Latitude D800 screen burn-in

Latitude D800 running WinXP sp1, 15.5 inch LCD with NVidia TI4200/64 MB RAM

(background: I am a techie, have been in the business for about 12 years, and currently own 14 computers on my home network - I am into grid computers).

I just bought a Latitude D800 as my new main workstation for software development.  I was SHOCKED this morning to see a screen burn-in problem on my new notebook.  For those of you that don't know what I mean, about 10 years ago computer screens had a problem where they would display a "ghost" of a screen image that had been displayed for a long time.  This was why screen savers were developed in the first place, namely to prevent screen burn-in.  BUT, that problem disappeared long ago as the phosphors improved on CRT monitors, and LCD monitors never had it - until now?  None of my other notebooks ever had a burn-in problem. 

I am looking at my screen and seeing the ghost images of some windows I had up showing clearly on the background of an empty desktop.  Screen burn-in problems are back?  If they are, then TELL us about it.  Warn us to use screen savers and blank the screen quickly, etc.  I bought this latitude as a desktop replacement, and use it as if it were a desktop - which means I don't blank the screen and I tend to leave it on 7 by 24.

If these screen qhosts don't fade very soon, I am going to have to return this thing.  I still can't believe we are back to that old problem - with LCD panels no less.  Unbelievable.

    HI,

    I had the same problem. I call DELL and they replace it next day. Hope you have a good luck.

    Same story here...

    Noticed the shadowing/burn in right out of the box. As I started using my apps I noticed continued burn in mainly at the top and bottom. It is very, very noticable if you set your desktop color to dark grey for example (no wallpaper). This is terrible. I spoke with a couple Dell tech support techs. One suggested setting an active/colorful screen saver to sort of re-charge the various areas effected. Kind of strange. It did not work. So, called again, they sent a replacement screen, self install. Took about 45 minutes (was being very careful, afraid I was going to break the plastic bezel) Several tiny screws later... new (well... REFURBISHED) screen that they sent was installed. Booted up, no problems, life is good. Now, Monday, three days later the same issue is appearing. Very frustrating. After a half a day configuring it, apps, servers, databases... it's my development environment, calling tech support and installing the replacement screen... I may have to return it.

    Hopefully this is not the case with everyone, though it seems there is a real problem! I have used laptops since my first AT&T Globalist in '95, from IBM to Sony... have never had a screen issue. I do, however, like the computers performance and features. It's just hard to get past this screen issue. Even more so for 3,000 dollars... I could have purchased any laptop on the market...

    One of our D800s also developed this problem - or we just noticed it!  Either way it's only a week old and it has ghost images of screens that are no longer open.  I thought that this problem did not exists on LCD displays.  I'll call Dell tomorrow about it.

    We bought several of them for faculty.  The first two out of the box had this problem.  I contacted Dell and they said the same thing about running a screensaver to exercise the pixels.  Doesn't really seem to help. 

    I am guessing the rest will have the same problem when we roll them out.

    Same burn-in problems here for my one-month-old D800: top and bottom window ghosts. The support desk suggested me by email to run my screensaver over night. Didn't work.

    However, I read at Apple's site that the Cinema Wide Screens have the same problem, and Apple suggests to put a completely white image on the screen for about two times the burn-in time.

    I am really surprised that my screen has messed up so quickly. And without and warning from Dell.

    I have only had the D800 for a few days and already it's burnt in.

    Here's a quick picture I took. The screen is a medium blue. The ghosted outlines at the bottom are of my double high task bar. They are not reflections. You can almost make out the outline of the start menu button on the left.



    Can we get a definitive answer from Dell on has this been fixed with new hardware? No reason to replace it yet if it hasn't been fixed.

    Thanks,
    Jeff

    Here are some shots of my laptop.  The ripples you see are actually ripples from my wallpaper.  It has a picture of water in it.

    I have tried the screensaver thing.  That did not seem to help.  I'll try the white screen when I get a chance. 

    Even if that did work, would that mean that every day I use it I have to burn a white screen for 2 days?

    Thanks for the screen shot. Awesome! Mine is far worse at the top. I use several applications all day long (and night). I can literally almost read the various tool bars for example.




    It doesn't look like a screen replacement works... as I stated in my previous thread. I have come to really like this laptop though, even at it's crazy high rez... I hope I can keep it.




    I will be calling Dell today/tonight... This is a real issue... same screen is on the Inspiron 8500 too... man...




    Actually... on another thread, maybe related to the 8500, some techie guy suggested the follow cause;




    "it sounds like the modulators that control the current flow which in turn control the properties of the crystals aren't working properly, leaving your LCD with a memory" - "it shouldn't be that way - sounds like the fab plant produced a bad sheet."




    I for one would propose they produced more than "a" bad sheet... if this is truly the issue... I have an email out to a PhD in electrical engineering and computer science.. hmmm




    I will post the results of my call to tech support... who seemingly claim to know nothing of this growing epidemic




    Dell moderator??? Any help???

    Just noticed the same problem on my D800. I think I might try running an all white screen for a few hours to see what that does.

    I tried the whitescreen overnight.  Didn't seem to help.
