Will,
I have been using SpectraView version 1.1.05 that came with the monitor. It just so happens that version 1.1.07 was added to the download site yesterday 11/15/10. Unfortunately, when I gave it a try there was no difference. I found the note you mentioned in the readme file for this version.
Nvidia video drivers "No Communications":There is a known issue with the Nvidia video drivers versions 260.xx that prevents SpectraView from communicating with the display via DDC/CI. If you experence a "No Communications" error when using an Nvidia video chipset, try downloading and installing an older version (prior to 260.xx) of the drivers. Nvidia is aware of this issue and is expected to have updated drivers available soon. If you are using a MultiSync PA series display, please connect a USB cable from the host PC to the display to avoid this issue.
My monitor is not a PA series and so it sounds like I may have to wait for Nvidia to update their driver. I'll keep experimenting and checking both the nVidia and NEC sites. Thanks, Craig
