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
31.2 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 12.4 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. » 79 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.7 ms).
       Response Time 50% Grey to 80% Grey
40.8 ms ... rise ↗ and fall ↘ combined↗ 19.2 ms rise
↘ 21.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 49 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.3 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 18300 (minimum: 5 - maximum: 2500000) Hz was measured.

In review: Dell Latitude 7480. Test model provided by Dell US

尽管不像戴尔自己的13寸及15寸XPS机型一样有名,Latitude 7480从某种程度上来说是其有名的主流笔记本的商务款。这台外观出色的14英寸笔记本比起上一代更加轻薄,但制造质量毫无疑问的保持了高水准。外壳坚硬且制造准确,有着柔软的类肤质图层。屏幕亮度高,色彩准确,且没有反射的问题,所以户外用户无须担心烦人的反射问题。性能是顶级的,尽管部分CPU性能测试在短期内出现了轻微的性能下降。这台笔记本在同步基准测试中表现优异。电池续航时间足够一整天的使用,尽管充电速度偏慢。输入设备极为出色,我们认为它是现在市面上最好的笔记本键盘之一。

Latitude 7480 是一台高质量的稳固的商务本,但它伴随的线圈啸叫对它是个致命伤。

如果想要找到一个明显的缺点,那就是线圈啸叫,它在至少3英尺远的地方都能被听到而且看上去无论在任何负载条件下都会发生(但显然在待机状态下最为明显)。我们的确希望这只是我们这台测试样机的问题。但考虑到我们对Latitude 5480以及7280的测试中遇到了相同的测试问题,那么假设真实情况是这是一个广泛问题的话我们也不会惊讶。
