need help to configure edid editor to generated edid register values for 1080p@60 Hz only....
I think it might be worthwhile to ask about an EDID on the FPGA Reference Designs forum.
In the mean time, you could modify the EDID configuration script in the ADV7611 Design Support Files FAQ:
This should allow the computer to recognize the ADV7611 as an HDMI sink. Then you can choose the appropriate resolution on the computer.
Moved to correct forum...
The EDID file in the ADV7611 configuration script is a good place to start. I have attached this data in a format that is compatible with EEDIT.
Also, the following thread has some screen captures of ADV7611 content:
i am using non hdcp version of adv7611 ...
will it support 1080p@60hz from hd7770 graphics card....
which block i need to configure...vesa block or cea block....
I tried to use EEdit tool. I removed all unused resolutions in CEA1 block except1080p@60 and 1080p@60 marking as native the first one. Is there something other to change?
I'm told the software for that board (Avnet FMC Imageon) includes the ability to load an example EDID. Have you experimented with this?
we have used the edid ADV7611_EDID script as you told.And got expected output ..But when we are giving 1080p@60p to adv7611..from graphics card..the register reading shows that the input processed by the CP core is interlaced and also the clk detected is 74MHz ecpected is 148 mHz
Are you absolutely sure that your computer is outputting 1920x1080p @ 60Hz? Some computers only support 720p/1080i output.
Anyway, it looks like the default EDID provided with the FMC-Imageon supports 1920x1080p so you should probably be using that. Folks in FPGA Reference Designs forum know more about that.
yes i am sure ...we r using Graphics card hd7770 in which we can set the output resolution to 1080p 60Hz...
What frequency do you measure on the HDMI clock pin on the connector? That will let us know whether the graphics card is outputting 1080p or not.
We r getting 74 Mhz from the HDMI clk read only register
It sounds like your graphics card is outputting 720p/1080i. But you will need to measure the frequency on clock pin on the HDMI connector in order to confirm this.
I'm not sure what HD7770 graphics card will do with regards to HDCP encryption. I suppose it depends on the software drivers and what the computer is doing.
For example, if the computer is playing a movie or copyrighted content, it will likely enable HDCP encryption. But if the computer is just showing the desktop, then it will likely not enable HDCP encryption.
With regards to the EDID contents, I think the computer will output video as long as the sink has a VESA block. DVI displays typically contain only VESA block.
