Quote from Scataphagos:
I don't know specifically about the V4900, it's new.
However... usually when there are "3-ports of 2 different types", that's to accommodate only 2 monitors... using the ports however fits.
When the card design expects the user to run 4-monitors, all 4 ports are usually the same... 4, DP, or 2, DMS-59, or that quad-port thing the NVS 420 has.
If I were you, I'd check further into trying to run 3 monitors from the V4900 and see if there aren't conditions/limitations, if possible at all.
some of your assumptions have not been for a long time, lastly... from the vendor site...
