High-end High-speed Hdmi Cable with Ethernet Hdmi 2.0/10ft(3m) Resolution Support 4k(60hz) Golden Plating Copper Connector/double Magnet Ring (ST 9.8ft) INDIVIDUALLY HAND-TESTED: Every cable is checked right from the assembly line to ensure it performs at peak level. Unlike other brands that test random cables from large batches, we examine each cable at its manufactured length, between devices capable of supporting 4K (2160p) @ 60Hz. OFFICIAL HDMI ADOPTER: Holtek has been a recognized adopter by HDMI Licensing, LLC. since 2007. Don't let our competitors fool you; If it's not HDMI official, then who knows what you're plugging into your valuables? WHEN WE SAY 4K, WE MEAN IT: Most basic 4K players & TV's today only support up to 30Hz, which is quite the downgrade compared to 60Hz. Fortunately, our cables are built with the highest specs to make sure they work with even the most premium devices. Note: Due to varying HDMI standards, no cable on the market can guarantee universal 60Hz compatibility. SUPPORT FOR ALL: Fear not, for it supports all HDMI 2.0b functions including 18Gbps transfer speed, 4K, UHD, 3D, 48-Bit Deep Color, HDR video & ARC. 28AWG pure Copper conductors, tri-shielding & a gold-plated full metal jacket provide optimal sound & picture quality that's true to the source.
