Test du LG Gram 14T90N (i7-10510U, UHD 620, FHD) : un processeur à la baisse

Performances insuffisantes au vu du prix. Le dernier LG Gram 14 2-en-1 est la mise à jour du modèle Whiskey Lake U de l’an dernier. Malheureusement le nouveau modèle n’a pas vraiment les arguments pour passer de l’ancienne version à la nouvelle.

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
32.8 ms ... hausse ↗ et chute ↘ combinées↗ 19.6 ms hausse
↘ 13.2 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. » 84 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (24.8 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. » 88 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (39.4 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, 51 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 18254 (minimum : 5 - maximum : 2500000) Hz dans le cas où une MDI était active.

En test : le LG Gram 14T90N.
En test : le LG Gram 14T90N.

La différence entre l’ancien LG Gram14T990 et le nouveau LG Gram 14TN90N est minimale. Le passage à un nouveau processeur est à peine visible, ce qui fait du nouveau port Thunderbolt 3 la seule différence notable entre les deux modèles. Ceux qui utiliseraient ce port, par exemple pour une station d’accueil ou un écran externe, pourront être séduits par le Gram 14T90N. Les autres pourront économiser quelques centaines d’euros, et conserver ou choisir le Gram 14T990.

Le convertible LG possède néanmoins quelques avantages sur la concurrence. Son poids plume le rend plus facile à utiliser en mode tablette que le ZenBook 14 Flip par exemple, et les deux emplacements de stockage sont une rareté vu la catégorie de la machine. Mais même avec ces arguments, le système semble sous-équipé pour son prix, surtout en ce qui concerne les graphismes, tandis que des fonctionnalités comme un cache de webcam ou une webcam infrarouge sont tout simplement absentes. Un processeur Core i7 Ice lake aurait peut-être fait mieux les choses, vu l’audience-cible de la machine. L’écran aurait également pu être plus lumineux, pour rendre la lecture à l’extérieur plus confortable.

Le Gram 14T90N est un convertible à 1 400 € avec un processeur bridé et rien pour se démarquer. Il faudra exploiter poids, son autonomie et son port Thunderbolt 3 pour en tirer profit…

L’intégralité de cette critique est disponible en anglais en suivant LG Gram 14T90N.
