Image persistence
- Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.

| 0.5 sec. 2 times ↔1 sec. 1 time Memory check error | |||
| The monitor displays nothing. (The power lamp illuminates orange.) | The monitor displays nothing when the power saving function of your computer is active. Hit any key on the keyboard or move the mouse. Connect the signal cable correctly. Check that the computer isn't turned off. | - | |
| - | |||
| The monitor becomes dark, flickers, or displays nothing though it was displaying images properly. | Replace the LCD panel with new one. Contact your MIT-SUBISHI dealer. | - | |
| There are black spots (which don't illuminate) or bright spots (which stay illuminated) on the monitor. | They are not a failure, but due to the characteristics of the LCD panel. | - | |
| The monitor has uneven brightness. This symptom may occur depending on the displayed images. This is not a failure, but due to the characteristics of the LCD panel. | - | ||
| Faint vertical stripes appear on the monitor. This symptom may occur depending on the displayed images. This is not a failure, but due to the characteristics of the LCD panel. | - | ||
| Flickers and moire patterns appear when a fine pattern is displayed. | This symptom may occur when a fine pattern is displayed. This is not a failure, but due to the characteristics of the LCD panel. | - | |
| Lines aren't displayed in correct width. This symptom may occur when an image of other than 3840x2160 resolution is displayed. This is not a failure, but due to the characteristics of the LCD panel. | - | ||
| "Afterimage" appears on the non-display area. This symptom may occur when the entire monitor isn't filled with the display area and the same image is kept displayed for a long time. This is not a failure, but due to the characteristics of the LCD panel. | P.4, P.10 | ||
| The contrast varies depending on the viewing angle Depending on the viewing angle (angle at which you view the monitor), the contrast varies. This is not a failure, but due to the characteristics of the LCD panel. | - | ||
| The display quality varies. | Because the LCD panel uses a fluorescent light, its display quality varies with the lapse of the operating time. In addition, the display quality is affected by the ambient temperature. This is not a failure, but due to the characteristics of the LCD panel. | - | |
| A faint object persists on the screen even after switching the displayed image. | This symptom called "afterimage" may occur when the same still picture is kept displayed for a long time. The faint object fades away gradually by turning off the monitor or displaying a motion picture. Sometimes it cannot be eliminated but this is not a failure. | P.4, P.10 | |
| The monitor flickers (when connected via a distributor). | Connect the monitor and the computer directly each other, not via a distributor. | - | |
Others
| Symptom | Cause | Remedy | Reference page |
| The resolution and number of colors cannot be changed/they are fixed. | Signals aren't input/output correctly in rare cases. | Turn off the monitor and the computer and turn them back on. | - |
