Le Vivo Xplay 3S, premier smartphone avec \u00e9cran 2K<\/figcaption><\/figure>\n

 <\/p>\n

Quels contenus vid\u00e9o sont diffus\u00e9s en Ultra HD ?<\/h2>\n

Comme nous l'avons vu plus haut, le Blu-Ray s\u2019appr\u00eate \u00e0 passer \u00e0 la d\u00e9finition Ulta HD. La plupart des films \u00e0 gros budget sont d'ailleurs d\u00e9j\u00e0 tourn\u00e9s en 4K, preuve que le contenu original existe d\u00e9j\u00e0 pour les films. Les principales limites viennent encore des capacit\u00e9s de stockage<\/strong>, mais aussi au niveau de la connectique qui prendra en charge le rafra\u00eechissement 60 Hz en 2160p (la norme \u00ab\u00a0HDMI 2.0\u00a0\u00bb s\u00fbrement).<\/p>\n

Actuellement, le HDMI 1.4 permet une diffusion de cette r\u00e9solution, mais limit\u00e9e \u00e0 30 images par seconde. Concernant le stockage, seuls les disques durs sont pour l'instant \u00e0 m\u00eame d'accueillir des contenus 4K tr\u00e8s volumineux.<\/p>\n
