If you were using an oldish crt I would suggest that is "blooming" - |
| 11 |
lots of white in the picture increase electron beam current which |
| 12 |
enlarges the picture somewhat. Black backgrounds are in reverse. But |
| 13 |
you are seeing this on lcds as well, so it looks like an "optical |
| 14 |
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 |
| 43 |
have 7 years worth of fixing the things and critically examining the |
| 44 |
display quality when calibrating and adjusting them. I've developed an |
| 45 |
automatic gain control in my head that compensates for differences :-) |
