\u00c9crans 120 Hz : qu'est-ce que c'est ?<\/h2>\n

\"ecranNous allons commencer par le d\u00e9but pour mieux comprendre l\u2019enjeu<\/strong>. La fr\u00e9quence de rafra\u00eechissement d\u2019un \u00e9cran se d\u00e9finie par le nombre d\u2019images qui s\u2019affiche \u00e0 chaque seconde et elle est exprim\u00e9e en Hz (hertz), plus la fr\u00e9quence est \u00e9lev\u00e9e plus c\u2019est fluide. Cela contribue \u00e0 un meilleur confort visuel pour les utilisateurs. Il faut \u00e9galement veiller \u00e0 ne pas confondre les FPS (images par seconde) et la fr\u00e9quence de rafra\u00eechissement qui n\u2019ont aucun rapport. Cette donn\u00e9e provenant de ce que la carte graphique ou la puce graphique d\u2019un SoC est capable d'afficher.<\/p>\n

Il est n\u00e9anmoins essentiel qu\u2019il y ait un \u00e9quilibre entre l\u2019\u00e9cran et la puce graphique pour jouir d\u2019une bonne exp\u00e9rience. Disposer d\u2019un \u00e9cran pouvant atteindre les 120 Hz c\u2019est bien, mais si la puce graphique est \u00e0 la tra\u00eene cela n\u2019a aucun int\u00e9r\u00eat. Est-ce qu\u2019il est facile de distinguer la diff\u00e9rence entre du 60 Hz et du 120 Hz ? Pour les habituer oui il y aura une nette diff\u00e9rence, notamment dans les jeux puisque c\u2019est surtout \u00e0 \u00e7a que se destine cette technologie. De nombreux joueurs PC ne veulent plus revenir en arri\u00e8re lorsqu\u2019ils go\u00fbtent \u00e0 une fr\u00e9quence de rafra\u00eechissement sup\u00e9rieure \u00e0 60 Hz.<\/p>\n

Sur un smartphone, on peut se demander quel int\u00e9r\u00eat il y a sur un si petit \u00e9cran de b\u00e9n\u00e9ficier d\u2019une telle fr\u00e9quence de rafra\u00eechissement. Nous allons revenir sur les usages un peu plus loin dans notre dossier. Il est certain que tout le monde n\u2019y trouvera pas forc\u00e9ment un int\u00e9r\u00eat \u00e9vident<\/strong>. Sans oublier que cela contribue \u00e0 consommer davantage de ressources sur nos petits appareils, moins d\u2019autonomie par exemple et une puce graphique qui sera davantage sollicit\u00e9e.<\/p>\n
