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.
