Just received a 2007WFP yesterday. There is no banding issue what so ever in any of the three settings!! I ran it though several gradient tests and am happy to say that there is no banding issue in any of the different settings!!!!
I have revision A02 and there is quite a bit of banding and dancing of colors in multimedia mode as well as gaming mode. Are you using DVI? I don't believe Dell has fixed the other two modes.
The banding issues are a side effect of the processing done by the LCD controller (Faroudja chip).It's not a "bug" of the chip, it's "aside effect" of the algorithm used for improving the colors, so it can not be fixed in the chip , without eliminating the feature itself)
Faroudja chip does a number of improvements, of the image ( scaling, color compensation), but has a side effect the color banding. By the way the chip is used in a number of TV's and is considered one of the best in it's class. Same company makes one of the best upscaler chips used in upconverting DVD players.
The processing of the chip is disabled in Desktop mode but will stay on in the other 2 modes. Is your choice to chose which mode you need and if you want the chip processing to be on or off ( depending of the mode). If you use the monitor in it's native resolution, connected to a PC most likely you will want to use the Desktop mode ( with rev A02). If you use the monitor, for example connected directly to another video source (or for PIP) you may decide that the image is improved by using the Faroudja chip processing so use one of the other two modes.
"Fixing" the banding in all modes means disabling Faroudja in all 3 in other words completely eliminating the "modes" section which does not make sense. In the current configuration you can still select whatever fits better your configuration. The mistake was that the original firmware did not include an option to disable the processing, for the cases when it is undesirable, which rev A02 does.
I got mine today. 2007FP LPL UXGA LM201U05 Rev A02 it still have the banding problem when using DVI connector (tested on the desktop mode). But this Rev A02 fixed the text fuzzy and the flickering issue. Too bad it had dead pixels so I need to return it and wait for another replacement. Sigh so much hassle!!!
I purchased the monitor only as brand new from DELL. It is connected via DVI cable to an ATI X300 PCI-e 256mb video card in a NON-DELL PC. I tested all settings again, and still there is no banding issue! Ran it through several gradient tests with no ill affects... Maybe I just got lucky or maybe it has something to do with the video card??
