphics signal are both preserved.
ANAMORPHIC – scales the input image so that it is
displayed with a 16:9 aspect ratio when on the
screen.
The Flicker Filter reduces interlace horizontal line edge bounce or flicker when scan
converting from a computer progressive input format to an interlaced output signal.
By choosing the filter strength and recursion mode it is possible to choose between
higher levels of flicker reduction or better motion reproduction.
6.3.2 Selecting the Correct Aspect Ratio
You can configure the aspect ratio of any output image to fit your application. The
VP-790 offers six different aspect ratio settings: Best Fit, Letterbox, Follow Output,
Virtual Wide, Follow Input, and Custom. Here is how each of these settings works.

For example, you can show a live video window on top of a graphic background, or
a graphic picture side by side with a video window.
The PIP window mode appears in the following preset PiP configurations:
The PIP window size feature lets you select one of three preset sizes or customize
the PIP window to any size.
If the HDMI signal is HDCP protected, it can appear on HDMI and digital outputs that
support HDCP compliant displays. However, it cannot appear on a display that is not
HDCP compliant and the VP-790 will not output a picture on the VGA and SDI
outputs.

PIP functionality is not supported in the Multi-unit operation mode
due to the higher bandwidth requirements of the video processing.
When using multiple VP-790 units to drive a matrix display, it is
essential that all VP-790 units are frame locked, otherwise motion
tear will be observed at the boundaries of the image processed by
each VP-790. The processing mode should be identical for all the
units as well (see Section 6.7).

6.4.1.1 Activating the PIP
You can the PIP feature (indicated by an illuminated PIP front panel button) in any
of the following ways:
Press and hold (for about 2 seconds) the front panel PIP button
Press the PIP button on the IR remote control transmitter (see Section 7.4)
Access the OSD menu, select SETUP>Operation Mode>PIP/Single Mode
and then in the PIP menu select the PIP type
Via the Web pages (see Section 7.3.3)
6.4.1.2 Selecting the PIP Source
To select a PiP source you have to set the VP-790 to any of the PiP display mode
configurations. From the PIP menu, select the PIP source.
6.5 The Multi-unit Screen
Multiple screens can be set in a matrix to provide a larger display that provides a
resolution that is higher than that of a single display. Each display is controlled by
one VP-790 unit. Each VP-790 unit gets the same graphics or video input signal via
a distribution amplifier and outputs the part of the image to its corresponding
display (defined in the Multi-unit OSD screen). In the matrix display the individual
projections usually overlap to give a uniform intersection. The overlapping regions
are illuminated by multiple projectors and are brighter than non-overlapping
regions. For a uniform brightness over the total display, the brightness in the
overlapping regions has to be reduced electronically.

The unit will cut and resize the output signal according to the display’s
location in the matrix
V-Position
Define the vertical position of the display in the matrix
The unit will cut and resize the output signal according to the display’s
location in the matrix
Blend Width
Set the overlap region for the left, right, top and bottom blend regions
In the overlap region, the image intensity gradually fades towards the
edge of the blend area (the fading curve can be controlled via the SCurve item below)
The blend width is set in output pixels with a range of up to a quarter of
the output resolution.
For a configuration with two projectors, for example, in the horizontal
direction, the overlap can be higher to allow 16:9 images to fit on two
combined projectors with an aspect ratio of 4:3 or 5:4
Set the blend width offset for the left, right, top and bottom blend regions
The area between the edge and the start of the blend area is black. The
total number of pixels of the blend area and the offset region is limited by
the same amount of pixels as for an offset of zero

Setting
Function
Blend Width
(Contd.)
Each display in the matrix needs to be set to the same blend
width and offset value for its left and right sides. The top and
bottom blend width and offset values also need to be identical
(though they don’t have to be identical to the left and right
settings). This is necessary for the calculating the Auto Zoom
for the matrix.
Blend Curve Type
Select the blend curve type to Off, S-Curve or Align Pattern
Off: the blend area is displayed without applying any gain factor (align
pattern or S-curve)
Align Pattern: Reduce the image intensity of each pixel in the blend
area by 50%
S-Curve: Select S-Curve when the blend region (defined in the Blend
Width menu item above) and the physical blend match. The S-Curve
reduces the image intensity along the blend width.
Use the S-Curve Value slider to control the image intensity change rate
along the blend area. Use the Output Gamma slider to set the output
gamma to match the gray scale of the images
Black Level Uplift
Set the uplift black level: Non Blend Region, Top Left, Top Middle, Top
Right, Middle Left, Middle Right, Bottom Left, Bottom Middle and Bottom
Right
Setting the black levels for the display edges compensate for additional
light leakage from multiple projectors in the overlapping areas.
The adjustable areas are available according to the position of the
display in the matrix.
Setting the middle regions automatically sets the adjacent left and right
regions, but you can still set the left and right separately.
Reduce Black Level
Uplift Width
Adjust the black level uplift width in case the projection is performed
under non-rectangular conditions.
The black level uplift may be used for bright projectors in dark
environments.
The Black Level Uplift field may need to be adjusted to achieve a perfect
result. There may be an area of light leakage beyond the edge of the
active image from the projector. With these controls the edges of the
black uplift region can be moved so they can be aligned with the edges
of the area of light leakage. In the case of projection under nonrectangular conditions the projection fields of adjacent projectors are not
aligned with the blend region.
The corners of the non-blend region can be moved to allow tracking of
the edge of the projection field of adjacent projectors

Setting
Function
Frame Lock
Set the frame lock mode: Off, Source, Genlock or Auto
Off: the output is set to a fixed refresh rate defined by the frame rate setting (in
the Output menu, Section 6.3), which deviates from the input refresh rate,
even if both are nominally at the same rate. This causes occasional frame
dropping or repeat
Source: the output refresh rate follows the input refresh rate if locking is
possible
Genlock: the output refresh rate follows the vertical sync of an external signal
via the GENLOCK BNC connector, if locking is possible
Auto: Default setup
Locking is achieved by modulating the output clock and works if input and
output refresh rate are nominally at the same rate, e.g. when frame rate is set
to 60Hz and the video input is also 60Hz. If e.g. the video input rate is 50 Hz
and the Frame rate is set to 60Hz, the output will enter free run mode. When
Frame Rate is set to Auto, the matching frame rate is chosen.
When I/O lock is set to Auto and a Genlock source is present to the
GENLOCK BNC. If genlocking is not achievable, locking to the video source
frame rate is tried. If that is not possible the output is running in free-run mode.
When operating in the Multi-unit mode, the same frame lock should
be defined in all the units in the matrix.
