Using the EDID Editor tool
The 882 provides an EDID Editor Tool. This tool is useful for creating, modifying, and
saving EDIDs, as well as applying EDIDs to HDMI emulator ports for source testing.
Using the EDID Editor Tool involves the following basic steps:
1. Loading an EDID into the Editor. An EDID is loaded from a file stored on the generator
file system or host PC, or by capturing and loading an EDID from a display connected
to the 882CA HDMI or VGA interface.
2. Modifying EDID settings using the tool’s user-friendly graphical interface. Operations
are accomplished using check boxes, text fields and pull-down list boxes with human
readable field descriptions and value options.
3. Saving a modified EDID to a file stored on the generator file system or host PC, and/or
by putting (writing) the EDID on a display connected to the 882CA HDMI interface
(display must have writable EEPROM).
4. For source testing, applying an EDID to one of the HDMI Rx ports for emulation.
Note: When creating EDIDs for source testing (for computer monitors in the IT market or
TV displays in the CE market), it is important to understand the specifications which define
the structure of the EDID you are creating. The EDID structure is defined by VESA and and
the extensions are defined by the CEA in the 861 specification.
Loading EDIDs
The procedure below provides instructions on loading EDIDs into the EDID Editor Tool.
To load an EDID:
1. Make appropriate cable connection as follows:
• If you are capturing and loading an EDID from an HDMI display, connect an
HDMI-to-HDMI cable between the HDMI OUT connector on the generator and the
HDMI connector on the display under test.
• If you are loading an EDID from one of the HDMI Rx ports on the generator,
connect an HDMI-to-HDMI cable between the HDMI Tx connector on the generator
and the HDMI Rx input ports that is configured with the EDID you wish to load.
• If you are capturing and loading an EDID from a VGA monitor, connect a
VGA-to-VGA cable between the VGA connector on the generator and the VGA
connector on the display under test.
