Hello.
In our design we use EDID data, approved for various DVI/HDMI sources. This data (file edid020.dat) is:

 

       EDID BYTES:

This file opened by ADI Advantiv EDID Editor ver 0.20, gives the following:

1. VESA BLOCK.
    Product ID - should be 0220, is available H@B.
The ID Product code field contains a 2-byte vendor assigned product code. This is used to differentiate

between different models from the same manufacturer. If this field is used to represent a model

number, then the number is stored in hex with the least significant byte first (VESA E-EDID Standard,

Release A, Revision 1, page 11).

2. CEA BLOCK.
   2.1. Audio - should be 16 bit and 20 bit, is available 16 bit only.
   2.2. DTDs - in our case there are five DTD, #1. #2, #3, #4 and #5. When the file edid020.dat is

opened, Advantiv EDID Editor shows correct values of all parametres for all DTD. However, if to execute

operation "Check" then values of parametres catastrophically collapse. The table edid_check (see

attachment) shows values of DTD parametres before and after to operation "Check".

 

I ask the help in the decision of these problems.
Alexander.
