WRIARICH HDMI 2.1 Splitter 1×4 8K@60Hz 4K@120Hz 48Gbps HDCP 2.3

1×4 HDMI 2.1 Splitter for 8K mirroring

This HDMI 2.1 splitter takes one source and mirrors it to four displays simultaneously. It supports 8K at 60 Hz, 4K at 120 Hz and 1080P at 240 Hz with HDR, Dolby Vision and VRR. The unit only duplicates the input signal and cannot extend different content across screens. Gamers and installers needing identical output on multiple monitors will find it suitable.

Fits a build with one source and four screens

Connect a single HDMI source to the input and run up to four HDMI cables to monitors or projectors. The aluminium alloy housing dissipates heat without active cooling, keeping signal transmission stable at 48 Gbps per port. Cable length limits depend on resolution: 1.5 m at 8K, 2.5 m at 4K and 5 m at 1080P using AWG26 cables. All four outputs display the same resolution, matching the lowest common capability among the connected displays.

Sustained load behaviour with passive cooling

The aluminium chassis handles continuous 48 Gbps throughput across all ports without throttling. Audio formats including Dolby HD, DTS HD, Dolby Atmos and LPCM pass through unchanged during extended sessions. Because the splitter mirrors the lowest resolution detected, a single 1080P display will limit the other three outputs to 1080P even if they support higher modes. HDCP 2.3 compliance is maintained throughout prolonged operation.
