戴尔 Inspiron 17 7778 变形本简短评测

巨型变形本。 一台17寸的变形本?为什么不行呢?喜欢Windows 10的平板模式的用户应该会对这个不太常见的组合十分满意。不过这台Inspiron同时也可以成为一台不错的传统办公设备——只有它的键盘相比同价位设备较弱。

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
22 ms ... rise ↗ and fall ↘ combined↗ 5 ms rise
↘ 17 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. » 44 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
36 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 22 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. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.9 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

戴尔的全新Inspiron 17 7778二合一笔记本电脑显然是一个不寻常的设备。变形本通常注重便携性,因此市场上常见的是尺寸更小更轻薄的设备。不过它的大尺寸并不一定会是个缺点,因为多种使用方式也会为传统的多媒体笔记本带来更多可能性,同时GeForce 940MX也可以让它有一定的游戏性能。它的机身品质完全可以令人满意,而屏幕也毫不逊色。在运行中,它的系统可以保持安静。不错的续航时间也应该可以让带着7778出门的用户十分欣喜。

除了屏幕转轴不够稳定之外,我们也对它的键盘质量略有微词,它应该很难满足打字较多的用户的需要。它的显卡在使用中会有降频现象,不过并不严重。测试编辑还发现它的触控屏幕在手指潮湿的情况下响应不太准确。

 

整体上,戴尔Inspiron 17 7778是一款多用途、设计时尚而性能全面的巨型变形本,它的缺点较少,而同时提供了丰富的使用模式。
