3.3 About HDCP
High-Bandwidth Digital Content Protection (HDCP) standard
1
protects digital
video and audio signals transmitted over DisplayPort, HDMI or DVI
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, encrypted transmission of digital signals.
3.4 Defining EDID
The Extended Display Identification Data (EDID
2
) 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-4DH
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.
3.5 Recommendations for Best Performance
To achieve the best performance:
Connect 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)
Avoid interference from neighboring electrical appliances and position
your
VM-4DH
away from moisture, excessive sunlight and dust
