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
50 ms ... rise ↗ and fall ↘ combined	↗ 12 ms rise
50 ms ... rise ↗ and fall ↘ combined	↘ 38 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. » 99 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
64 ms ... rise ↗ and fall ↘ combined	↗ 27 ms rise
64 ms ... rise ↗ and fall ↘ combined	↘ 37 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 97 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 ms).

In review: Dell XPS 15 9550 (Core i7, FHD). Test model provided by Dell US.

尽管它在推出之时给我们带来了不小的麻烦，XPS 15 2016更新在各方面都有所进步，特别是在显卡、尺寸、重量等方面。它的84瓦时电池在测试中表现惊人，而系统也可以在使用中保持安静清凉。

它的屏幕在低亮度（30%－40%以下）时通过闪烁调节背光亮度，这仍然是全高清屏幕机型的一个问题。另外，这块全高清屏幕几乎完全覆盖了sRGB色域，而4K屏幕型号提供了对AdobeRGB色域的覆盖。这两点应该可以说服创作艺术家选择4K屏幕机型，即使是对高分辨率不感兴趣。

它的更大电池容量占用了第二块硬盘的空间，不过不一定所有地区都会销售这样的机型。电池容量较小的机型可能会对希望把XPS 15用做多媒体和游戏笔记本的用户更有意义。

更大的屏幕，更小的尺寸，显卡的强劲性能让最新的XPS 15成为旅行、游戏、工作的理想选择。它侧重于家用，尽管屏幕色彩还原优秀，但缺少商务功能和一些接口。
