Overview

The LG 65-inch OLED B4 Series delivers the stunning picture quality that has made OLED the display technology of choice for home theater enthusiasts and gamers alike. Each of the TV's 8.3 million self-lit pixels turns on and off independently, producing perfect blacks, infinite contrast, and vivid colors that LCD-based displays simply cannot match. Powering the experience is LG's Alpha 8 AI Processor 4K Gen2, which uses artificial intelligence to analyze content in real time and optimize picture sharpness, color accuracy, and audio output scene by scene. Support for Dolby Vision and Dolby Atmos rounds out the cinematic experience with enhanced dynamic range and immersive spatial sound.

For gamers, the B4 is well equipped with a 120Hz refresh rate, NVIDIA G-Sync compatibility, AMD FreeSync Premium certification, and VRR support — delivering smooth, low-latency gameplay on PlayStation 5, Xbox Series X, and gaming PCs. The webOS 24 smart platform provides quick access to all major streaming services along with LG Channels for free content, and built-in Bluetooth and Wi-Fi keep connectivity simple. As a renewed model backed by the Amazon Renewed Guarantee, this TV brings LG's OLED performance to a lower price point, making it an appealing option for buyers who want premium picture quality without paying full retail.

Pros & Cons

👍 Pros

  • 120Hz refresh rate with G-Sync, FreeSync Premium, and VRR make it a capable display for current-gen gaming

👎 Cons

  • As a renewed unit, the TV may have minor cosmetic imperfections and its panel has prior usage hours
  • The B4 is LG's entry-level OLED line, so it uses the less powerful Alpha 8 processor rather than the Alpha 11 found in higher-tier models
  • OLED panels carry some risk of permanent burn-in with prolonged static content like news tickers or game HUDs
  • Peak brightness is lower than LG's higher-end OLED models, which may limit HDR impact in very bright rooms
  • At 65 inches, the TV is large and heavy, requiring a sturdy wall mount or stand and potentially a second person for setup
