惠普 EliteBook 820 G3 亚笔记本电脑简短评测

Name: HP EliteBook 820 G3
Brand: HP

放下屏幕。 第三代惠普EliteBook 820是一台紧凑的12.5寸亚笔记本电脑，为商务环境设计。不过我们的测试机有些不平衡，尽管性能表现优秀，但它搭配了很差的TN屏幕。电流噪音也是这款小尺寸笔记本的问题之一。

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
29.2 ms ... rise ↗ and fall ↘ combined	↗ 12 ms rise
29.2 ms ... rise ↗ and fall ↘ combined	↘ 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 0.1 (minimum) to 240 (maximum) ms. » 76 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
58 ms ... rise ↗ and fall ↘ combined	↗ 24.8 ms rise
58 ms ... rise ↗ and fall ↘ combined	↘ 33.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 94 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 ms).

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 8774 (minimum: 5 - maximum: 343500) Hz was measured.

In review: HP EliteBook 820 G3. Test model courtesy of HP Germany.

太可惜了，惠普。这家生产商给我们带来的EliteBook 820 G3在一些方面表现非常优秀，但测试中给我们印象更深的是它的缺点。它最大的问题明显是屏幕。让人遗憾的是它目前只有高端机型搭配了全高清IPS屏幕。不过它的一些小问题也很烦人，除了在前代产品中已经存在的风扇噪音之外，这台测试机还会发出电流声，同时指点杆的按键有些太硬。

这些相对次要的问题让我们几乎忘记了它的优势，惠普赋予了它非常优秀的机身和连接性，可维护性以及出色的性能。这台设备在运行中可以保持清凉，电池续航也十分不错。除了我们所提到的问题外（至少TN屏幕应该得到改进），EliteBook 820 G3应该可以成为一台优异的亚笔记本电脑。不过，我们认为在这个价位上很难向用户推荐我们测试的这个型号。

新一代的EliteBook 820 G3受到了一些本可以避免的小问题的影响。如果可能的话，请尽量选择全高清IPS屏幕的型号。
