I am facing a problem in ADV7611. When I have connected ADV7611 with my PC which is having HDMI Out in NVidia GE Force 210 the Hot plug Assertion (HPA) is asserted and I am getting the expected result. (i.e: Desktop - 1280*720 @ 60 fps).

With the same PC, HDMI Out port in CPU,the HPA is not asserted. I haven't changed anything in the working Firmware. Also i read the cable detect register and Internal EDID register back. They are detected and Enabled respectively. Also I have tried with Manual HPA Assertion, but the result is same,not working.I have probed the 5V from HDMI Host, is also coming. I

I have also connected ADV7611 with my laptop (HP Pavilion dv6) which is having HDMI Port from Intel(R) HD Graphics 4000. Again the same problem is happening.


Is there any initialization firmware for ADV7611. I need 16 bit YUV mode output for 720p60. Please share it with me.
