I'm waiting for two of these (2007wfp) to arrive, after having sent back the one 2005fpw i had (starting to regret that - i wanted two of them, but dell didn't have any left ), and I have a number of questions for 2007wfp owners.
Firstly, I've created a test image in PNG and TIFF forms (to ensure that PNG and it's own colour profiles aren't the problem, make sure they both display the same). The URLs:

Secondly, could you please put your monitors into DESKTOP mode.
Thirdly, could you ensure that NO OTHER INPUTS are connected to your LCD at the time of testing.
(this is my attempt at a controlled experiment)
Could a few please post some photos of their 2007wfp's displaying this test image in the following configurations (all in desktop mode):
- VGA mode, Default colour settings, Default contrast/brightness
- VGA mode, Lowered colour settings (30, 30, 30), Default contrast/brightness
- VGA mode, Lowered colour settings, Lowered contrast/brightness (30, 30)
- VGA mode, Lowered colour settings, Lowered contrast/brightness (30, 30)
- DVI mode, Default colour settings, Default brightness
- DVI mode, Lowered colour settings (30, 30, 30), Default brightness
- DVI mode, Lowered colour settings (30, 30, 30), Lowered brightness (30)
- DVI mode, Default colour settings, Lowered brightness (30)
With the test images above, you should see smooth gradients with dither on both horizontal and vertical, followed by smooth gradients (which are mapped at one 1px line per colour, unlike some of the test gradients around). The lower saturation gradients should also be smooth with no banding.
The six diagonal gradient squares should be smooth, the top 3 use dithering, the bottom three use flat lines.
The RGB squares should also be smooth.
Hopefully the following tests above will provide some sort of insight into where the problem lies. I'm thinking the digital logic chips inside the monitor might be clipping certain signals because they are slightly too strong, or some other strange phenomenon.
Anyhow, photos of these test images in the 8 above modes would be appreciated, and hopefully should prove helpful.
