I agree with both Don and Borries good advice.
A third case is the monitor has failed or is failing.
I got that "Out of Range" message frequently after every reboot. It
was worse with some Linux OS's than others.
The monitor did not work at all with some Linuxes even after manually
setting the "xorg.conf".
I assume this is due to different ability levels of probe software.
For example, that monitor works fine on Windows. Go figure?
That monitor is now retired.
