A4k Graphics card question.

[Castellen]

I don't think the Retina card can pick up 15kHz native video modes and scandouble them?

An (expensive) soloution would be to use a PicassoIV card, which automatically pick up and scandouble all motherboard video, including the early boot menu, etc.
This means that in theory, you can use almost any "PC" type monitor to see all video modes, without using any kind of additional switch boxes, flickerfixers, scandoublers, etc.
I have a 15" Mag LCD monitor on my A4000 with the PicassoIV and it works great.

Beware of some LCDs which refuse to display scandoubled video, even though the signal is within their input specifications.  I had an early Philips monitor which did that.

Or with a couple of PicassoIVs fitted, you could have DOpus in a P96 screen, and Voyager on a seperate monitor and P96 screen :-P

Could you actually do that?  I'm not sure how the keyboard and mouse input would go.  Surely you could only select one at once??
I have two PicassoIVs here and two video slots in my A4000T so thought about trying it once.  Though the P96 software setup would be crazy!
