I see it in kitacanon's image but not in the one by kjonnnn. How does that relate to calibration? Wrong brightness/contrast?
If your screen crushes blacks, you may have been painting with a really dark gray thinking it was black, since you couldn't tell the difference in tones.
I had a background on my old crt monitor a couple years back, and looked pretty fine... until I calibrated the screen and it looked like crap, with posterization everywhere. If you're going to be doing photomanips, make sure you have everything color correct.
