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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8156 (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
20 ms ... rise ↗ and fall ↘ combined	↗ 6 ms rise
20 ms ... rise ↗ and fall ↘ combined	↘ 14 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 42 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (20.3 ms).
↔ Response Time 50% Grey to 80% Grey
37 ms ... rise ↗ and fall ↘ combined	↗ 16 ms rise
37 ms ... rise ↗ and fall ↘ combined	↘ 21 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. » 52 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (31.7 ms).

In review: Trekstor SurfTab duo W3. Test model courtesy of Trekstor Germany

Trekstor的SurfTab Duo W3是一款11.6英寸的Windows变形本，为基础办公与了网络应用而设计。这款设备运行时几乎不会发热且安静。然而，有一种从内部发出的电流声时常可以听见。这款设备并没有超大的存储空间。在32GB的机身存储中，仅有17.6GB可用。由于Windows 10在大的系统更新时需要10GB的空闲内存，所以7GB是实际可用最大存储空间大小。

键盘扩展坞整体上给我们留下了很好的印象。键盘本身很合适频繁的打字操作。Trekstor可能在它的产品线上为小学生和其他学生提供了一台用于打字和浏览网页的设备。但很不幸的是它在很关键的一个项目上表现得并不好：电池续航能力。这台变形本在Wi-Fi测试中仅有不到5小时的续航时间，这对于一整天在学校或大学的使用来说太短了。但在另一方面，屏幕的广视角及高对比度令我们满意，虽然亮度过低。
