I have not had much time to see if this fixes the problem. In what I came
across on my own prior, this was one of the rabbit trails I went down, but
did not pursue. Being as I am new to linux and not super proficient at
installing and running these things, it takes me more time to do the simple
task such as installing or running different types of programs. The
instructions for read-edid weren't quite as simple for me as I'm sure they
are for most. Lol. I did start on them, but I'm not quite there yet. I
will keep you all updated as to my progress.
Thanks for your help.

AHAH
http://john.fremlin.de/programs/linux/read-edid/ Found a fix
to summarize:
Nvidia GPU is unable to read the Extended Display Identification Data for
the tv, defaults
to nvidia-auto-select. by reading the EDID at the hardware level and placing
this information in the Xorg.conf , a match to device capabilities will make
it work.
