LG - UltraGear 45" WQHD OLED 240Hz 0.03ms G-SYNC FreeSync Premium Pro Gaming Monitor with DisplayHDR400 TRUE - Black

Black

The UltraGear 45” OLED Smart gaming monitor delivers the speed, scale, and smart performance serious players demand. The ultra-wide 21:9 display provides more usable screen space than a 49” 32:9 setup, giving you a broader view for deeper, more controlled gameplay. OLED technology powers vivid color, deep blacks, and a 1.5M:1 contrast ratio, enhanced by DisplayHDR True Black 400 and up to 98.5% DCI-P3 coverage. Stay competitive with a 240Hz refresh rate¹ and ultra-fast 0.03ms (GtG) response time for sharp, fluid motion with reduced blur. NVIDIA G-SYNC Compatible² and AMD FreeSync Premium Pro help keep gameplay smooth and tear-free. MLA+ technology boosts brightness up to 1300 nits peak for stronger highlights and better visibility. The 800R curve pulls you deeper into the action, while the virtually borderless design keeps your focus locked in. Built-in webOS lets you stream content or jump into cloud gaming—no PC or console required. USB-C with 65W power delivery simplifies your setup, while the adjustable stand keeps you comfortable through every session.
