ROFAVEZCO HDMI Extender Over Ethernet 4K 60Hz (Uncompressed 18G) with RS232, PoE, IR & HDCP 2.2

If you’re trying to push an HDMI signal further without messy, long HDMI cables, this ROFAVEZCO HDMI extender is built for that job. It’s an HDBT-style “HDMI over Ethernet” solution aimed at 4K60 at up to 40m over a single Cat5e/Cat6/Cat7 run, with additional control and compatibility features for real-world home AV.

The headline is distance and signal handling, but it’s also the extras that make or break a purchase: bidirectional IR, RS232 for control, PoE support, plus EDID management. On paper, it’s a fairly feature-heavy extender, and that’s usually a good sign if your setup includes streaming boxes, a control system, and you want fewer headaches around handshakes and remote control.

The essentials

This ROFAVEZCO extender transmits an HDMI signal over a single Cat5e/Cat6/Cat7 cable. The unit is specified to carry 4K60Hz (including YUV 4:4:4) uncompressed, with bandwidth up to 18G/bps. For the long-run reality in UK homes (where wall runs and tidy routing matter), it also claims a practical reach of up to 40m for 4K60.

It’s not just video either. You get audio passthrough support for formats such as Dolby TrueHD, DTS-HD Master Audio, DTS:X, and AC3, plus PCM 7.1. If you’re building a wall-mounted TV setup, or you need a source like a console or streaming box to sit in a cabinet away from the TV, this kind of feature set is what you’ll want.

What you’ll notice day to day

In use, an HDMI extender only feels “worth it” when day-to-day behaviour is stable: remotes still work, control systems can manage the device, and the TV doesn’t keep re-negotiating settings.

This model includes: - Bidirectional IR, so you can send and receive IR commands (useful if your source is hidden behind a TV wall or in an equipment rack). - RS232, positioned for integration with control systems (the description calls out examples such as Control4 and Harmony). - CEC passthrough, which can help keep certain “turn on/off” behaviours from becoming a hassle.

There’s also EDID management with three options (4K/2K (1080P)/Copy). EDID is one of those things that can sound technical, but it matters because it affects compatibility during initial handshake—especially with TVs and sources that aren’t always “plug and forget”.

One limitation to keep in mind: extenders can still be fussy depending on your exact cable quality and installation conditions. So while the spec quotes strong ranges, it’s wise to plan your Cat cable run properly and avoid dodgy terminations.

Video and audio capability (how it’s positioned)

The spec focuses on high-demand signals: HDR support and 4:4:4 video at 4K60. It references HDR 8-bit, and gives further detail for HDR 4:2:2 at 10-bit and HDR 4:2:0 at 12-bit, plus HDR10 support.

If your viewing setup involves HDR content and you care about keeping the picture as faithful as possible, this is the kind of extender that’s designed for that rather than downgrading aggressively.

On audio, the extender supports a range of surround formats, including the ones people usually care about from streaming apps and home cinema sources. You can’t assume it will perfectly match every niche audio edge case, but the listed compatibility suggests it’s built with modern AV use in mind.

Compatibility and security bits you should check first

HDCP matters if you’re worried about stutter, black screens, or compatibility with streaming services. This extender supports HDCP 2.2, and the description specifically notes devices such as Roku 4, amazon Fire TV / Fire Stick, Xbox One S, PS3, PS4 Pro, cable/satellite decoders, PC/laptop, HD cameras and DVRs.

It also mentions HDCP 2.2 devices in the context of performance, which is a helpful buying signal. Still, you should check your exact source devices and whether they output 4K60 HDR in the way you expect—because different sources handle HDR and handshakes slightly differently.

Installation and physical design

The ROFAVEZCO is described as ultra slim / mini, in a form factor similar to a smartphone, with an emphasis on being able to hide the unit behind a TV. That’s a practical advantage if you’re trying to keep the back of the television tidy.

The interfaces are on one side for cleaner cable routing, and there’s mention of mounting support and a bracket/brace-style approach for easier installation. It also includes a threaded power adapter that is designed to avoid accidental disconnection, and the adapter can be locked in place for a more secure fit.

That “don’t wobble, don’t come loose” detail is genuinely important with wall-mounted setups. Less fiddling later usually means fewer returns.

Final verdict

It’s a good fit if you need a tidier way to extend HDMI over a single Cat5e/Cat6/Cat7 run, want 4K60 (up to 40m as specified), and you’ll actually use the extras like IR control, RS232 integration, and EDID management. You’re also likely to appreciate it if your setup includes HDR sources and you care about HDCP 2.2 compatibility.

You may want to skip it if your requirement is very simple (short distance, one source, no control integration), because this is positioned as a feature-rich extender rather than a bare-bones, minimal-cost fix. And if you’re not confident about cable quality/installation, it can be the kind of spec-driven product that exposes weaknesses in the build.

Quick FAQ

How far can it extend 4K60?

The description specifies up to 40m for 4K60 over Cat5e/Cat6/Cat7. For 1080P, it quotes a longer reach (up to 70m as stated).

Does it support HDR and HDCP 2.2?

Yes—HDR is referenced (including HDR10), and it supports HDCP 2.2 per the provided details.

Is there remote control support?

The extender includes bidirectional IR, which is intended to help control your source when it’s located away from the TV.

What’s EDID management for?

EDID management provides options (4K/2K (1080P)/Copy). In practice, that helps with HDMI handshake compatibility between source and display.

Does it work with a control system like Control4/Harmony?

The description explicitly mentions integration with control systems such as Control4 and Harmony via the features listed, including RS232.
