| 194849 | 2003-11-26 06:52:00 | While using my computer today, the image being displayed by the monitor has gone fuzzy... As far as I know, this has only begun today, but I've now noticed it three times. It affects the entire monitor, which, for less than one second, displays everything in rough Z-like distortion lines. Kind of similar to what happens when your monitor doesn't like the set refresh rate, but it's not anything to do with that. I'm starting to worry that the monitor might be getting near the end of it's lifespan... it was previously used in an image editing environment, and was under heavy use (always on, etc). Earlier this year we had a transistor (or something) replaced, which, some of you might recall, had failed and caused the lack of green, thereby (a) making everything displayed horrible shades of magenta; and (b) causing the surrondings to look green after looking at the monitor for even slightly extended lengths of time. This was fixed, but I am getting worried about this. I suppose the best I can do is sit it out and see if it develops any further? |

| 194850 | 2003-11-26 09:59:00 | Does that look like a line displacement effect agent? Sounds like a momentary scan disturbance caused by either a glitched video signal from your computer, or an intermittent fault in the monitor. Are there any noises associated with it like buzzing etc? Cheers Billy 8-{) |

| 194851 | 2003-11-26 19:09:00 | try degausing you monitor. | ilikelinux (1418) | ||
| 194852 | 2003-11-26 19:18:00 | There weren't any sounds at all when the fuzziness occured. Neither do I know if degauss would do anything, but I'll have to see if it goes away if I do regular degausses. Note that I haven't noticed it again since yesterday, though it is early morning. |

| 194853 | 2003-11-26 20:10:00 | Degaussing is demagnetising and has absolutely nothing to do with visible effects on the screen, apart from the disturbance that occurs during the degaussing process, or the patchy discolouration that appears over time if the degaussing system ceases working. It has no effect on focus, image clarity or any other aspect of the display other than colour purity. In extremely rare circumstances (and dependent on the type of degauss current-control technology used) a degauss system can produce sporadic interference effects on screen but since the degauss coils surround the screen, the effects are similar to low level degaussing and involve concurrent image movement and colour effects. This problem is quite different and could be a dry or deteriorated solder joint on the scan transformer, a loose plug on the scan coils, a disturbance in the scan drive itself or one of many other causes. Best thing to do is note the conditions under which it appears, see if it is vibration sensitive when it does by aplication of controlled velocity impact testing (thump the monitor on the top or the sides and see if that has any effect). Keep an eye on the problem and report developments. Cheers Billy 8-{) |

| 194854 | 2003-11-26 21:24:00 | A cellphone in proximity to the monitor can cause similar effects, as it periodically (and briefly) communicates will the Cell to confirm its still alive. | godfather (25) | ||
| 194855 | 2003-11-26 21:33:00 | "Keep an eye on the problem and report developments" Having said that, it isn't a transitory effect that could be checked by an optometrist???:D :D |

| 194856 | 2003-11-26 22:54:00 | Good thought Chris, they could be night-time Zs from inside agent's eyelids that have crossed the temporal divide and are appearing in daytime instead. Does your head droop just before the Zs appear agent? Cheers Billy 8-{) :p [pre][b]If you heve a cellphone nearby agent, to test GF's theory just turn it off and on again. It will send a burst of data as it goes off, and another as it reconnects to the nearest cellsite. It is usually only digital phones that interfere with monitors. |

| 194857 | 2003-11-26 23:17:00 | Yes, my cellphone was about 60cm from the monitor all yesterday... but turning it on and off within 10cm of the monitor didn't do anything. And no, I don't think I was drooping just before it happened... I honestly don't know if it's related, but the first time it happened was when I pressed Control-Backspace to delete a few words in a post yesterday. |
