SI-304 is a powerful super-slim digital signage system that simultaneously supports four displays with 4K ultra-high-resolution, as well as four independent audio outputs. It is currently the thinnest TV wall signage system in the market and is an ideal advertising tool for multi-screen TV to communicate sales campaigns and promotions. Its flexible video wall layout settings support TV wall configurations with maximum resolution of 8K by 4K based on a 2 x 2 video wall setup. The system is designed with segregated ventilation to prevent dust and contaminants from disrupting the electronics to ensure optimum operation, stability and reliability. It has rich I/O connectivity with 4x HDMI, 2x USB 3.0, 1x USB 2.0, and 3x RJ45 for 2x Gigabit LAN and 1x RS232, with expansion features via 2x mPCIe and 1x UIM/SIM card slot for WiFi, Bluetooth or 3G/LTE functions. In addition, the system is built with hardware EDID emulation, a feature that allows system setup with a variety of screen configuration, power and signals, to troubleshoot itself without the need of resetting the unit when there is a problem.
