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
30.8 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms Incremento
↘ 14.4 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. » 77 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.6 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
50.4 ms ... rise ↗ and fall ↘ combined↗ 27.6 ms Incremento
↘ 22.8 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. » 84 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (42.6 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: 55 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9418 (minimum: 43 - maximum: 247500) Hz was measured.

Recensione: Lenovo ThinkPad L470, fornito da CampusPoint
Recensione: Lenovo ThinkPad L470, fornito da CampusPoint

Con l'L470, Lenovo realizza un ThinkPad budget-oriented, che dovrebbe interessare soprattutto ad aziende e studenti.

Per un prezzo relativamente basso, l'L470 offre l'ottima e ben nota tastiera ThinkPad, ed il TrackPoint. Nel pacchetto c'è anche un display Full HD IPS, che non è scontato in questa fascia di prezzo. Il case in plastica non sembra di alta qualità, tuttavia, appare abbastanza robusto, e con cerniere buone. Essendo un portatile business, l'L470 offre una ampia gamma di porte. Ma dobbiamo lamentare l'assenza di una porta USB Type-C, tuttavia è poco male visto che Lenovo integra ancora una porta docking dedicata. Pertanto, non dipendete dalle docking stations USB Type-C. Di positivo anche il fatto che Lenovo monta ancora sull'L470 una porta VGA, una feature unica tra gli attuali ThinkPads. Per scuole, università e aziende che ancora usano proiettori vecchi, si tratta di un punto di forza. In questo caso, la buona autonomia e la flessibilità di una batteria sostituibile dovrebbero essere apprezzati, anche se non migliorano di molto il dispositivo.

Lenovo non fa grossi errori. Innanzitutto lamentiamo la presenza di un fastidioso rumore elettronico, un peccato, perché per il resto il dispositivo sarebbe completamente silenzioso in modalità idle. Il throttling della GPU, quando si usa la batteria, è comprensibile. La bassa copertura della gamma di colore del display non dovrebbe creare molti problemi con un dispositivo pensato per il business, ma è comunque da citare. Infine, dobbiamo criticare la garanzia standard di un solo anno, non abbastanza.

Vincitore nel rapporto prezzo/prestazioni: con un prezzo basso e buone features, come la porta VGA, e la batteria sostituibile, l'L470 è un interessante portatile business da 14".

Nonostante queste pecche, l'L470 merita una raccomandazione per il buon rapporto prezzo/prestazioni. Rispetto al concorrente più prossimo, l'E470, il più costoso L470 si distingue per una porta docking station dedicata, una porta VGA e la batteria sostituibile. Tuttavia, con la Nvidia GeForce 940MX, l'E470 è più interessante per i giocatori occasionali. Soprattutto, l'L470 supera l'HP ProBooks 440 ed il 640 grazie al display IPS, in quanto entrambi i Probooks hanno schermi TN. I concorrente più forte è il Dell Latitude 5480, che, in termini di prezzo, compete di più con il ThinkPad T470 che con l'L470.
