1.Read video ID through the 861 specification,When the input signal is 720p60. The read video ID is 0,

   

0x6f[0] = 1    cable: 

0x6a[4] = 1   hdmi clock:

0x04[1] = 1  pll lock:                        

0x05[7] = 1 HDMI

0x05[6] = 1 not HDCP encrypted

 0x07[5] = 1

 

2 ,When the input signal is 1920x1080p 60,

0x6f[0] = 1    cable: 

0x6a[4] = 1   hdmi clock: 

0x04[1] = 1  pll lock:                             

0x05[7] = 1 DVI

0x05[6] = 1 not HDCP encrypted

 0x07[5] = 0 

In this case, I think the forum said it was caused by EDID, and the final test found nothing to do with EDID.
