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↗ 15 ms Incremento
↘ 11 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. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.7 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 (42.8 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 not detected

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6262 (minimum: 43 - maximum: 142900) Hz was measured.

Lenovo Yoga 720-13IKB: courtesy of campuspoint

Il Lenovo Yoga 720-13IKB è un convertibile da 13" solido, duraturo e versati, con un peso contenuto, dimensioni ridotte, ed una cerniera a 360°. Si basa sull'attuale generazione Intel Core i5-7200U Kaby Lake, offre 8 GB di RAM, ed è adeguatamente veloce grazie al suo SSD con prestazioni elevate da 256 GB. Unitamente ad un display FHD, l'intero pacchetto può essere acquistato per US $850.

Il design minimalista senza tempo "nulla di più del necessario" e la scelta dei materiali ci ha convinto. Lo Yoga 720-13IKB spunta quasi tutte le caselle giuste ed è chiaramente basato su un approccio provato e riprovato. Cosa che in parte ci delude, infatti avremmo più di tre porte.

Nel complesso il Lenovo Yoga 720-13IKB ha lasciato un'impressione positiva sebbene non comprendiamo in pieno le ragioni dietro l'assenza del lettore SD. Sembra quasi che Lenovo provi ad imitare l'approccio minimalista Apple “less is more”. In definitiva, il cliente deve decidere se vale la pena o meno accettare questi compromessi. Il nostro modello ha offerto prestazioni solide e costanti, e non abbiamo rilevato seri problemi durante il periodo di utilizzo del portatile. I dispositivi di input sono stati piacevoli da usare, e considerando il tutto il prezzo di US $850 per un portatile moderno è più che giustificato.

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