John,

"Input signal out of range" errors are common with LCD monitors and can
be the result of several issues, but almost certainly it will boil down
to vertical and horizontal sync values.

At what point did the problem start?

If you got through installation, we can probably fix it right away.

What are the horizontal and vertical sync values for your monitor?
