this is true.Last time I worried about it (close to 20 years ago) it was a special monitor for graphic designers.
the comment was more to point out that each monitor displays could a bit differently.
Photographers who edit their photos are also anal about this.
A friend who shoots professionally has a special monitor and follows a daily regime before photo editing starts to ensure the colors are to a set standard.
its all greek to me.
who remembers the shoes??? (and countless others)
