Recensione Breve del Convertibile Dell XPS 13 9365 (7Y54, QHD+)

Sascha Mölck, Stefanie Voigt (traduzione a cura di G. De Luca), 05/28/2017

Eccellente display. Per questo conertibile da 13.3" XPS 13, Dell punta su un display QHD+, che offre una buona riproduzione del colore. Tuttavia, rispetto al modello XPS 13 FHD, lo schermo riduce notevolmente l'autonomia. Grazie all CPU a raffreddamento passivo, il computer è sempre silenzioso.

Sfarfallio dello schermo / PWM (Pulse-Width Modulation)

Per ridurre la luminosità dello schermo, alcuni portatili accendono e spengono la retroilluminazione in rapida successione - un metodo chiamato Pulse Width Modulation (PWM). Questa frequenza di ciclo a livello ideale non dovrebbe essere percepibile dall'occhi umano. Se tale frequenza è troppo bassa, gli utenti con occhi sensibili potrebbero stancarsi gli occhi o avere mal di testa o anche notare uno sfarfallio.
flickering dello schermo / PWM non rilevato

In confronto: 51 % di tutti i dispositivi testati non utilizza PWM per ridurre la luminosita' del display. Se è rilevato PWM, una media di 13573 (minimo: 43 - massimo: 2500000) Hz è stata rilevata.

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 possono creare sovrapposizioni negloi oggetti in movimento. Specialmente i giocatori patiti del 3D dovrebbero usare uno schermo con tempi di risposta bassi.

In confronto, tutti i dispositivi di test variano da 0.8 (minimo) a 240 (massimo) ms. » 59 % di tutti i dispositivi è migliore.
Questo significa che i tempi di risposta rilevati sono peggiori rispetto alla media di tutti i dispositivi testati (24.9 ms).

The Dell XPS 13 model that we are testing has a Core i5-7Y54 processor on board. This is in no way inferior to the nominally stronger Core-i7 processor that is built into the sibling model that we have already tested. Since both CPUs hardly reach their maximum speeds due to the passive cooling, their results in the CPU tests are to a large extent at the same level. Only a slight advantage that can hardly be noticed during everyday operation can be attested to the Core i7. The extra charge for the Core-i7 processor is not really worth it.

Since there is no fan, the computer always runs quietly. Yet it does not heat up too much. An NVMe SSD assures a fast-running system. Exchanging the SSD might be possible. To do that, you would need to remove the bottom of the computer casing. The keyboard of the convertible left a good overall impression.

The IPS display pleases with stable viewing angles and a very good contrast. The brightness value is also favorable, although it could be even higher, since the device will be used in various places under various lighting conditions.

The razor-sharp QHD+ display has a negative effect on the battery life. 

In our practically relevant WLAN test, the runtime decreases by a good 5 hours compared to the Full HD model of the XPS 13. Users who need a battery life that is as long as possible should therefore choose the Full HD model.
