👍 很多从等离子时代过来的老烧都对 G4 的黑位和立体感赞不绝口,觉得这是最接近等离子的升级体验。
👍 不少用户提到电视运行温度很低,跟以前那些发热严重的 OLED 完全不一样,挂墙很安心。
👎 一个反复出现的抱怨是 LG 的客服形同虚设,产品出问题后的售后体验非常糟糕。

实测数据

性能表现

最让人惊喜的是它的游戏表现。0.1ms 的响应时间配合 120Hz 原生刷新率,加上四个满血的 HDMI 2.1 接口,同时支持 G-Sync 和 FreeSync Premium,这基本就是一台伪装成电视的顶级电竞显示器。在我们的数据库里,它的游戏和连接性都排进了前 2%,属于绝对的顶尖水准。音频部分也出乎意料,60W 的 4.2 声道系统听起来比大多数超薄电视要饱满得多,杜比全景声的环绕感是实打实的。

竞品对比

跟索尼的 BRAVIA XR A95L 比,G4 在游戏响应和接口配置上明显更激进,而索尼的优势在于更准确的电影色彩和更干净的画面处理。如果你一半时间玩游戏,选 G4 没错。要是你纯看电影,索尼的画面会更有质感。至于三星的 Neo QLED QN900F,亮度确实能飙得更高,但在黑位和可视角度上,还是被 G4 的 OLED 按在地上摩擦。

价格

性价比分析

这台电视在不同渠道的价格跨度很大,从 1417 美元到 2766 美元都有。如果你能找到 1800 美元以内的好价,那它的性价比就相当能打,尤其是考虑到它自带的音响效果。但要是你原价入手,那就有点冤大头了,毕竟同门的 C4 系列便宜不少,核心画质差距并没有价格差那么大。

概述

LG G4 就是那种让你关灯看片时会忍不住笑出声的电视。它最核心的亮点是那块带亮度增强技术的 OLED evo 面板,结合完美的黑位和无限的对比度,画面立体感直接拉满。简单说,如果你追求的是电影和游戏里的极致视觉冲击,这台 55 寸的 G4 是目前市面上最接近正确答案的选择之一。

常见问题

Q: G4 和 C4 到底差在哪,值得多花那个钱吗?

主要差在亮度和设计上。G4 有亮度增强技术,在明亮房间里看 HDR 内容会更通透,而且它自带 60W 音响,壁挂效果也更贴墙。如果你主要关灯看片,C4 性价比更高;但如果你客厅光线足,又不想额外买回音壁,G4 多出来的钱就花得值。

Q: 这台电视玩游戏真的感觉不到延迟吗?

真的感觉不到。0.1ms 的响应时间已经快过人眼感知的极限了,加上 120Hz 和满血 HDMI 2.1,玩 PS5 或者接 PC 跑 4K 高刷都丝般顺滑。放心,它不会拖你后腿。

Q: 烧屏问题现在解决了吗?

LG 这几代 OLED 在防烧屏上已经做了很多优化,比如像素清理和屏幕位移。正常混合内容使用,看几小时电影玩几小时游戏,用个五六年问题不大。但你要是整天只盯着一个新闻台看,那还是去买液晶吧。

不适合的人群

如果你只是买来在明亮的客厅里白天看新闻和肥皂剧,这台 G4 就太浪费了。它的强项是暗场和 HDR 游戏,普通有线电视内容反而会暴露低码率信号的缺陷。这种情况下去买一台好的 Mini-LED 电视,比如索尼的 X90L 系列,你会更开心,还能省下一大笔钱。

最终评价

LG G4 是一台为游戏玩家和电影发烧友打造的旗舰 OLED,它在亮度和音响上的升级让它不再是那个"只能在全黑房间看"的娇贵玩具。只要你能避开首发原价,并且对 webOS 的广告有点心理准备,这台电视在未来几年都会让你看得很爽。
