Key features explained
- World’s First 5K2K OLED Gaming Monitor: This monitor offers an extraordinary 5120 x 2160 resolution on a 45” curved OLED panel. The ultra-wide aspect ratio and high pixel density immerse you in your games, making visuals exceptionally sharp and detailed. This is especially valuable for both expansive open-world games and multitasking productivity.
- 125 PPI: Sharp Text Clarity with Reduced Color Fringe: With 125 pixels per inch and an updated subpixel layout, the screen promises crisp, clear text and reduced color fringing. This means documents, browser tabs, and UI elements look sharp—an important benefit for users who split screen space between gaming and work.
- Bright 45″ OLED Picture: Up to 1300 nits with Deep Blacks and Brilliant Color: The OLED panel can reach up to 1300 nits peak brightness and covers up to 98.5% of the DCI-P3 color gamut, with a 1.5M:1 contrast ratio and DisplayHDR True Black 400 support. Expect vibrant colors, deep blacks, and high dynamic range for visually stunning scenes, whether you’re gaming or watching movies.
- Dual Mode: 5K2K 165Hz or WFHD at 330Hz: With Dual Mode, you can switch between ultra-high-resolution gaming at up to 165Hz, or drop to Wide Full HD for an ultra-fast 330Hz refresh rate. This lets you prioritize detail and immersion for story-driven games, or maximize speed and responsiveness for competitive titles like FPS, MOBA, or racing games.
- 0.03ms (GtG): Astounding OLED Speed: The near-instantaneous 0.03ms response time keeps fast-moving visuals clear and minimizes ghosting. This is a major advantage for competitive gamers who need every frame to be sharp and smooth.
- DisplayPort 2.1: Serious Connectivity for Serious Gamers: DisplayPort 2.1 provides high data speeds for high refresh rates and resolutions. The monitor also includes two HDMI 2.1 ports and a USB Type-C port with 90W power delivery, supporting a wide range of devices and fast laptop charging.
- Ultimate Frame Sync: FreeSync Premium Pro & G-SYNC Compatible: With support for both AMD FreeSync Premium Pro and NVIDIA G-SYNC, the monitor delivers smooth, tear-free visuals. This compatibility ensures a seamless experience across both PC and console gaming platforms that support variable refresh rate technology.
- Size Matters in OLED Gaming: Go wide. Not short.: The 21:9, 45” screen provides more vertical space than a 49” 32:9 display, offering a larger, more immersive view. This could be particularly appealing for gamers who want an ultra-wide experience with added height, or for professionals who benefit from extra vertical workspace.
- The 800R Curve: Surround Yourself in the Action: The dramatic 800R curvature enhances immersion by wrapping the display around your field of view. This design can make gaming and media consumption more engaging, especially in dark room setups.
- Certified Glare-Free & Low Blue Light: The monitor is triple UL-certified for anti-glare, flicker-free, and low blue light performance. This means reduced reflections, less eye strain, and improved comfort during long sessions—important for both play and productivity.
What to look for in this kind of product
- Display Quality (Resolution, Color, Contrast): For a premium gaming monitor, high resolution and color accuracy are key. The LG 45GX950A-B delivers a 5K2K (5120 x 2160) OLED panel with 98.5% DCI-P3 color coverage and a 1.5M:1 contrast ratio, making it stand out for both sharpness and vibrant color.
- Refresh Rate and Response Time: Competitive gamers seek high refresh rates and fast response times to minimize motion blur and input lag. This monitor offers up to 165Hz at 5K2K and up to 330Hz at WFHD, with a 0.03ms response time—among the fastest available.
- Adaptive Sync Support: Screen tearing and stutter can ruin fast-paced gaming. With both NVIDIA G-SYNC and AMD FreeSync Premium Pro support, the LG covers both major adaptive sync technologies.
- Connectivity: Versatile connectivity is important for attaching PCs, consoles, and other devices. The 45GX950A-B provides DisplayPort 2.1, two HDMI 2.1 ports, and USB Type-C with 90W power delivery, offering flexibility for multi-device setups.
- Ergonomics and Build: Comfort and adjustability matter for long sessions. The listing notes adjustable height, tilt, and swivel controls, as well as RGB backlighting for ambiance. Details on build materials are not listed.
