So, I'm wondering what is a good white luminance target to calibrate my monitor to. It's a Dell 2209WA.

A quick search shows me I should aim for 100-120 Cd/m2, but the poster (on another forum) does not say exactly why.

What is the thinking behind this? White luminance dependent on ambient? So if my room is bright, I should aim for a higher luminance setting? What's the tradeoff for a too-high white luminance setting? Too low?

What about black luminance target?

Anybody come across a good site that explains these issues clearly?

Thanks!

I have my monitor calibrated to SpectraView's recommended 120 cd/m^2, D65, gamma 2.2 target. I would guess that this is a very standard setting. If you are working in dim lights, you could probably get away with a little less luminance. I know that my EyeOne Match software recommends 90 cd/m^2 for laptops.

yes, your luminance setting depends on ambient light. The higher the ambient light, the higher the luminance.

The thing is paper is only so bright and you can't increase luminance for paper.
