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 | ||
|---|---|---|
| 33.6 ms ... rise ↗ and fall ↘ combined | ↗ 18 ms rise |  |
| ↘ 15.6 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. » 89 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||

| 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. » 74 % 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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pros
+ 坚固的机身
+ 出色的键盘
+ 不错的IPS屏幕
+ 比较安静
+ 系统性能强
+ 价格低廉
Cons
- -没有键盘背光（甚至不能选配）
- 仅有microSD读卡器
- AMD处理器并未充分发挥其潜力
- 只有单通道RAM
- 在某些部件中，用料不如E480 / E490
- 只有12个月保修
ThinkPad E485给人的印象略显复杂。它本身就是一款坚固的入门级商用笔记本电脑，具有坚固的外壳，漂亮的显示屏和出色的输入设备。但是，如果将它与ThinkPad E480（与Intel处理器相同的型号）进行比较，则存在一些差异。我们主要讲的是缺少键盘背光，甚至不作为选项提供，还有基座单元顶部的塑料材料质量稍差。有时候我们觉得制造商想要人为地将它与英特尔车型保持距离。
当然ThinkPad E485的价格较低，大多数用户应该能够忍受材料上的差异。另一个问题是稍微差一点的硬件。虽然每个人都知道集成的AMD GPU可以从双通道RAM中得到性能提升，但遗憾的是，所有OEM型号都是单通道。虽然您可以相对容易地升级，但原则上8 GB应该足以满足许多用户的需求，而更多RAM也需要更多预算。如果联想直接内置两个4 GB模块，情况会好一些。但最重要的问题可能是更高的功耗导致电池寿命缩短。这是否仅仅是由于缺乏优化或AMD的功耗更大我们不能确定。
错失的机会：与其英特尔兄弟相比，ThinkPad E485显示出与AMD处理器无关的一些弱点。例如，为什么没有键盘背光这一点我们难以理解。然而，对于任何能够忍受这种情况以及更短的电池续航时间的人，ThinkPad E485是一台性价比和可靠性都很高的入门设备。
ThinkPad E485还提供了一系列优势，而这个优惠价格在这个价格范围内并不是特定的。该处理器为大多数任务提供了足够的性能，并且由于三星的快速SSD，您可以期待在日常操作中具有快速的响应能力。此外，它还有一个不错的IPS显示屏（但是，根据供应商的不同，可能会有一些小的差异）。基于其较低的售价，我们还是可以推荐E485的。
更新：不幸的是，Innolux屏幕在我们的测试中比AU Optronics的模型更糟糕，特别是在亮度方面。使用Innolux屏幕，整体评估分数将从86.4降至85.8％。不幸的是，您在购买设备时对所使用的屏幕面板没有任何知情权，您需要“抽奖”。
