Video data can be deemed invalid based on MSA and timing information, for example. The sink may implement the ability to disable the black video function, as described in Note 1above, for system development and debugging purpose. The signal is used to strobe the pixel data and DE signals. All pixel data shall be valid at the falling edge when the DE signal is high. When the signal is high, the pixel data shall be valid to be displayed. Output signals from any system shall be low or High-impedance state when VDD is off.


Input signals shall be low or High-impedance state when VDD is off.
