Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
30.4 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for 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).
       Response Time 50% Grey to 80% Grey
40.8 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise
↘ 19.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for 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 (44.1 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: 60 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 1486 (minimum: 43 - maximum: 30860) Hz was measured.

Esta é a quarta vez que a Lenovo reutilizou  mesma carcaça. Como é sempre com os ThinkPads, os ótimos dispositivos de entrada, bem como o recurso PowerBridge – que basicamente não têm oponentes reais - são pros definitivos. Considerando o seu tamanho, o X270 possui muitas portas, o que significa que é muito flexível para usar. O pequeno tamanho também significa que é fácil e confortável de manusear. Neste respeito, não há diferenças com seus predecessores – depois de tudo é basicamente o mesmo aparelho.


Infelizmente, a Lenovo estragou algumas áreas do X270. Primeiro que nada, o sistema de resfriamento: É um pouco alarmante que um aparelho equipado com um processador ULV atinja 60°C (140°F) de temperatura na superfície - apesar de que a ventoinha irritante esteja funcionando muito frequentemente. Outro ponto negativo é a tela full HD, que é significantemente mais escura que seu predecessor, com uma similar baixa cobertura do espaço de cores. As fraquezas na construção também são similares para a aqueles das versões prévias. O design da manutenção já era um  problema para o X260: não é nada agradável abrir a pare inferior. Surpreendentemente, as bateria externas de 3 células do computador também oferecem durações de bateria mais curtas que as do seu predecessor.

A série Lenovo ThinkPad X2xx precisa de uma reforma urgentemente. Devido aos muitos pequenos problemas, não podemos recomendar o X270.

Se você não precisar de um portátil compacto que tem uma configuração flexível da bateria (PowerBridge), não podemos realmente recomendar o ThinkPad X270. Isto não se deve apenas aos vários problemas descritos acima – embora apenas esses seriam suficiente para que recomendemos dar uma olhada nos concorrentes diretos como o HP EliteBook 820 G4 e Dell Latitude 7280. Em geral, é difícil encontrar motivos para comprar o X270, a menos que precise do PowerBridge e de alguns recursos que são particularmente importantes para grandes empresas (smart card, porta docking, Ethernet). O Dell XPS 13 e o maior concorrente interno da Lenovo, o ThinkPad X1 Carbon, por exemplo, são modelos que oferecem maior qualidade e uma tela maior, enquanto é mais portável. Isto faz questionar toda a existência dos subportáteis. Um argumento pode ser o preço – embora os subportáteis clássicos de 12 polegadas também não são realmente de baixo custo. 

Pro

+ Dispositivos de entrada ThinkPad confortáveis
+ Compacto e bom para manusear
+ Uso flexível a da bateria graças ao PowerBridge
+ Muitas portas para um portátil compacto

Contra

- Algumas fraquezas na fabricação
- Esquenta sob uso intenso
- A ventoinha funciona com muita frequência
- Tela mais escura que a do predecessor
- Baixa cobertura do espaço de cores
- Manutenção difícil
- Duração pobre da bateria

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.
