Acer TravelMate P648-M-757N 笔记本电脑简短评测

Name: Acer TravelMate P648-M-757N
Brand: Acer

均衡。 华硕带来了一台设计优良的14寸TravelMate，与来自惠普、戴尔和联想的设备相竞争。这台TravelMate在外观上与前代机型相同。不过，生产商为它搭配了最新硬件：Skylake，DDR4和Thunderbolt 3接口。百尺竿头更进一步，它值得称道的一大优点是出色的电池续航时间。

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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (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
25 ms ... rise ↗ and fall ↘ combined	↗ 7 ms rise
25 ms ... rise ↗ and fall ↘ combined	↘ 18 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 0.1 (minimum) to 240 (maximum) ms. » 55 % 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
44 ms ... rise ↗ and fall ↘ combined	↗ 16 ms rise
44 ms ... rise ↗ and fall ↘ combined	↘ 28 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).
