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 | ||
|---|---|---|
| 30.8 ms ... rise ↗ and fall ↘ combined | ↗ 16.8 ms rise |  |
| ↘ 14 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 (21 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||

| 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. » 95 % of all devices are better. This means that the measured response time is worse 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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured. | |||

- 无法加装WWAN
- 电流噪音
- 亮面屏
- 没有更亮的LCD和更大的内存
- 屏幕响应慢
ThinkPad X390 Yoga延续了ThinkPad翻转本的传统。这台13.3英寸超极本有很多东西可供选择。但是，我们还是必须要提到一些弱点。
例如，缺少用于在平板电脑模式下保护按键的“Lift&Lock”键盘。这很致命，因为大多数翻转本都有这一功能。WWAN也不再可选。我们还注意到一个恼人的电流噪音，屏幕亮度也不佳——特别是考虑到它是块亮面屏。显然，与普通的ThinkPad X390不同，没有32 GB RAM的选项。而且RAM是焊死的，不能被扩展或替换。 LCD面板的响应时间也令人失望。
从更积极的方面来说，我们有更新的，一如既往稳定和坚固的机身，同时比其前身更轻薄。虽然键盘缺少其“Lift&Lock”机制，但毫无疑问它的手感非常好——至少如果你忽略了它比正常尺寸略小的事实。各种输入选项（触摸板，TrackPoint，触摸屏和手写笔）都非常易于使用。 ThinkPad翻转本的另一个灵活的方面是它的接口选择。与其前代产品相比，它现在具有额外的USB-C端口。这使用户能够连接与其他ThinkPad兼容的机械扩展坞——这是面向大型企业的一个重要卖点。除了亮面屏，X390 Yoga的屏幕可以提供高对比度和良好的色域覆盖。 CPU性能也得到了提升。它仍然不是特别令人印象深刻，无法与其他ThinkPad保持一样的水平，但它现在可以比其前代产品承担更长时间的负载。X390 Yoga的其他优点是安静的冷却风扇和慷慨的保修计划。
ThinkPad X390 Yoga是一款适合商业环境的高品质翻转本。其特别好的输入设备非常有吸引力。
总的来说，联想ThinkPad X390 Yoga的积极方面明显超过了它的缺点，这使得我们可以推荐它。其竞争对手戴尔Latitude 7390二合一和HP EliteBook x360 1030 G3也提供了相当多的产品，甚至可以在某些领域超越ThinkPad。例如，HP EliteBook具有更亮的屏幕和更好的续航时间。 ThinkPad Yoga在输入设备方面占据优势，并且还提供智能卡插槽或机械对接端口等功能，这应该使其对企业用户很有帮助。
