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
30.4 ms ... rise ↗ and fall ↘ combined↗ 15.6 ms Incremento
↘ 14.8 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 0.8 (minimum) to 240 (maximum) ms. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.7 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
44 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms Incremento
↘ 24.4 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. » 63 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.8 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 922.1 Hz20 % brightness setting

The display backlight flickers at 922.1 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 922.1 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

Dell Latitude 7285, fornito da Dell Germany
Dell Latitude 7285, fornito da Dell Germany

Con il Dell Latitude 7285, il produttore presenta un convertibile davvero high-quality con componenti moderni. L'Intel Core i5-7Y57 offre solide performance e va bene per le applicazioni quotidiane da ufficio. La CPU gestisce anche le applicazioni multimedia. Spesso il frugale SoC regge bene il confronto con i processori ULV più veloci. Per 2.300 Euro (~$2740) questo dispositivo per quello che vi dà non e molto economico. Tuttavia, riceverete un dispositivo ben costruito, con una ottima impressione sulla sua qualità da ogni punto di vista.

Il prezzo potrebbe impaurire qualcuno a primo impatto, ma Dell offre un dispositivo ben costruito con uno schermo 3K di prima classe e una selezione di connessioni moderne. Oltre al tablet ed alla keyboard dock, la confezione include la Dell Active Pen e 36 mesi di garanzia.

Abbiamo apprezzato la selezione di buoni materiali e il design sobrio. Il Dell Latitude 7285 riceve un'ottima valutazione per il display, che ha una luminosità molto elevata e una buona copertura della gamma di colore. Francamente, ci saremmo aspettati meno prestazioni dal processore, ma poiché Dell un lo limita con il TPD da 4,5 watts, le performance sono leggermente sopra le nostre attese. Tutti i risultati dei test senza eccezione mostrano che il Dell Latitude 7285 basato sull'Intel Core i5-7Y57 regge bene il confronto con la concorrenza.

Per quanto riguarda i consumi, il dispositivo ci ha deluso un po', in quanto ci saremmo aspettati valori migliori da componenti frugali. Questo si nota anche nei risultati misti dell'autonomia della batteria. L'idea di mettere una batteria aggiuntiva nella keyboard dock è buona e previene un piazzamento peggiore nel nostro test di confronto.

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