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. » 54 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (24.8 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. » 37 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (39.5 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, 51 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 9331 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

En tant que convertible de 17 pouces, le Dell Inspiron 17 7786 continue à être sans rivaux, si l’on met de côté son prédécesseur immédiat. Avec ce nouveau convertible géant, Dell reste dans la lignée du prédécesseur, le Dell Inspiron 17 7773. Au premier abord, le nouveau 2-en-1 ne paraît pas très différent, les changements de design n’apparaissant que quand on y regarde de plus près. On peut toujours débattre de leur discrétion, mais les changements les plus importants sont ceux faits à l’intérieur de la machine, le processeur Kaby Lake ayant été remplacé par le nouvel Intel Core i7-8565U (Whiskey Lake). Il propose une fréquence de Boost bien plus élevée, et devrait donc être plus performant. Mais durant nos tests, ce boost n’a malheureusement pas pu être maintenu, et son prédécesseur l’a même battu dans notre boucle Cinebench R15 Multi… Le processeur nous a malgré tout à peu près satisfaits, au final.

Malheureusement, Dell ne propose cet appareil que dans cette configuration CPU / GPU. Nous ne comprenons pas trop pourquoi il n’est pas proposé avec un processeur Whiskey Lake i5. Les clients n’ont le choix que du stockage. Nous recommandons de choisir une combinaison SSD et disque dur, telle que sur notre machine. Avec 16 Go de RAM et l’écran tactile de 17 pouces, les clients doivent dépenser 1 328 €.

Tous ceux qui hésitent entre un convertible ou un appareil multimédia devraient opter pour le Dell Inspiron 17 7786. Ce portable de 17 pouces combine ces deux utilisations, et sa carte graphique permet même de jouer un peu.

Le Dell Inspiron 17 7786 a pu nous convaincre avec de très bons matériaux et une base robuste. Les périphériques d’entrée sont bons, même si certains petits détails empêchent l’appareil d’avoir une meilleure note. L’expérience de frappe est meilleure qu’avec le prédécesseur, et la course des touches a également été ajustée.

Par rapport à son prédécesseur, l’écran est légèrement plus lumineux et plus réactif, mais ses couleurs sont moins fidèles. À cause de la surface très sujette aux reflets, la luminosité supérieure ne change rien pour l’utilisation de l’appareil à l’extérieur.

Le Dell Inspiron 17 7786 est ainsi une mise à jour réussie de son prédécesseur, avec une consommation améliorée, et une autonomie bien plus élevée.
