Display Response Times

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
26 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 11 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 0.8 (minimum) to 240 (maximum) ms. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.7 ms).
       Response Time 50% Grey to 80% Grey
32 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 17 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 17 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

联想瑜伽720-13IKB是一款坚实耐用的多功能13寸变形本,它重量轻,尺寸小,拥有360度的铰链。它基于英特尔的最新一代 酷睿 i5-7200U Kaby Lake处理器,提供了8 GB的运行内存,由于256 GB固态硬盘的速度很快,该机运行速度非常快。结合全高清显示屏,购买价低至850美元。

该机采用的永恒的极简主义设计理念——“只做必须”,和材料的选择,赢得了我们的认同。 Yoga 720-13IKB几乎在各方面都做的很好,顺利地通过我们验证和测试。然而,我们还是希望能有不止三个接口。

总的来说,联想Yoga 720-13IKB留下了积极的印象,尽管我们不完全理解SD卡读卡器被遗漏的背后原因。可能是就联想在试图模仿苹果的简约——“少是多”的方法。最终,消费者将决定该妥协是否值得。我们的的测试机提供稳固稳定的表现。我们在使用笔记本电脑时没有遇到任何严重问题。输入设备使用起来让人愉悦。所有的这些,只需要850美元就可以获得,非常实惠。
