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 | ||
|---|---|---|
| 36.8 ms ... rise ↗ and fall ↘ combined | ↗ 19.2 ms rise |  |
| ↘ 17.6 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. » 94 % 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 | ||
| 51.2 ms ... rise ↗ and fall ↘ combined | ↗ 26.8 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 0.165 (minimum) to 636 (maximum) ms. » 87 % 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 | 1000 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 1000 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 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering. 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. | |||

联想ThinkPad L390 Yoga是一款价格合理，制作精良的13英寸翻转本。联想并没有放弃让我们对其他ThinkPad留下深刻印象的东西以降低成本。ThinkPad使用玻璃纤维，铝和镁来制造L390 Yoga，就像它更昂贵的同类一样，这使得L390 Yoga看起来更加优质并且感觉坚固。它的宽屏幕边框使其看起来过时，但这仍然也是其他ThinkPad的特点。键盘提供了我们在其他ThinkPad上所喜爱的同样出色的打字体验，但是联想省略了它在更昂贵的翻转本上使用的升降和锁定机制，这有些遗憾。
与L380 Yoga相比，Whiskey Lake处理器的升级也带来了性能的适度提升，但散热系统在持续负载下很快就会不堪重负，这会导致暂时的降频。因此，我们不确定i7版本在我们的测试中的表现如何。风扇也非常安静，但它以高温作为代价。
“联想ThinkPad L390 Yoga是对L380 Yoga的增量升级。Whiskey Lake处理器带来了性能上的提升，联想再次推出了廉价的翻转本ThinkPad，但它不会影响ThinkPad那令人印象深刻的工艺，输入设备和性能。”
我们也喜欢这块高速固态硬盘，而联想则为这台机子配备了比其前代产品更新更快的英特尔Wi-Fi模块。廉价ThinkPad仍然易于维护和修复，这是另一个好。
显示屏再次让我们有两种想法。它具有稳定的视角，而且尽管有光泽的表面，在室外仍然可读，但它亮度太低，颜色不准确。总体而言，L390瑜伽是一款令人印象深刻的商务翻转本，可在有限的预算范围内提供ThinkPad体验。
