LG UltraGear 45” - OLED 165Hz Gaming Monitor - 45GX950A-B

The LG UltraGear 45-inch OLED gaming monitor is engineered to deliver an advanced ultra-wide gaming experience with a 5K2K (5120 x 2160) resolution and a cinematic 21:9 aspect ratio. A high pixel density of 125 PPI is provided for sharp text clarity and reduced color fringing, making it suitable for both immersive gameplay and productivity tasks. Deep blacks, vivid colors, and a 1.5M:1 contrast ratio are achieved through OLED technology, while peak brightness of up to 1300 nits enhances HDR content with exceptional detail and realism.
