BZBGEAR BG-8K-DA18 1x8 HDMI 2.1 48Gbps Splitter

Single-source 8K splitter for eight displays

The BZBGEAR BG-8K-DA18 takes one HDMI 2.1 input and replicates it across eight HDMI outputs at up to 48 Gbps. It supports 8K at 60 Hz in 4:2:0 12-bit and 4K at 120 Hz in 4:4:4 12-bit. HDR10, HDR10+, Dolby Vision and HLG pass through unchanged. Audio formats include LPCM 7.1, Dolby TrueHD, Atmos and DTS-HD Master Audio. The unit suits installers feeding multiple screens from a single console, media player or PC. Builders who need more than eight outputs or a different input interface should look elsewhere.

Rack-mountable with locking power and EDID control

The aluminium chassis measures 250 mm by 104 mm by 30 mm and weighs 743 g; two mounting ears and four KM3*6 screws are included for 1U rack or surface installation. A 12 V 2.5 A multinational locking supply prevents accidental disconnection. Each output manages its own EDID, so the source sees a single sink while every display receives its native timing. Auto downscaling and HDR-to-SDR conversion per port handle mixed-resolution arrays without manual setup. Users without rack space or who rely on bus-powered splitters will find this unit less convenient.

Sustained 48 Gbps throughput with active cooling

The splitter maintains full 48 Gbps FRL bandwidth across all eight ports continuously, not just in short bursts. HDCP 2.3 encryption remains active on every link during extended sessions. VRR, ALLM, QMS, QFT and SBTM signalling pass through without added latency, keeping gaming and live-production workflows stable. The metal enclosure acts as a heatsink; no fan noise appears in the specifications. Installations in sealed cabinets without airflow should verify thermal headroom before committing.
