I also have the PRO-100 and use the Dell U2410, actually I use a dual U2410 setup at work and a single U2410 at home.
In both locations I have the set the brightness level differently. At work there is a ton of overhead fluorescent lighting, which I would love to turn off, so the monitors are a little brighter in this location.
At home the U2410 is set at it's lowest brightness setting to achieve proper calibration. The prints still come out a little darker when using the Pro9000 but I haven't noticed that issue with the PRO-100.
Currently I am battling a color cast while printing in Black and White with the PRO-100. It seems that I just cannot turn off the color. I have black and white images that seem to have a greenish tint to them when print on Pro Luster paper, with or without the “Black and White Print” button selected.
I tried a test image from Northlight Images on Galerie Smooth Pearl and got the greenish tint when selecting “black and white print”, but not when I do not select the option.
BTW, all prints where printed with LR4 managing color, with the correct profiles set for medium and printer. I may have to find someone with a spectrophotometer to check the prints so I can create my own printer profiles.
Don't want to hijack the thread but, Anyone know of a place that I can send printed samples to for the creation of custom profiles?
