Monitor works fine with old computer.  It just doesn't like my new 
computer.  Maybe it thinks it should retire.  It is pretty old.  lol

So far, I have tried different cables, different cards and just plain 
unplugging it to let it "reset" if there is anything in there to rest.  
Still doesn't work.  I didn't know 2" of monitor made such a 
difference.  o_O

I also tried resting the BIOS in the new puter and booting too.  Still 
nothing.

Any more bullets?  I been looking for a new monitor but I'm not sure 
that will work either.  Be bad to buy a monitor and it not work for some 
reason.

I'm going to shutdown for a while and see if that helps.  Just pull the 
plug to the power strip from the wall.
