LG OLED55G4SUB OLED evo G4 55-Inch 4K Smart TV

Overview

Self-lit pixels switch on and off individually, so each one carries its own light instead of borrowing it from a backlight behind the screen. That is why the panel reaches deep black and stays thin enough to hang almost flush with the wall under the One Wall design. Brightness Booster Max magnifies those pixels for a picture that holds up in a lit room.

Picture quality leads here: self-lit pixels, a processor that upscales and tones each scene, and film modes tuned to the director's intent. The panel warranty covers years beyond the usual coverage, which matters because OLED is a long commitment. What it does not solve is placement. The One Wall design expects a wall, and the included base is shallow, so a deep media console or a corner may not suit it.

Who it's for

A household that watches a mix of films, streaming shows and games and wants the screen to disappear into the wall between sessions. The set also suits a bright room, since the panel pushes more light than earlier OLED generations. Buyers who need a deep, adjustable tabletop stand or who plan to move the TV between rooms should look elsewhere.

Pros and cons

Performance notes

Per-pixel dimming means contrast comes from each pixel switching off rather than a backlight zone fading, so dark scenes avoid the halo that edge-lit sets show. The processor handles upscaling and tone mapping per scene, which holds lower-resolution sources and HDR grades looking consistent. Motion is governed by the panel response time and the refresh rate working together, so fast camera pans and game frames stay clean.
