You are correct. Dual link 74.5MHz is valid for 1080P@60Hz.

AV_Mute 9: lvds unlock,==========Set AV Mute============

AV_Mute 9: lvds unlock,==========Set AV Mute============

AV_Mute 9: lvds unlock,==========Set AV Mute============

AV_Mute 9: lvds unlock,==========Set AV Mute============

This fault is caused by two reasons.

  • Poor crystal contact in the LVDS2HD. See the diagram below:
