Display colours

Hello all I was taking some screenshot with the PMDG 737NGX when I compared them to other user's on this forum when I notinced that my displays are a bit darker. For example, I thought my terrain display had the correct colours, but it turns out that the amber colour doesn't look that light and the red is too red. Is that normal or is my monitor having colour troubles? I just calibrated it with a Spyder 3. What colour temperatures are you all using and what brightness adjustment on the NGX knobs are you guys setting for the ND?Thanks!
