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, 52 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 15315 (minimum : 5 - maximum : 2500000) Hz dans le cas où une MDI était active.

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
25.6 ms ... hausse ↗ et chute ↘ combinées↗ 12.4 ms hausse
↘ 13.2 ms chute

Xiaomi met en avant son smartphone abordable du milieu de gamme par ces mots : "tout ce dont vous avez besoin". Le fabricant chinois de Shenzhen n'a pas tout à fait tort, le Redmi Note 9 fournissant une très bonne expérience à un prix d'environ 150 € - mais nous recommandons d'investir les 20 € supplémentaires pour la version 4 Go.

Ceux qui cherchent un smartphone abordable à moins de 200 € doivent absolument prendre en compte le Redmi Note 9.

Par rapport au Redmi 9, la version Note possède un meilleur haut-parleur et un meilleur appareil photo principal. L'écran IPS plus lumineux est plus contrasté et ses angles de vision sont plus larges, lui donnant l'avantage au quotidien. Et le Note 9 inclut un chargeur rapide par défaut.

Cependant, le Redmi Note 9 reste un smartphone d'entrée de gamme. De ce fait, il faut faire des compromis dans le choix du processeur, de la qualité des photos - surtout en ultra-grand-angle - et des vitesses du stockage et du WLAN.
