Is there any difference between using an ICC profile or the colour setting in NCP? I have good results using NCP 0.65 gamma and a touch of digital vibrance however wondering if there is any reason if I should use an ICC profile and Windows monitor calibration tool instead?
Simple answer... no.
If the visuals suit you, then job done
Basically, there's no plug and play set up for every monitor. What works well with one, will look pants on another (maybe). This is before considering the expression "personal preference". As I've already said a few times on this thread... I've seen monitors set up so that the user loves it, but to me it looks pants. But if the customer is happy, that's all that really matters.
Maybe a different matter if you were using the monitor for certain professional reasons. But then again, I'd not be choosing this monitor if I was a graphics artist.
