Mike Wobker, 👁 Sebastian Jentsch, Felicitas Krohn (traduit par Prévots), 09/23/2019

Lecteur de DVD en option. Lenovo présente le V155 comme une plateforme productive pour professionnels. Mais un premier coup d’œil au portable montre bien que l’appareil appartient à l’entrée de gamme. Au-delà de cette impression, nos tests vont montrer les vraies performances du V155.

* ... 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
14 ms ... hausse ↗ et chute ↘ combinées↗ 10 ms hausse
↘ 4 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. » 16 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont meilleures que la moyenne (24.8 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
44 ms ... hausse ↗ et chute ↘ combinées↗ 23 ms hausse
↘ 21 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. » 65 % 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 9338 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

Verdict

En test : le Lenovo V155. Modèle de test fourni par Lenovo Allemagne.
En test : le Lenovo V155. Modèle de test fourni par Lenovo Allemagne.

Dans nos tests, le Lenovo V155 s’avère être un bon portable pour des exigences peu élevées. Son prix se reflète surtout dans son écran, et dans sa connectique. Les performances sont plus que suffisantes pour la bureautique, et le multimédia. Avec 4 Go de RAM, et 8 Go amovibles, la configuration de mémoire est assez inhabituelle, mais au moins elle s’avère suffisante. Ceux qui peuvent se passer d’un lecteur optique pourront à la place intégrer un gros disque dur.

Le Lenovo V155 est très abordable, et possède de bonnes performances avec son processeur AMD. Cependant son autonomie et son écran pourraient être meilleurs.

Par ailleurs, les périphériques d’entrée sont bons, et le WLAN moyen. Alors que l’autonomie aurait pu être meilleure, on peut quand même tenir quelques heures sans chargeur – il faut ici se souvenir du prix d’environ 500 €, pour lequel le Lenovo V155 propose des performances plutôt bonnes.
