Picture is fuzzy | • Adjust the contrast and brightness (page 6). |
| |
| • 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 |
| |
| (page 9). |
| |
| • If CANCEL MOIRE is ON, the picture may become fuzzy. Decrease the moire |
| |
| cancellation effect or set CANCEL MOIRE to OFF (page 10). |

Picture bounces or has wavy | • Isolate and eliminate any potential sources of electric or magnetic fields. Common |
| |
oscillations | causes for this symptom are electric fans, fluorescent lighting, or laser printers. |
| |
| • If you have another monitor close to this monitor, increase the distance between them | EN | |
| to reduce the interference. |
| |
| • Try plugging the monitor into a different AC outlet, preferably on a different circuit. |
| |
| • Try the monitor on a different computer in a different room. |

Picture is flickering | • Set the refresh rate on the computer to obtain the best possible picture by referring to |
| |
| your computer’s manual. |

| |
ghosting | occurs. Excessive cable length or a weak connection can produce this symptom. |

|
Wavy or elliptical (moire) | • Set CANCEL MOIRE to ON and adjust the degree of moire cancellation until the |
| |
pattern is visible | moire is at a minimum (page 10). |
| |
| • 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. |
