Courte critique du Lenovo ThinkPad T590 (i7-8565U, MX250, FHD) : PC portable grand et léger, mais écran à la traîne

Benjamin Herzig, 👁 Andreas Osthoff (traduit par Prévots), 08/05/2019

Coulé par l'écran. Le Lenovo ThinkPad T590 est une plus grosse version du populaire ThinkPad T490. Le châssis plus grand offre certains avantages, et le ThinkPad T590 est le ThinkPad de 15,6 pouces le plus léger de la série T. Malheureusement, il fait moins bien que ses petits frères dans un domaine critique…

* ... Moindre est la valeur, meilleures sont les performances

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
27.2 ms ... hausse ↗ et chute ↘ combinées↗ 17.2 ms hausse
↘ 10 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. » 56 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (25.1 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
37.2 ms ... hausse ↗ et chute ↘ combinées↗ 19.2 ms hausse
↘ 18 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. » 34 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (40 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 9457 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

En test : le Lenovo ThinkPad T590. Modèle de test fourni par

Le Lenovo ThinkPad T590 est le ThinkPad de 15,6 pouces le plus léger et le plus compact de la série T. Par le passé, on était obligé de choisir les modèles plus compacts de 14 pouces pour éviter d’avoir un portable extrêmement épais et lourd. Ce n’est plus le cas aujourd’hui. Le Lenovo ThinkPad T490 reste cependant sans doute le meilleur choix pour la plupart des utilisateurs.

Un des points importants qui explique cela est que le T490 et le T590 sont très proches, dans bien des domaines. Lenovo utilise la même conception de carte-mère pour les deux, et leurs matériaux et leur construction sont identiques. Le Lenovo ThinkPad T590 possède un châssis robuste avec une connectivité et des options de sécurité abondantes, mais le ThinkPad T490 également. Il en va de même pour les périphériques d’entrée très confortables avec l’excellent clavier, même si le T590 a l’avantage dans ce domaine avec son pavé numérique. De même, l’autonomie du ThinkPad T590 est meilleure que celle du T490, au moins en version FHD, grâce à la plus grosse batterie, de 57 Wh. Le ThinkPad T590 propose des performances processeur au-dessus de la moyenne, et son ventilateur n’est pas trop bruyant – mais c’est pareil avec le T490.

Le plus grand écran peut être considéré comme un avantage pour le ThinkPad T590. Cependant, la qualité de la dalle LCD est horrible comparée à celle du T490, et son écran FHD Low Power. La gamme de couleurs et la luminosité de l’écran sont bien pires. En option, Lenovo propose une dalle 4K UHD, mais la grande majorité des T590 sera probablement équipée de l’écran FHD. D’autres points faibles, comme la difficulté à ouvrir le châssis, le lecteur de carte micro SD et non SD grand format, les températures élevées du châssis et le port Thunderbolt 3, qui n’est connecté que grâce à deux voies PCIe, sont les mêmes qu’avec le ThinkPad T490. Il en va de même pour la fonctionnalité PowerBridge abandonnée.

Si seulement l’écran était meilleur : le ThinkPad T590 est un bon portable, mais la dalle LCD gâche tout.

Tout compte fait, nous pouvons toujours recommander le ThinkPad T590, comme étant un portable de 15,6 pouces relativement nomade avec d’excellentes performances pour les tâches professionnelles. Nous pensons néanmoins que le ThinkPad T490 est meilleur, surtout pour ceux qui n’ont pas besoin de pavé numérique. Par rapport aux autres portables de 15,6 pouces de la même classe, tel le HP EliteBook 850 G5, le ThinkPad possède de meilleurs périphériques d’entrée, et de meilleures performances CPU, mais un moins bon écran – à moins de choisir la version 4K UHD.
