ACT 4K HDMI 1.4 extender set over CAT6 UTP with IR support, 40 meters

The ACT AC7801 AV transmitter and receiver set extends HDMI signals over CAT6 UTP cable up to 40 meters while supporting resolutions up to 4K@30Hz (4096 x 2160). The kit includes a transmitter with a local HDMI loop output and a receiver powered via Power over Cable (PoC) from the transmitter. The set supports EDID copy, Chroma Sampling 4:4:4, an infrared transmitter and receiver for remote control, a screw-locked power connector on the transmitter and an integrated mounting bracket for installation.

Advantages

This HDMI 1.4 extender set enables 4K@30Hz transmission over CAT6 UTP up to 40 m and offers extended 1080p@60Hz range up to 70 m. Power over Cable (PoC) eliminates the need for a separate power supply at the receiver. A local HDMI output on the transmitter allows connecting a nearby screen. EDID copy ensures correct resolution negotiation between source and display, and included IR accessories provide remote control of the source device. The transmitter’s screw-locked power connector reduces the risk of accidental disconnection.

Suitable for

• Extending HDMI signals from media players, set-top boxes or PCs to a distant display
• Small meeting rooms, classrooms and digital signage installations up to 40 m
• Setups that require IR control of the source device
• Installations where the receiver should be powered remotely via PoC

How to use

Connect the HDMI source (for example a media player or PC) to the HDMI input of the transmitter and optionally connect a local monitor to the transmitter’s HDMI loop output. Run a CAT6 UTP cable between the transmitter and receiver units. Power the transmitter with the supplied 12 V DC adapter; the receiver will receive power via PoC over the CAT6 cable. Connect the display to the receiver’s HDMI output and use the included IR transmitter and receiver to control the source device if required. Use the EDID copy feature to ensure proper resolution negotiation between source and display.

Recommendations

For reliable 4K@30Hz performance use high-quality CAT6 UTP cable and avoid long runs with poor connectors; secure the transmitter’s power plug with the screw lock to prevent accidental disconnection. When cascading multiple extenders, verify EDID settings and test each link at the desired resolution.
