Wireless 4K extender with loop-out

The BFKK kit sends 3840x2160 video at 30 Hz from a PC, camera, laptop or PS4/5 to a projector, HDTV or DSLR without cables. A transmitter and receiver pair covers up to 490 ft line-of-sight, while an HDMI loop-out on the transmitter keeps a local display active. The system targets educators, streamers and event crews who need mobility without running long HDMI runs.

H.265 compression and multi-receiver scaling

H.265 encoding shrinks the 4K stream so it fits the wireless link while preserving detail, and the hardware runs cool enough for extended sessions. One transmitter can feed up to four receivers; reach drops to 262 ft with two, 115 ft with three and 65 ft with four units. Plug-and-play operation means no driver installs or network configuration for the supported sources.

30 Hz ceiling and distance trade-offs

The 30 Hz refresh cap makes the kit unsuitable for high-frame-rate gaming or fast-motion sports production. Range figures assume clear line-of-sight; walls, metal structures or RF congestion will reduce usable distance below the quoted maximums. Buyers needing 60 Hz 4K, wired reliability or transmission through multiple floors should evaluate alternative solutions.
