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
12.8 ms ... rise ↗ and fall ↘ combined↗ 7.6 ms rise
↘ 5.2 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 14 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
15.6 ms ... rise ↗ and fall ↘ combined↗ 8 ms rise
↘ 7.6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 10 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (39.5 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 13573 (minimum: 43 - maximum: 2500000) Hz was measured.

联想Legion Y740-17ICH笔记本电脑评测. Test model provided by Lenovo US

大多数OEM通常会为其发烧级旗舰型号预留高端GeForce 80级GPU。这曾经是联想的Legion Y900系列,但制造商已经叫停该系列,将中档Legion Y700系列的顶配作为最高端产品。我们所得到的是一款采用高端GeForce GPU的中端游戏笔记本电脑,价格比Alienware m17华硕ROG G703,MSI GT75或Acer Triton 700等竞争对手的“超级”游戏笔记本价格更实惠。联想笔记本电脑在提供与这些发烧级笔记本相同的游戏性能下还便宜了几千元,主要是因为它的外形设计更简单。

由于出色的Turbo Boost可持续性,CPU性能比一般的 i7-8750H更快。考虑到轻薄的外形和高性能,核心温度和风扇噪音都低于预期。

因为军团Y740带有中端机身,第一印象并不像上述高端替代品那样强劲。联想比更坚固(和更昂贵)的MSI GT75或华硕ROG G703更容易发生弯曲和摇摆。我们的评测单元还有中等程度的漏光和偏色。它的键盘键更软,也更差。游戏玩家并不会失去性能,但较弱的机身强度和键盘按键将削弱整体游戏体验。

中端的Legion Y740系列的零售价比竞争对手的17.3英寸游戏笔记本电脑低得多,同时拥有相同的高端CPU和GPU。它在性能方面具有出色的优势,前提是您对没什么特色的外观设计和强度一般的机身没什么意见。
