4K HDMI over Ethernet Extender over CAT6/CAT7 - Reliable 164 ft Range

In this review the OREI 4K HDMI over Ethernet Extender is evaluated for users who need to extend HDMI signals without running long HDMI cables. The bottom line: it is best for small offices, classrooms, and home theater setups that require a stable 4K@30Hz or 1080p@60Hz feed up to 50 m (164 ft) over a CAT6 or CAT7 cable. The reviewer found its combination of a local HDMI loop-out, IR pass-through, and M-JPEG processing makes it a practical, cost-effective solution for extending displays while keeping setup straightforward.

Key Features

• 4K and 1080p support: Transmits 4K@30Hz and 1080p@60Hz signals so both ultra HD and Full HD sources can be used without reconfiguration.
• Long-distance extension: Sends HDMI signals up to 50 m (164 ft) over CAT6/CAT7 cable for a reliable display link across rooms or floors.
• HDMI loop-out: The transmitter includes an HDMI loop-out so a local monitor can be connected while the remote screen receives the same signal.
• M-JPEG compression: Uses M-JPEG processing to keep image quality high with minimal visible loss across the Ethernet link.
• IR remote pass-through: Includes IR Tx/Rx so the source device can be controlled from the remote location, simplifying media setups.
• Complete kit and power options: Ships with transmitter, receiver, IR cables, two 5V DC adapters and an international power adapter for flexible installation.

Who It's For

The extender is ideal for users who need to place a display far from the source without running long HDMI cable runs, such as conference rooms, classrooms, lobby signage, or living rooms where the source sits by an AV cabinet. It suits people who want a simple hardware solution with local monitoring via the loop-out and the convenience of IR control.

It is less appropriate for extremely long runs beyond the specified 50 m or for situations that demand 4K@60Hz or HDR pass-through, since the unit is specified for 4K@30Hz. Buyers needing uncompressed, zero-latency professional video transport for high-frame-rate gaming should consider other solutions.

Pros & Cons

Pros

• Reliable picture quality for both 4K@30Hz and 1080p@60Hz sources with generally strong customer feedback on picture quality.
• Easy installation and setup, with customers reporting successful runs over Cat5e and Cat6 at useful distances.
• Built solidly with good connectivity options including HDMI loop-out and IR pass-through for remote control.
• Package includes power adapters and IR cables so installations are complete out of the box.

Cons

• Not designed for 4K@60Hz or HDR workflows, which limits appeal for some high-performance video applications.
• Some customers have noted concerns about long-term durability, so heavy commercial deployments may want to plan for regular checks.
