Anyone considering the dell 2007 monitors ought to investigate the folowing performance issue:
Do a google search for dell 2007WFP banding and you will find that this product is a debacle due to very significant poor color performance for many, many users.
Start with the Dell Community Forums > Electronics > Monitors discussions and the similar discussions at sites such as AnandTech.
Dell is acknowledging the complaints and providing new units with upgraded firmware to address the problem, but it's not yet clear whether this fix works for users. The fix involves obtaining a replacement. You cannot update the firmware yourself. It seems that various restrictions on returns, such as the 21-day limit may be waived on this product. The situation is developing at this time with the fix announced on the forums this last week.
Also, users should be aware that the 2007FP and 2007WFP are separate models that currently use different panels: PVA for the 2007FP and S-IPS for the 2007WFP. Some users reported that both were S-IPS for a while after introduction and that Dell quietly switched the FP model to PVA, but it's unclear to me what the truth is. Note that S-IPS panels have much wider viewing angels than the PVA. The current Apple displays are S-IPS. I personally much prefer the appearance of S-IPS for color work because the off-axis performance is more consistent. PVA panels, such as the 1905FP and 2005FP can look amazing dead on, but color shifts dramatically off center.
Also note that Dell monitor color performance in general doesn't necessisarily improve with subsequent models. The 1907FP is considered to be a step backward from the 1905FP due to the use of a 6-bit chip in place of what was a 8-bit chip in the display electronics, leading to weaker color rendering (e.g., banding/contours).
Take what I'm saying with a grain of salt as I'm not a monitor expert. Users will be wise to do their own research.
