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 (21 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. » 41 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.9 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 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||

First Impressions
如果没有与2018型号的直接比较，你很难注意到第7代ThinkPad X1 Carbon的尺寸和重量上的优势。新机身的稳定性和构建质量都很好，但旧机型的键盘更好。
我们已经熟悉去年的屏幕并且质量仍然很好（即使需要校准），但考虑到入门级FHD面板的亮度很高，我们本来希望看到更昂贵的WQHD选项有更亮的背光。
到目前为止，噪音也很好; 风扇并不烦人，扬声器也得到了改进。
不幸的是，续航时间受到较小电池的影响。 我们已经迫切希望了解低功耗1080p屏幕在这方面的表现。
