The Premium Certified HDMI Cables with Ethernet have undergone rigorous testing to verify that they comply with the HDMI 2.0b specification and can deliver 4K UltraHD, HDR, and other advanced features. Each cable bears the Premium HDMI Certification label to guarantee authenticity. The Premium Certified Cables feature a smaller overmold for easier pulling between studs or wiring through articulating mounts. The enhanced retention clips on the connector head keep the cable firmly in place and require 4.5lbs of pulling force to remove. This ensures the most secure connection points, maximizing signal integrity and reducing cable-related service calls.
