Hi,

 

I have a question on ADV7619. If my video source is HDMI, 480i and 576i works fine, HDMI mode is detected, and HDMI_PIXEL_REPETITION is correct, 0001 - x2. But is video source changed to DVI 480i or 576i, HDMI_PIXEL_REPETITION reading is wrong, always 0000, and DVI mode is detected, but randomly read back HDMI mode detected. This also causes output video not stable.

 

Does ADV7619 support DVI 480i(720(1440)x480i 60Hz) or 576i(720(1440)x576i 50Hz)? Any register settings I should do?  

 

Thanks!
