## Summary description

ATEN khrep04 HDMI repeater extends HDMI signals to improve transmission over longer distances. It supports 4Kx2K resolution and 3D formats and is designed to maintain signal integrity up to 40 meters.

## Long description

It supports HDMI 1.4b features including 3D and 4Kx2K@30Hz, is HDCP 1.4 compatible and draws power from the HDMI bus, so no external power supply is required.

Use appropriate-length HDMI cables (for example two 20 m cables) with the recommended 24 AWG copper conductor to achieve the stated extension distance. The repeater receives power through the HDMI connection, so no separate power adapter is necessary. After installation, verify the display resolution and HDCP status on the source and sink devices.
Usage recommendations
For best results, use high-quality HDMI cables with 24 AWG copper conductors and avoid exceeding the recommended combined cable length. If image issues persist, check connectors and cable integrity and ensure source and display settings match supported resolutions and HDCP requirements.
