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
26 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 8 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. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
47 ms ... rise ↗ and fall ↘ combined↗ 25 ms rise
↘ 22 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. » 74 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.5 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: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17077 (minimum: 5 - maximum: 2500000) Hz was measured.

我们希望从它的一些优势开始总结:Latitude 3470的屏幕搭配了磨砂表面,它的电池可以更换,同时接口配备在这个尺寸上也十分合理。它的键盘,尽管和更贵的Latitude无法相比,但也相比同价位的消费级产品更好。最后它的屏幕上盖和掌托采用了柔软的胶质表面,手感十分舒适。

遗憾的是,尽管它在细节上有不少优势。但由于戴尔为它的定位是以低价吸引用户。在很多方面它都节省了成本:它的散热系统不够有效,风扇几乎一直在旋转而设备依然会变得很热。戴尔也为它搭配了一个较慢的读卡器,卡槽也太浅不适合长期把卡放置其中。它的屏幕搭配了磨砂表面,而其他方面的表现则让人感到遗憾。它的商务功能也不是很让人满意:用户无法得到商务设备常见的指点杆、拓展坞接口和智能卡槽。

戴尔Latitude 3470表现优秀,而究竟是在哪方面呢?可能主要还是售价。除此之外,这台Latiude无法提供竞争对手惠普和联想所带来的丰富功能,同时它的部件选择对于德国境内的个人用户也十分有限。

综合考虑下我们无法推荐3470,除非你真的需要一台如此低价的商务系统。这台测试机的功能性无法和同类设备相提并论,当然它们的售价也更高。
