4K HDMI KVM USB Extender

The WUQ KVM extender transmits 4K video at 30Hz and 1080p at 60Hz over a single Cat5e or Cat6 cable up to 100 metres. Four USB 2.0 ports on the receiver connect keyboards, mice, cameras and headsets. PoE support under the 802.3AF standard lets the unit draw power from a compatible switch, removing the need for a local power adapter at the remote end.

Latency and audio performance

End-to-end latency stays below 50 ms, keeping keyboard and mouse response tight for interactive tasks. The extender passes HDMI audio in raw formats including 2-channel, 5.1, 7.1, DTS and Dolby, plus a separate 3.5 mm analogue audio path for speakers or microphones. No compression artefacts are introduced, preserving image quality for medical imaging or digital signage.

Build integration and limits

The compact transmitter and receiver each measure 4.72 by 3.15 by 0.79 inches and use plug-in mounting, so they fit on a desk or behind a display without brackets. A Gigabit PoE switch is recommended to supply both units reliably. The link tops out at 4K 30Hz, so workflows needing 4K 60Hz or higher refresh rates will require a different solution.

Questions about this item

How do I install the WUQ 4K HDMI KVM USB Extender and what step is often missed?

Connect the transmitter to the source via HDMI and USB, link both units with a Cat5e/6 cable up to 100 m, power the transmitter using an 802.3AF PoE switch, then plug peripherals into the receiver's four USB 2.0 ports; the step often missed is using a Gigabit PoE switch to ensure stable power delivery.

What maintenance or replacement will the WUQ 4K HDMI KVM USB Extender need later?

The unit has no user-serviceable parts; maintenance is limited to checking Cat5e/6 cable integrity and PoE switch health, while the 3.5 mm audio jack and four USB 2.0 ports may wear after repeated insertions and require cable or hub replacement.

What limit appears first during sustained use of the WUQ 4K HDMI KVM USB Extender?

The primary limit is the 4K@30 Hz video ceiling combined with sub-50 ms latency; pushing higher resolutions or refresh rates such as 1080p@60 Hz is supported, but 4K cannot exceed 30 Hz, and USB 2.0 bandwidth caps peripheral throughput.
