This article covers LG 39インチ Ultragear OLED カーブ ゲーミングモニター.

Overview

The LG 39-inch UltraGear OLED curved gaming monitor combines an ultrawide WQHD resolution with a 240Hz refresh rate, positioning it as a strong contender for gamers who want both immersion and competitive responsiveness. The OLED panel delivers a 0.03ms response time, effectively eliminating motion blur in fast-paced scenes.
The aggressive 800R curvature wraps around the viewer's field of vision, making it particularly well-suited for racing games, flight simulators, and story-driven RPGs. With both NVIDIA G-Sync compatibility and AMD FreeSync Premium Pro support, the monitor works smoothly with either major GPU ecosystem.

Connectivity & Compatibility

Video inputs include HDMI 2.1, DisplayPort 1.4, and a USB Type-C port. The USB-C connection carries video signals, data, and power delivery simultaneously, so a single cable can connect a compatible laptop while charging it at the same time.
Since the monitor supports both G-Sync compatibility and FreeSync Premium Pro, variable refresh rate works whether you have an NVIDIA GeForce or AMD Radeon graphics card installed. Built-in speakers provide immediate audio output without requiring external speakers or a headset.

Product Info

This model belongs to LG's UltraGear gaming monitor lineup, featuring a 39-inch OLED panel with a 21:9 ultrawide aspect ratio at 3440×1440 resolution. The 240Hz refresh rate and 0.03ms response time are among the key selling points for competitive gamers.
The display carries VESA DisplayHDR True Black 400 certification, with a 1,500,000:1 contrast ratio that showcases OLED's signature deep blacks and vibrant colors. An anti-glare coating on the OLED panel reduces reflections, helping to minimize eye strain during extended gaming sessions.
In terms of market positioning, this sits in the mid-to-high tier of OLED gaming monitors. The 39-inch size is relatively compact for an ultrawide, striking a balance between desk footprint and immersive screen real estate.

Best Use Cases

Racing and flight simulation enthusiasts will appreciate the 800R curvature, which fills the peripheral vision and enhances cockpit-view immersion. The wrap-around effect makes it easier to judge distances and spot track edges during high-speed driving.
Competitive FPS and action game players benefit from the 240Hz refresh rate and 0.03ms response time, which improve target tracking and reduce visual lag. The dual VRR support means the monitor adapts to whatever GPU you currently own.
Story-driven RPG players who value visual fidelity will find the DisplayHDR True Black 400 OLED panel particularly appealing. Dark dungeons and nighttime environments render with excellent detail, making it easier to spot enemies or environmental cues in shadowy scenes.
However, budget-conscious buyers may find the OLED premium hard to justify if they already own a high-quality IPS monitor. Additionally, since OLED panels carry a burn-in risk, this display is less ideal for office work that involves displaying static content for long periods.
