| 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. » 67 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms). | ||

| 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. » 39 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (33.7 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 20830 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 20830 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 20830 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Pros
Cons
联想这次挽起了袖子，希望凭Flex 11 Chromebook在教育市场中一争高下。在它279美元的价钱背后的是所有用户可能期待的常见功能。它采用了低成本（同时绝不优雅）的ABS/碳素塑料机身，它提供了不错的坚固度，搭配橡胶边角也可以对坠落等意外情况提供一定的保护。它搭配了一块防溅水键盘和触控板，利用独立水流通道为内部组件提供保护。由于采用简洁的Chrome OS，它在运行中响应迅速，同时big.LITTLE芯片组和大容量电池的搭配带来了很长的续航时间。在这些之上，它的屏幕品质也十分不错（除了较低的分辨率），同时支持触控。
Flex 11 Chromebook在对教育市场的冲击中使出了一套强力组合拳：简洁可靠的性能表现，坚固的机身，长电池续航，和亲易近人的定价。不过，它的输入设备和连接性缺让人略感遗憾；外观设计也不是它的优势所在。
当然，由于价位不足300美元，它也有不少妥协之处。首先——我们知道你可能已经听厌了，不过我们不得不指出来——Chrome OS依然不能算是一个像是Windows一样得到广泛支持的全功能操作系统。对于安卓应用的支持会带来不小改善，不过依然离完整个人电脑体验很远。除此之外，它的输入设备最多只能算是一般。它的键盘键程短、反馈弱，而触控版的搭配按键可以说是我们用过最差的之一。作为一台11.6寸机型，它的重量和尺寸也都较大，不过可能大部分青少年可以接受这个限制。最后，它只提供了最基本的接口，仅两个USB接口（其中一个是C型接口，同时作为充电接口）和一个用于视频输出的HDMI接口。
不过，从整体上来看，Flex 11是一台十分值得推荐给需要此类设备且可以接受它的弱点的用户的设备。它没有特别的亮点，但是提供了完整的表现和较高的性价比。
