1. Based on publicly available information as of May 19, 2026, among gaming monitors introduced by consumer brands.
2. This product supports a refresh rate of up to 1000Hz (1100Hz O/C); however, actual 1000Hz performance may be affected by various external factors, including PC specifications (CPU, GPU, memory), game-specific frame rate limitations, operating system version, and graphics driver version.
3. To use the 1000Hz feature, the latest version of Windows 11 is required. The latest graphics driver and a DisplayPort connection are recommended.
4. Based on LG Electronics' internal testing, 1000Hz refresh rate signal input and operation at FHD (1920 × 1080) resolution were verified using systems equipped with NVIDIA GeForce RTX 50 Series graphics cards and AMD Radeon RX 7900 Series, RX 9060 Series, and RX 9070 Series graphics cards. Actual refresh rate, frame rate (FPS), and gaming performance may vary depending on CPU, GPU, memory, game settings, network conditions, and other system configurations. Some games may impose their own refresh rate or frame rate (FPS) limitations. In such cases, the product's maximum 1000Hz performance may not be available. Internal test results were obtained under specific test conditions and do not guarantee identical results in all user environments.
5. Support for a 1000Hz refresh rate does not imply or guarantee the achievement of frame rates of 1000 FPS or higher in any particular game.
This image presents key features of an LG gaming monitor, including a 300Hz refresh rate for fluid motion, IPS display with HDR and sRGB 99% color for vivid visuals, smooth gameplay with NVIDIA G-SYNC and AMD FreeSync Premium support, 1ms(GtG) response time for fast-paced gaming, and a virtually borderless design for an immersive setup.

1000Hz refresh rate helps deliver ultimate smooth motion and more frequent frame updates for competitive FPS gameplay. Whether tracking fast-moving opponents, landing precise flick shots, switching targets, or making critical micro-adjustments, smoother motion helps players perform these actions faster and more precisely. With up to 1100Hz overclock support, players can push the refresh rate even further for faster gameplay.
*Images have been simulated to enhance feature understanding, and may differ from actual use experience.
Go beyond NATIVE 1000Hz with support for up to 1100Hz overclock (O/C). Experience even smoother motion, faster responsiveness, and sharper visual tracking designed to keep you ahead in every competitive esports moment.
*Overclocked 1100Hz operation may limit Adaptive-Sync functionality, as AMD FreeSync™ Premium is not supported and NVIDIA G-SYNC® compatibility is only certified at 1000Hz, where performance is guaranteed.
*1100Hz overclock is evaluated based on internal testing.
*Simulated comparison due to video frame rate limitation.

MBR (Motion Blur Reduction) Pro helps reduce motion blur by lowering display persistence time during fast-moving gameplay. By briefly controlling the backlight between frames, it helps reduce the continuous image hold effect. This allows fast-moving objects to appear clearer and sharper with less motion blur, improving target tracking, motion precision, and reaction speed during competitive esports play.

Minimize tears and lags with NVIDIA® G-SYNC® compatible and AMD FreeSync™ Premium technology. Experience significantly reduced screen tearing and stuttering for smooth visuals with minimized motion blur and ghosting.
Enhanced with ATW(Advanced True Wide) Polarizer technology, the IPS display helps reduce screen reflections while maintaining vivid color expression from wider viewing angles. The result is clearer and more consistent visuals with improved visibility for immersive gameplay.
VESA DisplayHDR™ 400 and sRGB 99% (Typ.) bring richer color and deeper visual detail to every scene. Enhanced contrast helps reveal details in both bright and dark areas, allowing players to spot important visual cues more easily during gameplay.
*Overclocked 1100Hz operation may limit VRR functionality, as AMD FreeSync™ Premium is not supported and NVIDIA G-SYNC® compatibility is only certified at 1000Hz, where performance is guaranteed.
*Images have been simulated to enhance feature understanding, and may differ from actual use experience.
Engineered for precision, the stand includes an adjustment scale that helps users accurately set and customize their viewing position. The clearly marked scale enables fine-tuned adjustments, making it easy to create a personalized monitor setup designed for comfort, focus, and gaming performance.
