I did my calibration on Saturday as my Dell 2408 just arrived.

I used Eye One Display 2, set Luminance to 2.2 (LCD Recommendation) *I think so.. I can't rem.*

Set it to 5500K or 5000K.

After calibration, instead of usual yellowish I seen, it became greenish. I would like to ask if there's anything I did wrong? I did set the RGB to 0, set the brightness and contrast correctly.

Any expert to guide me along?
