Input Modes and Output Limits
In four-input HDMI 1.3 mode, all four input connectors are available; common resolutions include 1920 × 1080 at 60 Hz. In two-input HDMI 1.4 mode, only the two HDMI 1.4 connectors are available, with common resolutions including 3840 × 2160 at 30 Hz and 3840 × 1080 at 60 Hz. The two HDMI 1.3 input connectors are unavailable in this mode. Interlaced input is not supported.
The PDF’s detailed output section specifies nine HDMI 1.3 outputs, with separate custom width and height limits of 2560 pixels. Its introductory reference to “4K inputs and outputs” should not be read as a 4K 60 Hz rating for each output. Match the intended signal timing to the detailed input and output tables.
Screen Layouts, Presets and Web Control
Output mosaic uses frame synchronization across connectors. Each screen can have its own resolution, and LCD bezel compensation is supported. Layers can cross output connectors without reducing the available layer count. Source cropping, grouped inputs, channel logos and screen-level OSD help organize information on the wall.
Save layouts as presets and create scheduled playlists. The specification lists fade effects and preset switching under 60 ms. Browser control supports multiple users, firmware updates, self-test and hardware monitoring for fan speed, temperature, voltage and operating status.
Use the control card’s Ethernet port for the network connection. Its RS232 COM port is for central control and must not be connected to a router, switch or LED receiving card. The USB 2.0 connector is reserved and does not provide power to connected devices.
