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 | ||
|---|---|---|
| 30.4 ms ... rise ↗ and fall ↘ combined | ↗ 6 ms rise |  |
| ↘ 24.4 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 81 % 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 | ||
| 38 ms ... rise ↗ and fall ↘ combined | ↗ 15.2 ms rise |  |
| ↘ 22.8 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. » 51 % 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 | 219 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 219 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 219 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
+ 非常轻薄
+ 性能优秀
+ 二合一多用途
+ 优秀的键盘／触控板
+ 附带Wacom AES手写笔
+ 校准后出色的色彩／灰阶准确度
Cons
- 昂贵
- 机身略为脆弱不支持USB-C
- IPS屏幕亮度不足
- 一般的电池续航时间
整体上，联想X1 Yoga是一款优秀且设计合理的商务变形本，尽管它1700美元（约11047人民币）的售价绝不算便宜。Yoga继承了“标准”X1的一些特性：它的机身由碳纤维和镁合金制成，不仅轻盈纤薄，还搭配了360度旋转转轴，可以支持笔记本电脑模式，帐篷模式，简报模式和平板模式。主动式手写笔式相对Thinkpad Yoga 12的一大进步，它仍然同样小巧，可以储存在机身之内。当然手写笔对平板模式的帮助很大——但是长时间握着一台14寸的笔记本电脑并不是很容易。它的键盘延续了Thinkpad品质，触控板／指点杆的搭配也同样出色。
它的屏幕在校对之后可以说是联想设备中色彩准确的之一。它的色域覆盖范围也很优秀，遗憾的是最大亮度略低。
Thinkpad X1 Yoga成功实现了设计初衷，而价位也不低。
希望笔记本电脑可以用作平板的用户可以考虑搭配可拆卸键盘底座的Surface Book，不过它的售价更高。惠普Spectre x360 13可能不太适合商务用途，但配置相同而售价仅1200美元（约7798人民币）让它也值得推荐。联想自家的Thinkpad Yoga 460与X1 Yoga定位相当，不过它较为笨重，售价也更亲民。较老的Thinkpad Yoga 14依然值得参考：搭配全高清屏幕，独立显卡，前代处理器，现在的售价仅900美元（约5848人民币）。
