If you have a standard Pal/NTSC TV there is no need to worry, these sets
simply can't sync to anything other than 15 kHz Horizontal and 50/60 Hz
Vertical. The input circuit and sync separator will ignore anything
other than those frequencies.
With Plasma or LCD TV's you need to check the manual for the correct
frequencies/resolutions. They won't break if you get it wrong but you
may try for hours fiddling with dotclocks, horizontal /vertical sync
polarity and such just to get something on screen...

Most important is that you set your TV standard right (PAL/NTSC) and
setup your TV output for Composite/SVHS/whatever it needs.. :-)
