Before configuring the LED screen
Match the DVI source timing, screen dimensions and receiving-card configuration to the controller. The five resolutions above preserve the original page information; the difference between 2048 × 640 and 2048 × 668 should be checked against the supplied device and specification version before a screen layout is finalized.
The USB connection is for control communication, while DVI carries the video source. Plan the audio and light-sensor connections separately using the interface definitions in the specification.
