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
14 ms ... rise ↗ and fall ↘ combined↗ 8 ms Incremento
↘ 6 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. » 8 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.6 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
44 ms ... rise ↗ and fall ↘ combined↗ 22 ms Incremento
↘ 22 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. » 62 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.7 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 200 Hz90 % brightness setting

The display backlight flickers at 200 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 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 56 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 7817 (minimum: 43 - maximum: 142900) Hz was measured.

Lenovo Thinkpad E470. Modello fornito da Lenovo.

La sintesi è che l'E470 è un economico portatile business ma non possiamo raccomandare questa versione oggi.

Ha molti vantaggi dell'altro E470: dispositivi di input comodi e decenti con la leggendaria tastiera ThinkPad ed il track point; un case solido e ben costruito che sicuramente non è bello, ma fa il suo dovere; un veloce modem Wi-Fi; e solide prestazioni con le applicazioni - tutto quello che vi potete aspettare dall'E470. L'unico aspetto in cui l'attuale modello supera il precedente con 940MX riguarda sistema di raffreddamento ed autonomia. L'assenza della GPU Nvidia rende il portatile meno caldo e più silenzioso, e la bassa risoluzione del display consente una autonomia migliore.

Ma è l'unico vantaggio del display HD. Per il resto il display è pessimo: valore del nero troppo alto, angoli vi visuale miseri, e gamma di colore non degna del suo nome. Inoltre, usa il PWM per la modulazione della luminosità a frequenze molto basse.

Non possiamo raccomandare questo modello di E470 a causa della configurazione sbilanciata e del pessimo display. Se siete interessati all'E470 assicuratevi che ci sia un display IPS.

Questo basta a negare la raccomandazione all'E470. Quasi 800 sono troppi per un portatile con un display scarso come questo. Se volete l'E470 assicuratevi che ci sia un display FHD IPS. Altrimenti l'E470 è davvero molto lontano dalla perfezione. Parliamo anche dell'assenza di una porta USB-C, e la garanzia Lenovo standard di appena 12 mesi. Potremmo convivere con queste pecche pensando al prezzo basso ma il display è un punto fondamentale. Inoltre il dispositivo non sfrutta tutta la potenza quando si usa la batteria, il che peggiora ancora il punteggio finale.

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