LG Gram 17Z90P评论。灵活的轻量级，16:10的显示屏
LG Gram系列代表了特别轻和紧凑的笔记本电脑。LG Gram 17的重量为1350克（约3磅），稍微超出了我们的基准数据库。这款16:10格式的17英寸笔记本电脑在其低重量方面击败了许多明显更小的笔记本电脑。同时，LG Gram 17为办公室里的日常工作带来足够的性能。
与前代产品相比，处理器和设计得到了更新。与新的Tiger Lake 处理器一起，还有一些重要的更新，如PCIe 4和Thunderbolt 4。
用于办公和日常任务的笔记本电脑在这种尺寸和级别中是罕见的。因此，作为比较设备，我们必须使用更重的 联想V17-IIL，以及华硕VivoBook 17，以及Acer Aspire 5 A517，以及 惠普17.

外壳 - 镁制的轻金属结构
LG Gram的设计保持非常简单。在光滑的表面和边缘几乎没有任何东西可以吸引你的目光。与前代产品相比，这款笔记本电脑的边缘略显尖锐。每个圆角的半径被大大减少。同时，连接处也被稍微移动。
乍一看，你可能会认为这个箱子是由塑料制成的。然而，实际上该材料由漆面镁合金组成。显示屏可以打开到140度角，大部分都是用一只手。铰链很结实，显示屏不会晃动。
尽管该设备总体上显示出很高的工艺质量，既没有缝隙也没有尖锐的边缘，但当把LG Gram 17拿在手里时，不幸的是它没有提供高质量的感觉。轻金属结构主要在笔记本电脑的稳定性方面要求其付出代价。显示屏的盖子和底座非常灵活，很容易被翘起。如果笔记本电脑没有放在一个平坦的表面上，甚至可能发生它记录了非故意的鼠标点击。然而，由于采用了镁合金，这个灵活的设备不会被永久地翘起来。
在重量方面，LG Gram的重量为1353克（约3磅），没有竞争对手。此外，对于一个17英寸的设备来说，这款笔记本电脑也非常纤薄。与上一代产品相比，这款笔记本电脑的尺寸没有太大变化。
连接设备 - 现在有了Thunderbolt 4
与前代产品相比，现在的笔记本电脑只能使用USB-C电源传输进行充电。这意味着，目前的设备少了一个USB供你使用，除非你添加额外的硬件。然而，这款笔记本电脑在右侧提供了两个USB Type-C端口，带有Thunderbolt 4和PowerDelivery。这将允许你用相应的扩展坞增加端口。左侧有两个快速USB Type-A端口和microSD读卡器。
所有连接的位置都是经过深思熟虑的。它们之间的距离是足够的，所以它们不会互相妨碍，而且它们被放置在后面足够远的地方，防止在使用鼠标时产生障碍。
读卡器
使用我们的AV PRO microSD 128 GB V60参考存储卡，LG Gram的microSD读卡器分别达到了90和80.2 MB/s的良好读取和写入率。显然，LG没有在Gram 17中找到足够的空间来容纳一个完整的SD卡插槽。

沟通
英特尔Wi-Fi 6 AX201模块支持通过WLAN-AX和蓝牙5的连接。在最佳条件下，可能的上升和下载速度是平均水平。然而，你也可以使用两个雷电4端口中的一个来连接更快的网络适配器。

网络摄像头
LG Gram的0.9MP网络摄像头提供了当前笔记本电脑的典型图像质量。尽管图像质量至少比前代产品好，但你还是应该使用外部网络摄像头进行视频会议。

安全问题
凭借目前的英特尔i5处理器，该笔记本电脑提供了Windows 11所需的所有TPM 2.0和SecureBoot功能。此外，LG Gram 17提供了一个集成在电源键上的指纹识别器。在笔记本电脑的右侧还有一个用于电缆锁的插槽。
辅料
除了充电器和通常的文件，我们的LG Gram 17的盒子里还包含一个硅胶键盘盖，让你保护键盘免受灰尘、污垢或飞溅的影响。然而，制造商对包装内容的描述中没有列出这一点。
维护
LG Gram 17的所有外壳螺丝都隐藏在胶合的盖子或橡胶脚下面。这并没有使笔记本电脑特别便于维护，我们无法在不造成损坏的情况下拆除我们测试装置的大橡胶脚和塑料盖。现在的大橡胶脚是用强大的胶水固定的，当你试图移除它们时，它们开始撕裂。为了避免损坏借出的设备，我们因此没有打开它。 根据HWinfo的说法，工作存储器是焊接的。AX201 WLAN模块在这里也是焊接的版本。这意味着，除了更换固态硬盘和清洁机箱内的风扇外，几乎没有任何维护选项。据LG称，该设备中还有第二个M.2插槽，允许你扩展存储。
担保
LG提供24个月的保修。LG不提供任何额外的保修延期或保险选项。
输入设备 - 一个带照明的全键盘
键盘
LG Gram 17的大型照明100%尺寸键盘在打字时相当舒适。与前代产品相比，按键感觉不那么松软，而且有一个更明显的压力点。然而，我们再次注意到键盘的轻质结构，因为即使只施加适度的压力，它也很容易弯曲。
触摸板
轻质结构在LG Gram 17的大型触摸板上也很明显。虽然触摸板在固定和水平的表面上可以完美地工作，但当笔记本电脑轻度扭曲时，它可能会出现非预期的输入。
显示 - 16:10格式的2560p分辨率
LG笔记本电脑能够凭借明亮的IPS显示屏获得分数。平均323cd/m²的亮度在电池运行中几乎没有下降。虽然951:1的对比度值略低，但该面板在分辨率（2560 x 1600像素，178PPI）和良好的色彩再现方面显示了其优势。该显示器几乎再现了完整的DisplayP3色彩空间。所有这一切都使人能够舒适地阅读和使用该显示器。
几乎没有任何明显的屏幕出血现象，我们的相机图像只有在使用相应的曝光设置时才会显示。

色彩空间覆盖率
LG Gram 17几乎完全再现了DisplayP3色彩空间，这通常用于电影。从主观上讲，该面板的黑色还原度也很好。这两个因素结合在一起，应该能确保良好的电影再现。此外，DisplayP3色彩空间的色彩也只显示出很小的偏差。然而，LG Gram 17在交付状态下被配置为sRGB配置文件。
在办公室使用时，LG Gram 17的屏幕上已经可以看到外壳和周围环境的反射，而在户外，它们甚至会成为一种障碍。在阳光直射下，你只能从正确的视角阅读显示屏。
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 | ||

| 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. » 40 % of all devices are better.

This means that the measured response time is worse than the average of all tested devices (32.8 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||
IPS面板提供了一个高视角的稳定性。从侧面看几乎没有任何明显的颜色变化。然而，由于高度反射的显示表面，显示屏不能总是被轻易读取。周围环境和设备本身的反射会阻碍显示屏的可读性，否则就是好事。
性能 - 一台反应迅速的笔记本电脑
配备i5处理器的LG Gram 17很适合办公和互联网应用，这也应该使它适合许多消费者和专业应用。 另一方面，这款笔记本电脑只能在有限程度上用于3D应用和游戏。除了我们在这里测试的配备i5处理器和16GB内存的版本外，还有一个配备英特尔i7处理器的版本。然而，在前代产品中，与i5相比，i7只带来很小的性能优势。
处理器
的英特尔酷睿i5-1135G7于2020年9月推出，是一款适用于薄型笔记本电脑的高效四核处理器。你主要在13至15英寸显示屏的相当小的笔记本电脑中找到这种处理器。该SoC只需少量冷却就可以运行，而且主要是被动冷却。在LG Gram 17中，中度负载的PL1 TDP被配置为平均25瓦。然而，冷却系统无法将处理器持续维持在这一水平，因此，在某些情况下，PL1的TDP在较长的负载下又被降低了。在高性能模式下，PL1开始时的功率为28瓦，但在此也会迅速降低。重启后，性能总是被重置到中等水平。
该处理器也很难使用60瓦的提升性能（PL2）。在30分钟的Cinebench循环中，在最初的运行后性能明显下降。

系统性能
总的来说，LG Gram 17在日常使用中显得非常灵敏，尽管硬件并不是为最高性能设计的。LG控制中心提供三个性能级别来调整系统性能。以下所有的基准测试都是在高性能模式下运行的。当这种性能模式被激活时，控制中心会显示一个警告，即较高的温度发展可能会减少电池和CPU的寿命。然而，压力测试中的温度值并没有显示任何特别高的温度。
总之，如果考虑到笔记本电脑的低体积和重量，PC Mark 10基准测试的结果是相当好的。在实践中，这台笔记本电脑还可以让你完成一些工作。即使Cybex公司预装的图像和视频处理应用程序接近LG笔记本电脑的性能极限，它们在大多数时候也能顺利运行。这台笔记本电脑在轻松处理互联网浏览器和办公应用程序方面没有问题。

DPC延迟
虽然确定的DPC延迟不是很好，但它们与我们过去几个月的观察相吻合，微软的内核模式驱动在延迟方面不断产生问题。相应的驱动程序更新可以显著改变延迟。在YouTube再现我们的4k60测试视频时，所有的帧都能正确显示。

笔记本电脑的最高表面温度约为44°C（111°F），携带或触摸都不会太热。 掌托始终保持舒适的温度。
压力测试表明，笔记本电脑在较长时间的负载下有一个排放热量的问题。在压力测试中，PL1被电源控制反复调整。这在许多测量值中引起了一个特征性的波浪模式。

LG Gram 17的扬声器出乎意料地好，能产生相当可接受的声谱。这台笔记本电脑只是缺乏强有力的低音。需要注意的是，扬声器是朝下的，所以笔记本电脑放置的表面结构会对音质产生明显的影响。对那些音质不足的人来说，还可以通过3.5毫米音频端口或蓝牙连接耳机或外部扬声器。

LG Gram 17的功耗在较长的负载下会有所下降，只是在之后又会增加。这再次说明了散热的问题。处理器性能的提高和降低也造成了耗电量的上升和下降。性能曲线调整良好的笔记本电脑应该尽可能地保持恒定。然而，也有可能冷却和CPU的性能在一段时间内仍会调整，因为新设备最初经常测试其性能极限。

Pros
+ 重量非常轻
+ 镁合金外壳
+ 考虑到显示屏的尺寸，结构紧凑
+ 明亮的16:10显示屏
+ 存储空间可扩展
+ 表面温度低
+ 非常安静
+ 雷电4
Cons
- 箱子的硬度低
- 反射性显示
- 难以甚至无法打开
- 工作存储器和WLAN模块无法更换
- 昂贵的镁质结构导致价格上涨
结论 - LG Gram笔记本电脑是非凡的
LG Gram 17是一款漂亮而朴实的设备，在移动性方面没有任何同行。纤细轻盈的结构确实让人心动，但同时也带来了相对较高的购买价格。对于性能级别的办公设备来说，这款笔记本电脑的性能还算不错。不过，这款笔记本电脑的价格水平更属于入门级游戏笔记本电脑的范围。
如果随身行李中的每一克都很重要，那么LG Gram设备是绕不开的。此外，80瓦时的电池保证了电池的寿命，至少可以撑过一个工作日。所用硬件的性能对于办公室的日常工作来说是绰绰有余的。
电池可以轻松维持一整天。
显示屏以良好的色彩再现和较高的DisplayP3色彩空间覆盖率而大放异彩。不幸的是，你也会在17英寸笔记本电脑非常光亮的反射表面上看到各种闪亮的反射，这也会稍微限制笔记本电脑的移动性。然而，你仍然可以使用这种显示器轻松工作。
