I read your post. You may already know about this program, 'BelArc', but, if not, there is a software available for 'free' download that will identify "everything" in your computer, monitor, drivers, etc. etc.
I use it and have verified through various spyware programs, it does not seem to be spyware or malware or virus. I think it is a great program. The site address for download is:

Glad you fixed your display problem.
