Temps de réponse de l'écran

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
27 ms ... hausse ↗ et chute ↘ combinées↗ 16 ms hausse
↘ 11 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. » 53 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (25.6 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
38 ms ... hausse ↗ et chute ↘ combinées↗ 19 ms hausse
↘ 19 ms chute
L'écran souffre de latences très élevées, à éviter pour le jeu.
En comparaison, tous les appareils testés affichent entre 0.9 (minimum) et 636 (maximum) ms. » 34 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (41 ms) de tous les appareils testés.

Scintillement / MLI (Modulation de largeur d'impulsion)

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 9265 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.
