LG 34GX90SA-W 34" Ultragear OLED Gaming Monitor — 240Hz, 1ms, G-SYNC, webOS

Immersive OLED gaming on a sweeping 34-inch curve

Step into the action with LG’s 34GX90SA-W Ultragear OLED, a 34-inch curved monitor that blends size, speed, and superb contrast. The WQHD resolution (3440 x 1440) pairs with an 800R curvature to envelop your visuals and pull you closer to the scene, making fast plays feel more immediate and cinematic. Whether you’re piloting a sprinting racer, lining up a clutch sniper shot, or exploring richly crafted worlds, the display aims to deliver crisp edges, vibrant color, and a sense of depth that elevates immersion without sacrificing clarity.

At the core are two standout performance specs: a blistering 240Hz refresh rate and a near-instant 0.03ms GtG response time. In practice, this means smooth panels during rapid sequences and reduced motion blur, helping you track targets and react with precision. The 34-inch canvas is complemented by a striking 800R curve that wraps your peripheral vision just enough to feel involved without overwhelming sightlines. These traits are designed to complement competitive play as well as cinematic exploits on a single monitor.

Color, brightness, and depth you can see

• OLED panels deliver deep blacks and bright highlights, with a 1,500,000:1 contrast ratio for richer shadows and vibrant colors.
• 98.5% of DCI-P3 color coverage ensures cinematic greens, blues, and reds look closer to real life on screen.
• 1300-nits peak brightness supports bright scenes while preserving detail in highlights and speculars.
• DisplayHDR True Black 400 enhances contrast in dark scenes for more nuanced detail.

Fluid gameplay with adaptive sync

• AMD FreeSync Premium and NVIDIA G-SYNC compatibility work together to minimize tearing and stutter across PC and consoles.
• Adaptive sync is paired with OLED clarity to keep motion smooth during fast-paced matches and sequences.

Smart, flexible, and ready for action

Comfort, protection, and design

The monitor features a virtually borderless look with adjustable height, tilt, and swivel for a personalized setup. An anti-glare surface minimizes reflections, helping you stay focused during long sessions. A subtle RGB backlight adds mood to your battlestation, while LG’s OLED Care tools and a 2-year OLED limited warranty provide ongoing peace of mind.
