Tempi di risposta del Display

I tempi di risposta del display mostrano quanto sia veloce lo schermo a cambaire da un colore all'altro. Tempi di risposta lenti poccono creare sovrapposizioni negloi oggetti in movimento. Specialmente i giocatori patiti del 3D dovrebbero usare uno schermo con rempi di risposta bassi.
       Tempi di risposta dal Nero al Bianco
24 ms ... rise ↗ and fall ↘ combined↗ 13 ms Incremento
↘ 11 ms Calo
Lo schermo mostra buoni tempi di risposta durante i nostri tests, ma potrebbe essere troppo lento per i gamers competitivi.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 27 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.8 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
32 ms ... rise ↗ and fall ↘ combined↗ 14 ms Incremento
↘ 18 ms Calo
Lo schermo mostra tempi di risposta lenti nei nostri tests e sarà insoddisfacente per i gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 17 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (43 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 19000 Hz90 % brightness setting

The display backlight flickers at 19000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 19000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5885 (minimum: 43 - maximum: 142900) Hz was measured.

Il Lenovo IdeaPad Miix 320 è un convertibile da 10". Il processore quad-core processor e 4 GB di memoria di lavoro sono sufficienti per il tipo di attività per cui è pensato. Ma dovrete ricordare che per 459 Euro (~$350) non potrete avere un dispositivo premium. L'SSD da 128 GB è abbastanza grande, e sono disponibili versioni più piccole. Ma noi raccomandiamo la versione da 128 GB.

Il Lenovo IdeaPad Miix 320 dà l'impressione di essere high-quality nonostante il prezzo contenuto. Grazie alla buona scelta di materiali, il portatile appare impeccabile. La tastiera lo trasforma in pochi secondi in un portatile.

Il convertibile deve accettare qualche critica per lo schermo. Non convince per la luminosità di appena 244 cd/m². Inoltre la superficie molto riflettente rende impossibile usarlo all'aperto. La connessione instabile tra tablet e keyboard dock non corrisponde alla buona impressione iniziale, guardando da vicino. Il produttore dovrebbe rivedere questi punti per migliorare la qualità complessiva.

I dispositivi di input del Lenovo IdeaPad Miix 320 lasciano impressioni miste. La tastiera è piacevole da usare ma manca la retroilluminazione.

Nota: si tratta di una recensione breve, con alcune sezioni non tradotte, per la versione integrale in inglese guardate qui.
