This sounds like a camera profile issue or a default-settings-off issue.
What camera model?
What camera profile do you have set in Camera Calibration down at the bottom of the righthand panel in Develop?
What OS version?
How do you calibrate your monitor: Spyder, i1Display, ColorMunki, etc?
Can you show us what you mean with a screenshot attached to a forum message using the web interface to the forums?
