Sell your current i1d2 and buy the PA241w either with - the full SWII package (software + sensor -> the NEC branded handpicked i1d2 one) OR - the SWII software (without the NEC branded sensor) and a "retail" X-Rite ColorMunki Both sets should work well. The NEC branded sensor may works a little bit better on the given NEC display (spectrophotometers can be weaker on dark measurement) but a ColorMunki is a more useful instrument. Your choice. If you don't have enough money for the full package (display + complete SWII package), I think you should pick up the display now and use it with the factory settings until you will be able to buy a SWII soft + CM or a full SWII package. And you can do some experiments with ArgyII until then: You can measure the display with your i1d2 and compare the results with the manufacturer's report to calculate a custom correction matrix. -> Not the best solution as Argyll can't program the internal LUTs...
