Screen image is not centered | • Adjust the size or centering (pages 5 – 6). |
or sized properly | • Some video modes do not fill the screen to the edges. This problem tends to occur with |
| certain video boards. |

Edges of the image are | • Adjust the geometry (pages 6 – 7). |
curved |

White lines show red or blue • Adjust the convergence (pages 9 – 10). | |
shadows at edges |

Picture is fuzzy | • Adjust the contrast and brightness (page 4). |
| • Degauss the monitor (page 10). |
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 9 – 10).
• If the moire is cancelled, the picture may become fuzzy. Decrease the moire cancellation effect (pages 9 – 10).
Picture bounces or has wavy oscillations
•Isolate and eliminate any potential sources of electric or magnetic fields. Common 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 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. |

Picture appears to be | • Eliminate the use of video cable extensions and/or video switch boxes if this symptom |
ghosting | occurs. Excessive cable length or a weak connection can produce this symptom. |

Wavy or elliptical (moire) | • Cancel the moire (pages 9 – 10). |
pattern is visible | The moire may be modified depending on the connected computer. |
| • 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 14). This aperture grille |
(wires) are visible | allows more light to pass through to the screen giving the Trinitron CRT more color |
| and brightness. |
Hum is heard right after the • When the power is turned on, the
power is turned on | degauss cycle is activated, a hum may be heard. The same hum is heard when the |
| monitor is manually degaussed. This is not a malfunction. |
