30-metre HDMI extender over Cat-5E/6

Extend HDMI signals up to 30 metres or 100 feet using double Cat-5E or Cat-6 RJ45 cable. The 4XEM 4XHDMIEXT30M replaces costly long-run HDMI cables with affordable twisted-pair wiring. It supports full 1080p resolution and HDMI 1.2 protocol without signal degradation. Installation completes in minutes for integrators and home users alike.

Passive transmission with no external power

The extender operates without a separate power supply, drawing only what the HDMI source provides. This keeps the setup silent and eliminates an extra wall outlet at the display end. Typical power draw stays negligible during normal 1080p playback. No fan noise or heat buildup occurs in standard indoor environments.

HDMI 1.2 and 1080p ceiling

The single decisive specification is the HDMI 1.2 protocol limit, which caps video at 1080p resolution. Buyers needing 4K, HDR, 3D or higher refresh rates cannot use this extender. It suits legacy Blu-ray players, older PCs and digital-signage loops that stay at 1080p. Systems requiring newer HDMI features will need a different solution.

Questions about this item

How do I connect the 4XHDMIEXT30M using double Cat-5E or Cat-6 cables?

Connect one Cat-5E or Cat-6 cable to each RJ45 port on both the transmitter and receiver units, then link the transmitter to your HDMI source and the receiver to your display. The step people miss is using two separate cables instead of a single run.

What maintenance will the 4XHDMIEXT30M need over time?

The extender has no moving parts or replaceable modules. Periodically check that both RJ45 connections stay firmly seated and that the Cat-5E or Cat-6 cables show no kinks or jacket damage.

What resolution limit appears first during a long 30 m run with the 4XHDMIEXT30M?

The extender supports 1080p at 30 meters over Cat-5E or Cat-6. Pushing beyond 1080p or exceeding the 30 m distance is where signal degradation will appear first.
