Courte critique du convertible Dell Inspiron 7390 2-en-1 Black Edition (i7-8565U, UHD 620, 4K UHD HDR)

Steve Schardein, 👁 Allen Ngo (traduit par Prévots), 09/02/2019

Deuxième version. L’Inspiron 7390 2-en-1 ressemble peut-être à son prédécesseur, mais beaucoup de choses ont changé à l’intérieur. Pour 1250 $, le convertible intègre un écran UHD, un Core i7-8565U, 16 Go de RAM, et un SSD NVMe de 512 Go. Est-ce la dernière référence en date des convertibles ?

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
37.6 ms ... hausse ↗ et chute ↘ combinées↗ 20.4 ms hausse
↘ 17.2 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. » 94 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (24.9 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%

↘ 28.8 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. » 92 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (39.6 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 9266 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

En test : le Dell Inspiron 7390 2-en-1 Black Edition.

Le Dell Inspiron 7390 2-en-1 Black Edition à 1 249 € (tel que configuré ici) ressemble à son prédécesseur, mais il corrige un certain nombre de défauts de l’Inspiron 7386 2-en-1. En premier lieu, la consommation au ralenti, qui a baissé de presque la moitié, et l’autonomie, de 40 % supérieure. Nous n’avons pas non plus détecté de coil whine, et l’écran est un peu plus lumineux qu’avant. Mêmes les performances du processeur sont un cran au-dessus, bien que les deux machines soient équipées de la même puce.

En plus de cela, l’écran UHD est réussi, avec des couleurs fidèles et un bon calibrage en sortie d’usine, et le bouton de démarrage revu (avec lecteur d’empreintes digitales intégré) et l’organisation du clavier fonctionnent bien. La construction et le design du châssis sont bons pour cette classe, et celui-ci semble même un peu plus rigide que certains concurrents en métal. Enfin, la conception intelligente de la charnière, qui intègre une cavité magnétique pour le stylet Dell, est l’une des meilleures solutions de stockage jamais vue pour un stylet grand format.

L’Inspiron 7390 2-en-1 fait mieux que son prédécesseur dans un grand nombre de domaines – plus particulièrement en ce qui concerne l’autonomie et les performances. Malgré quelques critiques concernant les périphériques d’entrée et la pertinence du CPU Core i7, il s’avère être une alternative crédible aux concurrent Lenovo ou HP.

Cependant certains défauts sont toujours présents. Les performances restent décevantes face à celles de concurrents comme le ThinkBook 13s de Lenovo, dans cTDP Up. La sélection des ports est réduite, et l’absence de Thunderbolt 3 et de verrou Kensington en gênera certains. De même, les boutons intégrés au touchpad nécessitent trop de force pour être cliqués, et deviennent fatigants à utiliser au bout d’un moment. Enfin, si l’écran est plutôt réussi, il aurait été bien d’avoir une version FHD, qui aurait largement boosté l’autonomie – l’écran haut de gamme n’aurait sans doute pas trop manqué à beaucoup.

Parmi les concurrents qui valent le coup, on retrouve le ThinkPad X1 Yoga , le HP Envy x360 13, le ThinkPad X390 Yoga et, plus cher, le Latitude 7400 2-en-1. Mis à part les reproches concernant les périphériques d’entrée et les puces chères qui ne sont pas utilisées au mieux, l’Inspiron 2-en-1 semble maintenant être une alternative crédible aux séries Yoga et x360 convertibles, qui faisaient oublier son prédécesseur.
