The 39GX950B-B is a 39-inch 21:9 curved 5K2K resolution (5,120×2,160) ultrawide gaming monitor.
It features LG's 4th generation OLED panel, Tandem OLED.
By evolving the light-emitting layer from the previous three layers to a four-layer structure, it achieves both high brightness and improved color reproduction while reducing power consumption.
It covers 99.5% (standard value) of DCI-P3, the color gamut for digital cinema, enabling precise color reproduction.
Support for VESA Dual Mode
Supporting VESA Dual Mode, which allows for switching between resolution and refresh rate, the monitor can display at 5K2K (5,120×2,160) @ 165Hz or UWFHD (2,560×1,080) @ 330Hz.
The screen size can also be switched from 39 inches to 24.5 inches, and the aspect ratio can be toggled between 21:9 and 16:9.
It achieves a response speed of 0.03ms (GTG), making it possible to display clear images even in scenes with intense movement.
AI Functions to Support Gameplay
The monitor is equipped with three AI functions to improve video and audio performance for immersive gameplay, including:
- AI Upscaling: The built-in processor upscales low-resolution content to 5K2K resolution in real-time.
- AI Sound: Optimizes audio according to the content, making sound effects such as footsteps clearer.
- AI Scene Optimization: AI recognizes the displayed content and automatically adjusts major image settings to optimize the display.
Functions Supporting Comfortable Gameplay
The monitor supports AMD FreeSync Premium Pro Technology and NVIDIA G-SYNC Compatible, which suppress tearing and stuttering.
It has also obtained VESA AdaptiveSync Display certification, a standard for gaming displays that achieve high refresh rates and low latency.
Additionally, it features the Live Color Low Blue Light function, which reduces blue light without changing colors, providing eye-friendly support even during long hours of gameplay.
The price at the LG Official Online Shop is 296,780 yen.
During the pre-order period until June 3, 2026, it can be purchased for 229,800 yen, which is 23% OFF.
