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 24510 Hz60 % brightness setting

The display backlight flickers at 24510 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 60 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 24510 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 55 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9304 (minimum: 43 - maximum: 247500) Hz was measured.

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
26.4 ms ... rise ↗ and fall ↘ combined↗ 14.8 ms Incremento
↘ 11.6 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. » 49 % 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
38 ms ... rise ↗ and fall ↘ combined↗ 20 ms Incremento
↘ 18 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. » 34 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.6 ms).

L'IdeaPad 520s-14IKB è un pacchetto complessivamente buono che fa bene molte cose ma ha anche delle pecche. Tuttavia, possiamo giustificarlo considerando il prezzo. Prima gli aspetti positivi: rispetto al predecessore, il design è più attraente ed il case non mostra pecche in termini di stabilità e costruzione. La buona stabilità aiuta anche la digitazione, quindi anche la tastiera ha una valutazione positiva, così come il TouchPad che è in linea con lo standard Microsoft Precision. L'autonomia è molto buona e nettamente migliore rispetto al predecessore, in quanto Lenovo ha usato una batteria più grande. La ventola spesso è spenta e quando ruota, è piacevolmente silenziosa. Sebbene il display sia lontano dalla perfezione (bassa copertura della gamma di colore), ha gli ottimi angoli di visuale classici degli schermi IPS e un contrasto sorprendentemente elevato.

Ma ci sono anche delle pecche. Ad esempio, il case si scalda molto sotto carico. In generale, il sistema di raffreddamento non è moto adeguato. Per quanto sia silenzioso, si nota evidente throttling nello stress test. Già con un loop di Cinebench, la CPU non mantiene le prestazioni massime. Non si comprende perché la connessione USB-C non supporti DisplayPort, e non funzioni per la ricarica. Che peccato! Purtroppo Lenovo usa solo una scheda 1x1-WLAN.

Nel complesso, l'IdeaPad 520s è un buon tuttofare, che convince con una buona autonomia ed un design attraente.

I punti negativi non sono abbastanza per evitare la raccomandazione dell'IdeaPad 520s-14IKB. E' un Ultrabook di relativo successo, che potrebbe interessare in particolare agli studenti, con la sua buona autonomia, la dGPU, e la comoda tastiera. Se confrontate ad esempio con il popolare Dell XPS 13, l'IdeaPad è più grande  e pesante, ma sempre molto portatile ed adatto ai giochi con la GPU GeForce. Inoltre è anche molto più economico. 

Dobbiamo precisare una cosa, in quanto al momento del test l'IdeaPad 520s-14IKB è già obsoleto. Una nuova versione dello stesso portatile con Core i5-8250U e GeForce MX150 potrebbe essere molto più attraente. Tuttavia, vorremmo vedere anche un sistema di raffreddamento più efficace.

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