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 | ||
|---|---|---|
| 27.2 ms ... rise ↗ and fall ↘ combined | ↗ 14.8 ms rise |  |
| ↘ 12.4 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 0.1 (minimum) to 240 (maximum) ms. » 66 % 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 | ||
| 40.4 ms ... rise ↗ and fall ↘ combined | ↗ 18 ms rise |  |
| ↘ 22 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. » 60 % 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 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||

联想IdeaPad S740融合了中端和高端配置。i7 CPU，GeForce GTX GPU，明亮的4K UHD显示屏，三星SSD，双Thunderbolt 3端口和窄边框可与Lenovo试图模仿的Dell XPS 15和HP Spectre x360 15相媲美。同时，较浅的键盘，有限的接口选项和相对不牢的机身更能体现出IdeaPad的廉价属性。相比较配置相同的Core i7-9750H CPU和GTX 1650/1650 Max-Q GPU，Lenovo的价格要比Dell和HP低一些，但打字体验会较差，设计也会较差。
但是，与其他IdeaPad机型相比，S740在视觉和性能方面轻松成为同类产品中的佼佼者。它具有入门级游戏本的性能，而没有游戏本笨拙或花里胡哨的外观。因此，与价格范围内的许多其他替代方案相比，该系统在游戏，办公，便携和价格之间取得了更好的平衡。
比一般的IdeaPad贵，但比Dell XPS或HP Spectre便宜。 IdeaPad S740适用于那些希望在不牺牲外观和便携性和太多性能的情况下买到高端全能本的人。
