[ Original Effect] [Effect After Connecting the Expansion Dock] The music spectrum flashes once after detecting a beat. Ripple Effect (RGB lights at the bottom of the expansion dock, spreading a wave of random color from the center outwards). AIDA64 secondary screen features random color breathing overload effects (the color at the bottom changes to red faster depending on CPU or GPU usage), a weather clock with random color breathing loading effect, and a game console with random color breathing charging effect (press and hold the B button to charge the left half of the light column, press the A button to charge the right half, and release to release the energy). When connected to the expansion dock, the secondary screen's built-in USB port can connect to a keyboard and a regular HID controller for use as a NES emulator. See the video demonstration for details . This is the user manual; the firmware is constantly updated. A convenient flashing and MJPEG conversion tool has been developed. Many people have already successfully replicated the secondary screen.
