NTI SPLITMUX-4K18GB-4 4K 18Gbps HDMI Quad Screen Multiviewer

The NTI SPLITMUX-4K18GB-4 4K 18Gbps HDMI Quad Screen Splitter/Multiviewer displays real-time video from four HDMI 2.0 sources simultaneously on a single monitor at resolutions up to 4096x2160 @ 60Hz. Control rooms, security operations, broadcast monitoring, and boardrooms get fluid 60 fps performance in quad, picture-in-picture, full-screen, or fully custom windowed layouts, with each input independently scaled from its native resolution to the output.

Every input and the output are HDCP 2.2/1.4 compliant, with 36-bit input color and support for RGB and YCbCr 4:4:4/4:2:2/4:2:0 formats. Audio switching is independent of video: HDMI-embedded audio from the four sources can be switched or four-channel stereo mixed, with adjustable gain and VU indicators. Custom text labels identify each window, layouts can be saved to ten presets with zoom, pan, and crop, and multiple units cascade for larger arrays.

Configuration and control are available from the front panel, on-screen display, keyboard/mouse, RS232, and Ethernet — including a built-in HTTP/HTTPS web server for up to 16 simultaneous users, Telnet, and an HTTP REST API with JSON responses for integration into automation systems. The included 1RU rackmount kit with cable management shelf installs the compact chassis cleanly, and configuration backup/restore protects the setup. CE, RoHS, and TAA compliant, with a two-year manufacturer warranty.
