doesn't mean it read correctly :-)  That's the problem with my monitor.

I have had this "invalid" mode problem also.

I had to fix it using a hardcoded modeline in the config file.

Unfortunately for the OP,  I can't remember how I determined the
modeline, but I seem to remember simply cutting and pasting it from the
auto-detect modelines.

I pasted in a modeline X claimed wouldn't work, and it worked
perfectly.
