LG OLED55B5PCA 55" OLED AI B5 4K Smart TV Review

Al****e 10/05/2025

Bought this for my PS5 and it's a game changer. The 120Hz with VRR is incredibly smooth, no screen tearing at all. Input lag is non-existent. The 4K visuals and Dolby Vision for Gaming make everything pop. A must-buy for gamers.

Mr. Leung 15/01/2025

Picture quality is amazing for an OLED at this price point, great value. However, the built-in 20W speakers are quite weak. You'll definitely need a soundbar for a better audio experience. Also, only Level 4 energy efficiency.

Mi*****k 22/11/2024

OLED個純黑真係無得輸,睇戲嗰陣啲暗位細節好清楚,contrast好勁!用Filmmaker Mode睇Netflix,個感覺完全唔同晒,好有戲院vibe。BBE送貨師傅好準時有禮。

Ca******e 08/03/2025

個Magic Remote好好用,小朋友都識用個碌碌同語音自己搵卡通睇。webOS個interface都好順,轉app好快。送貨連安裝一次過搞掂,好方便!

T. C. Ng 19/02/2025

Excellent 4K upscaling with the a8 processor. Even 1080p content looks crisp. Great connectivity with 4 HDMI 2.1 ports.

K. Y. Mak 01/12/2024

The AirPlay integration is seamless. Works perfectly with my iPhone and MacBook. Super convenient.
