1x4 HDMI 2.1 Splitter for Multi-Display Setups

The BG-8K-DA14A-G2 distributes a single HDMI 2.1 source to four displays simultaneously. It supports resolutions up to 8K at 60 Hz and 4K at 120 Hz with 12-bit colour depth. HDCP 2.3 compliance ensures protected content plays correctly on connected devices. This unit suits home theatres, gaming rigs and professional AV installations needing identical output across multiple screens.

Sustained 48 Gbps Bandwidth with Auto Downscaling

The splitter maintains a full 48 Gbps FRL signal path alongside 18 Gbps TMDS compatibility for legacy sources. Auto downscaling allows each output to negotiate its own maximum resolution without forcing the source to the lowest common denominator. VRR, ALLM and QFT pass-through preserve variable refresh rates and low-latency modes during extended gaming sessions. HDR10+, Dolby Vision and HLG metadata travel unchanged across all four outputs for consistent high dynamic range performance.

Aluminium Enclosure with Optical and Analog Audio

A sturdy aluminium chassis provides shielding and passive cooling for continuous operation. One HDMI input and four HDMI outputs use standard Type A 19-pin connectors for broad cable compatibility. Audio de-embedding is handled by a dedicated optical S/PDIF port and a 3.5 mm stereo mini-jack, letting you feed external sound systems without an AV receiver. Advanced EDID management ensures reliable handshakes between source and displays day after day.

Questions about this item

Does the BG-8K-DA14A-G2 generate noticeable heat or fan noise when distributing 8K60 signals all day?

The unit is a compact HDMI 2.1 splitter with no fan listed in its specifications; it handles 48 Gbps FRL bandwidth passively, so heat and noise remain minimal during continuous operation.

Which cables and displays must I already own to use the 1x4 HDMI 2.1 splitter with audio de-embedding?

You need one HDMI Type A source cable, up to four HDMI Type A display cables, plus either an optical S/PDIF cable or a 3.5 mm stereo mini-jack cable for the extracted audio outputs.

Will the BG-8K-DA14A-G2 downscale 8K60 content automatically for older 4K60 or 1080p screens I want to keep?

Yes, the manufacturer highlights auto downscaling, so each of the four outputs can negotiate its own EDID and display 8K60, 4K120, 4K60 or 1080p without manual setup.
