27 inch OLED QHD 280Hz gaming monitor

This 27 inch LG UltraGear monitor uses a flat OLED panel with a 2560 x 1440 resolution and a 280Hz refresh rate. A 0.03ms response time and 1,500,000:1 contrast ratio deliver instant pixel transitions and deep blacks. The display covers 99.5% DCI-P3 and shows 1.07 billion colors for accurate color work.

Competitive gamers needing speed and HDR contrast

The 280Hz refresh rate and adaptive sync support suit fast-paced esports and AAA titles where motion clarity matters. Creative professionals gain from the wide gamut and VESA DisplayHDR True Black 500 certification. Users who require higher pixel density for text-heavy workflows or a curved screen should look elsewhere.

0.03ms response time with 280Hz refresh

The 0.03ms gray-to-gray response combined with a 280Hz panel determines whether motion stays sharp in the fastest scenes. If your GPU cannot sustain high frame rates at 1440p, the panel speed will not be fully utilized.
