There are many monitors that can be damaged by using wrong and non-standard modes, so better make sure that it will power-off if an invalid mode is tried.

Note that when the initial set of Modeline has been generated and you run X, you can use xvidtune for fine configuration. Using xvidtune's 'auto' mode, you can find the best working timing values, than you can hit 'show' to dump them to the console and replace the values of that Modeline with the dumped numbers." 20 60
