We have a system set up HDMI signal -> ADV7612 and the proble is as follows ,
"Vertical Sync Filter" in the IO Map 0x6a is not locked and we are not able to get the measurement values .
During this the Output video has no problem but the Values of V measurement (0x09、0x0a FIELD HEIGHT) in the HDMI Map are not valid values .
This problem is seen when the input is HDMI . When the input is WUXGA Class DVI then we don't see this issue .
If we set "HDMI Map 0x4c 0x00 "instead of the recommended "HDMI Map 0x4c 0x44"
as in Recommend Settings(ADV7612_RecSettings_1-2_021111.pdf) we at least dont see this issue on 1080p60 and 1080i60 inputs .
Please let me know if you have suggestions with regards to this issue .
With best regards and wishes
