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
31.6 ms ... rise ↗ and fall ↘ combined	↗ 18.4 ms rise
31.6 ms ... rise ↗ and fall ↘ combined	↘ 13.2 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. » 84 % 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
46 ms ... rise ↗ and fall ↘ combined	↗ 20.8 ms rise
46 ms ... rise ↗ and fall ↘ combined	↘ 25.2 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. » 77 % 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8719 (minimum: 5 - maximum: 343500) Hz was measured.

这台设计精良的Yoga 920是Yoga 900系列中最好的一台，它的提升不仅仅存在于硬件。得益于四核中央处理器，和极速MVMe固态硬盘，该机的性能得到了很大的提升。同时，其他方面也有所改进：现在，它拥有了2个雷电3接口，摄像头位置改善，键盘很优秀，支持触控笔而且机器续航时间良好。联想显然是有考虑到用户的反馈的。

铝合金外壳依然坚固好看，铰链设计依然存在。显示屏更亮了些，对比度和灰度都有所增强。不过，大小方面还是存在问题：联想的这台机器，是一台尺寸较大的变形本，导致在平板模式下，很难持握。当然，有些用户会喜欢大点的屏幕。“抬起即锁定” 功能的缺失，使得该机的按键一直处于凸起状态，所以用户得小心误触。负载下的节流，制约了中央处理器额外的潜在性能，当然，总体的性能对比之前还是有提升的。另一个提升是：之前类似Yoga 910处理器带来的风扇噪声的缺点，已经不存在了。

Yoga 920是一台设计精良而且富有吸引力的二合一设备。推荐那些喜欢诸如惠普 Spectre X360或者戴尔XPS 13这样13.3英寸变形本的用户，选购该机。
