联想ThinkPad T590商务笔记本电脑评测：大而轻，屏幕差劲。

被屏幕耽误了。 联想ThinkPad T590是热门ThinkPad T490的更大版本。 更大的机身提供了一些优势，ThinkPad T590是迄今为止T系列中最轻的15.6英寸型号。 不幸的是，它在一个关键方面比T490更糟糕。

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↗ 17.2 ms rise
↘ 10 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. » 65 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.5 ms).
   ↔    Response Time 50% Grey to 80% Grey
37.2 ms ... rise ↗ and fall ↘ combined↗ 19.2 ms rise
↘ 18 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 48 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.7 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

联想ThinkPad T590商务笔记本电脑评测, review-unit provided by

联想ThinkPad T590是T系列中最轻巧，最紧凑的15.6英寸ThinkPad。在过去，人们不得不选择较小的14英寸型号，如果他们不想使用非常厚实和沉重的笔记本电脑。现在事情并非如此。不过，较小的联想ThinkPad T490可能仍然是大多数用户的更好选择。

对此的一个重要因素是T490和T590在很多方面非常相似。联想使用相同的主板设计，两者的材料和结构完全相同。联想ThinkPad T590拥有更大的机身，具有充足的连接和安全选项，但ThinkPad T490也提供这些功能。优质键盘和非常舒适的输入设备也是如此，尽管T590在这个领域确实有一些优势，这要归功于它的小键盘。此外，ThinkPad T590续航时间T490，至少在FHD版本中，因为它具有更大的57 Wh电池。 ThinkPad T590提供了高于平均水平的CPU性能，而ThinkPad笔记本电脑的风扇大部分都保持安静，不过T490的情况也是如此。

更大的屏幕可以被视为ThinkPad T590的一个优点。然而，与T490及其低功耗FHD屏幕相比，LCD面板的质量非常糟糕。色域和屏幕亮度更差。联想确实提供了一个4K UHD的面板，但绝大多数T590可能都只配备了FHD面板。其他弱点，例如难以打开的机身，microSD而不是全尺寸SD卡读卡器，高温和半速Thunderbolt 3端口。缺少的PowerBridge功能也是令人失望。

只有屏幕更好时，ThinkPad T590才是一台很好的笔记本电脑。

考虑到所有因素，我们仍然可以推荐ThinkPad T590作为同级别领先的15.6英寸笔记本电脑，因其具有出色的生产效率。尽管如此，我们认为ThinkPad T490才是更好的选择，特别是如果不需要小键盘的话。与HP EliteBook 850 G5等同级别的其他15.6英寸设备相比，ThinkPad具有更好的输入设备和更高的CPU性能，但屏幕更差——除非选择带有4K UHD屏幕的型号。
