Screen condition: (Used) very clean usage. OLED screens designed for gaming (like the LG UltraGear or LG C-Series) offer visual experience and response speed that competitors cannot match. Here is a precise description of what the "Game Mode" offers on these screens: 1. Instant Response Thanks to OLED technology, pixel response time is 0.03ms (GtG). When Game Mode is activated, unnecessary image processing operations are turned off to minimize "Input Lag" to its lowest levels, making you feel that your movement on the controller appears instantly on the screen. 2. Absolute Black and Infinite Contrast In horror games or games with dark atmospheres (like Elden Ring or Resident Evil), the OLED screen completely turns off pixels to display true black. This highlights the finest details in dark areas without "Blooming" around bright objects. 3. Smooth Motion (Refresh Rate) These screens support high refresh rates up to 144Hz, 240Hz, or even 480Hz on newer models, completely eliminating "Motion Blur" in fast-paced FPS games. 4. Synchronization Technologies (VRR) Game Mode supports global synchronization technologies: NVIDIA G-Sync and AMD FreeSync Premium: to prevent "Screen Tearing". HDMI 2.1: to support 4K gaming at 120fps on PS5 and Xbox Series X. 5. Game Optimizer Interface LG screens provide a special interface that appears over the game, allowing you to: Black Stabilizer: Increase brightness only in dark areas to see hidden enemies without affecting overall image quality. Crosshair: Display a fixed aiming point in the center of the screen. Presets: Switch modes according to game type (RPG, FPS, RTS). 6. Eye Protection OLED screens are comfortable for the eyes during long gaming sessions because they emit very low levels of blue light compared to traditional LCD screens. Price is negotiable
