This article covers LG 有機EL ゲーミング モニター 32GX850A-B 31.5インチ.

Overview

The LG 32GX850A-B is a 31.5-inch 4K OLED gaming monitor that pushes the boundaries of what a desktop display can deliver. With a native 165Hz refresh rate and an astonishing 0.03ms gray-to-gray response time, it eliminates motion blur and ghosting even in the fastest-paced shooters and racing sims. What sets this monitor apart is its VESA Dual Mode support. You can switch between 4K at 165Hz for immersive RPGs and Full HD at up to 330Hz for competitive gaming. In Full HD mode, the screen size can also be adjusted to 24 or 27 inches, giving esports players a familiar field of view without sacrificing speed.

Connectivity & Compatibility

The monitor offers two HDMI 2.1 ports and one DisplayPort 1.4 input. HDMI 2.1 handles 4K/165Hz without compression, making it ideal for both PC and next-gen consoles. A built-in USB 3.0 hub with two downstream ports lets you connect peripherals directly to the monitor, reducing cable clutter on your desk. Variable refresh rate (VRR) is fully supported, with both NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro certifications. This ensures tear-free, stutter-free gameplay across a wide range of GPUs.

Product Info

Released in mid-2025, the 32GX850A-B sits at the top of LG's UltraGear OLED lineup. It's a premium-tier product that combines the deep blacks and vibrant colors of OLED with the high refresh rates demanded by competitive gamers. The standard warranty is one year, extendable to four years with product registration on LG's website. In the box you'll find the monitor, power cable, DisplayPort cable, USB upstream cable, and a quick-start guide. No speakers are included, so plan for external audio.

Best Use Cases

Competitive FPS players: The Full HD/330Hz mode with 24-inch screen scaling gives you the edge in fast-twitch scenarios. Just be aware of OLED burn-in risks if you leave static HUD elements on screen for hours. RPG and open-world enthusiasts: 4K/165Hz on a 31.5-inch OLED panel with DCI-P3 98.5% color gamut and Delta E < 2 accuracy makes every landscape and character model look stunning. HDR content truly shines here. * Multi-device users: With two HDMI 2.1 inputs and a USB hub, you can switch between a gaming PC, a console, and a work laptop without swapping cables. However, the lack of built-in speakers means you'll need separate audio gear.

Things to Consider

OLED burn-in is a real concern if you plan to use this monitor for static desktop work or productivity tasks. It's best suited for gaming and media consumption where the content changes frequently. The DisplayPort 1.4 port may require DSC (Display Stream Compression) to achieve 4K/165Hz, so HDMI 2.1 is the preferred connection for full bandwidth. Also, the standard brightness of 275 cd/m² is modest, though peak brightness reaches 1300 cd/m² in small highlights for HDR. ## FAQ
Q: Can I use this monitor with a PS5 or Xbox Series X? A: Yes, both HDMI 2.1 ports support 4K/120Hz from consoles. For PS5, 4K/120Hz is the recommended mode since 1440p/120Hz output isn't supported. Q: Does it have built-in speakers? A: No, there are no internal speakers. You'll need to connect external speakers, headphones, or a gaming headset. Q: What burn-in prevention features are included? A: LG includes pixel refresh, screen saver, and auto-dimming features that activate after periods of inactivity to reduce the risk of permanent image retention.
