Samsung's Odyssey G55C QHD Gaming Monitor provides 1.7x the pixel density of Full HD with incredibly detailed images, making gaming more lifelike than ever before. Featuring 165Hz refresh rate and 1ms response time (MPRT) for ultra-smooth action and frames with minimal blur. The 1000R display fills your peripheral vision and draws you into the game. AMD FreeSync™ keeps the monitor and the graphics card refresh rate in sync, and reduces image tearing for seamless, smooth scenes. Experience awe-inspiring graphics with HDR10, providing near limitless shades, for deep dark blacks and luminous whites. Eye Saver Mode minimizes blue light and reduces eye strain, enabling extended periods of game play. ¹"1ms" means one millisecond which is the range of avg. response time between 1.00ms to 1.99ms truncated to whole number. Based on MPRT measured under internal test conditions. Results may vary by content and monitor settings (requires ‘Extreme mode' setting). MPRT(Moving Picture Response Time) measures the time taken for a pixel to transition from one image frame to another (motion blur measurement).
