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

1064 Hz

≤ 90 % brightness setting

The display backlight flickers at 1064 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1064 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8747 (minimum: 5 - maximum: 343500) Hz was measured.

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
34.4 ms ... rise ↗ and fall ↘ combined	↗ 17.2 ms rise
34.4 ms ... rise ↗ and fall ↘ combined	↘ 17.2 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. » 91 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
48 ms ... rise ↗ and fall ↘ combined	↗ 24.4 ms rise
48 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 0.165 (minimum) to 636 (maximum) ms. » 81 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 ms).

In Review: Dell Precision 3520, courtesy of cyberport.de

Precision 3520有不少加分点。首先，它的屏幕色彩艳丽且明亮，十分适合工作所需。而它的电池续航作为工作站设备也十分优秀，可选的92瓦时电池将可以带来更加出色的表现。物理接口的数量也足够需要。机身和输入设备也可以达到商务设备的标准，不过也不算完美。

遗憾的是这台Precision在对于工作站来说最重要的方面表现欠佳：性能和噪音。对处理器的35瓦功耗限制可能已经会让一些用户感到不解，戴尔可能需要考虑设计一个更有效的散热系统，不过这对于一台实惠型工作站来说也不现实。我们怀疑如果搭配一颗性能较低的处理器会不会是更好的选择。在我们的压力测试中，这台设备的性能起伏较大，它的固件可能需要进一步调整更新。遗憾的是，对于风扇控制程序来说可能改善空间较小，即使是在低负载的情况下它也会持续运转。在基准测试后，用了很长时间风扇才渐渐开始减速。另外，3520还会发出电流声。

Precision 3520是一台性能不错的工作站设备，不过它还有不小的改进空间。

整体上，我们认为Precision 3520有不小的潜力。这台笔记本电脑性能十分优秀，同时具备优秀的性价比。但是，工作站设备依然十分昂贵。戴尔需要重新考虑他的设计，改善散热风扇系统和性能表现。如果它可以在这些方面得到改善，3520将会成为一台值得推荐的设备。
