Temps de réponse de l'écran

ℹ

Le temps de réponse d'un écran mesure la rapidité à laquelle l'écran est capable de changer une couleur pour une autre. Un temps de réponse élevé se traduit par une image floutée pour les objets en mouvement. Les joueurs bénéficieront de faibles latences d'affichage en jeu.

↔ Temps de réponse noir à blanc
28 ms ... hausse ↗ et chute ↘ combinées	↗ 14 ms hausse
28 ms ... hausse ↗ et chute ↘ combinées	↘ 14 ms chute
L'écran souffre de latences relativement élevées, insuffisant pour le jeu. En comparaison, tous les appareils testés affichent entre 0.8 (minimum) et 240 (maximum) ms. » 60 % des appareils testés affichent de meilleures performances. Cela signifie que les latences relevées sont moins bonnes que la moyenne (24 ms) de tous les appareils testés.
↔ Temps de réponse gris 50% à gris 80%

55 ms ... hausse ↗ et chute ↘ combinées	↘ 28 ms chute
L'écran souffre de latences très élevées, à éviter pour le jeu. En comparaison, tous les appareils testés affichent entre 0.8 (minimum) et 636 (maximum) ms. » 89 % des appareils testés affichent de meilleures performances. Cela signifie que les latences relevées sont moins bonnes que la moyenne (38.1 ms) de tous les appareils testés.

Scintillement / MLI (Modulation de largeur d'impulsion)

ℹ

Afin d'abaisser la luminosité de l'écran, certains ordinateurs portables font varier très rapidement le rétroéclairage entre éteint et allumé. La fréquence à laquelle le rétroéclairage s'éteint et se rallume est normalement fixée à une valeur qui permet de rendre la variation indétectable à l'œil nu? Si la fréquence est trop basse, certaines personnes peuvent être sujettes à une fatigue oculaire, des maux de tête ou même percevoir les variations.

Scintillement / MLI (Modulation de largeur d'impulsion) non décelé

En comparaison, 52 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 14804 (minimum : 5 - maximum : 2500000) Hz dans le cas où une MDI était active.

Verdict

En test : l'Asus ExpertBook B9450FA. Modèle de test fourni par Asus Allemagne.

Notre test de l'Asus ExpertBook B9450FA révèle nombre de points forts. L'ultraportable est très léger et très nomade, grâce à son autonomie exceptionnelle. Son écran est assez lumineux, et ses couleurs sont bonnes, tandis que ses performances sont celles d'une machine de ce type. Et un cache manuel de webcam ainsi qu'un pavé numérique intégré dans le touchpad complètent l'offre.

L'ExpertBook B9 d'Asus est un PC portable ultraléger de très haute qualité avec une excellente autonomie.

Mais nous avons quelques critiques à formuler, qui pourraient être décisives pour certains. Asus a choisi de ne pas inclure de lecteur de carte SD, et nous aurions espéré la 4G sur un appareil aussi nomade. Le fait que le module de RAM soit soudé n'est pas non plus génial - tout en se justifiant, vu la finesse de l'ultrabook. Au moins deux emplacements SSD sont disponibles, et faciles à accéder parce que la coque inférieure est aisée à retirer.
