date user-to-to check for uphttp://www.kramerelectronics.comGo to
manuals, application programs (where appropriate), and to check if
firmware upgrades are available.
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality and position your Kramer VM-2DP away from
moisture, excessive sunlight and dust
Caution:
No operator serviceable parts inside the unit

3 Overview
The high-quality VM-2DP 1:2 DisplayPort Distributor takes a DisplayPort (DP) input
signal and distributes it to two DisplayPort (DP) outputs. In particular, the VM-2DP
features:
•One DisplayPort (DP) input, two DisplayPort (DP) outputs, two output status
LEDs, an active input status LED, as well as an EDID select button
•Up to 2.7Gbps bandwidth per lane
•A maximum resolution of 2560x1600 pixels and a total maximum bandwidth
of 10.8Gbps over four lanes
•I-EDIDPro™ Kramer Intelligent EDID Processing™, an intelligent EDID
handling and processing algorithm that ensures Plug and Play operation for
DisplayPort systems
•Compliance to HDCP
•High-resolution and rich colors and transports audio and multiple video
streams
•5V DC power
3.1 About DisplayPort
DisplayPort (DP) is a digital display interface standard for the PC industry. It
delivers the highest resolutions and sound quality.
In addition, DisplayPort:
•Provides a simple interface between a PC and a display, projector or TV
•Supports 1 to 4 data pairs ("lanes") at a transfer rate of 1.62Gb or 2.7Gb per
second
•Has a maximum length of 15 meters for video transmission, at a resolution of
1080p/60Hz and 3 meters for full bandwidth transmission
•Video specs include a video path that supports 6 to 16 bits per color channel,
a maximum resolution of 2560x1600 pixels and a total maximum bandwidth
of 10.8Gbps over four lanes
•Is backward-compatible with HDMI, DVI (Digital Visual Interface) and VGA,
via an appropriate adapter

4 VM-2DP - Overview
•Version 1.1 supports HDCP (see section 3.2)
•Supports two-way communication over its auxiliary channel between the
video source (for example, a PC) and the digital display, enabling new
functionality such as automatic configuration and one-button play
•Replaces the interface needed between the PC and an external display, as
well as the low voltage differential signaling (LVDS) interface in notebook
computers, monitors, to connect to LCD panels
3.2 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard developed by Intel
protects digital video and audio signals transmitted over DVI or HDMI connections
between two HDCP-enabled devices to eliminate the reproduction of copyrighted
material. To protect copyright holders (such as movie studios) from having their
programs copied and shared, the HDCP standard provides for the secure and
encrypted transmission of digital signals.
3.3 Defining EDID
The Extended Display Identification Data (EDID) is a data-structure provided by a
display, to describe its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the VM-2DP to “know” what kind of monitor is
connected to the output. The EDID includes the manufacturer’s name, the product
type, the timing data supported by the display, the display size, luminance data and
(for digital displays only) the pixel mapping data.
EDID is defined by a standard published by the Video Electronics Standards
Association (VESA).

Distributor
Always switch OFF the power on each device before connecting it to
your VM-2DP. After connecting your VM-2DP, connect its power and
then switch on the power on each device.
To connect the VM-2DP, as the example in Figure 2 shows, do the following:
1. Connect the DP source (for example, a PC with a DP output) to the INPUT
DP connector.
2. Connect the DP OUT connectors to up to two acceptors, as follows:
DP OUT 1 connector to a display
DP OUT 2 connector to a display
3. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity.

5.1 Acquiring the EDID
Initially, the VM-2DPoperates with the factory default EDID (the VM-2DP reads the
EDID, which is stored in its non-volatile memory). This lets you connect the power
before connecting one of the acceptors or sources.
The EDID is usually acquired once, when the machine is being set up in an
installation. Once acquired, the EDID is saved in non-volatile memory and further
acquisition is not necessary.
You can acquire the EDID from:
•One output (the relevant output blinks)
•The default EDID (both output LEDs blink)
When pressing the EDID SETUP button momentarily, the OUT LEDs indicate which
type of EDID was last acquired. If the:
•OUT 1 LED illuminates, the OUT 1 EDID is stored in the non-volatile memory
•OUT 2 LED illuminates, the OUT 2 EDID is stored in the non-volatile memory
•OUT 1 and OUT 2 LEDs illuminate, the default EDID is stored in the non-
volatile memory
To acquire the EDID, do the following:
1. Connect the power.
2. Connect the output or outputs from which you want to acquire the EDID.
3. Press and hold the EDID SELECT button to select the desired EDID.
The OUT LEDs illuminate in the following cycle: OUT 1, OUT 2 and both
OUT 1 and OUT 2 blink (default).
4. Release the button when reaching the desired set up.
The EDID is now acquired.
If you set the machine to acquire the EDID from an output that is not
connected, the default EDID is acquired.
