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 ms ... rise ↗ and fall ↘ combined↗ 17 ms Incremento
↘ 13 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. » 73 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.9 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
39 ms ... rise ↗ and fall ↘ combined↗ 19 ms Incremento
↘ 20 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. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.4 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 990 Hz ≤ 20 % brightness setting

The display backlight flickers at 990 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 990 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8895 (minimum: 43 - maximum: 142900) Hz was measured.

Modello di test fornito da Trekstor

Con il Primebook C13, Trekstor lancia sul mercato un convertibile da 13", che brilla, soprattutto, per la dimensione del display e per l'espandibilità. Le prestazioni di sistema sono sufficienti per semplici applicazioni da ufficio e per la navigazione internet. Considerando che lo spazio di archiviazione è limitato, la presenza si uno slot vuoto M.2 slot, è ben gradita. Pertanto lo spazio di archiviazione può essere ampliato senza difficoltà. 

Il Primebook C13 Trekstor è un semplice convertibile, che può sostituire un portatile, grazie alle sue dimensioni. Ma non dovete aspettarvi troppo in termini di performance. Questo convertibile è adatto solo per navigazione web e lavori da ufficio.

Con il Trekstor Primebook C13, non sarete in grado di fare molto di più rispetto a quanto detto (es. navigazione web e lavori da ufficio). Il dispositivo gestisce giochi molto semplici, ma non è adatto all'editing immagini, ad esempio. Siamo soddisfatti del design e della qualità di costruzione. Il dispositivo beneficia di una struttura sottile, in modalità tablet. Lo schermo molto riflettente non è l'ideale con l'interfaccia touch. Notiamo riflessi anche in ambienti chiusi.

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