宏碁 Extensa 2520-59CD 笔记本电脑评测

Name: Acer Extensa 2520-59CD
Brand: Acer

非全速运行。 除了相当低的运行噪音之外，宏碁的这台15.6寸笔记本没有任何吸引人的地方。更加不幸的是，它所配备的Core i5处理器无法充分发挥它的计算性能。

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

1000 Hz

The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) .

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 8706 (minimum: 5 - maximum: 343500) Hz was measured.

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
31 ms ... rise ↗ and fall ↘ combined	↗ 14 ms rise
31 ms ... rise ↗ and fall ↘ combined	↘ 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 0.1 (minimum) to 240 (maximum) ms. » 82 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms).
↔ Response Time 50% Grey to 80% Grey
52 ms ... rise ↗ and fall ↘ combined	↗ 28 ms rise
52 ms ... rise ↗ and fall ↘ combined	↘ 24 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 (32.8 ms).

In review: Acer Extensa 2520-59CD. Test model courtesy of Notebooksbilliger.de

宏碁的Extensa 2520是一款基本型的15.6寸办公本。它所配备的处理器能够满足大部分用户的需求。但就像上面所说的，它的酷睿i5处理器没有办法发挥出它所有的性能，而是与酷睿 i3-6100U 的性能在同一水平线上。我们猜测我们拿到的或许是一台有故障的设备。无论这台笔记本运行在什么负载情况下它总是十分安静地运行而且基本上不会有过热现象的发生，它500G的机械硬盘提供了足够的存储空间。而且将机械硬盘换位固态硬盘是可行的，但这需要将外壳打开因为它并没有设置维修窗。整体上它的键盘给我们留下了很好的印象，而且续航能力十分出色。但另一方面，它的雾面屏幕却不尽人意，宏碁为它配备了一块亮度不足，对比度偏低且可视角度有限的屏幕。

宏碁设计的这台办公本十分安静且适合在家使用。

我们认为这台笔记本大约550欧元（约合618美金）的售价是最大的问题。在这个价位上，这台笔记本并不算是很便宜。想要节约资金的用户可以考虑型号为Extensa 2520-58BE的产品，它拥有和测试机相同的配置但是不带有Windows操作系统，大约比测试机便宜100欧元（约合112美金），即售价为450欧元（约合506美金）。购买一份二手Windows7 （售价低于10欧元约合11美金）并安装（宏碁提供了配套的驱动程序），而且当有需要时将他免费升级到Windows 10也是可能的（通过一些媒体创作工具）。
