Legend: Response length is 164 characters. Each number represents the EDID validity
state for the corresponding memory location. The first 50 numbers (bold) are representing
the factory preset EDIDs, the second 50 numbers are representing the User saved EDIDs.
From the next 32 numbers the first 16* (italic) are showing the outputs’ EDID state, and
from the last 32 numbers the first 16* (bold and italic) are showing the emulated EDIDs on
the inputs.
* The number depends on the matrix size. (16, 12 or 9)
If a changed EDID is queried by the {wh} command (see the next section), its value returns
to ‘1’.
Explanation: There is one ‘3’ in the table on the 137
th
position. This means that the
emulated EDID on input 5 is changed since the last EDID query on that port.
