I'm bumping again:
So far all the pcs I tried, with enough power for HD animes, where with Nvidia cards and DVI.

It's frustrating not being able to try with an ATI, but whatever.

The interresting thing is DVI...
Seems like DVI hasn't been designed with lots of refreshing rates in mind. So it's 60Hz or so. Causing troubles for non multiple FPS in paning sequences in movies/anime.

To test that, I tried with a DVI to VGA adapter... I know, I go back in the history of technical progress.... but in VGA the image is still good and I can even get 72Hz refresh rate that didn't work with DVI even with powerstrip... maybe it comes from the cable, I have a much better one but installed, so it"s a pain in the ass to try that...

In VGA, 72Hz goes smoothly. VGA was designed or updated with multiple refresh rates... and now with powerstrip and reclock, although not perfect, paning scenes are so much better. Because 72=3*24...

I guess next step is a HDMI monitor (like that 21.5" FullHD viewsonic) and a HDMI card with enough power for my other needs...
Why HDMI? because if lucky, the whole loop accepts lots of other refresh rates... because the design is more open for refresh rates.

but for now vga is ok...
