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 | ||
|---|---|---|
| 28.8 ms ... rise ↗ and fall ↘ combined | ↗ 8.4 ms rise |  |
| ↘ 20.4 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. » 74 % 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 | ||
| 55 ms ... rise ↗ and fall ↘ combined | ↗ 19 ms rise |  |
| ↘ 36 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. » 91 % of all devices are better. This means that the measured response time is worse than 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 detected | 217 Hz | ≤ 40 % brightness setting |  |
The display backlight flickers at 217 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 40 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 217 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. 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. | |||

Pros
+ 安静
+ 灵活
+ 附带主动式手写笔
+ 优秀的系统性能
+ 优秀的触控屏幕
+ 非常快速的无线网络
+ 优秀的键盘，但是打字声有些响
Cons
- 屏幕上盖稳定性
- 高发热量，负载下降频
- 仅一年质保
- 色域覆盖范围小
- 屏幕镜面，亮度略显不足
- 一般的无线上网续航时间
- 扬声器较差
- 屏幕转轴不够稳定
- 不支持最新接口
- 测试机型不支持移动网络
- 闪烁亮度控制
- 昂贵
ThinkPad P40 Yoga并没有完全说服我们。和尺寸稍大的工作站机型ThinkPad P50s相似，由于机身结构的设计，联想省去了许多最新技术（USB-C，USB 3.1，Thunderbolt，NVMe固态硬盘，M.2-2280）。而后者也用于售价更低的ThinkPad Yoga 460，它基于较老的ThinkPad Yoga 14。它的机身紧凑，因此2.5寸硬盘槽会浪费太大空间。
我们的测试机型有一些我们预想之外的缺点。它的坚固度有待提高，只需轻轻扳动屏幕就会出现水波纹。它的屏幕转轴也略显脆弱，在使用触控屏幕或稍微移动机身时它都会明显晃动。我们的测试机型——尽管有空余的M.2硬盘槽——并不支持手机移动网络，而质保也只有一年。它的镜面屏幕的亮度对于户外使用来说也有些暗，屏幕的其他数据也很难让人满意。这台设备非常安静，不过它的温度也因此较高，这将会在负载下限制它的性能。
当然P40 Yoga有潜在消费者，不过如果不需要一块专业显卡的话还有更好的选择。生产商也浪费了它的很多潜能，因为它缺少很多最新的接口，同时还有一些不必要的限制如高价位。
P40 Yoga的优势明显是不同的使用模式，不过它也有由重量和转轴设计带来的问题。甚至一向是ThinkPad优势的键盘，也有稳定性的问题。它依然有非常优秀的输入设备，但相比最新ThinkPad机型略逊一筹。
ThinkPad P40 Yoga面向一个特别的用户群体。如果你同时需要专业显卡和变形本设计，那么除了P40 Yoga没有任何其他的选择。不过，如果你不需要Quadro显卡的话，则可以考虑更轻盈的ThinkPad X1 Yoga或着更实惠的ThinkPad Yoga 460。
如果作为变形本评分的话它的分数是81%
