At least not fatal (they had to operate).

 From what I know you should always use a refresh rate of 60 Hz.

LCD's only work at 60 Hz and up.

An oscilloscope is the most obvious (I can borrow that). a test machine 
(I am currently using my "production" machine which is very restrictive) 
Another is test equipment that shows the different sync values (a bit 
expensive =)

If I am able to measure the sync values I might be able to deduce how 
the different parameters effect sync (H + V) and hopefully fix it.

Anyway none of this will happen before I get myself a place to live.
