Main Highlights

[Seamless Dual Mode Switching] The VESA-Certified dual-mode function provides gamers with two modes: UHD 4K@240Hz ultra-high resolution and FHD 1080P@480Hz ultra-high refresh rate. Gamers can switch between the two modes at the touch of a button according to different scenarios, allowing one monitor to meet the demands of both 3A blockbuster and FPS games.
[Vivid OLED Panel] This OLED monitor features an ultra-thin 5mm LG OLED panel that emits light independently for each pixel and can be turned completely off. Supporting HDR True Black 400, it achieves an ultra-high contrast ratio of up to 1,500,000:1, providing more vivid colours and true-to-life details. At the same time, it consumes significantly less energy than conventional LCD displays, as the black pixels do not emit any light at all when displaying black content.
[Extreme Gaming Engine] Ultra-high refresh rate of 4K@240Hz/1080P@480Hz and 0.03ms GTG response time provide a competitive edge for gaming, and dual-certified anti-tearing technology from Adaptive Sync delivers a silky smooth and shadow-free winning experience.
[Cinematic Colour Coverage] This 4K OLED monitor displays colours up to 10-bit (1.07 billion), achieving 137% sRGB/10% DCI-P3 gamut volume, and 100% sRGB/99% P3-DCI gamut coverage for true-to-life colour tension in games and movies. Two built-in 5W speakers for an immersive audition experience.
