Recensione breve del Portatile Dell Latitude 14 7414 Rugged Extreme (6200U, HD)

Sascha Mölck (traduzione a cura di G. De Luca), 04/28/2017

Solido come una roccia. Questo robusto Dell da 14" resiste a polvere, liquidi, schizzi e calore. Non solo è bello, ma ha anche hardware potente, molte porte e una lodevole durata.

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 Hz20 % brightness setting

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

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6262 (minimum: 43 - maximum: 142900) Hz was measured.

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
27 ms ... rise ↗ and fall ↘ combined↗ 17 ms Incremento

Lo schermo mostra tempi di risposta relativamente lenti nei nostri tests e potrebbe essere troppo lento per i gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 52 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.7 ms).

Il Dell Latitude 14 7414 Rugged Extreme è un portatile da 14" per situazioni estreme. L'interno è protetto da polvere, liquidi, schizzi e calore. Rispetto al predecessore non è cambiato nulla all'esterno. I miglioramenti sono solo dentro. Haswell fa spazio alla Skylake, che migliora la potenza di calcolo dei nuovi modelli. Nonostante questo incremento di prestazioni, non si notano peggioramenti di temperature o di rumore. Il Latitude resta silenzioso e fresco tutto il tempo. Inoltre l'autonomia è molto buona.

Il Latitude 14 7414 è attrezzato per situazioni estreme.

Un solid-state drive consente un sistema scattante. Potete senza sforzi cambiare l'SSD. Già conosciamo la retroilluminazione della tastiera del predecessore. L'esperienza di digitazione è comoda. Il display resta lo stesso modello con identiche luminosità, contrasto elevato e angoli di visuale buoni che abbiamo visto sul predecessore Haswell. Dell limita un po' l'upgrade in termini di selezione delle porte. Non sono offerte nemmeno come opzione Thunderbolt 3, DisplayPort o USB Type-C.

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