Re: [colorvision_group] Spyder2 - highlights problem

2007-02-26 by Florent Thouret

It's not spyder2pro, not spyder2express, it's spyder2. I can't say it
in another way.

Also, I forgot to say I set both screens to default settings before
calibrate them.

in the infos window, I have (my translation can be wrong) :

screen type : LCD

Gamma : 2.2
White point : 6500K

Luminance mode : visual
black luminance : na
white luminance : na

I've just asked my father wich screen settings I used on its system :

luminosity : 80
contrast : 90
RGB : 70 57 94

Mines are :

luminosity : 85
contrast : 95
RGB : 32 22 97

Big big differences in RGB...

So, just to see, I used the same settings as I used on its system...
the spyder2 measure this :
0,336, 0,354, 165,8, 5343K

I am far from 6500...

Is it a problem from my monitor ?
