Switch two HDMI 2.1 sources to four displays at up to 8K@60Hz with independent downscaling and audio de-embedding on every output. The KanexPro SP-HDMI2X4-8K is a 48Gbps 2×4 HDMI matrix splitter that routes two sources to four screens — eliminating the need for a separate switcher, downscaler, or audio extractor in the rack.

Compliant with HDMI 2.1 and HDCP 2.3, the matrix splitter supports 8K@60Hz 4:2:0 12-bit, 8K@30Hz 4:4:4 12-bit, and 4K@120Hz 4:4:4 12-bit with HDR10, HDR10+, Dolby Vision, HLG, and ALLM/VRR pass-through. Each output independently downscales 8K to 4K or 2K and converts HDR to SDR for mixed-resolution display environments. Audio de-embedding delivers digital optical (up to 5.1CH) and balanced/unbalanced analog stereo with adjustable gain. A built-in HDMI signal generator aids diagnostics. Control via front panel, IR remote, RS-232, or API commands.

  • Routes 2 HDMI 2.1 sources to 4 displays at up to 8K@60Hz 4:2:0 12-bit with 48Gbps bandwidth — auto or manual input switching
  • HDCP 2.3 compliant with HDMI 2.1 — supports protected content across all input and output channels
  • HDR10, HDR10+, Dolby Vision, HLG pass-through with ALLM and VRR for low-latency gaming and cinematic playback
  • Independent 8K→4K/2K downscaling on each output — feed mixed-resolution displays from a single source without manual reconfiguration
  • Per-output HDR→SDR conversion preserves contrast and detail on non-HDR legacy displays
  • Audio de-embedding via digital optical (up to 5.1CH Dolby/DTS) and balanced/unbalanced analog stereo (L/R) with adjustable gain control
  • Built-in HDMI signal generator with 15 resolutions and 13 test patterns for on-site diagnostics and cable verification
  • Control via front panel buttons, IR remote, RS-232, and API commands — advanced EDID management with 16 presets, 2 user-defined, and pass-through mode
