Display Response Times

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
29.6 ms ... rise ↗ and fall ↘ combined↗ 6.8 ms rise
↘ 22.8 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 72 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.8 ms).
       Response Time 50% Grey to 80% Grey
50.8 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 32 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 85 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.5 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9259 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Acer TravelMate P449-M-7407. Review unit courtesy of Acer.

宏碁TravelMate P449是“无所不能,便一无所精”的。它是一个全面的设备,涉猎甚广。它大小适合,机身体积小,重量轻,便于携带,但是屏幕仍然足够大,可用于多任务办公。机身看起来有专业而有吸引力。键盘看起来很不错,和性能足够用。显示屏提供高对比度和艳丽色彩。风扇仅在极端负载下才会发出噪声。温度管理良好,即使在满负荷条件下,设备仍保持低温。端口众多,有5个USB端口,2个显示器选项端口和一个以太网端口,电池足以支撑一整天的工作。

对于那些需要便携且续航持久的机器的用户来说,宏碁TravelMate P449是一个很好的选择。尽管它有一些缺点,如果预算有限,这将是一个不错的选择。

TravelMate做出了一些牺牲,以获得有竞争力的价格点。俊朗的外壳很薄,感觉很廉价,因此长期耐用性将是一个问题。触摸板不同步,而指纹读取器几乎没有用。屏幕昏暗,几乎不能在明亮的光线下使用。大多数连接端口都很慢或已经过时,而Skylake 处理器已过时,并且严重节流。

即便如此,宏碁TravelMate P449-M-7407仍然是1000美元以下商务本市场上的一个引人注目的选择。然而,联想 ThinkPad E470 的价格难以忽视。约720美元,E470提供更好的性能和质量,类似的续航时间,一个良好的IPS屏幕和一个独立显卡。对于130美元以上的价位,ThinkPad可以配备Kaby Lake 酷睿i7-7500U的处理器和16 GB的内存。请记住,这些机型不附带操作系统,只能在教育市场上获取。对比TravelMate,ThinkPad E470更值得推荐。但是,如果E470无法获取,P449是一个不错的备选方案。
