If you were using an oldish crt I would suggest that is "blooming" - 
lots of white in the picture increase electron beam current which 
enlarges the picture somewhat. Black backgrounds are in reverse. But 
you are seeing this on lcds as well, so it looks like an "optical 
illusion", like the old favourite of which line is longer:

Dunno what one can do about that it, it comes down to how the brain 
decodes the signals on the optic nerve...

Me too, and to me they all look more or less the same :-) In my case, I 
have 7 years worth of fixing the things and critically examining the 
display quality when calibrating and adjusting them. I've developed an 
automatic gain control in my head that compensates for differences :-)
