•  Supports standard, enhanced, high-definition video, and multi-channel 
digital audio
1
 on 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 cable
2
, 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 
•  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 
3.2  Defining the EDID 
The Extended Display Identification Data (EDID
3
) is a data-structure, 
provided by a display, to describe its capabilities to an HDMI source. The 
EDID enables the VM-24HC 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. 
3.3  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-24HC away from moisture, excessive sunlight and dust 
1 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 
2 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a 
simple, cost-effective manner
