Why hasn't ADV7619 working script ever mentioned EDID configuration?

I am really surprised ADV7619 as a mature chip from ADI which well-known as a prestigious leader in the electronics world, has organized all its tutorial documents in such a mess!!! So many engineers have to use the forum posts to inquire ADI application engineer with their basic bringing-up. What is worse, as far as I see, numerous of problems are the similar without a perfect answer!

I have gone through quite a few dozens of question posts in the forum. I have been referring to the script of "ADV7619-VER.1.9c.txt", in this tutorial, there is nothing ever mentioned that whether the user need to configure the EDID info or not in any application scenario.  

Only by referring to this similar thread, I know we need to configure it explicitly if we need to use internel EDID. Can you provide an conclusive answer to this thread?

If I want to use the internal EDID, do I have to use this utility to generate an customize an EDID by myself?

  • Hello

    1) An EDID is not required to allow the ADV7619 transfer video. The EDID is just a way for the sink to communicate to the source what formats it can support. From the EDID block shown below, there is no 4K format included. If you are using test equipment you can force a 4K output else commercial sources will only allow what is in the EDID. Copy the following block into a test.dat file and open it with EEditGold to edit the block

    20 From our website the evaluation board only uses a single 24-bit bus output since it only has a ADV7511 as a TMDS transmitter. If you are truly running formats above 170 MHz then you will have to set OP_FORMAT_SEL correctly as listed in Table 12 and use the 48-bit bus.
