Certified 8K Performance & Bandwidth
This cable is certified by an HDMI Authorized Test Center. It supports 8K at 60Hz and 4K at 120Hz resolutions. The 48Gbps data transfer rate handles high-frame-rate content without compression. So, you get sharp images and smooth motion for gaming or video editing.
Enhanced Audio Return Channel (eARC)
eARC support enables uncompressed 5.1 and 7.1 digital audio channels. It is compatible with DTS-HD Master Audio, DTS:X, Dolby TrueHD, and Dolby Atmos. This ensures high-fidelity sound from your TV to an audio system. Also, HDCP 2.3 secures your video and audio content during playback.
Durable Construction & EMI Protection
The cable uses an aluminum mylar foil with braided shielding. This design reduces electromagnetic interference (EMI) from wireless devices. The TPE jacket is flexible and non-toxic, supporting environmental sustainability. In practice, this improves signal integrity and long-term durability.
Gold-Plated Connectors & Reliability
Both connectors feature gold plating to prevent corrosion. They are tested to withstand 10,000+ insertions. The die-cast aluminium sub-structure shielding further prevents signal degradation. So, you maintain premium video quality over time.
