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: 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 thats true to the source. 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
