Hi Mark - I'm using the same display. My understanding is that if you have Spectraview II installed you don't need, and there is no value-added, also having Multi-profiler. All that said, I'm not using Spectraview either. I prefer BasicColor Display from BasicColor GMbH Germany.
So BasicColor Display can correctly set the internal LUT on the NEC Spectraview monitors? How to ensure that one is really invoking the internal LUT of the monitor and how the display uniformity correction is being handled are my two continuing points of confusion. There's a clue to some of these issues in the Multiprofiler manual that states:
"Mac Users - Do not use the ColorSync control panel to switch between different monitor calibrations by selecting different monitor color profiles. Always use the MultiProfiler application to configure the display profile. This is because all of the necessary color adjustments, including the Look Up Tables, are stored in the display monitor and these must be set by MultiProfiler. The ColorSync profiles generated by MultiProfiler contain linear Look Up Tables for the video graphics adapter."
I'm interpreting this to mean that Multiprofiler and Spectraview write two LUTs, one for the monitor's "Spectraview Engine" on board the monitor, and another "linear look up Table" to null out the video graphics adaptor card in one's computer. Makes sense I guess, but it also means that one has to be sure the process doesn't get out of sync which apparently it may do if one starts playing around with the display panel options in the Mac system preferences menu.
Hi Mark S.. Perhaps BasicColor Display is also doing what Multifprofiler and SpectraviewII do, which is to update the internal LUT on the PA271W and also write the "linear LUT" for the display card, but I suspect that most other calibration software packages would undoubtedly try to treat the PA271W as just another monitor in need of a normally calibrated vgct tagged display profile for use with Colorsync.
I did manage to download a copy of Multiprofiler for MAC from NEC's website (silly that it wasn't included in the box or on the same CD that had the PC version), but I have resolved that confusion now, and indeed installed Multiprofiler successfully. Still some questions as to whether SpectraviewII and Multiprofiler have totally or only partially overlapping behavior, but one interesting thing I noted was that when I opened Multiprofiler and went to the "Picture mode" feature, there was a radio button labeled Spectraview and when toggled between other modes and back to that button, it restored the monitor calibration I had previously built in Spectraview II software. So, these two software packages appear to have overlapping integration of various functions, but it's a bit murky from the end-user's perspective, and one seems to have to really wade far into the manuals to try to make any sense of this.
