Courte critique du convertible Dell Inspiron 13 7386 2-en-1 Black Edition (i7-8565U, UHD 620, 4K UHD, SSD 512 Go)

Sven Kloevekorn, 👁 Sebastian Jentsch, Felicitas Krohn (traduit par Prévots), 01/25/2019

Décevant. Le nouveau convertible de Dell est une déception, au moins dans la configuration ici testée. Il est d’autant plus décevant que l’appareil avait tout le potentiel pour être un excellent portable, mais il est gâché par plusieurs gros défauts. Nous vous recommandons néanmoins de lire ce test, des versions moins chères pouvant corriger ces défauts…

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
30 ms ... hausse ↗ et chute ↘ combinées↗ 15 ms hausse
↘ 15 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 240 (maximum) ms. » 72 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (25.6 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%

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. » 93 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que 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) décelé 26000 Hz ≤ 20 Niveau de luminosité

Le rétroéclairage de l'écran scintille à la fréquence de 26000 Hz (certainement du fait de l'utilisation d'une MDI - Modulation de largeur d'impulsion) à un niveau de luminosité inférieur ou égal à 20 % . Aucun scintillement ne devrait être perceptible au-dessus de cette valeur.

La fréquence de rafraîchissement de 26000 Hz est élevée, la grande majorité des utilisateurs ne devrait pas percevoir de scintillements et être sujette à une fatigue oculaire accrue.

En comparaison, 52 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 9309 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

Le Dell Inspiron 13 7386 2-en-1 Black Edition est sur le papier un bon appareil. Il possède un processeur puissant, beaucoup de RAM, et un gros SSD. De plus, l’appareil possède une résolution plus élevée que les appareils de notre comparatif, et son châssis en aluminium est haut de gamme.

Malheureusement, tout se gâte avec nos premiers tests. Son Core i7-8565U est moins performant que le Core i5-8250U équipant les autres machines de notre comparatif, son SSD n’est pas spécialement rapide, et son écran UHD ne vaut pas les 200 $ supplémentaires demandés par Dell par rapport aux alternatives FHD. Le châssis est vite sale, conservant trop facilement les traces de doigt, et l’autonomie est horrible.

Le Dell Inspiron 13 7386 2-en-1 Black Edition a le potentiel pour être un excellent convertible, mais il est plombé par une autonomie anémique, une consommation élevée, et des performances à la traîne.

Au crédit de Dell, le 7386 possède de belles finitions, et de bons périphériques d’entrée. Les couleurs de l’écran sont fidèles, mais ne suffiront que pour du travail d’image non professionnel. Les haut-parleurs nous ont agréablement surpris, étant étonnamment bons pour un portable. Les configurations sont nombreuses, ce qui permet d’adapter la machine à vos besoins.

Gardez en tête que nos points négatifs sont pour la plupart liés à cette version spécifique de l’Inspiron, voire à ce modèle comme le bouton de clic gauche qui ne fonctionne pas. Si vous appréciez la série Inspiron 13 7000 2-en-1, alors nous recommandons de regarder plutôt le 7386 de base. Il possède un meilleur rapport qualité - prix, son processeur i5-8265U subira moins de throttling, il devrait avoir une meilleure autonomie, et son écran FHD devrait également moins consommer.
