LG UltraGear GX9— The Ultimate 45-Inch OLED Gaming Monitor for 2025

The LG UltraGear GX9 (45GX950A) is one of the most extreme gaming monitors released this year — a 45-inch OLED panel with a super-aggressive 800R curvature that wraps around your entire field of view. The standout feature is LG’s new Dual Mode system, letting you switch between ultra-high 5K2K resolution or an insanely fast 330Hz refresh rate. You can play cinematic story games in full clarity, then instantly jump into competitive mode with lightning-fast response.

In this test, we went beyond normal usage — not with one, but three GX9s side-by-side. Even a single unit is immersive. Three creates a cockpit-level gaming experience that feels close to VR without wearing a headset.

Unboxing and Setup Experience

Inside the box you get a heavy-duty adjustable stand, a huge power brick, HDMI 2.1 cable, USB-C cable, and DisplayPort 2.1 cable. The monitor itself is large even before assembly, but the 800R curvature becomes the highlight immediately. It bends aggressively to match your natural viewing angle and keep more of the image within your peripheral vision.

The back includes configurable RGB lighting and a full set of ports: HDMI, DisplayPort 2.1, USB-C, and USB upstream for connecting accessories. The stand supports height, tilt, and angle adjustments, making it suitable for gaming, productivity, and content creation.

Dual Mode: Switch Between Max Resolution and Max Refresh

The GX9’s Dual Mode is easily the most powerful feature. A single button lets you swap between:

• Full 5K2K resolution at 165Hz for cinematic visuals
• Lower resolution 330Hz mode for competitive gaming

You can even shrink the active screen area into 37-inch, 27-inch, or even 24-inch 16:9 layouts. This is perfect if you’re used to smaller esports monitors and don’t want to scan your eyes too wide.

It’s essentially multiple monitor sizes inside one display — no extra hardware required.

Triple-Monitor Immersion Test

Running three GX9 monitors together creates a 7680×1080 panoramic wall of OLED panels. Motion feels incredibly real, especially in racing games and flight simulators. Your peripheral vision absorbs movement on the left and right screens, making your brain believe you are actually inside a cockpit.

Sound reflections between the curved displays add another layer of immersion. For open-world adventures, simulators, and cinematic games, the setup feels shockingly close to VR — without the discomfort or motion sickness.

Even though this triple-monitor setup is extreme, it demonstrates how scalable and powerful the GX9 is. Most gamers will only use one unit, but the experience shows how far the panel can be pushed.

Gaming Performance and Display Controls

LG’s gaming dashboard is clean and easy to navigate. You can switch game modes, adjust VRR, toggle HDR, and activate presets for FPS, RTS, or custom profiles. The menu clearly displays your current refresh rate, color mode, and adaptive sync status.

In fast shooters like Call of Duty at triple-monitor width, you can maintain high refresh in the 300Hz range. For competitive players, shrinking the GX9 into a 24-inch 16:9 layout gives faster reaction time with less eye travel.

For immersive titles, switching back into the full 5K2K mode at 165Hz delivers rich colors, OLED deep blacks, and incredible clarity.

Productivity, Multitasking, and Media

The extra height of the 21:9 aspect ratio is one of LG’s key design decisions. It gives more space for timelines, browsers, and creative tools. Watching videos, editing content, and multitasking feel natural without the heavy letterboxing of ultra-wide 32:9 panels.

In productivity mode, the GX9 feels like two monitors blended into one smooth curved screen.

Who Is the GX9 For?

This is a premium display built for gamers who want everything:

• Competitive esports speed
• Cinematic ultrawide immersion
• OLED contrast and clarity
• Productivity-friendly workspace
• Flexible screen size and refresh rate

It’s expensive, but it eliminates the usual trade-offs. LG built a panel that can handle every scenario — gaming, work, entertainment, and simulation — without forcing you to compromise.

Final Thoughts

The LG UltraGear GX9 is one of the most versatile gaming monitors ever released. The dual-mode system gives you full control over your gaming style, while the massive curved OLED panel creates a deeply immersive environment. Whether you use it as a single display or build a full simulator setup, the GX9 stands out as a top-tier monitor built for the future of gaming.
