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 | ||
|---|---|---|
| 26 ms ... rise ↗ and fall ↘ combined | ↗ 5 ms rise |  |
| ↘ 21 ms fall | ||
| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 61 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.3 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 47 ms ... rise ↗ and fall ↘ combined | ↗ 16 ms rise |  |
| ↘ 31 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. » 80 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (31.7 ms). | ||
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 8170 (minimum: 5 - maximum: 343500) Hz was measured. | ||

+ 键盘品质
+ 背光键盘附带扬声器
+ 明亮的IPS触控屏幕
+ 后置RealSense相机
+ 不错的图片品质
+ 优秀的麦克风
+ 可调整支架
+ 不错的整体性能
+ 无噪音
Cons
- 机身有些小弱点
- 低游戏性能
- 低于平均的处理器速度
连接上时尚而不失坚固的键盘，Spectre x2可以有效的用作桌面笔记本电脑。USB C型接口被用作充电接口，它可以通过附带的转接埠连接现有的A型接口外置设备。平板背面的主相机可以拍摄非常不错的照片和视频。我们很久没有在Windows平板中感受到这一点了。另外，RealSense相机支持3D扫描——至少以后会。它可以用于测量结构深度，例如脸型。
Spectre x2也有一些还算可以接受的缺点。一些用户可能会怀念标准SD卡的读卡器。如果倾斜一点平板它的支架会错位。它的电池续航还不错，不过考虑到售价和酷睿M处理器，它应该实现7到8小时的上网时间而不只是测试结果的6小时。
仅仅达到Surface Pro Core M3水平的运算性能让我们十分失望。潜在用户应该考虑它的m3-6Y30版本(2x 900 MHz)，它应该在普通用途下提供更好的节能。它们的售价相同，不过较“弱”的机型搭配了LTE模组。如果需要性能的话，则需要考虑微软的Surface Pro 4酷睿i5/i7版本，它们也搭配了更快的NVMe固态硬盘。
实际上尺寸稍大的惠普 Spectre x360 13变形本搭配i5-6200U，性能更高，在我们的测试中得到了84%的分数。微软的Surface Book，Acer的Aspire R7-371T-52EL，联想的ThinkPad Yoga 12一级微软Surface Pro (i5/i7)都提供了相同水平的处理器性能。尽管需要高性能的用户可能需要考虑这些设备，不过也不一定就一定排除Spectre x2。它作为二合一设备十分实用。它的M7处理器的应用程序性能还有一定的竞争力。
