I have found that man pages are designed for the expert who needs a refresher
which is not the same as a noob with no knowledge. So man pages are a last
resort for me.

THANK YOU (deliberate use of caps!) - - - - this is the one thing that man pages
seem unable to do - - - - an example of good usage.

following is one example of the output:
# videogen -v nvidia=on mode=3840x2160 -mdc=300.00 -mhf=67.500 -dvf=30
argument 6 (-dvf=30) has an invalid parameter
command line syntax error
I tried both with nvidia on and off, -dvf from 25 to 35 (clock/x*y).
It would seem that I've struck out - - - - one more time - - - oh well.
I think the wife will be overjoyed at getting a new TV except that I likely
won't be getting a new monitor for quite some time!
Thanks for the help!!
