结论--1000 美元以下级别的强劲竞争对手
LG Gram 笔记本电脑通常非常轻巧，显示屏清晰艳丽。而 Gram Book 15 摒弃了这些可圈可点之处，机身设计沉闷，IPS 显示屏似乎是 2010 年代早期最差的显示屏之一。对比度差，色彩浅，充其量只能提供一般的观看体验。与此同时，竞争对手的经济型笔记本电脑，如 华硕 VivoBook S15或 联想 IdeaPad Slim 5-15可以提供 120 Hz 的 OLED 显示屏，而后者至少可以提供完整的 sRGB 色彩。
除了令人失望的显示屏外，其他核心方面，如薄弱的设计、较浅的按键和较弱的扬声器，都使该机型成为一款不合格的多媒体或内容创作机器。
它的一些优点包括：酷睿 U 系列 CPU 带来的超长电池续航时间和超静音风扇，内存和固态硬盘的升级也相对简单。除此之外，Gram Book 15 与联想、戴尔或华硕的其他经济型中端产品相比，并没有令人信服的地方。
Pros
+ 支持可升级内存和最多两个 M.2 2280 PCIe4 固态硬盘
+ 电源效率高，电池寿命长
+ 相对较轻
+ 适当的端口选项
+ 风扇噪音小
Cons
- 键盘按键反馈微弱
- 低端显示屏色彩暗淡
- 塑料机身感觉廉价
- 不支持 Wi-Fi 7 或红外线
- 内置扬声器较弱

案例
机身从上到下基本上都是哑光塑料，以反映其经济实惠的价位。挠曲和吱吱嘎嘎的声音时有发生，但幸好都很轻微，无需担心。由于笔记本的光滑表面很容易吸附油脂和指纹，因此需要经常清洁。
交流
为节约成本，不支持 Wi-Fi 6E 和 Wi-Fi 7。

维护
底板由 9 颗十字螺丝固定，其中 4 颗隐藏在前部橡胶脚下，维修起来相对容易。
可持续性
制造商在生产过程中没有提及回收材料。
配件和保修
包装盒内除了交流适配器和文件外，没有其他附件。如果在美国购买，制造商通常提供一年有限保修。
输入设备
键程明显比传统的 ThinkPad T 系列甚至是华硕 VivoBook 等大多数经济型笔记本电脑。因此，按空格键、回车键或数字小键盘键时的反馈很弱，也不太令人满意。
显示屏
IPS 显示屏的刷新率为 60 Hz，色彩为亚 sRGB，是最基本的显示屏。遗憾的是，它的清晰度和鲜艳度远远不及大多数其他 Gram 笔记本电脑的显示屏，明显不适合用于严肃的内容创作目的。

显示器开箱后的校准效果很差，这在经济型笔记本电脑中是意料之中的。使用我们的 X-Rite 色差计进行校准后，平均灰度和色彩 DeltaE 值将分别从 5.2 和 6.78 大幅提高到 0.8 和 2.73。
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 | ||
|---|---|---|
| 26.6 ms ... rise ↗ and fall ↘ combined | ↗ 15.8 ms rise |  |
| ↘ 10.8 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. » 66 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.1 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 34 ms ... rise ↗ and fall ↘ combined | ↗ 16 ms rise |  |
| ↘ 18 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 (31.4 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 8002 (minimum: 5 - maximum: 343500) Hz was measured. | |||

压力测试
在启动 Prime95 压力测试时，CPU 会提升至 3.4 GHz 和 42 W，片刻后达到 82 C。随后，CPU 会稳定在 1.6 GHz、76 C 和 23 W，如下图所示，这表明 Turbo Boost 的可持续性很差。
当运行游戏等高负荷负载时，核心温度会徘徊在 70 C 左右，这比我们在去年的 HP Envy x360 15 上观察到的温度要低得多。 惠普 Envy x360 15.
