La Video Electronics Standards Association (VESA) a annonc\u00e9 aujourd'hui la sortie de la norme DisplayPort 2.1. Heureusement pour les consommateurs, il ne faudra vraisemblablement pas acheter de nouveaux c\u00e2bles pour en profiter.<\/strong><\/p>\n

\"Displayport<\/p>\n

La nouvelle norme DisplayPort 2.1 apporte quelques am\u00e9liorations par rapport \u00e0 la norme DisplayPort 2.0. On peut notamment citer une conformit\u00e9 plus stricte avec les sp\u00e9cifications PHY de l'USB Type-C et de l'USB4 ainsi qu\u2019une meilleure connectivit\u00e9 gr\u00e2ce au tunneling DisplayPort sur l'USB4.<\/strong> Une int\u00e9gration plus \u00e9troite entre l'USB4 et le DisplayPort devrait faciliter le d\u00e9veloppement et l'adoption de ces technologies. D\u2019ailleurs, une nouvelle norme USB4 Version 2.0 a \u00e9galement r\u00e9cemment vu le jour<\/a>.<\/p>\n

La nouvelle norme DisplayPort 2.1 va \u00e9galement permettre d\u2019avoir des c\u00e2bles beaucoup plus longs tout en maintenant un d\u00e9bit \u00e9lev\u00e9.<\/strong> Les c\u00e2bles certifi\u00e9s pour le DP40 (supportant le taux de liaison UHBR10 et jusqu'\u00e0 40 Gbps de bande passante au total) peuvent d\u00e9sormais d\u00e9passer deux m\u00e8tres de long<\/strong>, tandis que les c\u00e2bles certifi\u00e9s pour le DP80 (supportant UHBR20 et 80 Gbps de bande passante) peuvent d\u00e9passer un m\u00e8tre de long. Vous ne devriez donc pas subir de d\u00e9gradation du signal avec des c\u00e2bles aussi longs, \u00e0 condition qu'ils soient correctement certifi\u00e9s.<\/p>\n
