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
12 ms ... hausse ↗ et chute ↘ combinées↗ 8 ms hausse
↘ 4 ms chute
L'écran montre de bons temps de réponse, mais insuffisant pour du jeu compétitif.
En comparaison, tous les appareils testés affichent entre 0.8 (minimum) et 240 (maximum) ms. » 7 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont meilleures que la moyenne (26.6 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
44 ms ... hausse ↗ et chute ↘ combinées↗ 22 ms hausse
↘ 22 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. » 63 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (42.7 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, 56 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 7499 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

L'Acer Aspire 3 est un bon PC portable d'entrée de gamme aux performances suffisantes pour des tâches quotidiennes simples et le multitâche. il peut même être utilisé pour de simples éditions d'images, mais il ne faut pas en espérer beaucoup trop. Nous avons apprécié la possibilité de maintenance facilitée par les capots en dessous pour l'espace de stockage et la RAM, mais il faut faire attention à retenir la batterie pour quelle ne tombe pas lorsqu'on enlève le capot, ce qui peut vite causer des dégâts au PC.

 L'Aspire 3 est un bon PC portable d'entrée de gamme, convenable pour la majorité des tâches et applications quotidiennes. 

L'Aspire est un bon prétendant pour quiconque est à la recherche d'un PC portable de 15,6 pouces abordable, disposant de performances suffisantes et d'un bon potentiel de mise à jour et/ou maintenance des composants internes. Si vous planifiez de l'utiliser beaucoup sur batterie, cela risque de vous poser problème du fait de sa faible autonomie.
