Posting this in case anyone has this same issue and finds their way here through a search of the forums or through something like a google search. Needed a new computer and decided to "build" my own. Using a Gigabyte motherboard, latest intel 6th generation chip, NVidia 900 series graphics card, on windows 10. Got passed the point of getting the operating system set up so one of the first applications I installed was NEC spectraview. When it opened, I got an error message that it could not communicated with the monitor. Found my way to a post from this forum from like 5 years ago which suggested to uninstall the NVidia drivers (I went into the control panel and uninstalled about 5 NVidia programs), reboot and let windows find the native NVidia drivers.
Worked for me! Opened spectraview and everything was good to go.
