结论 - 极其轻盈，但不乏牺牲
Dynabook Portege Z40L-N 是市场上最轻的 14 英寸 Windows 笔记本电脑之一。虽然这样的成就通常会伴随着严重的缺点，但 Dynabook 却在重量轻的情况下集成了大量端口、可拆卸的 M.2 2280 SSD、全 sRGB 色彩以及舒适的键盘和触摸板。与较重的 14 英寸笔记本电脑相比，Dynabook 的便携性无论如何强调都不为过。 三星Galaxy Book Pro 14或 惠普 EliteBook X G1i 14 AI.
但缺点也是存在的。除了明显缺乏广域网支持外，CPU 和固态硬盘尤其容易出现性能节流现象，这一点与许多其他具有类似配置选项的子笔记本电脑相比尤为明显。机箱或骨架也比坚固的 MacBook Air 更容易弯曲和扭曲。 MacBook Air或 戴尔 XPS.因此，要求更高的用户可能仍然希望考虑更重的笔记本电脑，以获得额外的马力和刚性。

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 | ||
|---|---|---|
| 26.7 ms ... rise ↗ and fall ↘ combined | ↗ 12 ms rise |  |
| ↘ 14.7 ms fall | ||
| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 65 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.5 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 42.1 ms ... rise ↗ and fall ↘ combined | ↗ 19.6 ms rise |  |
| ↘ 22.5 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. » 68 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32 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 8320 (minimum: 5 - maximum: 343500) Hz was measured. | |||

The selection of devices to be reviewed is made by our editorial team. The test sample was provided to the author as a loan by the manufacturer or retailer for the purpose of this review. The lender had no influence on this review, nor did the manufacturer receive a copy of this review before publication. There was no obligation to publish this review. We never accept compensation or payment in return for our reviews. As an independent media company, Notebookcheck is not subjected to the authority of manufacturers, retailers or publishers.
This is how Notebookcheck is testing
Every year, Notebookcheck independently reviews hundreds of laptops and smartphones using standardized procedures to ensure that all results are comparable. We have continuously developed our test methods for around 20 years and set industry standards in the process. In our test labs, high-quality measuring equipment is utilized by experienced technicians and editors. These tests involve a multi-stage validation process. Our complex rating system is based on hundreds of well-founded measurements and benchmarks, which maintains objectivity. Further information on our test methods can be found here.
