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.

HDMI cables run in the DIRECTION OF THE VIDEO SIGNAL. An HDMI connecting a video source (such as an EE box, Sky Q, Bluray player etc.) will run toward the display (such as a TV). An HDMI connecting a soundbar will also run toward the display. Soundbars just receive audio from the TV via the eARC or ARC connection. Since video sources sometimes connect to soundbars, the video signal would run toward the display. This is a use case of the Audio Return Channel (ARC).
