Overview

A 27-inch OLED gaming monitor built for competitive play with a 480Hz refresh rate and near-instant response. Suited for esports players and enthusiasts who want deep contrast and fluid motion.

OLED Visual Performance

The OLED panel delivers a 1,500,000:1 static contrast ratio and 98.5% DCI-P3 coverage for vivid, accurate colors. Peak HDR brightness reaches 1300 cd/m² while SDR brightness sits at 275 cd/m². The anti-glare surface reduces reflections in bright rooms.

Competitive Gaming Speed

A native 480Hz refresh rate paired with a 0.03ms gray-to-gray response time minimizes motion blur and ghosting. Adaptive Sync support includes NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro for tear-free variable refresh rates.

Connectivity and Ergonomics

Video inputs consist of one DisplayPort 2.1 and two HDMI 2.1 ports, plus a USB 3.0 hub with two Type-A and one Type-B connector. The stand adjusts 110mm in height, tilts -10 to 15 degrees, swivels ±30 degrees, and pivots. VESA 100x100 mounting is supported.
