Isn't Sync to Vertical Blank enough? That should rate limit it to
screen refresh rate. Or would you really want to go lower than refresh
With flat panels you can in theory go very low in refresh rate. I have
not experimented with it myself, but I do not know of any reason why
e.g. 30 Hz refresh rate would not be possible. Unless frequency
generators cannot be adjusted that low...
Of course with CRT this is impossible due to flicker.
Might also require custom modelines.
