Screen Configuration and Testing
Data-group exchange and data-group offset settings help configure the screen layout. Smart settings include point drawing and tracing, with support for different screen-unit alignments. The integrated screen test checks brightness uniformity and module flatness.
Use the recommended loading range together with the module-width limits when planning a cabinet. Match the module driver IC and scan mode to the receiver configuration before connecting multiple cards.
