In view of this, thefollowing settings are strongly recommended.Note that image burn-in will still occur, though somewhat later, even aftermaking these settings and that burn-in cannot be suppressed. The moni-tor should be used in [FULL] mode as much as possible.1. Perform gray level settings to narrow the differences in brightness be-tween display and non-display portions of the image.2. Weaken the image adjustment contrast and brightness. (See P.28)3. Perform the Long Life settings. (P.45)
