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
30.4 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms Incremento
↘ 14 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. » 74 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (27.2 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
40.8 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms Incremento
↘ 19.6 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. » 43 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (44 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 detected 26040 Hz50 % brightness setting

The display backlight flickers at 26040 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 26040 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 59 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 2255 (minimum: 43 - maximum: 142900) Hz was measured.

Questa è la quarta volta che Lenovo ha riutilizzato lo stesso case. Come sempre con ThinkPad, ottimi dispositivi input, così come le feature PowerBridge - che non ha praticamente concorrenti reali - sono uno standard. Considerando le sue dimensioni, l'X270 ha molte porte, il che lo rende flessibile nell'utilizzo. Le piccole dimensioni ne rendono facile e comodo l'utilizzo. In questo senso, non vi sono differenze rispetto ai suoi predecessori - dopo tutto è fondamentalmente lo stesso dispositivo.

Purtroppo, Lenovo ha commesso errori in alcune parti del X270. Innanzitutto, il sistema di raffreddamento: è un po' allarmante che un dispositivo dotato di un processore ULV raggiunga i 60° C (140 ° F) di temperatura in superficie - nonostante la spesso fastidiosa ventola di raffreddamento in funzione. Un altro aspetto negativo è il display full HD, che è significativamente più scuro rispetto al suo predecessore, con una bassa copertura colore. I punti deboli nella costruzione sono simili a quelli delle versioni precedenti. Il design di manutenzione era già un problema per l'X260: non è uno scherzo aprire il la cover. Sorprendentemente, le batterie esterne a 3 celle più piccole del computer offrono anche la durata della batteria più breve rispetto al suo predecessore.

ThinkPad serie x2xx Lenovo ha urgente bisogno di un restyling. A causa dei tanti piccoli problemi, non possiamo consigliare l'X270.

Se non si ha assolutamente bisogno di un notebook compatto che ha una flessibilità di configurazione della batteria (PowerBridge), davvero non possiamo consigliare il ThinkPad X270. Questo non solo a causa dei vari problemi sopra descritti - anche se solo quelli sarebbero sufficienti per noi, consigliamo di dare un'occhiata ai diretti concorrenti HP EliteBook 820 G4 e Dell Latitude 7280. In generale, è difficile trovare motivi per l'acquisto della X270, a meno che non sia necessario il PowerBridge e alcune features che sono particolarmente importanti per le grandi imprese (smart card, docking port, Ethernet). Il  Dell XPS 13 e il maggiore concorrente in-house di Lenovo, il ThinkPad X1 Carbon, per esempio, sono modelli che offrono maggiore qualità e un display più grande, pur essendo molto portabili. Ciò chiama in causa l'intera esistenza dei subnotebook. Un argomento potrebbe essere il prezzo - anche se i classici subnotebook da 12 pollici non sono realmente a basso costo.

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

Pro

+ comodi dispositivi di input ThinkPad
+ compatto e comodo da usare
+ flessibile utilizzo della batteria grazie al PowerBridge
+ molte porte per un portatile compatto

Contro

- alcune pecche nella costruzione
- dispositivo che si scalda sotto carico
- ventola di raffreddamento troppo spesso in funzione
- display più scuro rispetto al predecessore
- bassa copertura del colore
- manutenzione difficile
- batteria deludente

This is the fourth time Lenovo has reused the same case. As always with ThinkPads, the great input devices, as well as the PowerBridge feature – which basically has not real competitors - are definite pros. Considering its size, the X270 has a lot of ports, which means that it is very flexible to use. The small size also means that it is easy and comfortable to handle. In this respect, there are no differences to its predecessors – after all it is basically the same device.


Unfortunately, Lenovo did mess up in some areas of the X270. First of all, the cooling system: It is a little alarming that a device equipped with a ULV processor reaches 60°C (140°F) surface temperature - despite the cooling fan running annoyingly often. Another downside is the full HD display, which is significantly darker than its predecessor's, with a similar low color space coverage. The weaknesses in manufacturing are also similar to those of the previous versions. The maintenance design was already an issue for the X260: it is no fun to open the BaseCover. Surprisingly, the computer's smaller external 3-cell batteries also offer shorter battery life than that of its predecessor.

Lenovo's ThinkPad X2xx series urgently needs a makeover. Due to the many little problems, we cannot recommend the X270.

If you do not absolutely need a compact notebook which has a flexible battery configuration (PowerBridge), we cannot really recommend the ThinkPad X270. This is not just because of the various problems described above – although those alone would suffice for us to recommend taking a look at the direct competitors HP EliteBook 820 G4 and Dell Latitude 7280. General, it is difficult to find reasons for buying the X270, unless you need the PowerBridge and some features that are particularly important for big companies (smart card, docking port, Ethernet). The Dell XPS 13 and Lenovo’s largest in-house competitor, the ThinkPad X1 Carbon, for example, are models that offer higher quality and a bigger display, while still being very portable. That calls into question the whole existence of subnotebooks. One argument might be the price – although the classic 12-inch subnotebooks are not really low-cost either.
