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 | ||
|---|---|---|
| 17.6 ms ... rise ↗ and fall ↘ combined | ↗ 3.6 ms rise |  |
| ↘ 14 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. » 36 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 28.4 ms ... rise ↗ and fall ↘ combined | ↗ 11.2 ms rise |  |
| ↘ 17.2 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 0.165 (minimum) to 636 (maximum) ms. » 34 % of all devices are better. This means that the measured response time is better than 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 detected | 222.2 Hz | ≤ 49 % brightness setting |  |
The display backlight flickers at 222.2 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 49 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 222.2 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 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pros
+ 全新的支架设计方便放在腿上使用
+ 优秀的无线模组
+ 舒适易用的键盘
+ 宽阔准确的触控板，优秀的内置按键
+ 屏幕色彩绚丽，色域覆盖合理
+ 快速的系统性能
+ 单独销售的拓展模组
+ 打开后盖可以维护升级部件
Cons
- 机身仅管坚固，但抗扭折能力相比Surface Pro和其他竞争机型较弱
- 打开时不易于一只手握持
- 一般的亮度和对比度
- 在亮度设置一半以下时屏幕闪烁
- 持续负载下的处理器／显卡性能受到散热限制；几乎是立刻就会降频
- 显卡性能低于Surface Pro m3机型
- 在负载下十分烫，待机时温热
- 扬声器最多算是一般
- 电池续航低于平均水平
- 价位高
联想曾经是变形本市场的先驱之一，不过X1 Tablet（测试机型售价1549美元）标志着这家生产商首次为ThinkPad系列采用微软Surface式设计。这台设备旨在为商务用户提供一个除Surface Pro之外的选择，在很多方面它都做得十分成功。X1 Tablet的舒适输入设备是我们所熟悉的ThinkPad风格，提供了舒适、易用的体验。同时它作为被动散热机型，提供了出色的设备，可维护性和升级空间（这大概会受到大企业IT部门的欢迎），和一系列单独销售的模块化拓展设备，帮助提供更多功能和接口。它改进的支架设计让我们印象深刻，它相比Surface Pro更适合于放在腿上使用。
尽管有一些弱点，X1 Tablet仍然是联想对Surface Pro 4的强力挑战，感兴趣的用户在使用后可能会十分满意。
用户在选购之前也需要考虑它的一些缺点。例如，尽管它是一台ThinkPad，可开启的后盖设计和一些塑料机身结构让它相比一体式镁铝合金机身（如Surface Pro）抗弯折能力较弱。同时这台设备发热量较大（至少我们的测试机型），这可能会给长时间握持使用带来不便。尽管我们测试的是顶配的酷睿m7机型，我们对这个配置选项的实际意义有些怀疑，因为相比m3机型它十分昂贵（需额外支出350美元），而散热的限制让它相比m5和m3并没有实际的优势。最后，它的电池续航时间相比直接竞争对手也略逊一筹，甚至相比一些大尺寸主动散热的超极本也较短。
可能选择酷睿m3或m5的机型会改进以上的一些问题，而不会牺牲很多实际性能——同时也能节省不少的预算。
