4K 30 Hz KVM Extender Kit

This YINGHUA kit extends HDMI video and USB keyboard and mouse signals up to 120 metres over a single Cat5e or Cat6 cable. It includes a transmitter and a receiver, each with an AU power plug, and supports HDMI 1.4 with HDCP 1.4 compliance.

Installers needing long-range HDMI and USB

The extender suits integrators who must place a display and peripherals far from the source while keeping a local HDMI loop-out for a nearby monitor. IR pass-through allows remote control of the source device. Buyers who need 4K at higher refresh rates, HDR support or transmission beyond 120 metres should consider alternative products.

340 MHz bandwidth ceiling

The link tops out at 340 MHz pixel clock and 3.4 Gbps per lane, which limits 4K output to 30 Hz. This single bandwidth figure determines whether the extender can carry the required video format for a given installation.

Questions about this item

What cable type and maximum length does the YINGHUA 4K extender need between the TX and RX units?

The extender requires a Cat5e or Cat6 Ethernet cable up to 120 metres long to link the transmitter and receiver.

Which step is often missed when installing the IR control feature on this KVM extender?

Users often forget to connect the IR emitter to the TX and the IR receiver to the RX so the remote signal can pass over the Cat5e/6 link.

When should the AU power adapters supplied with the TX and RX be replaced?

Replace the AU plug power adapters if the extender shows unstable video, USB dropouts, or the units run excessively hot during operation.
