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
20 ms ... rise ↗ and fall ↘ combined↗ 9.2 ms Incremento
↘ 10.8 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. » 12 % 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
39.2 ms ... rise ↗ and fall ↘ combined↗ 20.4 ms Incremento
↘ 18.8 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. » 41 % of all devices are better.
This means that the measured response time is similar to 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 211.9 Hz20 % brightness setting

The display backlight flickers at 211.9 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 211.9 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

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.

Recensione: Fujitsu LifeBook U937. Modello fornito da Fujitsu

Ci è piaciuto il Fujitsu LifeBook U937. A parte il touchpad scarso e l'assenza di illuminazione della tastiera, i pochi punti di critica sono poca cosa e non hanno un grosso impatto sulle prestazioni complessive, questo piccolo compagno business non ha dei grossi punti deboli.

Sì, il display potrebbe avere una migliore distribuzione della luminosità e la rumorosità della ventola di raffreddamento potrebbe dare fastidio agli utenti sensibili. Ma l'SSD SATA III può essere sostituito con una versione PCIe e le piccole ventole di raffreddamento fanno lo stesso rumore della maggioranza di dispositivi simili.

D'altro canto, ci sono molti aspetti positivi in questo dispositivo: innanzitutto, il peso incredibile di appena 950 gr (~2.1 lb) e le sue dimensioni compatte. Inoltre ha molte funzioni di sicurezza ed un'autonomia molto buona. Un altro punto di forza e la facilità di manutenzione e di espansione. Il dispositivo è particolarmente adatto come portatile aziendale (smart card), ma va bene anche per gli utenti privati.

Per poco meno di $1500, avrete un portatile molto piccolo e forse tra i più leggeri business con molte features di sicurezza, una buona autonomia e un display luminoso. Possiamo sicuramente raccomandare l'U937. Ha solo qualche piccola pecca e ma per molti aspetti è brillante.

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