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
44.8 ms ... rise ↗ and fall ↘ combined	↗ 21.2 ms rise
44.8 ms ... rise ↗ and fall ↘ combined	↘ 23.6 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. » 99 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (24.1 ms).
↔ Response Time 50% Grey to 80% Grey
71.2 ms ... rise ↗ and fall ↘ combined	↗ 33.2 ms rise
71.2 ms ... rise ↗ and fall ↘ combined	↘ 38 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 636 (maximum) ms. » 98 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (38.2 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

2427 Hz

≤ 50 % brightness setting

The display backlight flickers at 2427 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 2427 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9716 (minimum: 5 - maximum: 151500) Hz was measured.

The Lenovo ThinkPad T490-20N2004EGE laptop review. Test device courtesy of notebooksandmore.de.

无论有没有独显，联想ThinkPad T490都是一款出色的商用笔记本电脑。没有独显的型号在某些领域比带独显的ThinkPad T490稍好一些，它将整体评级从我们给配备MX250的同型号产品的90％提升到91％。

除此之外，我们的评测单元比独显版ThinkPad T490具有更好的续航时间。前者比后者温度更低，并且不会受到恼人的扬声器噪音的影响。联想在很大程度上通过BIOS更新消除了这一点，所以它不应该影响任何ThinkPad T490 SKU。

此外，核显版本的T490由于较弱的CPU，在进行压力测试时也不会受到限制。而其他T490的亮点仍然存在，例如坚固轻巧的外壳，梦幻般的输入设备以及明亮且色彩准确的显示屏。我们也很欣赏多种接口选择和高于平均的CPU性能。

然而，两种型号都存在很大的相同缺点。低功耗屏幕的响应时间很短，而只包含microSD卡读卡器而不是全尺寸卡读卡器似乎有些失策。同样，虽然我们喜欢联想为其配备的雷电3端口，但我们无法理解为什么只允许它使用两个PCIe通道。此外，拆卸和重新组装外壳是一件痛苦的事情，而可拆卸电池的缺乏使得T490的灵活性低于其前代产品。

更低温，更持久：联想ThinkPad T490的核显版在某些领域比独显版更好，是一款出色的商务笔记本电脑。

总的来说，核显版的T490对于那些不需要GeForce MX250带来的附加图形功能的人来说应该足够了。如果您偶尔喜欢下班后玩游戏或需要可以处理视频编辑的笔记本电脑，那么带有独显的T490在我们看来是更好的选择。
