宏碁 TravelMate P249-M-5452 (Core i5, 全高清) 笔记本电脑简短评测

Name: Acer TravelMate P249-M-5452
Brand: Acer

入门级商务伴侣。 这台14寸的宏碁设备有不少优势：它易于升级维护，提供了优秀的电池续航、高速固态硬盘和可靠的键盘。它的屏幕是仅有的弱点：一块可视角度较差的TN面板。

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

50 Hz

≤ 10 % brightness setting

The display backlight flickers at 50 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 50 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8719 (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
16 ms ... rise ↗ and fall ↘ combined	↗ 10 ms rise
16 ms ... rise ↗ and fall ↘ combined	↘ 6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 33 % of all devices are better. This means that the measured response time is better than the average of all tested devices (20.9 ms).
↔ Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined	↗ 23 ms rise
44 ms ... rise ↗ and fall ↘ combined	↘ 21 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. » 71 % 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 TravelMate P249-M-5452. Test model provided by Acer Germany.

宏碁为入门上午用户带来了TravelMate P249-M。它的定位侧重企业、自由职业者和学生用户，但没有提供如指纹感应器、拓展坞和LTE模组等常见的商务功能。它的处理器具备足够日常使用的性能，笔记本电脑在运行中十分安静，几乎不会变烫。一块高速固态硬盘保证了系统的迅捷响应，而用户也可以通过维护底盖方便地升级更换固态硬盘。他的电池续航和输入设备也都十分优秀。生产商更是为它提供了三年的质保。它最明显的缺点在于宏碁选择的TN屏幕面板，它的对比度还不错，但是亮度和可视角度范围都十分有限。
