Personally I do not see any reason why you could not use a decent graphics card as arbitrary wave form generator

I think there are 2 separate issues here. If you write a driver for a video card, and you write it with in mind the idea that it will be used to drive a monitor, then very likely, already in that driver, you will limit the minimum H and V pulse width that user space can set.

The next level up is then the user space program, I use xvidtune myself in X.

So one should really look at the driver code first for any range checks etc, before concluding 'the card cannot do it'.

In the DVB-T case he probably did not need zero sync width? Not sure.

Oh yes, I remember Markus. He used to post to sci.crypt and I have some of his 'eavesdropping' papers. I remember discussing PMT tail lag correction in flying spot scanners with him.

Chinese shit equipment,

you are in the category

Really. Gosh not having to be locked to a very short list of common = video frequencies seems like a good start. How about how do you get rid of the various sync times? Who knows what other limitations are hard coded into the raster hardware?
