LG 45GX950A-B 45-in Ultragear 5K2K OLED Curved Gaming Monitor

In this review of the LG 45GX950A-B, the bottom line is simple: this monitor is for gamers and creators who want an ultra-wide, high-resolution OLED that prioritizes picture quality and speed. The screen's world-first 5K2K WUHD resolution on a 45' curved OLED delivers striking detail and deep blacks, while Dual Mode switching between 165Hz and 330Hz gives flexibility for cinematic play or competitive FPS. Performance and color accuracy are the main reasons to consider this display, though its size and advanced connectivity make it most valuable to serious users.

Key Features

• 5K2K WUHD OLED: The 5120 x 2160 resolution on a 21:9 curved 45' panel produces exceptional clarity and immersion for games and wide-format content.
• Dual Mode refresh: Switch between 165Hz at full 5K2K for detailed visuals and 330Hz WFHD for ultra-responsive competitive play with a hotkey.
• High peak brightness and HDR: Up to 1300 nits peak brightness with DisplayHDR True Black 400 brings bright highlights and deep OLED blacks to cinematic scenes.
• Fast response and sync: A 0.03ms GtG response time plus AMD FreeSync Premium Pro and G-SYNC compatibility minimizes ghosting, tearing, and stutter.
• Advanced connectivity: DisplayPort 2.1, two HDMI 2.1 ports and USB Type-C with 90W PD deliver high bandwidth and versatile connections for PCs and consoles.
• Comfort and eye care: The 800R curve and triple UL certifications for anti-glare, flicker-free, and low blue light reduce reflections and eye strain during long sessions.

Who It's For

This monitor suits competitive and immersive gamers who want both high resolution and fast refresh rates, plus content creators who need broad color coverage and deep contrast. The 21:9 aspect and 45' curved panel are ideal for simulation, racing, and cinematic single-player titles where field of view and visual fidelity matter.

It is less appropriate for users with very limited desk space or those who prefer a smaller, more budget-oriented display. Casual users who do not need ultra-wide resolution or professional color fidelity should consider simpler monitors with lower cost and smaller footprints.
