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
27.2 ms ... rise ↗ and fall ↘ combined↗ 10 ms rise
↘ 17.2 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. » 55 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.7 ms).
       Response Time 50% Grey to 80% Grey
47.6 ms ... rise ↗ and fall ↘ combined↗ 24.4 ms rise
↘ 23.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (42.8 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: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6668 (minimum: 43 - maximum: 142900) Hz was measured.

戴尔Vostro 15是一台不错的办公笔记本电脑。相比售价更昂贵的商务笔记本电脑来说它有不少不足之处,而这也不算是个新闻。但是,它并没有让人望而却步的严重问题。当然,全高清TN屏幕在色彩还原上表现较差,整体色彩偏蓝,但这对于办公用途(收发邮件,电子表格,简报,视频会议等)来说并不算是太大的问题。我们测试过的机型中也还有可视角度范围表现更差的。

它还有一些其他的缺点,比如平庸的输入设备,较慢的无线连接速度,安全功能的缺乏和较差的扬声器。不过其中有一些可以通过可选升级得到改进(键盘背光,指纹感应器,其他无线模组)。

戴尔Vostro 15是一台实惠型的办公笔记本电脑,它提供了不错的性能和品质优秀的机身。一块可选的IPS屏幕可能会让它更有竞争力。

我们十分喜欢它的优秀性能,安静的运行和美观机身,这些都优于大部分入门级设备。Vostro 15在坚固度上也不逊于很多更贵的设备。我们十分希望它能够搭配更高品质的键盘和一块IPS屏幕。

惠普 ProBook 450 G4宏碁 TravelMate P259都搭配了更差的屏幕。我们目前正在测试最新的联想 ThinkPad E570,初步来看搭配全高清IPS屏幕的这款设备可能是它们的强劲对手。
