Information Restrictions because of the application of the Image Retention Free algorithm. • The Pixel Gray Insertion algorithm has been applied. - Therefore, the luminance is reduced (25~30%) on the basis of the original luminance. In addition, the inserted gray pixels may appear distorted (mesh, jitter) when the screen is viewed by a user who is moving horizontally or vertically or is viewed from a short distance • When watching the screen moving horizontally or vertically: The mesh noise occurs and the luminance is reduced (25 ~ 30%) • When watching the screen from a short distance: The jitter noise causes one-pixel-size characters and lines to tremble. • Flickering that appears in a specific pattern Usage Guide • Usage Conditions: Using it for 12 hours and then turning it off for 2 hours is recommended.. • Factory Default: Image Retention Free function: OFF • To minimize the effects of the luminance reduction due to the function, using the function after setting the screen brightness to the highest level is recommended. E.g. MagicBright Mode: Entertain • A picture that is larger than a Four Pixel Line / Two Pixel Size character is recommended. - In a One Pixel Line / Character picture, the jitter noise or flickering may appear. 111
