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
29.6 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 12.4 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 0.8 (minimum) to 240 (maximum) ms. » 70 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.6 ms).
       Response Time 50% Grey to 80% Grey
36.8 ms ... rise ↗ and fall ↘ combined↗ 18.8 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 0.9 (minimum) to 636 (maximum) ms. » 29 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.5 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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8568 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Toshiba Portégé X30. Review unit courtesy of Toshiba

东芝的这台机器很有竞争力。Portégé X30 有着让人印象深刻的工艺水平;将一切整合到了这样一个轻薄机身中,值得赞赏。两个雷电3接口,有助于减轻轻薄笔记本接口较少的问题。除此之外,它还提供了许多其他的有用接口。当然,我们更喜欢 X1 Carbon 所提供的接口,它们的造价更高,重量和占地稍微大点。而X1 上更为强大的键盘和维护方式,也使得用户在东芝和联想之间的选择变得更为困难。

该机重量轻,而且外壳坚固。键盘面板和底面板几乎不会弯曲,这点再次令人印象深刻。但是,如果施加压力,则A面容易弯曲; 这可能会在几个月或几年的使用后成为问题。此外的缺点,包括平庸的键盘,按键让人失望的布局方式,以及设备本身容易沾染指纹的特性。我们主要关注在于处理器性能:酷睿 i7-7600U在字面上看起来好像很棒。但却可能因为节流(为了保持温度),使得处理器性能下降。虽然我们无法确任原因,但会一定程度上影响整体性能。是的,X30在基准测试中的表现比对手要慢一些,但是在现实世界中,它仍然让人感觉很快,很快。

总的来说,东芝Portégé X30 是一款适合经常旅行和商务人士的优秀笔记本。良好的输入输出接口,漂亮的屏幕和精良的机身是这个优秀设备的亮点,而快速虹膜扫描部件和3年保修的优势则是锦上添花。
