Well, here are some ways you could simulate a specific smaller gamut display on a larger gamut display.
First, you will need to get profiles for both displays. The wide-gamut display - the one you are going to use to simulate the TN monitor - you just need to calibrate and profile in the normal way (with a hardware device - Spyder, ColorMunki or whatever). The narrow-gamut (TN) monitor, you need to calibrate and profile that too, in order to create a profile, which you save.
Some options now:
- If you have software capable of soft proofing (e.g. Lightroom, Photoshop etc), use that in soft proof mode for your test image, using the wide-gamut (calibrated and profiled) monitor, and specify the profile you've created for the narrow-gamut TN monitor as the profile to simulate.
- Use Photoshop or other software and convert your test image to the profile you've created for the narrow-gamut TN monitor (and see how it looks on your wide-gamut display).
Is that the sort of thing you mean?
Your last post was not very clear:
- By "why can we map a..." I assume you mean "how can we map a...".
- When you say "...where can display exactly same color on both monitor..." well, the way you get exactly the same colour on two monitors is simply to calibrate and profile them, and use colour managed software.
Sorry if I'm not correctly interpreting what you are saying. In that case, perhaps you can explain more the purpose of what you are trying to do, to see if I can understand it that way.
