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 | ||
|---|---|---|
| 50.4 ms ... rise ↗ and fall ↘ combined | ↗ 11.6 ms rise |  |
| ↘ 38.8 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (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 (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 59.2 ms ... rise ↗ and fall ↘ combined | ↗ 24.4 ms rise |  |
| ↘ 34.8 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 95 % 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 detected | 215.5 Hz |  | |
The display backlight flickers at 215.5 Hz (worst case, e.g., utilizing PWM) . The frequency of 215.5 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. 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
+ 轻盈的镁合金机身
+ 坚固的机身
+ 优秀的散热控制
+ 长电池续航
+ 非常优秀的屏幕面板（色彩，对比度）
+ 优秀的输入设备
Cons
- 散射滤镜带来的粗糙显示质量
- 屏幕上盖薄弱
- 作为商务笔记本维护功能设计较差
- 扬声器较差
- 相比一些竞争对手售价较高
两年对信息产业来说就像是人的一生一样长了，而我们至少有这么长时间没有看到东芝对他们的高端超便携设备进行更新了。尽管机身有些过气，但Z30t-B1320的1.33千克重量仍然非常便携——同时它的镁合金机身和借口布局都非常优秀，我们需要考虑的只有内部硬件了。
由于升级到了Broadwell芯片组，它理所应当地成为了至今最优秀的Z30。它对于一般的性能测试都游刃有余，在电池续航、机身温度控制（合理的排风口设计和有效的散热效果）等方面也毫无问题。他的输入设备也依然时分优秀，屏幕也提供了出色的色彩还原，合理的分辨率和优秀的亮度／对比度。它当然也不是完美的。首先，这块触控屏幕——尽管有自身的优势——显示效果非常模糊，这是抗反光的散射滤镜（半磨砂效果）带来的副作用。它的机身尽管大部分都很坚固，但搭配的超薄屏幕上盖却特别脆弱。维护升级十分困难，因为它的螺丝隐藏在了橡胶垫脚下面——这对于一款高端商务设备来说让人十分难以理解。最后，它的扬声器弱于一些竞争对手，效果单薄低音很弱。
另外，Z30t的同类竞争产品也越来越多。戴尔Latitude 7000系列和联想ThinkPad系列在输入设备和机身坚固度方面仍然处于领先，更不用说它们更佳便于维护。惠普EliteBooks售价较高，但是也值得考虑。同时一些消费市场产品——尽管缺少以太网接口和拓展坞借口——仍然进入了商务世界，例如评分很高的XPS 13。Portege Z30t依然是一款有竞争力的产品，尽管设计有些过时但仍然非常值得参考。
