Thanks for your input...
2. SVII is an excellent profiler, and it allows to utilize the whole potencial of NEC x90/P221W. I use i1pro to calibrate NEC panels and it works like a charm
3. i1pro is supported by SVII so yes it'll calibrate the NECs
So, absolutely no difference is using the i1Pro or the NEC puck so long as I use SVII software?
5. 2690WUXi is larger, has higher resolution, higher bit (12) LUT, electronic uniformity compensation and H-IPS A-TW panel with slightly wider gamut. P221W has only 10 bit LUT, no uniformity compensation and S-PVA panel - in practice it doesn't calibrate as good as x90 NEC series panels.
WOuld you say the P221W is a step above the quality and capability of the Apple 24"?
Is there a huge visible difference in 10 bit LUT v. 12 bit? What is the visible difference in S-PVA panel v. H-IPS A TW?
THanks again for your help! I'm trying to stretch dollars but I do realize you typically get what you pay for. I just trying to prioritize this need with many other equipment needs.
