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 | ||
|---|---|---|
| 22.8 ms ... rise ↗ and fall ↘ combined | ↗ 13.6 ms rise |  |
| ↘ 9.2 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. » 47 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (21 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 28.4 ms ... rise ↗ and fall ↘ combined | ↗ 15.2 ms rise |  |
| ↘ 13.2 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 | 221.2 Hz | ≤ 49 % brightness setting |  |
The display backlight flickers at 221.2 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 221.2 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pros
+ 作为平板电脑／变形本相对易于维护
+ 非常优秀的输入设备
+ 高速系统性能
+ 合理的运行发热量
+ 可以接受的电池续航
+ 大幅改进的屏幕亮度和对比度
Cons
- 由于采用被动散热持续负载下的性能有所降低
- 屏幕的低频率闪烁可能会让一些用户无法接受
- 不支持Thunderbolt
- 扬声器品质较低
- 仅一年质保
今年的ThinkPad X1 Tablet（第二代）更新确实仅限于内部芯片组，而它的改变对整体性能的影响在我们的测试中缺并不小。例如，我们对它2015年m7处理器机型的三个不满意之处——持续运行处理器／显卡性能，表面温度和电池续航——都在这台新机型里至少在一定程度上得到了改进。它的处理器在持续运行时的性能仍然低于短时间的峰值性能，不过下降的幅度并不大，我们在Cinebench测试中得到的结果是它在持续运行时相比单次测试性能仅下降了12%（详见评测中的处理器部分），考虑到没有主动式散热系统，这并不是个太差的结果。同时，它的表面温度和电池续航时间都相对有所改善，对一些用途来说甚至可以说是十分出色。另外，它的屏幕效果也得到了一定的改进，主要是亮度和对比度（这也是我们去年最不满的部分之一）。
不过，我们也可以理解为什么很多用户会对它没有得到机身设计、接口选择和扬声器等方面的改进而有所不满。同类竞争机型也越来越多——包括一些新设备如戴尔 Latitude 12 5285 二合一设备，X1的自满可能会让它反而有所退步。除此之外，其他常见变形本也越来越便携，正在缩短与可分离键盘底座结合平板电脑设计的机型在重量和尺寸之间的差距。
时隔一年， ThinkPad X1 Tablet第二代仅仅在前代机型的基础上带来了略微的改进。不过它依然是为数不多的很好地结合了灵便与多用途的高端商务设备之一。
随着时间的流动，价位的差距和同类设备的稀少依然让X1保持着奢侈和独特的位置。对于移动商务用户来说，它是市场上为数不多的结合了可维护性，坚固性，易于管理等优势和平板电脑加可分离键盘设计的高端商务设备。对于适合的用户与适合的用途，尽管它缺少革新性的改进，也依然是个合理的选择。
