2007FPW Really Fixed?

I know most are tired about this whole banding issue, but I've looked through many threads and I haven't found the answer I'm looking for. Is banding on the 2007FPW revision A02 really fixed? People have said that they are, but looking at mine, I still see banding. If I make a black-white gradient (horizontal, vertical, diagonal, radial) in Photoshop, there is apparent banding, although it is a lot less than the other modes.

Is the banding just inherent in a program like Photoshop? Keep in mind the "dither" option is unchecked. In the gradlin.exe program there is still a tiny bit of thin vertical bands. Can people with either the A01 or A02 comfirm that theirs is band-free in photoshop?

Oh yeah, could you tell me if yours was made in China or Mexico? Mine is made in China (don't know if that even makes a difference).

    Grayscale does band the worst on the 2007WFP. You're description of tiny thin bands seem consistent with a fixed monitor though. Banding should be barely noticeble in the other colors.
     
    I wrote a mini-review on what banding looked on my A02 but I don't know where it is anymore.

    Unless you get a more expensive monitor your probably going to notice some banding. Although there really should be no banding in any monitors if they are really made well, I think it's a common issue with LCDs. I have the 2007WFP A02 and I see a very slight banding in some test modes, but other than that I notice nothing.

    I have an "audited" A02 made in Mexico.

    There is severe banding.

    Watch the trailer for Miami Vice, and when they flash those red and blue lights on a black background, you can then see.

    Movie trailers are typically very poor tests for banding

    Really? Why is that? I was watching the HD version, too.

    Well, it's not really a standardised source and video compression can affect the result. Try one of these test programs:
     
    gradlin-v0.2-fs.exe  - RGB gradient test screens
    Checkemon  - Test screens for solid color, gradients & more.
    Monitor Test  (Patel) - Test screens for gradients, solid colors, geometry & more.

    GBCUE is out to lunch and replying to every thread. He is showing a screen cap (not camera picture) which is a good thing I guess because otherwise it might not be obvious that this is CLEARLY a source problem, not a monitor problem. He will get a replacement and it will do the same thing.

    It wouldn't make a difference if I took a camera picture or not. It's still capturing the same thing.

    Do you have a single clue how computers work? When you do a print screen or use some other screen capture program, you capture the source of the image. The monitor has nothing to do with it.

    You could disconnect the monitor put it in a box and ship it to dell. Do printscreen and you will get the same result.

    You have proved beyond a shadow of a doubt that you have source problem, since you are showing us the source image. That source shows the problem. So of course the monitor shows the problem. It is faithfully rendering your bad source material.

    Think man. If your monitor has a burnt pixel, do you think it will show up burnt when you do a screen capture.

    If you don't understand how computers work, ask, don't assume and post in twenty messages something that proves you don't know what you are talking about.

    This is also the reason people suggest using some standard test like gradlin or its output if you don't want to get the program:

    Unless you know the source is good you can't test anything. That source compressed video you are using has banding in it, so it is completely invalid as a test.

    I've recently come upon this issue as I'm searching for a good flatpanel to take to college and carry up to the 4th floor of my dorm, vs. my bulky, heavy 19" M993 which I've been doing that for previously. The 2007(W)FP seemed like a good choice aside from the banding issue. I've read the entire 93-page thread, and I've searched the forum a bit, so I understand that the color banding issue is largely fixe;, but is it fixed in all modes? The sticky post by Chris seems to suggest that it's only been fixed for Desktop mode:

    "This eliminates the banding issue when using the Desktop mode only (not in Multimedia Mode or Gaming Mode) using 1680 x 1050 at 60 Hz for the 2007FP/WFP and 1920 x 1200 at 60 Hz for the 2407." (http://forums.us.dell.com/supportforums/board/message?board.id=dim_monitor&message.id=60479)

    Also, has anyone found out or figured out what "Adaptive Color and Contrast" or "Active Color Management" actually are, and if disabling these have resulted in degraded performance in other areas?

    Thanks!
