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 | ||
|---|---|---|
| 39.2 ms ... rise ↗ and fall ↘ combined | ↗ 22 ms rise |  |
| ↘ 17.2 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. » 97 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 52 ms ... rise ↗ and fall ↘ combined | ↗ 26 ms rise |  |
| ↘ 26 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. » 87 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 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 detected | 1250 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 1250 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 1250 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. | |||

- 只有12个月的保修
- 关上屏幕时发出吱吱声
联想通过新的ThinkPad E14继续发展E系列：较薄的机身从旧款ThinkPad E490汲取了很多设计灵感，并因此发挥了许多优势。其中之一：出色的ThinkPad输入设备。其他包括即使在负载下也具有良好的续航时间和较低的发热量/噪音水平。ThinkPad E14仍然可以升级，尤其是在存储方面。另外，由于增加了铝的使用，触感也得到了改善。
不幸的是，还有一些退步的地方：microSD卡插槽已被移除。 RAM的可升级性也受到限制：E14不再提供了两个SO-DIMM插槽和最多64 GB的双通道内存，而是提供了一个RAM插槽和最多32 GB的单通道内存。其他不利因素包括12个月的保修期和屏幕覆盖色域差的问题。令人担忧的是关闭屏幕时铰链区域发出的吱吱声–做工绝对不是完美的。
确实没有比老款更好：联想ThinkPad E14不必要地删除了某些功能。
总体而言，尽管存在缺陷，我们仍然推荐联想ThinkPad E14因为它仍然是一台坚固的ThinkPad笔记本电脑，尽管存在一些缺点-尽管我们确实认为它由于功能的缺失而不像前代ThinkPad E490那样吸引人。
