Recensione breve del Portatile Chuwi LapBook Air 14.1 (N3450, FHD)

Allen Ngo (traduzione a cura di G. De Luca), 11/01/2017

Attraente ma lento. Il Chuwi clone del MacBook Air sicuramente è bello e somiglia ad Ultrabooks che costano il doppio. Tuttavia analizzando a fondo, si trovano alcune pecche.

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
29.2 ms ... rise ↗ and fall ↘ combined↗ 16 ms Incremento
↘ 13.2 ms Calo
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. » 69 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.6 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
32.8 ms ... rise ↗ and fall ↘ combined↗ 12.8 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. » 19 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.5 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 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: 55 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9257 (minimum: 43 - maximum: 247500) Hz was measured.

Recensione: Chuwi LapBook Air 14.1. Modello fornito da Chuwi
Recensione: Chuwi LapBook Air 14.1. Modello fornito da Chuwi

Il LapBook Air è interessante considerando il prezzo di $400. Il display IPS da 1080p è definito, il dispositivo di archiviazione secondario è raro, e c'è anche una tastiera retroilluminata. Sfortunatamente, il produttore ha fatto dei tagli quasi ovunque per tenere basso il prezzo.

La qualità non è alla pari con altre alternative note. Il nostro dispositivo ha un leggero effetto bleeding del display, la retroilluminazione della tastiera è poco omogenea, il tasto Ctrl è rotto, una porta USB non funziona, ci sono molti crashes, e le estremità cedono. Raccomandiamo di provare ogni porta e tutti i tasti prima di comprarlo. Inolter il processore a raffreddamento passivo Celeron, l'SSD, e l'alimentatore sono molto lenti. Coloro che vogliono qualcosa di più potente si troveranno meglio con un più vecchio ULV Haswell con tastiera più salda e trackpads più preciso. Se dovete usarlo prevalentemente per riproduzione video, tuttavia, il LapBook Air non è male.

Il LapBook dovrebbe risultare utile se lo usate per web browsing, word processing, e riproduzione video.

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