EDID Tab
EDID tab enables analyzing and saving the EDID read from the connected Sink device.
There are three basic functions:
•
Read the contents of the EDID of the downstream sink over the HDMI link.
•
Load and save EDID data files in the host PC
•
Edit the EDID contents
EDID Files
With
Load…
and
Save as…
a hex EDID file can be read and written from the PC. Please
note that the program does not alter the contents of the EDID file or verify its integrity
during load and save operation.
Note
Four blocks (512 bytes) of EDID code is read. If the device is not supporting all
four blocks, the non-supported area is replaced with zeroes.
Currently the EDID Editor does not support Display ID. Hex EDID files can
however be modified with the HEX Editor or externally generated hex EDID files
that have Display ID content can be loaded and programmed into the hardware.
HEX Editor
When EDID content is either loaded from a file or read from the hardware EDID memory,
it is shown in the
EDID Data
panel on the left hand side of the dialog. EDID contents can
be edited by typing over the existing values. Altered content is highlighted with
RED
.
Please note that Hex Editor itself does not alter the contents of the EDID data or verify its
integrity.
After editing the data can either be saved to an *.ecd file in the PC with
Save as…
or
programmed it to the hardware EDID memory with
Write
