Can an LCD display be damaged by the wrong display output?

The monitor doesn't work with either the analog or the digital cable and
I've used the cables with other computers and they work. I've tried
three computers and there is no display plus I cannot bring up the OSD
menu. So I guess I'm stuck with #3. I've checked and the monitor has a
3-year warranty with another year left so I'll try to have it repaired
under warranty.
