This display is big. The first thing I thought was 'is this thing going to hurt my eyes?' The natural tendency is to sit further back from a display this big, to sort of put it into the right perspective in your field of view that you're expect to see. But then that sort of defeats the purpose of getting a bigger display doesn't it?

IF you've been running on a previous version of SpectraView II, you may plug this new one in and start the software. It will open normally, but won't allow you to calibrate (calibrate button is grayed out.) This is the normal condition for when the software is running on NEC monitors that it does not support. Checking for the latest software update is easy by following the link under the Help section.

Color gamut

Besides its large physical size, the 301 has a wide gamut, capable of reproducing all the saturated colors of the AdobeRGB working space.
