As I'm still contemplating getting a new monitor I'm curious if you have experience with Spectraview software playing nice with other monitors than NEC and other calibration solutions, in particular a Colormunki Photo that I have. I've read I have to disable the Colormunki while Spectraview runs its calibration but that's about it.
The reason I'm asking is because yesterday, having nothing better to do, I installed DisplayCal and played with calibrating my monitors for a while to see if the new 10-bit made available with the NVidia studio driver would make a visible difference. A little slow (requiring too many self-calibrations of Colormunki in the middle of the profiling) but seemed ok. Then I wanted to run the Colormunki with the X-Rite software but it wouldn't detect the colorimeter anymore. I figured it out that DisplayCal (or Argyll to be more specific) replaced the driver for it so I had to uninstall it and reinstall Colormunki (in retrospect this last part I'm not sure was necessary). At the end I can't say I've seen a significant difference between the calibrations even as DisplayCal was making me play with the monitor color settings to get a nice starting white point.
I'll still have another monitor that will need some degree of profiling even if I get the NEC so that's why I ask.
PS. what I liked about DisplayCal was that it was showing me the graph with the gamut coverage and I think I know now why the cheaper 4K monitor looks more towards blue while my older HP is more towards green (relative to each other). At least they are consistent; for whatever it's worth I'm attaching the profiling reports.
