1x8 HDMI Splitter Over Cat6

This HDMI splitter extends a single 4K source to eight displays using Cat6 cabling. It includes a local HDMI loopout for a nearby monitor. HDCP 2.2 compliance protects premium content. The unit suits installers needing long-distance distribution in commercial or residential settings.

Sustained 4K transmission stability

Cat6 or Cat7 cable carries 4K at 60 Hz up to 70 metres without signal degradation. Cat5 cable supports the same resolution up to 40 metres. The transmitter powers eight RJ45 outputs simultaneously while maintaining full-frequency IR and RS-232 control paths. EDID management via DIP switch keeps handshakes stable across all receivers.

70-metre 4K reach over Cat6

Maximum 4K 60 Hz distance is 70 metres on Cat6/7 and 40 metres on Cat5. This range decides whether the extender fits the installation. Shorter runs work on cheaper cable; longer runs require Cat6/7. No other specification overrides this distance limit.

Questions about this item

How much heat does the transmitter generate when running all day with eight Cat6 cables at 70m?

The TX unit is passively cooled and rated for continuous operation; its 12V 3A power adapter supplies the maximum needed power.

Which cables and displays must I already own to use the 1x8 splitter?

You need one HDMI source, eight Cat5e/6/6a/7 cables, and up to eight HDMI displays; IR and RS-232 accessories are included.

Will the loopout port on the transmitter work with my older 1080p projector while the eight receivers show 4K?

The loopout mirrors the input signal; EDID is managed by the 4-pin DIP switch on the TX so you can force a compatible resolution for all outputs.
