Yes, I think the colorwiki link was referring mainly to printers, is a bit misleading (my bad to include it here). Is the same discussion as with the driver: in principle the graphic card should not affect the colors that are sent to the monitor, but graphic cards can be so different between them that in practice it does matter. Same generation of the same vendor may be OK, two completely different GPU is probably not safe. And yes, color temperature is very important: the profile tries to match the color temperature you ask for, so a profile with a target of 7600K will look a lot bluer than one with a target of 6500K. You probably want 6500K, as that is the standard for monitor viewing. Brightness is also important, to a lesser degree. > There are just a lot of options in Display Cal and even there is > documentation - some areas are lacking detailed explanation for a beginner. Yeah, it also took me a while to understand which options to use, and even after deciding I was second guessing my configuration all the time. I'll post tonight the options that I found the most "sane", maybe it's helpful for you as a start point. If I find the time I'll try to also write a small walk-through of what I did when I calibrated my monitor (including the color temperature options).
