1080p HDMI Extender Over Cat5e/6 165ft - Low Latency HDMI Extension

In this review of the SIIG 1080p HDMI Extender over Cat5e/6, the bottom line is simple: it is for anyone who needs a reliable, no-compression HDMI link to a remote display up to 165ft away. The unit's single biggest selling point is its ability to deliver full 1080p and 3D video with low latency while also passing IR control back to the source, making it a practical choice for home theaters, conference rooms, or kiosk setups where the source and display are separated. The reviewer found setup straightforward and the metal housings reassuring for long-term use.

Key Features

• 165ft HDMI extension: Extends HDMI signals over a single Cat5e/6 cable up to 165ft to place source and display far apart without losing Full HD quality.
• 1080p and 3D support: Delivers uncompressed video up to 1080p and supports 3D formats to preserve image fidelity for movies and game consoles.
• IR remote passthrough: Allows control of the source device from the remote display location, so users can operate DVD players or set-top boxes without returning to the source.
• Local HDMI loopout: Built-in HDMI output on the transmitter lets installers monitor the source locally while the remote display shows the same feed.
• Low latency transmission: Designed for near real-time audio/video transfer, which is important for gaming and presentations that require minimal lag.
• Durable metal housing: Premium metal cases provide better heat dissipation and a more durable installation for constant operation.

Who It's For

This extender is aimed at homeowners building a remote projector or TV installation, AV installers setting up conference rooms, and small businesses deploying displays where the source must be kept in a secure or central closet. Its support for IR passthrough is particularly useful when users need to control a remote player without running extra control wiring.

It is less appropriate for users who need resolutions above 1080p (such as native 4K) or for projects that require networked, packetized AV over IP solutions; those buyers should look for products explicitly supporting higher resolutions or professional AV-over-IP systems.
