Display Response Times
ℹ
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 | ||
|---|---|---|
| 24 ms ... rise ↗ and fall ↘ combined | ↗ 12.4 ms rise |  |
| ↘ 11.6 ms fall | ||
| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 50 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 33.6 ms ... rise ↗ and fall ↘ combined | ↗ 16.4 ms rise |  |
| ↘ 17.2 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 42 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.8 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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8715 (minimum: 5 - maximum: 343500) Hz was measured. | |||
First Impressions
Sem uma comparação direta com o modelo 2018, você dificilmente notará a vantagem de tamanho/peso do ThinkPad X1 Carbon de da 7ª geração, para ser honesto. Tanto a estabilidade quanto a qualidade de construção do novo chassi são ótimas, mas o teclado era melhor no modelo antigo.
Já estamos familiarizados com a tela do ano passado e a qualidade ainda é boa (embora você deva calibrá-la), mas considerando o painel FHD de nível de entrada mais brilhante, gostaríamos de ver uma luz de fundo mais clara para a opção WQHD mais cara também.
As emissões também são boas até agora; o ventilador não é irritante e os alto-falantes foram aprimorados.
A próxima atualização incluirá o desempenho da CPU, as medições da ventoinha e dos alto-falantes e a comparação do chassi com o atual ThinkPad da série T da Lenovo.
