Courte critique du convertible Lenovo Yoga 720 12 (i5-7200U, 128 GB)

Polyvalent mais autonomie limitée. Le nouveau compact de Lenovo possède un élégant châssis en aluminium et des charnières à 360°, mais peut être également utilisé comme un portable de bureau classique. Ses qualités comme l’écran et les périphériques d’entrée sont gâchées par un petit nombre d’inconvénients, et surtout par son autonomie.

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
26 ms ... hausse ↗ et chute ↘ combinées↗ 16 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. » 44 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (26.1 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
32 ms ... hausse ↗ et chute ↘ combinées↗ 15 ms hausse
↘ 17 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. » 18 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont meilleures que la moyenne (41.7 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, 54 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 10750 (minimum : 43 - maximum : 588200) Hz dans le cas où une MDI était active.

Les utilisateurs de l’élégant Lenovo Yoga 720-12IKB noteront deux défauts : le WLAN est lent, et l’autonomie ne tient pas une journée de travail. L’écran est très bon, sauf pour du travail d’image professionnel, et les mauvais résultats du SSD n’entachent pas les performances globales. Le nombre de ports limité est habituel parmi les convertibles compacts, ce qui fait que nous ne pouvons pas vraiment critiquer Lenovo à ce sujet.

La solidité du châssis n’est pas parfaite non plus, mais il est malgré tout réussi, avec un beau design et des matériaux de qualité. L’Active Pen fourni, les périphériques d’entrée corrects dont fait partie l’écran tactile, la chauffe et les nuisances sonores maîtrisées sont les autres avantages de la machine.

Le convertible compact et polyvalent Lenovo Yoga 720 12 est abordable, et répond à presque toutes les exigences d’une utilisation professionnelle mobile. Son seul vrai problème est son autonomie limitée.

Dans l’ensemble, nous pouvons recommander cet appareil.
