Product Overview
The Samsung Odyssey Neo G9 LS57CG950NWXXL is an ultra-wide gaming monitor designed for users who want a large, immersive display for gaming, entertainment and productivity. Its 57-inch-class screen uses a 32:9 aspect ratio and Dual UHD resolution of 7680 × 2160, providing a broad workspace for supported games and applications.
The 1000R curvature brings the screen around the viewer's field of vision, while the VA panel, Quantum Dot Color and Quantum Mini LED backlighting combine to deliver rich colours and controlled contrast. A 240Hz refresh rate and 1ms GTG response time add high-speed performance for compatible gaming systems.
Immersive Dual UHD Display
The 57-inch-class display offers a 7680 × 2160 resolution and 32:9 aspect ratio. This expansive format gives users room to view multiple windows side by side and enjoy compatible games across a wide field of view.
The 1000R curved panel is designed to create a more enveloping viewing experience. With typical brightness of 420 cd/m², a static contrast ratio of 2500:1 and support for up to 1 billion colours, the monitor is equipped for detailed visuals across gaming and everyday content.
High-Speed Gaming Performance
The 240Hz refresh rate supports smooth on-screen motion, while the 1ms GTG response time is designed to reduce visible pixel transition blur under the specified operating conditions. AMD FreeSync Premium Pro helps coordinate the display refresh rate with compatible graphics hardware to reduce tearing and stuttering.
Gaming features include Black Equalizer, Virtual AIM Point, Refresh Rate Optimizer and Super Arena Gaming UX. Auto Source Switch+ can detect a newly activated connected device and switch the input source automatically.
Quantum Matrix Technology and HDR
Quantum Matrix Technology uses Quantum Mini LED backlighting with 2,392 local dimming zones to control brightness across different areas of the screen. VESA DisplayHDR 1000 and HDR10+ Gaming support a wider range of brightness in compatible HDR content.
The monitor also features Quantum Dot Color and a typical DCI-P3 colour coverage of 95%. Factory tuning and a factory calibration report are listed by Samsung.
Connectivity and Multitasking
The Odyssey Neo G9 includes DisplayPort 2.1 and three HDMI 2.1 ports for connecting compatible gaming PCs, consoles and other video sources. A USB hub provides additional connectivity for compatible peripherals.
Picture-by-Picture lets you view content from two sources simultaneously, while Picture-in-Picture allows a secondary source to appear in a smaller area of the screen. The built-in KVM switch can help control multiple connected computers using a shared keyboard and mouse setup.
Compatibility note: To achieve the full Dual UHD resolution at 240Hz, Samsung specifies a graphics card and connection that support DisplayPort 2.1 with UHBR 13.5 or higher, or HDMI 2.1 with FRL 12Gbps. Actual performance depends on the connected hardware and its supported output modes.
Ergonomic Design and Comfort
The monitor features a height-adjustable stand with approximately 12cm of height adjustment, tilt and swivel support. A 100 × 100mm VESA mounting pattern also allows use with a compatible monitor arm or wall-mount solution.
Eye Saver Mode and Flicker Free are included for viewing comfort. CoreSync and Core Lighting+ add ambient lighting effects, while Adaptive Picture adjusts the picture according to the viewing conditions.
