Wireless HDMI USB-C extender kit

The J-Tech Digital kit transmits uncompressed 4K 30Hz or 1080p 120Hz video up to 80 feet over the 60GHz millimetre-wave band. It connects an HDMI or USB-C source to an HDMI display with zero latency for presentations, desktop use and gaming.

USB hub and fast charging on the transmitter

When a USB-C source is used the transmitter provides two USB-A ports for peripherals and a secondary USB-C port that supports fast charging for phones or tablets. This turns the extender into a small dock for laptops during meetings.

4K 30Hz and 1080p 120Hz capacity with 7.1 audio

The kit handles 4K at 30Hz and 1080p at 120Hz comfortably, passing Dolby TrueHD, DTS-HD Master Audio and LPCM up to 7.1 channels. It cannot carry higher refresh rates at 4K or resolutions beyond 4K, and requires direct line of sight for the 80-foot range.

Questions about this item

Will the USB-C charging port on the transmitter need a separate power adapter later?

The transmitter includes a USB-C port that supports fast charging for phones and tablets while the kit is powered, so no extra adapter is required for that port.

What video limit appears first during a long presentation — distance or frame rate?

The wireless link reaches up to 80 ft with clear line of sight, and the highest sustained formats are 4K at 30 Hz or 1080p at 120 Hz.

How much heat or fan noise does the receiver produce when running all day?

The receiver and transmitter operate on the 60 GHz millimeter wave band with zero latency, and the design has no moving parts, so heat and noise stay minimal during continuous use.
