实测数据
性能表现
这台电视的核心是α5 AI Processor 4K Gen7芯片，它主要干两件事：一是让webOS 24系统跑得飞快，二是负责把非4K内容升频到接近4K的水平。实际观感上，流媒体内容的清晰度确实不错，但因为是直下式LED面板且没有局部调光，峰值亮度有限，HDR效果只能说是聊胜于无。HDR10和HLG的支持让它能正确识别高动态范围信号，但受限于面板素质，画面冲击力远不如那些亮度更高的竞争对手。
游戏方面，60Hz面板和ALLM自动低延迟模式是它的全部家当。没有HDMI 2.1接口，意味着4K 120Hz和VRR都与你无缘。对于Switch或者偶尔玩玩PS5的轻度玩家来说够用，但如果你是盯着帧数玩的硬核玩家，这台电视的38百分位游戏评分已经说明了一切。音频部分，20W的双声道扬声器表现中规中矩，46百分位的排名意味着它比一半的电视声音要好，但也就仅此而已，看大片还是建议外接个回音壁。

竞品对比
跟索尼BRAVIA 5 K55XR50比，LG的智能系统流畅度完胜，但索尼的画质调校和HDR映射明显更老道。海信U7系列75U75QG则是另一个维度的对手，它用更高的亮度和更好的游戏支持碾压UT75，但价格也贵上一截。TCL QM7K系列55QM7K在亮区和暗区细节上同样优势明显。简单说，UT75的对手都在画质上赢它，但它在智能体验和价格上扳回一城。如果你把电视当显示器用，那三星QN80F的亮度和色彩会好很多，但价格也翻了几倍。

价格
性价比分析
这台电视的价格跨度大得离谱，从240美元到13190美元都有。我们当然只讨论正常价格，也就是两三百美元这个区间。在这个价位，你得到的是一台智能系统顶级的50英寸4K电视。虽然画质和游戏性能不是它的强项，但如果你买电视90%的时间都在看Netflix和YouTube，那它的价值就体现出来了。注意看不同店铺的价格，差价可能够你再买个回音壁。

概述
LG UT75系列50UT7570PUB在我们数据库中的智能功能评分排到了前1%，这基本是现在你能买到的、最聪明的电视之一。webOS 24系统加上α5 AI处理器，让整个操作流畅得不像一台入门级电视。但别被智能光环完全迷惑，它的画质和游戏表现只能算中规中矩，在我们的测试中分别排在36和38百分位，属于够用但不出彩的水平。
常见问题
Q: 这台电视支持4K 120Hz游戏吗？
不支持。它只有60Hz面板和HDMI 2.0接口，游戏评分在我们数据库中排38百分位。ALLM可以保证低延迟，但高帧率游戏和VRR就别想了。
Q: HDR效果怎么样？
只能说有这个功能。它支持HDR10和HLG格式，但因为面板亮度不高且没有局部调光，实际HDR画面冲击力有限，HDR评分排在63百分位，属于能解码但显示效果一般的水平。
Q: 可以语音控制吗？
可以。它内置了Alexa，同时也支持Google Assistant和Apple AirPlay 2。智能功能评分99百分位，语音控制和智能家居联动体验都非常流畅。
不适合的人群
对画质有要求的电影发烧友和硬核游戏玩家应该直接跳过这台电视。36百分位的画质评分意味着它的亮度、对比度和色彩都只是入门水平，HDR内容看起来会比较平。38百分位的游戏评分也说明它完全不适合次世代主机玩家，没有HDMI 2.1和VRR，玩起来就是差点意思。如果你买电视主要是为了看蓝光原盘或者玩PS5大作，加钱上TCL QM7K或者海信U7系列会是更明智的选择。
最终评价
LG 50UT7570PUB是一台优点和缺点都极其分明的电视。它的智能系统是绝对的顶级水准，设置简单，日常使用极其省心。但它的画质和游戏性能也确实落后于同价位的部分竞品。如果你追求的是无脑好用、开机即看的流媒体体验，并且对画质没有极致要求，那这台电视很合适。但如果你对HDR观影或次世代游戏有一点点追求，那还是看看别的吧。
