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
29 ms ... hausse ↗ et chute ↘ combinées↗ 17 ms hausse
↘ 12 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. » 68 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (25.9 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
41 ms ... hausse ↗ et chute ↘ combinées↗ 19 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. » 49 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (41.4 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, 54 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 8895 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

Le Dell Inspiron 15 5579 est un convertible de 15,6 pouces avec très peu d’évolutions par rapport à son prédécesseur - il ressemble même au modèle d’encore avant, l’Inspiron 15 5568. Mais il est plus puissant que jamais grâce à l’Intel Core i5-8250U, et ses performances Wifi ont été largement améliorées et sont bien meilleures que sur le Dell Inspiron 15 5578 de l’an dernier. Avec 8 Go de RAM DDR4 et un SSD de 256 Go, le 5579 est vendu 749$.

Le prix paraît honnête pour ce convertible de 15,6 pouces, et les périphériques d’entrée honnêtes satisferont ceux qui rédigent beaucoup. Les points faibles de l’appareil sont son écran sombre et l’absence de compatibilité pour stylet actif.

Malheureusement, toutes les fonctionnalités modernes comme l’USB C ou le DisplayPort sont absentes. Il y a un lecteur de carte SD, mais connecté via USB 2.0. Nous apprécions le fonctionnement silencieux de l’appareil, et son autonomie acceptable. La webcam infrarouge intégrée est un petit plus pratique, qui permet de se connecter plus rapidement à Windows.

Mais l’écran est plus mitigé. Il possède un contraste très élevé et ne fait pas appel à la MLI, mais son espace colorimétrique est très limité, et sa luminosité bien trop basse.
