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 65000 Hz ≤ 10 Niveau de luminosité

Le rétroéclairage de l'écran scintille à la fréquence de 65000 Hz (certainement du fait de l'utilisation d'une MDI - Modulation de largeur d'impulsion) à un niveau de luminosité inférieur ou égal à 10 % . Aucun scintillement ne devrait être perceptible au-dessus de cette valeur.

La fréquence de rafraîchissement de 65000 Hz est élevée, la grande majorité des utilisateurs ne devrait pas percevoir de scintillements et être sujette à une fatigue oculaire accrue.

En comparaison, 54 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 8895 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

En test : le Lenovo IdeaPad 720s-13ARR 81BR000XGE. Modèle de test aimablement fourni par Lenovo Allemagne.

Le Lenovo IdeaPad 720s-13ARR est un appareil solide, mais son système de refroidissement défaillant et ses réglages d’enveloppe thermique l’empêchent d’exploiter tout le potentiel de son APU et de son GPU. Pire, Lenovo a limité l’appareil au mode monocanal, bridant ainsi les performances de la carte graphique - ce qui ne peut être corrigé. Les performances sont suffisantes pour la bureautique et Internet, mais les performances CPU et GPU pourraient être bien meilleures que ce qu’elles sont.

Le Lenovo IdeaPad 720s-13ARR ne parvient pas à tirer profit de son APU Ryzen 7 2700U, dans la mesure où il n’est pas plus performant que ses homologues moins chers.

Point positif malgré tout, le SSD est rapide et permet au système d’être réactif. De même, le rétroéclairage du clavier est réussi, et l’écran Full HD est lumineux et bien contrasté. Malheureusement l’autonomie est moyenne.

Cela dit, nous recommandons de choisir le 720s-13IKB plus cher, plutôt que le 720s-13ARR : il possède un processeur Core Intel, qui est plus équilibré que l’APU AMD. Il possède de plus un port Thunderbolt 3, tandis que le modèle Ryzen ne possède qu’un port USB C. Le 720s-13IKB possède également une meilleure autonomie malgré sa batterie plus petite. Dans l’ensemble, le 720s-13ARR ne peut concurrencer ses homologues Intel au niveau du prix.
