4K KVM Extender for Remote Workstations

This HDMI KVM extender set transmits 4K video and USB 2.0 signals over a single Cat5e or above cable up to 120m. It supports resolutions up to 4K@30Hz and 1080P@120Hz for high refresh rate gaming. Zero latency ensures real-time interaction between the source and remote display. Ideal for data centres, classrooms or home offices needing remote PC control.

Passive Cooling and Low Power Operation

The compact transmitter and receiver units operate silently without fans, drawing power from the included 12V 1A supplies. Zero latency transmission adds no processing delay to video or USB signals. HDCP 1.4 compliance maintains protected content playback across the link. Multichannel audio up to PCM 7.1ch passes through without degradation.

Upgrades Short Range HDMI and USB Cables

Replaces direct HDMI and USB runs limited to a few metres with a 120m Cat5e/6/7/7a link. The jump is worth it when the source and operator must be in separate rooms or secure areas. Three USB 2.0 ports on the receiver connect keyboard, mouse and peripherals like webcams or flash drives. Not for users needing USB 3.0 speeds or 4K@60Hz video bandwidth.

Questions about this item

How do I install the 4KEX120-KVM and what step is often missed?

Connect the transmitter to the source with the included 1.5m USB 2.0 Type-A to Type-B cable, link transmitter and receiver with a Cat5e/6/7/7a cable up to 120m, plug peripherals into the receiver's three USB 2.0 ports, then attach both 12V 1A power supplies; the step often missed is powering both units before expecting signal.

What maintenance or replacement will the 4KEX120-KVM need later?

The extender has no user-serviceable parts; maintenance is limited to checking that the Cat5e/6/7/7a cable and the two 12V 1A power supplies remain secure and undamaged; if a power supply fails, replace it with an equivalent 12V 1A unit.

What limit appears first under sustained use of the 4KEX120-KVM?

The primary sustained-use limit is the 120m maximum cable distance over Cat5e/6/7/7a; video bandwidth is capped at 4K@30Hz or 1080P@120Hz, and USB throughput is limited to 480Mbps per port, so resolution, refresh rate or peripheral speed will hit their ceilings before the extender itself degrades.
