联想IdeaPad Duet 5Chromebook 回顾。OLED现在是超级实惠

比大多数副笔记本的显示效果好。

大多数廉价的Chromebook配备了平均或不合格的显示器,以保持低价。IdeaPad Duet 5设法包括一个AMOLED面板,以获得卓越的色彩和黑色水平,同时保持一个有竞争力的价格。
Tablet Chromebook Touchscreen ARM

超极本和游戏笔记本在其各自类别中的型号之间可能有很大差异,而Chromebooks之间的差异往往要小得多,特别是在显示质量方面。13.3英寸的联想IdeaPad Duet 5Chromebook 2-in-1是第一批包括1080p AMOLED触摸屏而不是通常的TN或IPS而不需要抬高价格的产品之一。假设价格相当接近,是否有任何理由考虑使用IPS替代品?

13.3英寸联想IdeaPad Duet 5可拆卸的竞争者包括其他Chromebooks,如 IdeaPad Flex 5, AcerChromebook Spin 713, 惠普Chromebook x2 11, 或 华硕Chromebook Flip CX5.然而,没有一个人有AMOLED选项。

案例

这款平板电脑本身的设计比大多数其他Chromebook ,尤其是它的边框更小,屏幕与身体的比例更高。不幸的是,该设备的弯曲甚至吱吱作响比我们最初预期的还要容易。因此,我们建议尽可能保持磁性后盖和键盘底座的连接,以提高设备的整体刚性,防止意外损坏。

当后盖和键盘底座都连接在一起时,整个系统的重量约为1.21公斤。

配件和保修

零售盒包括磁性后盖、键盘底座附件和USB-C交流适配器。标准的一年有限保修期适用。

输入设备

键盘

惠普Chromebook x2 11的键盘附件的最大问题之一是,它永远不会完全平放在桌子上,所以几乎每按一个键,整个甲板都会弯曲或摇晃。对联想来说,幸运的是,IdeaPad Duet 5的键盘附件没有出现同样的问题,可以获得更牢固、更均匀的打字体验。然而,它的按键仍然比大多数笔记本电脑的键盘要浅和软。我们希望在未来的版本中看到更多的背光按键。

触摸板

点击板比惠普Chromebook x2 11的点击板略小(10.5 x 6.2对11 x 6厘米)。反馈很响亮,但也比我们希望的更有弹性。有可能在点击板表面向下推而系统没有记录到点击,这使得拖放操作比需要的更困难。

显示

AMOLED触摸屏无疑是IdeaPad Duet 5的最佳方面。与IPS相比,AMOLED几乎总是提供卓越的黑白和灰度响应时间,更深更准确的颜色,更好的亮度均匀性,以及更高的黑度,以获得更生动的内容。宽广的色域和快速的响应时间特别值得注意,因为许多其他的Chromebook通常采用较便宜的面板,颜色明显较浅,并有明显的重影。这里的面板相对较亮,约为360尼特,不过也有配备更亮的IPS显示屏的Chromebook,如宏碁Chromebook Spin 713或HPChromebook x2 11。

不幸的是,脉宽调制存在于这里的所有亮度水平上,这意味着对屏幕闪烁敏感的用户可能要避免长时间使用IdeaPad Duet 5。

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
2.6 ms ... rise ↗ and fall ↘ combined↗ 1.2 ms rise
↘ 1.4 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 10 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
2.3 ms ... rise ↗ and fall ↘ combined↗ 1.1 ms rise
↘ 1.2 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 8 % of all devices are better.
This means that the measured response time is better than 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 detected 60.2 Hz ≤ 100 % brightness setting

The display backlight flickers at 60.2 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 60.2 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured.

当亮度为50%或更低时,PWM频率变为480.8 Hz

消耗功率

在桌面上闲置时,根据亮度水平、颜色和无线活动,耗电量在1瓦到7瓦之间。由于这是一个OLED面板,白色会比其他颜色 比其他颜色的耗电量大得多而IPS面板上的颜色在耗电方面则相对平等。因此,以暗色为主的网站可以帮助延长Duet 5的电池寿命。

日常浏览时,小型(约5.2×2.8×4.2厘米)30瓦USB-C交流适配器的耗电量约为9瓦,最高为12瓦。

全黑屏的最大亮度设置为0s至10s,全白屏的最大亮度设置为10s及以上。仅仅是显示全白的图像,系统就需要多出4W的功率。

电池寿命

虽然联想宣传的是15小时的电池寿命,但我们只能在150 nit的亮度(或设置11/16)下记录大约11小时的真实世界网络浏览。从空电到满电的充电速度令人失望,超过4小时,而大多数笔记本电脑的充电时间不到2小时。

如果你厌倦了屈从于不合格的显示器,或者需要从你的下一个Chromebook ,那么IdeaPad Duet 5为转换到AMOLED提供了强有力的论据。它的观看体验不仅仅是可测量的更好,而且与大多数基于IPS的Chromebook 相比,肉眼也有明显的改善。

然而,就最大亮度而言,宏碁Chromebook Spin 713和惠普Chromebook x2 11的显示屏比我们的联想更亮,在户外时更容易入眼。IPS面板也不太可能出现PWM或屏幕闪烁的情况。由于它们在子像素排列方面的优势,它们也只是比AMOLED稍微清晰一些,但在这样一个小的13.3英寸显示屏上,这在实践中是很难注意到的。

对IdeaPad Duet 5感兴趣的用户要记住,如果它的可拆卸盖子脱落,它在一定程度上很容易被扭曲和损坏。非常慢的充电速度对于经常旅行的人来说也是一个问题,而且缺乏一个集成的MicroSD读卡器限制了本地存储选项。

价格和可用性

联想IdeaPad Duet 5Chromebook ,现在可以在 亚马逊, 沃尔玛, 和百思买分别为429美元、469美元和449美元。亚马逊、沃尔玛和百思买的版本分别配有4GB内存和64GB eMMC,4GB内存和128GB eMMC,以及8GB内存和126GB eMMC。
