Overview
The OREI EX-165C HDMI Extender over Cat6 is a transmitter-and-receiver kit built to push an HDMI signal up to 165 feet through a single Cat5e or Cat6 ethernet cable — a practical fix for installations where a long HDMI run simply isn't an option. On the market since 2016, it has accumulated over 1,100 ratings and a solid track record that shorter-lived alternatives just can't match. At its mid-range price, this HDMI extender kit occupies a sensible middle ground between budget units and serious pro-AV gear, making it viable for home installers and IT teams alike. A dual-voltage power supply and international adapter come included, so cross-region deployments are covered. A composite rating of 4.2 out of 5 signals broad satisfaction, though it isn't a perfect score — which tells you something honest about its limitations.
Features & Benefits
At its core, this Cat6 signal extender delivers stable 1080p Full HD over a single ethernet cable run up to 165 feet. Worth stating clearly — this is not a 4K solution. If your source or display operates at 4K, the signal will downscale or behave inconsistently, so check your setup before buying. For 1080p content, performance holds up well. The IR passthrough works by transmitting remote control signals from the receiver end back toward the source, letting you operate a Blu-ray player or cable box from the far room without line-of-sight. A local loop-out at the transmitter keeps a second display active at the source end simultaneously. EDID management handles display handshaking automatically, and POC lets the receiver draw power through the cable itself, removing the need for a second wall adapter.
Best For
This HDMI extender kit is well-suited to anyone dealing with a distance problem HDMI cable alone can't solve. Home theater enthusiasts routing a signal through walls or ceilings to a projector or TV in another room are the obvious fit — particularly when Cat6 is already run through the building. Conference rooms, training spaces, and classrooms benefit from the clean, cable-efficient setup without visible video lag or quality loss at the display end. IT professionals managing equipment racks or test benches will appreciate both the plug-and-play setup and the IR control, since those environments often demand remote source operation without being physically present at the transmitter. If you need 4K support or HDR, though, look elsewhere — the OREI extender tops out at 1080p.
User Feedback
Across the review base, a consistent pattern emerges. Buyers who pair this Cat6 signal extender with quality Cat6 cable report clean, reliable video over the full 165-foot range — the keyword being quality cable, since inferior ethernet is a common culprit behind negative reviews. The IR passthrough gets singled out repeatedly as a deciding factor, especially by home theater buyers. On the downside, several users report trouble with 4K-capable sources that don't negotiate resolution cleanly, producing no signal or a flickering display. That 1080p ceiling is a hard one. A small number of users also mention needing a power cycle during initial setup, which is a minor but real quirk to plan for.
Pros
- Delivers clean, stable 1080p video over runs up to 165 feet on quality Cat6 cable.
- IR passthrough lets you control source devices from the display end — a feature many competing kits skip.
- The local loop-out port allows a second monitor to stay active at the source end simultaneously.
- POC support means the receiver can draw power through the ethernet cable, reducing adapter clutter.
- EDID management handles display handshaking automatically — no manual configuration required.
- Plug-and-play setup has been confirmed by hundreds of buyers; no driver installation needed.
- Metal enclosure provides EMI and RFI shielding, suitable for busy IT or rack environments.
- Dual-voltage power supply with international adapter included covers cross-region deployments out of the box.
- FCC, CE, and RoHS certified, passing the compliance bar for both commercial and home installations.
- A long market history since 2016 means well-documented real-world performance across a wide range of setups.
Cons
- Strictly limited to 1080p — not suitable for 4K sources or displays expecting higher resolution signals.
- Some 4K-capable source devices fail to downscale cleanly, resulting in no signal at all.
- Full 165-foot range is only reliable on quality Cat6; Cat5e users may experience signal instability near the limit.
- A small but notable share of buyers report needing a power cycle before the connection initializes properly.
- No support for HDMI audio return channel (ARC), which limits use with certain soundbar setups.
- The receiver still requires its own power in most setups unless POC is fully supported end-to-end.
- The kit only supports point-to-point extension; reaching multiple remote displays requires additional hardware.
- No HDR or advanced color space support — picture quality improvements beyond standard 1080p SDR are not possible.

Suitable for:
The OREI EX-165C HDMI Extender over Cat6 is a strong pick for anyone who needs to bridge a serious distance between an HDMI source and a display without ripping out walls to run new cable. Home theater owners who already have Cat6 ethernet installed — or who are willing to run it — will find it a clean, low-fuss solution for feeding a projector or TV in a room far removed from a media rack or set-top box. It also fits naturally into small business environments: conference rooms, training centers, and classrooms where a consistent 1080p video feed needs to reach a wall display from a source at the instructor's desk or AV cabinet. IT professionals managing equipment racks or test benches will appreciate both the hands-off EDID handling and the IR passthrough, which lets them operate source devices remotely without walking to the other end of the room. If your content is 1080p and your run is under 165 feet on quality Cat6, this kit reliably does exactly what it promises.
Not suitable for:
Anyone running a 4K display or working with a 4K-capable source device should look elsewhere — the OREI EX-165C HDMI Extender over Cat6 tops out at 1080p Full HD, and sources that try to negotiate a higher resolution can produce a blank screen or an unstable signal. If your setup exceeds the 165-foot distance, this kit simply will not cover it without a signal booster or a different product class entirely. Users planning to rely on Cat5e cable should also temper expectations: the full 165-foot range is best guaranteed on true Cat6, and Cat5e runs approaching that distance can introduce signal instability. Anyone expecting a 4K TV to reliably auto-downscale the signal will likely run into compatibility headaches that most buyers are not prepared for. It is also not the right choice for anyone who needs to distribute to more than two displays simultaneously, or for setups that depend on HDMI audio return channel functionality.
