As 4K resolution/UltraHD video-signal becomes the new standard for both home cinemas and the professional film industry, the quality of such a seemingly secondary part of the system as connecting cables is becoming crucially important. Even minor losses become obvious when dealing with ultra HD resolution pictures and a greater dynamic range of luminosity HDR/Dolby Vision.
Copper
Oxygen-free copper (OFC) is a high conductivity copper alloy that has been electrolytically refined to reduce the level of oxygen to .001% or below which affects its crystal structure
and the accuracy of phase transmission of the signals. Used as the main conductor
in Little Lab Lake HDMI cables.Silver
Silver plating offers excellent electrical conductivity and reduces heat, which is crucial for carrying high frequency signals. 5% and 10% Silver Plated Copper conductors are used in Little Lab Sea and Ocean HDMI cables.
