Model and interface note: this listing is for HD-D36. Earlier page text also named D16/D15 and listed four HUB75E connectors. The linked D36 V0.1 specification instead identifies one 50-pin HUB and provides its pin definition. Confirm the actual board and required module connection when replacing hardware.
Programs and display effects
Create text with inserted pictures, word art, animated backgrounds and neon effects. Clock options include analog, digital and dial displays, with counting functions also listed. Temperature/humidity display and adaptive brightness adjustment are supported features.
The card supports direct video transfer without waiting for transcoding. The specification describes more than four hours of program support with 4 GB memory; actual stored duration depends on program content. USB-drive expansion and plug-in playback provide another way to load programs.
