The LG C4 OLED greets you with that familiar ultra-thin slab of glass and metal, but the picture that flares up in a dark living room is a little brighter and a touch more controlled than last year’s C3.

What defines the C4 update

LG positions the C4 OLED as its core 2024/2025 4K OLED TV, sitting just below the flagship G4 but above the entry B4 range in features and price. Official LG product page Product chief Park Hye-jin describes the C line internally as the “OLED for almost everyone” in Korean press statements.

The C4 keeps the flat 4K OLED panel with 120 Hz refresh rate and four full-bandwidth HDMI 2.1 inputs, a spec that still makes it attractive for owners of both PlayStation 5 and Xbox Series X.

Brighter panel and gaming tweaks

On the headline 55-inch and 65-inch sizes, LG uses its newer OLED panel with improved brightness, giving the C4 a measured peak around 1,300 nits in small HDR highlights according to early lab tests.

For gamers, LG’s Game Optimizer menu returns with support for 4K 120 Hz, variable refresh rate (VRR) and AMD FreeSync, plus NVIDIA G-Sync compatibility on PCs. Input lag stays in the single-digit millisecond range, so camera pans in fast shooters feel immediate rather than smeared.

Design, sound and everyday feel

Up close, the C4’s brushed metal stand feels robust when you nudge it, and the gently textured rear panel avoids fingerprint smears. The TV is still razor-thin at the top, so mounting it low on a wall creates that “window into the scene” effect in a dark room.

Sound is handled by an integrated 2.2-channel speaker system with virtual 9.1.2-channel processing, which tries to throw dialogue towards the center while lifting effects above the screen. LG’s AI Sound Pro mode can make voices clearer at low volume, though dedicated soundbars still outclass it for cinematic bass.

webOS 24, apps and smart control

On the software side, the C4 runs LG’s webOS 24 platform with a more streamlined home screen and user profiles that remember each person’s app layout and recommendations. The responsiveness when scrolling through apps feels smooth, and major services from Netflix to Apple TV+ are present at launch.

Product manager Kim Seung-ho has highlighted webOS 24’s update promise, with LG stating that supported models will receive feature updates for several years, which matters for buyers who keep a TV for a long time. The familiar Magic Remote still lets you point and click, or bark simple commands into the microphone when your hands are busy.

Where it fits in LG’s lineup

Within LG’s OLED family, the C4 remains the all-rounder that many retailers push as the “sensible sweet spot” between the brighter, pricier G4 and the more stripped-down B4. For most living rooms it delivers enough brightness without the price premium of the flagship series.

Pricing in Europe for the 55-inch model typically starts around 1,899 euros at launch, with street prices already sliding below that level at large online retailers. In South Korea and North America, local promotions often bundle extended warranties or soundbars instead of aggressive list-price cuts.

Context for investors and listing

For LG Electronics, OLED TVs like the C4 are still a strategic showcase for panel technology and a key contributor to its Home Entertainment division. The segment has faced pressure from cheaper Mini-LED LCD rivals, but OLED remains a margin anchor in premium sizes.

LG Electronics shares (ISIN KR7066570003) trade on the Korea Exchange in Seoul, where the share price reflects expectations around TV demand, appliance margins and newer bets in automotive and components.
