Samsung 400EX(N) - Manual (Page 154)

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 verti-
cally 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 recom-
mended.
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.
