Mooncell A704 LED receiving card
The Mooncell A704 uses four standard HUB75E interfaces and supports up to eight groups of parallel RGB data. The original description specifies a maximum loading capacity of 512×256 pixels.
Low-brightness grayscale and HDR
The 18Bit+ function is enabled in software. The listing describes a fourfold grayscale increase to help retain low-gray detail when display brightness is reduced.
HDR10 and HLG are listed with a compatible independent master controller and matching HDR source. HDR operation depends on the complete signal path, so confirm the master controller, source format and receiving-card configuration together.
