The LG UltraGear OLED 27GX790B is built for gamers who want every visual and competitive advantage. UltraGear's 27-inch 4th Generation OLED QHD resolution display delivers pinpoint clarity with UL Verified Perfect Black and Perfect Color¹, exposing incredible detail and nuanced highlights. VESA DisplayHDR True Black 500 adds deeper contrast and controlled brightness, giving gamers a sharper read on enemies, environments, and effects in every gaming scenario.
Speed is where this UltraGear OLED separates itself from others. Dual Mode² gives gamers two elite paths to victory: a 540Hz refresh rate at QHD resolution for high-resolution precision or 720Hz at HD for pure, unleashed speed. Paired with a near-instantaneous 0.02ms response time, motion stays clean and fast—ideal for tracking targets, reacting faster, and winning close engagements.
Your frames stay stable under pressure with NVIDIA G-SYNC compatibility and AMD FreeSync Premium Pro³, delivering tear-free, low-latency performance. VESA Certified ClearMR backs it up with verified motion-blur clarity, keeping visual noise out of the fight.
For next-gen setups, DisplayPort 2.1 ensures maximum bandwidth for high refresh rates and smooth data flow. A 4-pole headphone jack supports game audio and comms through one connection. And with full ergonomic control—height, tilt, swivel, and pivot—you can dial in your perfect competitive setup.
The 27GX790B delivers elite OLED performance, breakthrough speed, and incredible performance built for players who refuse to settle.
