LG UltraGear 39GX950B OLED Monitor Review: Ultimate Gaming Experience















LG is stepping deeper into the premium gaming monitor space with the launch of the LG UltraGear 39GX950B OLED Monitor. First announced in December 2025, this high-end display is now getting closer to market availability, with confirmed sales in Japan and listings appearing in other regions.

This 39-inch ultrawide OLED monitor is designed for gamers and creators who want cutting-edge visuals, ultra-fast performance, and immersive viewing. With a 5K2K resolution, advanced OLED panel, and dual refresh rate modes, it positions itself as a flagship monitor in LG’s UltraGear lineup.

LG UltraGear 39GX950B OLED Monitor Features

Massive 39-inch OLED Display with 5K2K Resolution

The monitor features a large 39-inch OLED panel with a 5120 × 2160 resolution and a 21:9 aspect ratio. This ultrawide format provides significantly more horizontal screen space compared to standard 4K displays, making it ideal for both gaming and multitasking.

1500R Curved Screen for Better Immersion

With a 1500R curvature, the screen wraps around your field of view, enhancing immersion during gameplay and media consumption. It feels more natural to the eyes, especially on a display of this size.

Dual Mode Refresh Rate (165Hz / 330Hz)

One of the standout features is LG’s VESA-certified Dual Mode:

  • 165Hz at full 5K2K resolution
  • Up to 330Hz at 2560 × 1080 resolution

This flexibility allows users to switch between ultra-high resolution for visuals and ultra-high refresh rate for competitive gaming.

4th Gen Tandem OLED Technology

LG has equipped this monitor with its latest 4th Gen Tandem OLED panel, offering:

  • 335 nits typical brightness
  • Up to 1500 nits peak brightness (HDR)
  • VESA DisplayHDR True Black 500 certification

The result is deep blacks, excellent contrast, and vibrant colors that OLED panels are known for.

Exceptional Color Accuracy and Depth

The display supports:

  • 99.5% DCI-P3 color gamut
  • 10-bit color depth (1.07 billion colors)
  • A massive 1,850,000:1 contrast ratio

This makes it suitable not only for gaming but also for high-end content creation and media work.

AI Upscaling with Onboard Processor

LG has included an onboard processor that performs AI upscaling. This means lower-resolution content from connected devices can be enhanced to near 5K2K quality without needing a powerful GPU.

Top-Tier Gaming Performance

For gamers, the monitor delivers:

  • 0.03ms (GtG) response time
  • NVIDIA G-SYNC compatibility
  • AMD FreeSync Premium Pro support

Additional gaming tools like Black Stabilizer, Dynamic Action Sync, FPS counter, and crosshair overlays further enhance the experience.

Advanced Connectivity Options

The monitor supports modern connectivity standards:

  • DisplayPort 2.1
  • HDMI 2.1
  • USB Type-C with 90W power delivery

This ensures compatibility with high-end PCs, consoles, and even laptops via a single cable.

AI Sound and Built-in Speakers

It features dual 7W speakers with AI Sound processing, capable of separating in-game audio elements and simulating a 7.1.2 surround experience. While not a replacement for a dedicated sound system, it’s a strong addition for built-in audio.

Eye Comfort and Ergonomic Design

The monitor includes UL-certified eye comfort features such as:

  • Reduced flicker
  • Low blue light technology
  • Anti-glare coating

Physically, it supports tilt, height, and swivel adjustments, along with a nearly borderless design and wall-mount compatibility.

LG UltraGear 39GX950B OLED Monitor Price

The LG UltraGear 39GX950B OLED Monitor is expected to be priced around $2,179 (based on China pricing of CNY 14,999). Availability will begin in Japan from April 9, while global availability is yet to be confirmed.

LG UltraGear 39GX950B OLED Monitor Review

The LG UltraGear 39GX950B OLED Monitor is clearly built for users who want the best of everything—size, performance, and visual quality. From the moment you use it, the OLED panel stands out with its deep blacks and incredible contrast, making both games and movies look stunning.

The 5K2K resolution combined with the 21:9 aspect ratio creates a truly immersive experience. Whether you're gaming or working, the extra screen space feels incredibly useful. Multitasking becomes smoother, and games feel more cinematic.

What makes this monitor particularly interesting is its Dual Mode refresh rate. Being able to switch between 165Hz at full resolution and 330Hz at a lower resolution gives it versatility that most monitors lack. It adapts well to both competitive gaming and high-quality visual experiences.

The AI upscaling feature adds another layer of convenience. It allows users to enjoy sharper visuals even without upgrading their hardware, which is a practical benefit for many users.

Gaming performance is top-tier. The near-instant response time, combined with G-SYNC and FreeSync support, ensures smooth and tear-free gameplay. Features like Black Stabilizer and Dynamic Action Sync give competitive players an edge.

The built-in speakers and AI Sound are surprisingly capable for a monitor, though serious gamers will still prefer external audio solutions. On the design front, the monitor feels premium, with ergonomic adjustments that make long sessions more comfortable.

However, all these features come at a cost. This is not a monitor for budget users, and its premium pricing places it firmly in the high-end segment.
