What matters when buying HDMI

HDMI is a data connection, so the useful question is not whether a cable sounds better but whether it carries the bandwidth your equipment needs over the distance you need it. Get that right and the picture is either perfect or obviously broken, with very little in between.

Match the specification to the source. HDMI 2.0 covers 4K at 60Hz and suits most streaming and disc playback. HDMI 2.1 at 48Gbps is required for 8K, 4K at 120Hz, variable refresh rate and the full gaming feature set. eARC support matters if you send audio back from a television to an amplifier or soundbar.

Length is where most problems start. Copper HDMI becomes unreliable as runs get longer, particularly at higher bandwidths, and the failure is usually intermittent sparkles or dropouts rather than a clean blank screen. Beyond around 5m at 4K, or 3m at 8K, active or fibre optic cable is the safer specification. Tell us the distance and the source equipment and we will confirm what will work.

HDMI over IP, sometimes called AV over IP, converts video and audio into IP packets that can be distributed across a standard Ethernet network. This approach allows for scalable and flexible AV systems with extended reach, simplified control, and cost-effective multi-display installations. CYP Europe’s AV over IP solutions provide future-ready performance that integrates seamlessly into modern networks.

HDMI 2.1 offers significantly higher bandwidth than HDMI 2.0 (48Gbps vs 18Gbps), supporting 4K at 120Hz, 8K at 60Hz, Dynamic HDR, and advanced gaming features such as Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). These upgrades provide smoother visuals and better sound when used with compatible devices.

Yes. Ultra High Speed HDMI cables are certified to handle the full 48Gbps bandwidth required for 4K/120Hz and 8K signals. They also ensure compatibility with features like eARC and Dynamic HDR for optimal performance.

Passive HDMI cables typically work up to 5–7m without issues. For longer runs, use active HDMI or fibre optic HDMI cables, which maintain full 4K/8K signal integrity over extended distances.

Yes. HDMI is backward compatible, meaning newer cables work with older HDMI devices. With adapters, HDMI can also connect to DVI, though DVI does not carry audio.

Absolutely. HDMI transmits both digital video and multi-channel audio, including Dolby Atmos and DTS:X, through a single cable for a clean, high-fidelity connection.

These devices allow one or multiple HDMI sources to feed multiple displays. A splitter duplicates the signal, while a matrix switch lets you send different inputs to different screens.

For distances over 10m, use active HDMI, HDBaseT extenders, or fibre HDMI cables. These maintain 4K/8K signal quality without loss.

Use an EDID manager or compatible distribution amplifier. This ensures all connected devices communicate correctly and avoid handshake issues.

HDMI 2.1 introduces eARC (Enhanced Audio Return Channel) as an improvement over HDMI 2.0's ARC. By utilising the higher bandwidth capabilities of HDMI 2.1, eARC can send uncompressed multi-channel audio from your TV to your amplifier/speakers. Similarly, the higher bandwidth of the A/V channels of HDMI 2.1 also support uncompressed multi-channel audio from your source to your amplifier/speakers. The higher bandwidth of HDMI 2.1 is also suited for I2S connections to support a wider range of resolutions.
