Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 962 Hz | ||
≤ 99 cd/m² brightness | |||
The display backlight flickers at 962 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 cd/m² and below. There should be no flickering or PWM above this brightness setting. The frequency of 962 Hz is quite high, so most users sensitive to PWM should not notice any flickering. Flickering occurs at relatively low brightness settings, so extended use at this brightness setting or lower can cause eyestrain. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17373 (minimum: 5 - maximum: 3846000) Hz was measured. |

Pros
Cons
联想Yoga Chromebook C630是一款功能强大的4K屏性能怪兽,事实证明Chrome OS对它来说太大材小用了。虽然C630是迄今为止功能最强大的Chrome OS笔记本电脑之一,但大部分功能都是性能过剩甚至是有不利影响。
特别是,与竞争对手相比,电池续航较差,与我们对Chromebook的期望相去甚远。此外,该设备可能是我们测试过的最不便携的Chromebook。这是15.6英寸翻转本的代价。对于这样一台针对有便携需求的用户的设备来说,C630显得过于笨重。
C630和竞争对手拉开距离。Pixelbook价格并不昂贵,并且在更紧凑的机身中提供了大部分细节。戴尔的Inspiron Chromebook 14占地面积略小,并以相同的价格保持了Yoga Chromebook C630的性能。 Inspiron还包括一个手写笔,并拥有我们在Chromebook上所见到的的最好的屏幕之一。
不过它还是有一些亮点的。首先,4K显示器看起来清晰而美观。此外,由于Chrome OS将来不可避免地要求更高的硬件,因此慷慨的RAM和存储选项将有能力“战未来”。考虑到谷歌在Chrome OS中与原生Android和Linux集成所取得的进步,这样的变化发生的时间可能不会太长,使得8 GB的RAM成为Chromebook的标准。
综合来说,联想Yoga Chromebook是一台称职的设备,但感觉有点大材小用。虽然4K显示屏,8 GB RAM和Core i5 CPU符合了市场的一切需求,但它们最终提供的功能远远超过其他高级Chromebook。而且,C630对于Chrome OS来说太过臃肿了。这个价位有更好的选择
