More 2005FPW problems...

I got my 2005FPW in December, and like many others it had really bad backlight problems that I noticed immediately, but there were two other probles that I noticed near the eft edge of the screen over the new few days. First, there was a fading of the colors, and second, there was what appeared to be a long delay for images to disappear from the screen (I know it's not related, but it looks like the "burn in" that happens with old CRTs).

I emailed Dell support, and got what appeared to be a pretty standard reply and an offer for a replacement. I didn't ask for a replacement in my original email, because I mainly wanted to know if this stuff was normal, but when I was assured that I'd get a monitor without these problems, I said OK, and sent the shipping information that was asked for.

Anyway I got my second 2005FPW (a couple weeks ago, but I haven't been around much to be able to deal with it until now), and the backlight was much better. Not perfect, but I could probably live with it. Unfortunately, the other two problems are also visible on the new one. :(

So, I will ask once again, are these problems normal? What are the chances that I would get two monitors with the exact same problems if they aren't? The only reason I have any confidence left at all, is that only a few people said they saw the same things when I asked in another forum.

Is there a a flawless 2005FPW out there, or should I just assume these are to be expected and return it completely? Is that even a possibility? It's been more than 30 days since the first order, but I've had the second one for less than that.

Here are two of the photos I originally emailed to Dell support:





If anybody else wants an easy way to test for this ghosting, try this.

I'd really appreciate any input from someone at Dell who knows something about these monitors (that's why I came here as opposed to calling or emailing again, because I heard this is the right place for that).

Thanks for your help.

Martin



PS: BTW, now there is a third problem that is really starting to bug me. There is a strange pattern that I see whenever I move my eyes across the screen and try to focus on something near the left edge. It looks like a dithering pattern, but it pretty regular, and disappears as soon as I try to focus on it. Really disturbing. It's like that singing frog. Again, it's only on the left side of the screen, so it's not my eyes (and I'm not crazy).

    Oh, and this is a DVI connection, but I've also tried it over VGA to a different computer, and S-video to my DVD player in a different room.

    Yes, mine will exhibit faint after effects as well, but for all I know this could effect many of the LCDs out on the market since I've never done this test before on any other LCD. Also I would have never noticed this if I hadn't read your post here. It's not something I'd notice in daily use. There is a slight fading of colors near the left edge (and I mean so slight that you don't know if its there or if you're seeing things) this is also something that I would never notice unless I was looking for it with a calibration tool.
     
    The effect you describe as a dithering effect has to do with how LCDs refresh themselves (yes LCDs still have to refresh themselves though this is a very different process for an LCD). All LCDs will exhibit some of this but it tends to become more apparent on faster panels. I beleive it has to do with a property called inversion, on some LCDs it comes across as an interlacing effect. The 2005FPW is excellent at keeping this in check if you ask me. I've used a 16ms Sony panel where this effect was very visible and annoying on moving objects.
     
    Quite frankly if you want to be this picky with the stuff on your screen then LCD may not be the technology for you. Though I don't even know how you can be happy with CRTs either. If you want to that picky both of my old Sony trinitrons ehibited very slight color deviations across certain areas of the screen just due to magnitization (even after degausing) that were so subtle that anyone else looking at it would probably tell me I'm seeing things. No offense, but I think you're being way too picky about this sort of thing. I'm a pretty picky person myself but as I said earlier to me this is a non issue. It's like commenting about flicker on a CRT running at 120Hz.
     
    To answer your question, I think that these are just the properties of this panel, and that there is a good chance that if you looked at any other LCD based on the same panel (I.E. the 20" Apple Cinema Display) you'd see the same issues. I'm sure that you'd also find a multitude of other defects and annoyances with every other LCD you look at on the market. It isn't a perfect technology and every panel has to basically try to balance the good vs. the bad.

    ajabbari,

    I appreciate the response, but I'd like to mention that I used two different Apple 23' Cinema displays (the older models) at work for over a year, have a Thinkpad, and had a Powerbook before that. None of which had any of the problems I'm seeing here (or the backlight problem that the first one had).

    I asked about these issues because I thought it's a bit odd that if they were somehow to be expected, that they would show up on just the three or four inches near the left side of the screen. To me that doesn't seem so much like a problem with LCD technology in general, as it does with this monitor in particular (or, as you say, the panel used).

    So, I wanted to know if that's really the case, or if it's just mine. If it's normal for the Dell because it's so cheap, I'd be happy to spend a bit more and look somewhere else.


    As for being picky, you're right. I am. I certainly noticed that my Powerbook's screen had a bluish tint, the Cinema Displays were not very bright in daylight, the Thinkpad's a bit undersaturated, and all my CRTs were a bit blurry, but I never really had a problem with those things. It's just when a screen isn't even consistent with itself that I start to have a problem.

    I've seen that ghosting problem before on the Dell 2000FP monitors. I went through 3 of them before the ones I got did not exhibit that weird ghosting effect. It almost appeared to be burned in and was most noticeable when you moved windows around (such as IM windows, IE windows, etc).

    I just bought a Dell 2001FP - hopefully that one won't have the same type of problems.

    The 2005 monitors shipped in Nov. & Dec  that have a backlight problem are totally unacceptable by any standard.

    Dell has acknowledged this problem and has started to ship a rivised version in january

    after getting 3 bad monitors in a row I went with the samsung 193p, about as perfect as you can get

    Well, after your initial posting, and despite my response, I couldn't help but do a bit more testing. There is a slight inconsistency in saturation and tone that is more noticiable with pink and purple backgrounds as you go from one side of the display to the other. The ghosting issue only exhibited itself on the grey background in your test after about a minute of having it on the test pattern. It doesn't seem to be apparent on other colors I've never run into it with normal use. Both of these problems are well documented with Apple displays based on the same/similar panels as well (which shouldn't excuse them, but puts them into some perspective). Check out the following links...
     
     
    Hopefully you'll forgive the dismissive tone of my initial response it seems that there may be more to these problems than I initially thought. I'll stand by my statement that these issues probably shouldn't affect average users as they are very subtle. However, it could be a major issue for graphic artists who require high levels of color precision and consistency in their displays.
     
    From the articles above it sounds like a lot of 20"+ TFTs tend to exhibit this behavior, so maybe you got lucky with those 23" cinema displays.

    ajabbari,

    Thank you for the xlr8yourmac link. I should have known to check there or Macintouch after hearing that it was the same panel. I've been out of the Mac loop for a little while, but I do know that if there are any flaws in Apple/Mac-related products, they will show up there.

    It doesn't give me much hope though, especially since this is something that does NOT seem to be noticed by a lot of the 2005FPW users. Maybe if something is done for the Apple displays, it will also have a positive effect on these. But that still leaves me with a dilemma...

    Do I call Dell about another replacement or do I call and ask for my money back? I have no interest in wasting my time or theirs, and if I can't get a monitor that won't have these problems, I want out (again, I've had this replacement for less than 30 days, so I figure it's possible that may still be an option).

    Or...

    Do I keep this, and wait a bit for them to get these problems sorted out, and then send it in for warranty repairs?

    KO cape,

    What do you know about this "acknowledgement" and the revised version? Is there actually a rev A01 version? Does it address any specific problems aside from the backlight issue?

    My Dec A01 is not very good. Pretty bad backlight issues in the corners and several stuck pixels.

    Anyone know when the JAN revs. start shipping?
