Overview

The LG OLED55G4SUB represents the 2024 apex of LG's consumer OLED lineup in the 55-inch class. The G4 series distinguishes itself from LG's more accessible OLED models through the combination of an OLED evo panel — which achieves higher peak brightness than standard OLED panels — and the a11 AI Processor 4K, which handles local brightness optimization, real-time upscaling from HD and SDR sources, and dynamic tone mapping for HDR content. The result is a display that not only achieves perfect blacks courtesy of self-emissive pixel technology but also competes meaningfully with high-end mini-LED displays in peak brightness, closing the one gap where OLED has historically lagged. Support for Dolby Vision, HDR10, and HLG means virtually every streaming service and content format delivers its best version of the image.

The 120Hz native refresh rate with HDMI 2.1 bandwidth and VRR support makes this television equally at home in a gaming setup as a cinema room — PS5, Xbox Series X, and PC users can drive 4K at 120fps with variable refresh, while ALLM automatically engages game mode when a console is detected. WebOS 24 is one of the more polished smart TV platforms available, and the Magic Remote's pointer control reduces the tedium of navigating large app grids. This bundle includes wall mount hardware and LG's Magic Remote, positioning the G4 as a gallery-style wall installation. For buyers who want the definitive consumer OLED experience at 55 inches — and value the bundled burn-in protection coverage for long-term peace of mind — the G4 makes a compelling, if premium, case for itself.

Pros & Cons

👍 Pros

  • OLED self-lit pixels deliver perfect blacks and infinite contrast — a fundamental image quality advantage over any LCD or LED-backlit panel at this size
  • 120Hz native refresh rate with VRR support makes fast motion, sports, and gaming smooth and judder-free without motion processing artifacts
  • a11 AI Processor 4K actively optimizes brightness, contrast, and upscaling in real time, producing noticeably better results with non-4K source content
  • Dolby Vision, HDR10, and HLG compatibility ensures broad source compatibility across streaming platforms, physical media, and broadcast content
  • Bundle includes two HDMI 2.0 cables and a 26-month protection plan with burn-in coverage — reducing immediate accessory cost and long-term risk

👎 Cons

  • OLED panels carry a non-zero burn-in risk for users who display static content (news, sports overlays, gaming HUDs) for extended daily hours
  • At 55 inches, 4K OLED commands a significant price premium over comparable LED/LCD alternatives in the same diagonal
  • webOS 24 ecosystem means LG's platform decisions govern app availability — niche apps not on LG's storefront require workarounds
  • The included wall mount makes this a gallery-oriented installation; the TV does not include a traditional stand in the listed bundle contents
  • HDMI 2.0 cables included in the bundle do not support HDMI 2.1 bandwidth — buyers pairing with 4K/120Hz or 8K sources should purchase HDMI 2.1 cables separately

Frequently Asked Questions

The G4 uses LG's newer OLED evo panel with the a11 AI Processor 4K, which delivers measurably higher peak brightness and more aggressive local dimming compared to the C4's a9 processor. In real-world use, the G4 pulls ahead in HDR highlight punch and color volume — noticeable in bright daytime scenes and HDR content. If picture quality is your priority and the price difference is within reach, the G4 is a meaningful step up.
The 4.2-channel built-in speaker system is genuinely usable for everyday TV watching — it handles dialogue clearly and provides wider soundstage than most flat-panel competitors. For immersive movie audio or music listening, a soundbar or home theater system will outperform it, but the built-in audio won't embarrass itself in a typical living room.
Yes — the G4 supports 4K at 120Hz via HDMI 2.1, making it a capable gaming and PC monitor for users who sit within comfortable viewing distance. NVIDIA and AMD GPU owners can leverage VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) for a smooth, low-latency desktop experience.
OLED burn-in risk is real but manageable for typical viewing habits. The G4's a11 processor includes automatic pixel refresh and panel care features that mitigate long-term retention. Displaying static content — like a news ticker or HUD — for many hours daily over months carries more risk. For varied viewing (streaming, gaming, movies), burn-in is rarely a practical issue. This bundle includes a 26-month protection plan that covers burn-in, which reduces the financial risk.
The G4 runs webOS 24, LG's mature smart TV platform. It supports all major streaming apps — Netflix, Disney+, Apple TV, Prime Video, YouTube, and more — alongside AirPlay 2, HomeKit, and Google Assistant integration. The Magic Remote with pointer control makes navigation noticeably more intuitive than directional-button-only remotes.
