Ultra-Fast 300Hz Refresh Rate & Genuine 1ms (GtG) Response Time

Maximum Frame Rates and Minimal Motion Blur for Absolute Esports Control

Experience next-level motion fluidity with a native 300Hz refresh rate that pushes five times as many visual frames per second as standard 60Hz displays. High-speed action, rapid character tracking, and quick camera flicks are displayed with surgical precision, eliminating input lag and allowing instant visual recognition of moving targets in competitive shooters like Valorant, CS2, Apex Legends, and Overwatch 2.

Working in harmony with the ultra-high refresh rate, the true 1ms (GtG) response time instantly transitions panel pixels between states. This virtually eliminates motion blur, smearing, and ghosting artifacts during fast-paced play, ensuring every crosshair placement remains sharp and clear.

Fast IPS Panel with 99% sRGB & HDR10 Dynamic Contrast

Vivid Esports Visuals, Wide Viewing Angles, and Accurate Color Performance

Engineered with modern Fast IPS panel technology, the 2026 Odyssey G4 combines lightning-fast pixel transitions with pristine color fidelity. Broad 178-degree horizontal and vertical viewing angles ensure consistent visual performance, preventing color distortion or contrast shifts regardless of your viewing position.

Covering 99% of the sRGB color space, game worlds and character skins appear vivid and lifelike. Supported by HDR10 dynamic contrast enhancement, dark shadows reveal hidden depth while highlights stay bright and defined, allowing you to easily spot enemies lurking in low-lit map zones.

NVIDIA G-Sync Compatible & AMD FreeSync Premium

Tear-Free, Stutter-Free Display Synchronization Across Heavy GPU Loads

Prevent screen tearing, stuttering, and image jitter from ruining critical game moments. The Odyssey G4 HG402 features native NVIDIA G-Sync Compatibility and AMD FreeSync Premium support, dynamically matching the monitor’s refresh rate with your graphics card frame output.

This active synchronization ensures smooth visual frame delivery during heavy GPU loads, sudden frame-rate drops, or intense multi-character combat scenes without introducing additional display input lag.

Ultrawide Game View & Advanced In-Game Enhancement Tools

Expanded Aspect Ratio Perspective and Auto Signal Detection

Gain additional situational awareness with Ultrawide Game View. By shifting the monitor aspect ratio from standard 16:9 to an ultra-wide 21:9 format, you unlock additional peripheral vision across sports simulations, racing games, and tactical map configurations.

Integrated tools like Black Equalizer let you brighten dark game areas without overexposing lighter zones, while Auto Source Switch+ automatically detects connected PCs or consoles as soon as they power on, eliminating manual OSD navigation.

Fully Ergonomic Stand & Eye Comfort Certification

Tailored Physical Comfort with Advanced Flicker-Free Eye Care

Designed to support long competitive grinding sessions, the Odyssey G4 comes with a highly adjustable Ergonomic Stand. Easily customize height up to 120mm, tilt (-3° to +22°), swivel (-15° to +15°), or pivot 90 degrees into vertical orientation for specialized setups and streamer secondary displays.
