## Summary description

ATEN KHEXT40 HDMI extender transmits HDMI video and audio up to 60 meters using two Cat5e cables. Designed for installations where long-distance HDMI connection is needed, it supports uncompressed signal extension for displays, meeting rooms, digital signage and classrooms. The solution reduces the need for long HDMI cables and enables flexible placement of source and display devices.

## Long description

ATEN KHEXT40 HDMI extender transmits HDMI video and audio up to 60 m using two Cat5e/Cat6/Cat7 cables. The kit includes transmitter and receiver units and draws power from the HDMI connector, so no external power supply is required under normal conditions. It supports HDMI 1.3 and HDCP, and carries common CEC control protocols for integrated control of connected devices.
Advantages
The extender supports Full HD resolutions (480i, 480p, 720i, 720p, 1080i and 1080p) and allows signal extension up to 60 m at 1080i or 40 m at 1080p when using two quality Cat cables. It requires only two Catx cables for the link and works without an additional power adapter in standard setups. When higher distances or greater stability are needed, the unit can be powered externally via a compatible adapter.
Suitable for
Conference rooms and meeting spaces
Classrooms and lecture halls
Digital signage and public displays
AV installations where long-distance HDMI routing is required

How to use

Set the display resolution to a supported mode and verify HDCP/CEC settings if control features are required. If the system shows instability at long distances, connect an optional external power adapter to the unit to ensure reliable operation.
Usage recommendations
For reliable operation at resolutions of 720p and above over distances greater than 30 m, use high-quality UTP cable such as Cat6 AWG23 solid copper. If distance is extreme or HDMI power is insufficient, use the compatible external power adapter (ppadapter-13).
