Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 531 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 531 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 531 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pros
Cons
商务变形本的选择并不简单。总体来说，ThinkPad Yoga 370以及EliteBook X360是两台出色的竞品。而戴尔 Latitude 5289是一台有趣的竞品。这台测试样机最大的优势在于其电池续航时间。由于低功耗及超大容量电池，Latitude是这个方面最强的笔记本。坚固的外壳以及舒适键盘都值得考虑。得益于其搭载的ULC CPU，Latitude 5289的散热风扇能够很安静的运行。接口的选择符合它的商务定位。接下来我们会看看它的缺点。
超过1000美元的设备显然应该带有其竞品都带有的Thunderbolt 3接口。散热风扇的确是不经常运行，但戴尔并没能成功去掉烦人的高频啸叫。键盘不错，但是触摸板并没有给我们留下很深的印象，特别是当和来自惠普和联想的竞品相比，戴尔所选择的触摸板并不出色。不像联想或惠普，戴尔依旧选择了12.5寸的屏幕尺寸。这可以成为一个有点亦或是缺点，更少的工作空间和更轻的重量。12.5寸屏幕的一个通病是色域覆盖不佳。再者，漏光现象十分严重。但最少它的亮度能够支持户外使用。
戴尔带来了一台不错的变形本，它超长的电池续航时间特别吸引人。但它依旧很难在这个竞争激烈的市场上生存下来，而且戴尔的确在设计上犯了一些错误。
Latitude 5289事实上是一台不错的变形本。如果你在寻找一台拥有最长续航时间的变形本，那么它将成为一台值得推荐的设备。但是，它的竞品。ThinkPad Yoga 370和EliteBook X360也有着它们的强项。Latitude的入门机型号的确更便宜，但也仅提供更糟糕的仅仅只有4GB板载内存的配置。总体上来说，Latitude将很难跟它的竞品竞争。如果它有一块更好的13.3寸屏幕和改进的触摸板，也许能够打败它的竞品。就算它有着极出色的电池续航时间，它依旧只能排到第三名，特别是当考虑到联想和惠普的竞品续航时间也不差的情况下。
