Andrew,
Thanks for your reply.
1) I wouldn't know where to look for the crash log. Nothing obvious in the SpectraView menu items.
2) I assume you meant the i1 Display Pro is supported by SpectraView? I didn't think to check before, but I see now on the SpectraView web site that the i1 Display Pro color sensor is supported.
3) & 4) I was afraid of that, and yes, the DDC_CI bit is is mixed bag--fine when it works, but a show stopper for SpectraView when it doesn't or isn't accessible. Unfortunately, I don't have the DDC_CI link accessible via my laptop , which is my best computer. My desktop (core 2 duo) has DDC_CI link through the dual link DVI cable and I can use SpectraView, but the desktop suffers from very slow responses in LR4. I would like to use my laptop (i7, 8 cores, 16 GB ram) with the NEC display for LR4, but Spectraview (DDC_CI) isn't supported through the available ports as discussed in the link given in my previous post. I was hoping that a i1Display Pro puck, together with the i1 Profiler software on my laptop would solve all my problems, but alas--apparently no such luck.
I guess I will have to keep looking for a solution.
