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 | ||
|---|---|---|
| 13.2 ms ... rise ↗ and fall ↘ combined | ↗ 8 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 0.1 (minimum) to 240 (maximum) ms. » 33 % of all devices are better. This means that the measured response time is better than the average of all tested devices (20.3 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 18.8 ms ... rise ↗ and fall ↘ combined | ↗ 11.6 ms rise |  |

| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 31 % of all devices are better. This means that the measured response time is better than the average of all tested devices (31.7 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 8163 (minimum: 5 - maximum: 343500) Hz was measured. | |||

虽然Y740-15ICHg仍有其不足之处，但它消除了我们对其直接前身Y730-15ICH的一半不满。新的屏幕极大地改善了黑白响应时间，并具有144 Hz的刷新率（对于NVIDIA G-Sync）。此外，GPU也得到了巨大的升级; RTX 2070 Max-Q的性能是之前GTX 1050 Ti的两倍多。所有这一切都是在没有系统风扇噪音大幅增加的情况下实现的，尽管表面温度肯定会明显上升。
Y740-15ICHg的其他值得注意的优点包括非常强大且持续的CPU性能，以及快速的系统性能，这要归功于它的三星PM981 NVMe SSD。该机器难以负担双烤，但CPU和GPU单烤以及正常游戏运行没有问题。确实，游戏玩家不可能在大多数游戏中在不调低画质的情况下达到144 fps +的稳定帧率，但拥有该选项仍然很不错。
虽然它在便携性和输入设备方面不尽如人意，但联想Y740-15ICHg是对其前代产品的重大改进，可以轻松处理大多数游戏，而且价格合理。
这种外观设计虽然非常规，但在美学和触觉方面都取得了成功，尽管从耐久性的角度来看，它确实留下了一些不足之处。特别是不够坚固的显示器盖，和受压能力一般的基座。输入设备只是够用;键盘的短行程和软绵绵的反馈以及触摸板按钮的令人厌烦的驱动很容易被其竞争对手（如XPS 15和MSI GS65）所超过。不过维护倒是很不错。
Y740-15ICHg价格合理，我们的配置价格为14899元。它的功能足以在高设置下以60FPS运行几乎所有现代游戏。竞争对手包括Alienware m15，Razer Blade 15，Acer Predator Triton 500和MSI GE75，他们都有其独特的优缺点。总而言之，Y740是对于其前身的重大改进，适合那些想在合理预算范围内寻找强大的游戏本的人。
