3 Overview
The Kramer VM-2DH is a DisplayPort to DVI/HDMI converter and distributor for
digital signals that is HDCP (High-Bandwidth Digital Content Protection)1
compatible. Since high-resolution DVI signals are very sensitive to cable quality
and to PCB layout, the VM-2DH uses a uniquely designed PCB which includes all
buffering, conditioning and amplifying circuitry to provide two high-level output
signals.
In particular, the VM-2DH features:
•Support for resolutions up to WUXGA, including all HDTV formats
•A bandwidth of 1.65Gbps
•The DDWG2DVI 1.0 standard
•Support for up to eight embedded audio channels
•Built in re-clocking circuitry that regenerates the DVI/HDMI signal so that
several units may be cascaded
•A non-volatile read and store memory for the EDID (Extended Display
Identification Data) block from one of the outputs, so it can then provide the
EDID information to the DisplayPort source even if the display device is not
connected
•A default EDID for fast and efficient connection of the unit3
•I-EDIDPro™ Kramer Intelligent EDID Processing™—intelligent EDID
handling and processing algorithm that ensures Plug and Play operation for
DVI/HDMI systems
•A DVI-I connector which is compatible with all types of DVI cables
•State-of-the-art line drivers on both outputs to provide a cost-effective
solution for distributing the TMDS4signals used for DVI/HDMI
3.1 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard5protects digital
video and audio signals transmitted over DVI or HDMI™ connections between
two HDCP-enabled devices to prevent 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.
1 Note that Kramer Electronics Limited is an HDCP Licensee, see http://www.digital-cp.com/about_dcp/list
2 Digital Display Working Group (http://www.ddwg.org)
3 The default EDID feature lets you connect the VM-2DH without having to connect a display to the output

3.2 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital1
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality.
In particular, HDMI2:
•Provides a simple3interface between any audio/video source, such as a set-
top box, DVD player, or A/V receiver and video monitor, such as a digital
flat LCD / plasma television (DTV), over a single lengthy4cable
•Supports standard, enhanced, high-definition video, and multi-channel
digital audio5on a single cable
•Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
•Benefits consumers by providing superior, uncompressed digital video
quality via a single cable6, and user-friendly connector
•Is backward-compatible with DVI (Digital Visual Interface)
•Supports two-way CEC communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
HDMI has the capacity to support:
Existing high-definition video formats (720p, 1080i and 1080p, 2K and 4K) as well
as standard definition formats such as NTSC or PAL
3.3 Defining the EDID
The EDID7is a data-structure provided by a display that describes its capabilities
to the source. The EDID enables the VM-2DH 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.
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-to-analog
conversions
2 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI licensing LLC
3 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables currently
used in A/V systems is reduced
4 HDMI technology has been designed to use standard copper cable construction at up to 15 m (49ft)
5 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to support
Dolby 5.1 audio and high-resolution audio formats
6 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-
effective manner
7 Defined by a standard published by the Video Electronics Standards Association (VESA)

3.4 Recommendations for Best Performance
Achieving the best performance means:
•Connecting only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
•Avoiding interference from neighboring electrical appliances and
positioning your VM-2DH away from moisture, excessive sunlight and dust

5 Connecting the VM-2DH DisplayPort to DVI/HDMI Converter
Figure 3: Connecting the VM-2DH DisplayPort to DVI/HDMI Converter
To connect the VM-2DH as illustrated in the example in Figure 3:
1. Connect a computer graphics DisplayPort source to the DP IN connector.
2. Connect the DVI OUT connector to the DVI projector.
3. Connect the HDMI OUT connector to the plasma display1.
4. Connect the supplied 5V DC power adapter to the VM-2DH and to the mains
electricity.
5. Optional—Acquire the EDID (see Section 5.1).
5.1 Acquiring the EDID
Initially2the VM-2DH operates with the factory default EDID3stored in the non-
volatile memory. The source reads the EDID from the device when the device is
plugged in or powered on.
1 You do not have to connect both outputs
2 This is usually done only once when the unit is being set up in an installation. Once acquired, the EDID is saved in non-volatile
memory and further acquisition is not necessary
3 The VM-2DH reads the EDID, which is stored in the non-volatile memory

The VM-2DH provides the ability to acquire the EDID from:
•One output (the relevant output LED lights)
•Two connected outputs in Auto-Mix mode1(both output LEDs are lit)
•The initial, default EDID (both output LEDs blink)
Pressing the EDID button briefly causes the output LEDs to indicate the source of
the EDID that was last acquired. If the:
•HDMI OUT LED lights, the HDMI OUT EDID was stored
•DVI OUT LED lights, the DVI OUT EDID was stored
•Both OUT LEDs light, the Auto-Mix1EDID was stored
•Both OUT LEDs blink, the default EDID is stored
To acquire the EDID:
1. Connect the power.
2. Connect the output(s) from which you want to acquire the EDID.
3. Press and hold the EDID button to select the desired EDID source.
The OUTPUT LEDs light in the following cycle:
HDMI OUT
DVI OUT
Both LEDS (Auto-Mix)
Both LEDs blink (default)
4. Release the button when reaching the desired EDID source2.
The EDID is acquired.
1 The EDID acquired is a weighted average of all the connected outputs. For example, if several displays with different resolutions are
connected to the outputs, the acquired EDID supports all the resolutions, as well as other parameters included in the EDID
2 If you set the machine to acquire the EDID from an output that is not connected, the default EDID is acquired
