I think I understand what you mean. :) Before posting this I fired up my fiance's computer and put this image on his desktop and and on mine. I had thought our monitors were fairly similar, but there was actually a very big difference! On his monitor the image looked dark and the colours murky. I opened up the settings for both monitors and set his exactly the same as mine, but the image still looked very different. I had to end up tweaking his settings for a while to try and get it looking the same as mine, or as close as possible. So, I guess each monitor 'sees' things differently, and using the same settings doesn't always work. Those calibration tests really came in handy. :)
