    Hi all,

    I have a dell 20" widescreen attached to a mac mini. I noticed while rebooting today that the airport icon in the menu bar along with adium and quicksilver (all the icons that don't change or animate) were showing a slight trace of burn on the blue and gray background when rebooting. the menu icons like ram usage, cpu meter and net traffic (all the ones that change what they show) were not leaving a trace. this is evidence of burning no?

    its an lcd connected via dvi and should not be doing this. besides, even if lcd's could burn my display is set to go to sleep after 10 min.

    I don't understand.. why is this happening? is there anything I can do?

    If you wanna make sure, set it on a solid color fullscreen for a while and go out of the room and then come back and look....

    My guess is that there isn't really burn. There really shouldn't be burn... I would guess that it's much more likely that you're being tricked by the sensitization of your eyes, if you were watching it reboot.

    I tried screen testing apps that show solid colours and I could still see it on 2 colours (grey and white) but red and dark blue and black showed nothing.

    its called image persistence.

    this topic has come up before - do a forum search. in fact i think it came up a few days ago.

    apple has a support page for this. its not permanent - so don't worry.

    i'm too tired to find the link right now, but you should find it pretty easily.

    LCD's have a memory. They get "used" to displaying certain paterns and colors. Do remedy this, some how display an all white screen for as long as the stuck images were displayed on your screen. I use iPhoto slideshow and pause it on an all white image.

    I had a dell 2005fpw that had the same thing. I called dell and they replaced it. They then tried to deny that I sent the old one back, and kept calling me. I finally figured it out.

    The 23" ACD at my old job had burn-in or 'persistence' from iTunes being open all the time. As noted in previous replies, it is apparently an easy fix.

    wow! so many responses so fast! thanks for all the helps guys. I will do the all white screen with the screen tester I have. or will any colour that isn't black like the menu icons work?

    Sorry, not the best phrasing. I mean that after having dell call me like 50 times threatening to charge me for the lcd I sent them (and had proof of), I finally talked to someone who had the authority to make people stop calling.

    Geez I've never had this problem on my ViewSonic VX910 I hope that doesn't happen! I had a NEC MultiSync 15 with MS-DOS burned in very very strongly.

    LCD Test there are other lcd test programs for os x, Burn In was another, there are also QT movies that cycle through the colors, a single one at a time.
