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
24.4 ms ... hausse ↗ et chute ↘ combinées↗ 12.8 ms hausse
↘ 11.6 ms chute
L'écran montre de bons temps de réponse, mais insuffisant pour du jeu compétitif.
En comparaison, tous les appareils testés affichent entre 0.8 (minimum) et 240 (maximum) ms. » 38 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (25.7 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
39.2 ms ... hausse ↗ et chute ↘ combinées↗ 20.4 ms hausse
↘ 18.8 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. » 42 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (41.1 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, 53 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 8811 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

Le Fujitsu LifeBook U748 est un portable pro robuste, tout comme son prédécesseur. La mise à niveau du CPU améliore les performances, au prix d’une baisse de l’autonomie, l’appareil consommant plus. Dans l’ensemble, le LifeBook U748 est un appareil impressionnant avec un bon écran tactile et un clavier honnête, agréable à utiliser. Les nuisances sonores restent mesurées, même si elles peuvent parfois s’avérer gênantes, et les haut-parleurs et la webcam sont très moyens – comme c’est souvent le cas sur les portables pros.

Le Fujitsu LifeBook U748 séduit grâce à son bon écran, son SSD rapide, et ses fonctionnalités de sécurité nombreuses, nécessaires pour un portable professionnel. Malheureusement le mauvais et obsolète touchpad reste inchangé.

Fujitsu équipe le LifeBook U748 avec le même touchpad inachevé que son prédécesseur. En revanche, le design fin et le châssis robuste nous ont plu, avec leur aspect premium. Une bonne sélection de ports complète l’ensemble, même si l’absence de Thunderbolt se fait remarquer.

Nous donnons au Fujitsu LifeBook U748 une recommandation d’achat, puisqu’il s’agit dans l’ensemble d’un bon appareil. La concurrence continue cependant de s’améliorer, et le LifeBook aura peut-être du mal à suivre le Lenovo ThinkPad T480s.
