So after the prints thread on here I finally bought a colorimeter and calibrated my monitor last night. Followed the software, put the puck on the screen, waited, done. But now everything looks yellow/warm and kind of dim compared to before. White web pages look like old paper. My photos look warmer than they did yesterday too.
Did I mess something up? I picked the default settings it suggested, I think 6500K and some brightness number. Should I redo it?
