Clicking this control will extract the EDID from device
connected to the output connector and save it in the unit.
The user must confirm the action.
EDID Data Display
The data shown in the EDID table is continually
scanned to ensure that the checksums for each
block is valid.
When wrong checksums are detected, the
invalid checksum byte is highlighted in RED.
If an action is performed that affects the EDID such as initiating a "learn" process,
The checksum field might momentarily flash ‘RED’ during the this process, but
should go back to normal once the entire table is updated.
NOTE
You cannot “LEARN” an EDID that has an invalid checksum. If you try to learn an EDID that has a
checksum error, the HDMI and MUTE Button LEDs on the unit will alternately flash 5 times to
indicate the error.
No other checks are performed on the EDID to determine that it is valid per the EDID standard.
However, the GUI software can import and upload to the VSA-X21, EDID’s that contain invalid
checksum for testing purposes.
