Wavy or elliptical (moire) pattern is visible -, Due to the relationship between resolution, monitor Aperture Grille pitch and the pitch of some image patterns, certain screen backgrounds, especially gray, sometimes show moire which looks like wavy lines. This can only be eliminated by changing your desktop pattern. Hum is heard right after the power is turned on -> When the power is turn on, the Auto-degauss cycle* is activated. While the Auto-degauss cycle is activated, a hum may be heard.
