to Send a Data from ADV7511 to Oculus Rift DK2

Hi,

I am working on a Hardware project that uses a Oculus Rift DK2.

My System consists of ADV7611(HDMI Receiver), ADV7511(HDMI Transmitter), FPGA and the Oculus Rift DK2.

  PC(HDMI Out) --> ADV7611 --> FPGA --> ADV7511 --> Oculus Rift(HDMI Input)

Now, My system works well when I use a Monitor(LG 24MP55) instead of the Oculus Rift DK2. But when use the Oculus Rift DK2, The Rift displays no image(LED blinks between yellow/ blue in extended mode).

I think that the Video format of Oculus Rift DK 2 HDMI input is not conformed to standards of CEA-861-D Specification.

SO,

My question>  I want to know that I can adjust a timing of HDMI output Signal(ADV7511-->Oculus Rift, like HS, VS, DE).

Thank for Reading. I'm waiting for anyone help.
