120m HDMI extender

Start with distance needs, then decide between IP-based extension and simple point-to-point links. For this group, some models extend over TCP/IP using an Ethernet switch and a single Cat5e/6 cable, which means you can place displays across rooms without bulky HDMI runs. Look for features like 4K capability, 3.5mm stereo audio outputs on both TX and RX, and add-ons such as IR control or USB mouse/keyboard extension. This helps ensure compatibility with your display chain while keeping power use and heat low.

The key complexity is understanding the supported video mode and its refresh rate over long distances. Some extenders advertise 4K at 120 metres, while others deliver 4K only at 30Hz depending on the implementation. USB, IR, and audio passthrough capabilities vary as well, with TX/RX units sometimes providing separate 3.5mm audio outputs and USB extension. Check the specific combination of resolution, Hz, and peripheral support to ensure your gaming, movie, or presentation workflow remains smooth across the extended link.

A home cinema or multi-room media setup is ideal, where you want a single source to drive displays positioned far apart. These extenders are designed to transmit signal up to 120 metres using Cat5e/6 cables, letting you place a projector, TV, or monitor in separate rooms or zones. They’re also suitable for small business environments needing long-distance display connectivity, while preserving picture quality and enabling optional peripherals like USB mice or IR remotes.

Use a high-quality Cat5e/6 cable as recommended to preserve signal integrity over long runs, and connect both TX and RX units correctly. Take advantage of features like USB mouse/keyboard extension and IR control if you need remote interaction with the source. Ensure the devices you connect support the HDMI version in use (HDMI 1.4b or higher) and keep power supply within the extender’s design specifications to prevent overheating. Regularly inspect cables for wear and avoid sharp bends.

Don’t assume every 4K claim guarantees smooth performance at full length; verify the actual supported resolution and refresh rate over 120 metres. Avoid using subpar cables, as poor-quality Cat5e/6 can degrade the image. Don’t overlook periphery support like USB, IR, and local audio output, which can be essential for your setup. Finally, don’t mix IP-based extenders with non-IP devices unless the system designer confirms full compatibility across all endpoints.

If you need remote input control, choose KVM-enabled extenders that support USB mouse/keyboard and IR alongside HDMI transmission. The TX/RX pairs in this group often include such features, enabling seamless interaction with the source from the display side. For purely display purposes, a standard HDMI extender over Cat5e/6 may suffice and can offer simpler installation with lower latency, provided it meets your required resolution and distance.
