Display Response Times

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
38.8 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise
↘ 17.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 96 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.1 ms).
       Response Time 50% Grey to 80% Grey
61.6 ms ... rise ↗ and fall ↘ combined↗ 30.8 ms rise
↘ 30.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 96 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (40 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9440 (minimum: 43 - maximum: 142900) Hz was measured.

这次我们可以长话短说:ThinkPad T490s是一款非常优秀的商务笔记本电脑,也是目前最好的笔记本之一。仅8999元的售价也具有一定的性价比。”

我们可以在此时结束我们的总结,但是当您将ThinkPad T490与其前身和联想的其他14英寸笔记本电脑进行比较时,情况会稍微复杂一些。对比当前的高质量商务本,可以看出所有系列都比以往更加相似。这包括T490,T490s,X1 Carbon以及新款X390,它们甚至与T490s共享主板。虽然存在一些差异,但是当您查看类似装备的SKU时,客户会得到几乎相同的四台笔记本,而我们甚至没有包括其他制造商的竞争对手。

在过去,T4x0s型号通常是普通T4x0的更薄版本,它通常配备更好的组件,并且在性能方面没有落后。这与新款T490有所不同。是的,新机身是成功的,质量也比常规T490高出一截,但T490s在性能上落后。这显然包括图形适配器,因为不再有独立显卡,而且还有处理器性能。后者受制于功率较小的散热方案,甚至性能不如前一代产品。

在我们看来,ThinkPad T490s就是一台更便宜的X1 Carbon(或者说是X1 Carbon Lite)。它更大更重,但提供类似的性能以及相同的键盘设计。顺便说一句,键盘的质量与更昂贵的X1 Carbon相当,主观上比T490和戴尔,富士通或惠普的竞争还高出一截。 T490s的接口情况也让我们想起了X1 Carbon,尤其是那microSD读卡器尴尬的位置摆放。

我们很欣赏这次更新的屏幕选项,经过评估的低功耗1080p雾面屏幕给人留下了极大的印象,除了响应时间较慢。我们预计它将成为T490s和普通T490最受欢迎的显示选项。亮度非常好,图像质量受益于高对比度,尽管是雾面屏,但并不存在大果粒现象。该面板还覆盖了较小的sRGB色域,色差非常低,尤其是在校准后。这意味着显示器还可以处理一些图片编辑——如果T490有一个全尺寸的SD读卡器,它甚至可能是摄影师的一个有趣的选择。

更薄的机身,更好的显示屏,更好的键盘,更长的续航时间——更差的CPU性能,没有独立显卡,接口的折衷以及更多有限的维护选项。根据您的期望,新款T490将会很棒或者令人失望。

T490s目前比竞争对手更好,因为它只是商务本领域的一个非常完美的机子。有一些缺点,但其中一些与之前的型号有关,竞争对手也不完美。因此,我们为T490s颁发了编辑选择奖。我们将在接下来的几周内更新竞争对手的阵容,因此排名可能会很快改变。联想可能会为即将到来的AMD同行提供竞争对手。
