Les signaux vid\u00e9os 4K sont extr\u00eamement gourmands en bande passante. La qualit\u00e9 des c\u00e2bles HDMI doit donc \u00eatre irr\u00e9prochable afin que le signal atteigne l’afficheur sans aucune perte. Mais on sait que plus la longueur augmente, plus le cordon doit \u00eatre de qualit\u00e9, jusqu’\u00e0 atteindre les limites physiques du HDMI.<\/p>\n
