Color is not uniform | • Degauss the monitor (page 15). |
|
|
| 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. |

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 |
|
|
| to reduce the interference. |
|
|
| • Try changing the direction of the monitor. For example, if it is facing South, turn it so |
|
|
| that it is facing East. |
|
|
| • Move the monitor away from power lines or place a magnetic shield around it. |
|
|
| • Try plugging the monitor into a different AC outlet, preferably on a different circuit. |
