Portable U-Disk Wireless HDMI Extender

The TIMBOOTECH G57 kit uses a compact U-disk form factor to transmit 4K-decoded video at 1080P output from a laptop, camera or TV box to a monitor, HDTV or projector. Dual-band 2.4G and 5.8GHz operation delivers a stable link up to 328 feet without requiring Wi-Fi, Bluetooth or driver installation. Up to eight transmitters can pair with a single receiver for quick source switching.

Replaces Cabled HDMI Runs

This extender removes the need for long HDMI cables across rooms, halls or outdoor spaces where routing is impractical or unsafe. The 5-second auto-pairing means the link is ready almost instantly, so the jump from a wired connection is worth it whenever setup speed and mobility matter more than a permanent installation.

Sustained Dual-Band Streaming

Under continuous use the dual-band radio maintains the 328-foot range by hopping between 2.4G and 5.8GHz to avoid local interference. Multiple kits can operate in the same area without cross-talk, and the stereo audio path stays locked to the video stream throughout extended sessions.

Questions about this item

What HDMI port does the transmitter need on my laptop or camera?

The G57 transmitter plugs into any standard HDMI output on your laptop, camera or TV box; no special port version is required.

How do I pair the transmitter and receiver, and what step causes most failures?

Insert both units into HDMI ports, power them via USB, then wait for the 5-second auto-pairing; the common mistake is not supplying USB power to both ends.

When should I replace the USB power cables that run the transmitter and receiver?

Replace the cables if the units fail to power on, show intermittent video drop-outs, or the connectors become loose after repeated plugging.
