		• Degauss the monitor (page 13).
		If you place equipment which generates a magnetic field, such as a loudspeaker, near
		the monitor, or you change the direction of the monitor, color may lose uniformity.
		The degauss function demagnetizes the metal frame of the CRT to obtain a neutral
		field for uniform color reproduction. If a second degauss cycle is needed, allow a
		minimum interval of 20 minutes for the best result.
		• If red or blue shadows appear along the edges of images, adjust the convergence
		(pages 12 – 13).
		• If the moire is cancelled, the picture may become fuzzy. Decrease the moire
		cancellation effect (pages 12 – 13).

	• Due to the relationship between resolution, monitor dot pitch and the pitch of some
	image patterns, certain screen backgrounds sometimes show moire. Change your
	desktop pattern.

Two fine horizontal lines	• These wires stabilize the vertically striped aperture grille (page 17). This aperture grille
(wires) are visible	allows more light to pass through to the screen giving the Trinitron CRT more color
	and brightness.
