ADV7181 as a timing generator only to create a 720P reference

I have a project where I used the ADV7181D to create the H-synk, V-synk and DE control to feed an HDMI transmitter and encode just audio over HDMI.

The Project works but I have only been able to generate timings for a 480i signal.

Unfortunately 480i is not fully supported by all TVs and I want to change it to generate 720P timings.



There is NO VIDEO INVOLVED, I just need to use the ADV7181 to generate timing signals.



I have tried multiple combinations of the PRIM_MODE and VID_STANDARD Registers, but don't seem to get it right.

Can anybody provide some help?



Thank you.
