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 | ||
|---|---|---|
| 36 ms ... rise ↗ and fall ↘ combined | ↗ 18.8 ms rise |  |
| ↘ 17.2 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. » 93 % 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 | ||
| 49.6 ms ... rise ↗ and fall ↘ combined | ↗ 24.4 ms rise |  |
| ↘ 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. » 84 % 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 detected | 1250 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 1250 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 1250 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8715 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Cons
- 没有microSD插槽
- 只有一个SO-DIMM插槽
- 压力测试后降频
- 电池运行下的GPU限制
- 负载下温度极高
即使听起来像是ThinkPad E590的升级款：但事实是，ThinkPad E15与其前身仍然很像。产品的基本概念没有改变，但联想已在细节上进行了努力。仍然有非常好的ThinkPad键盘和TrackPoint，在这个价格区域中很少见。铝和塑料制成的机身坚固耐用，可升级性堪称典范-至少在大容量存储方面。
与较小的ThinkPad E14一样，使用较薄的机箱意味着某些功能会丢失。其中之一是microSD插槽。第二个RAM插槽也取消了。 E15与它的较小型号的不同之处在于，缺少的功能并不是这里最大的问题。对于ThinkPad E15，问题在于冷却系统，简直不堪重负。在压力测试中，ThinkPad必须大量限制CPU和GPU性能。在这种情况下，降频也可能发生在日常使用和玩游戏中。此外，机身温度非常高，最热处温度超过65°C。当然，这仅存在在压力测试中，但在要求不高的The Witcher 3测试中，机身变得几乎一样热。
温度太高：只有在散热压得住的情况下，才应内置独立GPU。不幸的是，联想ThinkPad E15并非如此。
总体而言，我们不建议为Lenovo ThinkPad E15选配独显。如果无法充分散热，则将无法发挥完全实力。同时，核显版本可能物有所值–作为ThinkPad E14的较大版本和适用于家庭办公的出色笔记本电脑。
