Tempi di risposta del Display

ℹ

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
17.6 ms ... rise ↗ and fall ↘ combined	↗ 10.8 ms Incremento
17.6 ms ... rise ↗ and fall ↘ combined	↘ 6.8 ms Calo
Lo schermo mostra buoni tempi di risposta durante i nostri tests, ma potrebbe essere troppo lento per i gamers competitivi. In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 14 % of all devices are better. This means that the measured response time is better than the average of all tested devices (25.9 ms).

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. » 26 % of all devices are better. This means that the measured response time is better than the average of all tested devices (41.4 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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

21740 Hz

≤ 20 % brightness setting

The display backlight flickers at 21740 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 21740 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8882 (minimum: 43 - maximum: 142900) Hz was measured.

+ SSD NVMe con drive bay secondario

- Luminosità del display deludente

- riproduzione del colore

- un anno di garanzia standard

I desktops business, compresi gli all-in-ones, sono parte del mercato che è più semplice notare rispetto all'affollato settore business. Di base non c'è niente di eccitante nel ThinkCentre M910z (la nostra confugurazione: $1,285), ha un design funzionale e sobrio e ha tutto ciò che occorre per una macchina da ufficio.

Ma non è una cosa negativa: mantenendo fede alla sua eredita, il ThinkCentre fa un buon lavoro con un design e features apprezzate come la (quasi) facile manutenzione e possibilità di upgrades oltre alla versatilità. Ma è anche silenzioso (anche sotto carico), veloce nelle operazioni generiche grazie alla sua CPU quad-core ed all'SSD NVMe, ed ha delle casse che smentiscono la classica brutta reputazione dei dispositivi business. Il display lascia sensazioni miste, la luminosità è scarsa e il touchscreen lascia desiderare (perché usarlo se non va bene?) - ma è antiriflesso! Infine i consumi sono bassi.

Non c'è nulla di particolarmente eccitante nel ThinkCentre M910z, ma non è un male; è funzionale, con un design sobrio e spunta tutte le caselle di una macchina da ufficio convenzionale.

In definitiva non ci sono molte grosse pecche nel ThinkCentre M910z—è un buon dispositivo business desktop che copre tutti gli aspetti base nel mercato business ed è facile da manutenere.

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