LG OLED55 C4 Review (UK): The All-Round OLED to Beat
Quick verdict
The LG C4 is one of the best all-round TVs you can buy. Perfect OLED blacks, rich colour, Dolby Vision and some of the best gaming features on any TV make it brilliant for films, sport and consoles. Built-in sound is only average, so pair it with a soundbar if you can.
See the LG OLED55 C4 on Amazon UKLG's C-series OLEDs have been the go-to recommendation for years, and the 2024 C4 continues that run. The 55-inch model (OLED55C44LA in the UK) gets LG's α9 AI Processor Gen7, a brighter picture than before and support for up to 144Hz VRR gaming.
Who is it for?
The C4 is ideal for film and TV fans who watch in dimmer rooms, and for PS5, Xbox and PC gamers who want every modern gaming feature. 55 inches is a great size for most UK living rooms. If your room is very bright or your budget is tight, a mini-LED or LED TV may suit you better.

Picture quality
Because each OLED pixel makes its own light, the C4 can switch pixels off completely for perfect blacks and pin-sharp contrast. LG's Brightness Booster and the Gen7 processor improve HDR highlights over earlier C-series models, and Tech Advisor and The Telegraph both praised its HDR performance. Dolby Vision support means compatible Netflix and Disney+ content looks its best.
Gaming
This is where the C4 really stands out. All four HDMI ports are full HDMI 2.1, so you can connect a PS5, Xbox Series X and gaming PC without swapping cables. It supports 4K at 120Hz from consoles and VRR up to 144Hz from a PC, along with G-Sync, FreeSync Premium, ALLM and HGiG. The Game Optimiser dashboard puts the key settings in one place.
Smart features and sound
webOS 24 is responsive and includes all the major UK streaming apps, and LG promises up to five years of webOS upgrades. Dolby Atmos and AI Sound Pro are welcome, but reviewers consistently describe the built-in audio as average for a TV this good. A soundbar connected via eARC makes a big difference.
