Test du Dell Latitude 7400 (i7-86650, UHD 620, FHD) : même le haut de gamme n'est pas sans défaut

Sascha Mölck, 👁 Andreas Osthoff, Felicitas Krohn (traduit par Prévots), 09/23/2019

Haut de gamme professionnel. Le portable pro de 14 pouces de Dell possède une grosse autonomie, un excellent clavier, et un SSD NVMe rapide. L’écran mat IPS aurait en revanche pu être plus lumineux. Et le ventilateur émet un sifflement aigu…

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↗ 21.2 ms hausse
↘ 16.4 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%

↘ 32.4 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. » 96 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (39.7 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, 51 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 9352 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

En test : le Dell Latitude 7400 (8N6DH). Modèle de test fourni par :

Le Dell Latitude 7400 est un peu plus compact et léger que son prédécesseur. L’appareil est plus séduisant, grâce à ses bordures d’écran étroites, et ses composants sont en conformité avec les dernières tendances de l’industrie. Son processeur quadricœur Whiskey Lake est assez performant pour la bureautique et Internet – mais tout son potentiel ne peut être atteint qu’appareil branché. Sur batterie, le processeur n’utilise quasiment pas son Turbo, voire pas du tout. C’est le prix à payer pour une bonne autonomie.

Avec le Latitude 7400, Dell propose un portable pro haut de gamme qui n’est pas sans défauts.

Le SSD NVMe permet à l’appareil d’être réactif, et il est possible de le changer, en retirant toute la coque inférieure. Un des points forts du portable est à notre avis le clavier. C’est l’un des meilleurs que nous ayons vus. Bien sûr, le rétroéclairage (à deux niveaux), est de la partie.

L’écran mat IPS marque des points avec ses angles de vision, son contraste, une fidélité des couleurs correcte en sortie d’usine, et une bonne couverture des espaces colorimétriques. Sa luminosité est correcte, mais aurait dû être supérieure pour un appareil à ce prix. L’appareil ne peut de ce fait pas trop être utilisé à l’extérieur.

Le port Thunderbolt 3 permet la connexion de stations d’accueil et / ou de cartes graphiques externes puissantes. Bien sûr, le port est compatible Power Delivery 3.0 et DisplayPort via USB C (il faut un adaptateur). Malheureusement, le ventilateur émet un sifflement gênant.
