4x1 HDMI and USB-C 2.1 video switch

The BZBGEAR BG-8K-HCS41 routes three HDMI 2.1 sources and one USB-C source to a single HDMI display. It handles 8K at 60 Hz on HDMI and 8K at 30 Hz on USB-C, making it suitable for home-theatre enthusiasts, gamers and professional AV installers who need to share one screen across multiple devices.

48 Gbps FRL bandwidth on HDMI inputs

The HDMI ports support up to 48 Gbps FRL and 18 Gbps TMDS signalling, while the USB-C input reaches 32 Gbps. This bandwidth ceiling determines whether your 8K60 or 4K120 sources can pass full 4:4:4 colour without compression, so verify your source and cable specifications match these limits before purchase.

Passive cooling in a slim enclosure

The unit measures 145 mm by 68 mm by 18 mm and weighs 258 g with no moving parts, so it runs silently and draws minimal power from the included 5 V 1 A supply. Typical operation stays cool to the touch, adding no audible noise or noticeable heat to a rack or desktop setup.

Questions about this item

What does the 48 Gbps HDMI bandwidth deliver on a real display?

The 48 Gbps FRL link carries 8K at 60 Hz 4:2:0 12-bit or 4K at 120 Hz 4:4:4 12-bit to a compatible screen.

How does the USB-C 32 Gbps limit affect video output?

USB-C input maxes out at 8K 30 Hz 4:2:2 10-bit or 4K 120 Hz 4:2:2 10-bit because the 32 Gbps ceiling is lower than the HDMI inputs.

Will the 145 mm wide unit fit in a shallow rack shelf?

At 145 mm wide, 68 mm deep and 18 mm high it sits in a 1 U slot or on a desk with only a few centimetres of clearance.
