Although flat panels of a similar type use similar sets of signals from the video controller, they do
not share a standardized interface connector pin configuration. The names of panel control signals
vary from manufacturer to manufacturer. Read the description of each signal carefully to
determine how each signal is used for the display you choose. Refer to the panel manufacturer’s
technical literature to determine how to wire a cable for the panel you choose for your application.
