Individually Hand-tested: Every cable is checked right from the assembly line to ensure it performs at peak level. We examine each cable at its manufactured length between devices capable of supporting 4K (2160p) @ 60Hz.</br>Official HDMI Adopter: Mediabridge has been a recognized adopter by HDMI Licensing LLC. since 2007.</br>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.</br>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 that's true to the source.</br>Lifetime Warranty: We will catch virtually all manufacturing defects with our hand-testing process. For any concerns that may not surface until later you're still backed by our Limited Lifetime Warranty. We also have friendly USA-based customer support.</br></br>Product Description</br></br><b>Mediabridge ULTRA Series HDMI Cable</b><br/><br/>Connects a Blu-Ray player?? computer?? Apple TV??
