The EDID information is typically read from the display over an I2C link. It is implemented as an I2C memory device. Search for VESA EDID on the internet to find documentation of the data provided in the I2C memory device.

Hi Galfonz,
Yes, you are right that we can read the EDID information through I2C interface. I read address 14h from HDMI Core IP SCDC interface, but all values are 00h.
Also I want to change the mode from DVI to HDMI in Altera HDMI IP core. Is there any way to set this in HDMI IP core.
It will be helpful if you could explain how to switch mode from DVI to HDMI.
Also could you confirm that after extracting the HDMI sink module, EDID memory is initialized to default values (as specified by the EDID spec.) or not?
Thanks & Regards,
Manish
