yes you can, and yes they will update in real time. just remember to switch off the pass through option.
but as said before, you can't spead workbench over multiple monitors.
however, if you are running one of the mac emulators, you could spead the mac desktop over as many monitors as you liked. even aga/gfx combo. had it playing back .mov's in 'widescreen' across aga and a cvppc. kind of watchable as the updates were out of sync, but an interesting exersize anyway.
back when i had an A4000T, CSPPC, CVPPC, CV64/3D, Vlab Y/C, ardaine ethernet, AD516, Digital Broadcaster32. stack of ram, stack of ultra scsi hardrives.
sold the lot for 800 GBP. stupid stupid stupid. someone hit me. :lol:
