Well, it would seem so on the two monitors I've tried...VGAOnly puts the
frequency of DBL[PAL|NTSC] up to 31kHz but no luck (well, the Dell branded
17" here briefly synced on DBLPAL, albeit with the display aligned totally
wrong horizontally, but after a few seconds it lost sync.

Will adjusting the tooltypes of the drivers affect the relevant frequency
(coming from someone who doesn't *really* understand what all those things
are about)? And if so how does one adjust them to up the scan rate?

And finally what is the usual frequency used by a PC output?
