3.3 Defining EDID
The TP-121EDID, TP-123EDID, TP-125EDID, and PT-110EDID include:
• EDID Capture - Copies and stores the EDID from a display device
The Extended Display Identification Data (EDID
1
) 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 graphic source 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.
3.4 Recommendations for Achieving the Best Performance
To achieve the best performance:
• Use only good quality connection cables
2
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 transmitters
away from moisture, excessive sunlight and dust
4 Your TP-121EDID XGA / Audio Line Transmitter
The TP-121EDID is an XGA / audio stereo line transmitter. It receives an
XGA signal and an unbalanced stereo analog audio signal and transmits them
over CAT 5 cable to a receiver
3
, converting the unbalanced stereo analog
audio signal to digital audio (S/PDIF) stream before transmitting, thus
preserving the quality of the audio signal.
When the TP-121EDID is connected to a display device and the EDID
CAPTURE button is pressed, the TP-121EDID reads and stores the EDID
(Extended Display Identification Data) from the display device. The display can
be disconnected and later reconnected without rebooting the operating system.
