ADV7842 with 1080p60 when 'No 5V cable detect'

At hardware side, RXA_5v is left open; at software side, DIS_CABLE_DET_RST is set as '1', means 'do not use the 5V input pins as reset signal for the HDMI section'.


When connect with the camera through HDMI interface where No 5V cable detect is the case, 1080p30/720p60 etc. works quite normal, but 1080p60 and 1080p50 flick, then with a pulse of 5V on RXA_5V through a flying wire, 1080p60 and 1080p50 both get normal.


Meanwhile, every mode works fine on the product where ADV7604 is applied in 'No 5V cable detect'.


Could this problem be solved by just changing software but not flying wire? Thanks.
