Overview 

The Kramer 

VM-4HDCP

 is an HDCP (High-Bandwidth Digital Content 

Protection)

1

 compatible 1:4 distribution amplifier for DVI-D (Digital) 

signals

2

In particular, the 

VM-4HDCP

. Since high-resolution DVI signals are very sensitive to cable 

quality

 

and to PCB layout, the 

VM-4HDCP 

uses a uniquely designed PCB 

which includes all buffering, conditioning and amplifying circuitry to 

provide four high-level output signals. 

 

Distributes signals having resolutions up to UXGA, including all 

HDTV formats  

 

Has a bandwidth of 1.65GHz 

 

Supports the DDWG DVI 1.0 standard 

 

Consists of a built-in re-clocking block that re-generates the DVI 

signal, so that several units may be cascaded 

 

Can read and store, in non-volatile memory, the EDID

3

 

Has I-EDIDPro™ Kramer Intelligent EDID Processing™

,

 an 

intelligent EDID handling and processing algorithm that ensures 

Plug and Play operation for DVI systems 

 block from 

one of the outputs, so it can then provide the EDID information to 

the DVI source even if the display device is not connected 

 

Has five DVI-I connectors, which are compatible with all types of 

DVI cables 

 

Is a cost-effective solution for distributing the TMDS signals used 

for DVI, and uses state-of-the-art line drivers on each of the 4 

outputs 

The 

VM-4HDCP 

fits in one vertical space of a standard 19” professional 

rack enclosure (1U).
