Test du Dynabook Portégé A30-E (i7-8550U, UHD 620, FHD) : excellent écran, châssis fragile

Sascha Mölck, 👁 Sebastian Jentsch, Felicitas Krohn (traduit par Prévots), 11/07/2019

Tout est nouveau. Le portable pro Dynabook de 13,3 pouces séduit avec un écran IPS lumineux et contrasté, un SSD NVMe et une bonne autonomie. Mais son châssis devrait être plus robuste.

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
36 ms ... hausse ↗ et chute ↘ combinées↗ 18 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 0.8 (minimum) et 240 (maximum) ms. » 92 % 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.

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 (39.5 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 250 Hz ≤ 20 Niveau de luminosité

Le rétroéclairage de l'écran scintille à la fréquence de 250 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 250 Hz est relativement faible, les personnes les plus sensibles devraient percevoir un scintillement et être sujettes à une fatigue oculaire accrue (avec le niveau de luminosité indiqué)

En comparaison, 51 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 9276 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

Le gros point fort du Portégé A30-E est son écran. C’est un écran IPS lumineux, contrasté, aux angles de vision stables, et qui possède des couleurs fidèles. La couverture de l’espace sRVB monte à 96 %.

Le Portégé A30-E laisse une impression mitigée.

La coque en plastique mat noir est ainsi bien incapable de convaincre, étant peu rigide. Le clavier rétroéclairé pourra faire l’affaire, mais pas pour ceux qui rédigent beaucoup. À l’inverse, l’autonomie est digne de louanges.

Le SSD NVMe permet au système d’être réactif. Son remplacement est possible, mais non sans efforts : la carte-mère doit être enlevée.

Le processeur Kaby Lake quadricoeur embarqué est assez puissant pour une utilisation bureautique et web. Mais il ne peut pas vraiment utiliser son Turbo Boost en cas de sollicitations multithread prolongées. Sur batterie, le turbo du CPU est peu, voire pas du tout, utilisé.

Un modem LTE permet de connecter l’appareil à Internet. Le port USB C intégré (USB 3.2 Gen. 2) intègre à la fois le DisplayPort et le Power Delivery 3.0 - qui permet d’alimenter le portable via son port USB C.
