Thank you Mike and Terry.
Now it's clear about CRTs.
Still not exactly with LCDs! :-)
I have one typical office LCD - Acer AL1714. I have played with it and my
i1. Acer have controls over RGB guns, and changing them I get changes on
color temperature in PM measure tool!
Does white point on LCDs can be adjusted with such RGB controls, or white
point only depends on backlight?
If you say that LCD native white point="it is what it is", what changes
these RGB controls?
regards,
bebris
