Mediabridge HDMI Cable (6 Feet) Supports 4K@60Hz, High Speed, Hand-Tested, HDMI 2.0 Ready - UHD, 18Gbps, Audio Return Channel INDIVIDUALLY HAND-TESTED: Every cable is checked right from the assembly line to ensure it performs at peak level. Unlike many competing brands that test random cables from large batches, we examine each cable at its manufactured length, between devices capable of supporting 4K (2160p) @ 60Hz. PREMIUM BUILD QUALITY: 28AWG pure Copper conductors, tri-shielding & a gold-plated full metal jacket provide optimal sound & picture quality thats true to the source. WHEN WE SAY 60Hz, WE MEAN IT: Most basic 4K players & TVs 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. LIFETIME WARRANTY: We will catch virtually all manufacturing defects with our hand-testing process. For any concerns that may not surface until later, youre still backed by our Limited Lifetime Warranty. We also have friendly, USA-based customer support...If you even need it!
