Recensione breve del Convertibile Lenovo Yoga 720 12 (i5-7200U, 128 GB)

Versatile ma con una resistenza limitata. Il nuovo e compatto dispositivo Lenovo ha un interessante case in alluminio e versatili cerniere a 360°, ma funziona anche come subnotebook da ufficio convenzionale. Vantaggi importanti come lo schermo e i dispositivi di input sono bilanciati da qualche piccola pecca, e gli acquirenti più interessati dovrebbero trovarsi a loro agio.

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
26 ms ... rise ↗ and fall ↘ combined↗ 16 ms Incremento
↘ 10 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. » 43 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.3 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
32 ms ... rise ↗ and fall ↘ combined↗ 15 ms Incremento
↘ 17 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. » 17 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.1 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 not detected

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9953 (minimum: 43 - maximum: 588200) Hz was measured.

Recension: Lenovo Yoga 720 12. Modello di test fornito da Campuspoint.
Recension: Lenovo Yoga 720 12. Modello di test fornito da Campuspoint.

Gli utenti da ufficio noteranno due pecche sul ben progettato Lenovo Yoga 720-12IKB – il modulo WLAN relativamente lento e, più importante, l'autonomia che non copre una giornata intera di lavoro. La scelta del display è stata molto buona ad eccezione di chi intende effettuare editing immagini, e i bassi risultati benchmark dell'SSD non intaccano le prestazioni di sistema. La limitata gamma di porte è molto comune tra i dispositivi convertibili, quindi non possiamo criticare lo Yoga da questo punto di vista.

La stabilità del case non è perfetta, ma è comunque uno chassis di successo con un design carino e una buona qualità di costruzione. L'Active Pen in dotazione, i decenti dispositivi di input compreso il touchscreen e il sistema di raffreddamento efficiente, efficace e molto silenzioso rappresentano altri vantaggi.

Il convertibile versatile e compatto Lenovo Yoga 720 12 è economico e risponde a quasi tutte le esigenze degli utenti business mobile. L'unica vera pecca è la limitata autonomia.

Nel complesso possiamo raccomandare il modello di test.

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