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
35 ms ... rise ↗ and fall ↘ combined↗ 8 ms rise
↘ 27 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 (21.6 ms).
       Response Time 50% Grey to 80% Grey
36 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 17 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 44 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (33.8 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 detected 1000 Hz ≤ 20 % brightness setting

The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1000 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 18034 (minimum: 5 - maximum: 3846000) Hz was measured.

戴尔XPS 12 9250是一款纤薄的12.5寸变形本。它搭载的英特尔酷睿 m7 6Y75处理器足够应付日常任务,它的热设计功率可以实现被动散热。它的固态硬盘读取速度超高,可以保证系统响应快速。3840x2160像素的高分辨率12.5寸屏幕带来了高对比度,优秀的色域覆盖和宽广的可视角度范围。它同时还作为输入设备支持多点触控。它的键盘底座与平板十分协调,键盘的打字噪音小,触控板响应准确。

第一眼看上去它是一台雅致的变形本,提供了非常有吸引力的技术参数。剩下的问题就是戴尔为它设定的价码可能有些高不可攀。

除此之外,它还是有一些让我们不太满意的地方。键盘底座提供的屏幕角度无法改变,可能无法满足各种使用情况的需要。尽管我们的测试机采用了英特尔酷睿m系列的最强处理器,它的性能却无法得到完全发挥。因此,搭配酷睿m3的微软 Surface Pro 4在一些情况下甚至更快。我们也希望它能有更长的电池续航。它的电池表现对于商务用途来说还有待改进。

它到底值不值得推荐呢——正在考虑购买这类设备的用户需要谨慎考虑它的弱点和优势。戴尔为这个配置机型贴上了高昂的1799欧元(约13259人民币)价码。这绝不算便宜,不过它是有4K屏幕的为数不多的12.5寸设备——如果这是你的选购标准的话。或许搭配较弱处理器的型号可能更值得参考,因为无论如何酷睿m7无法提供实际的性能。
