according to your article linked
Also, it is my understanding that in the near future you will NOT need an active adapter to output through DP to DVI or HDMI.
when is the "near future"?
For those that wants to know I been at it for like 2 or 3 hours swaping ports/adaptoers/cables.. vga,hdmi,dvi.
Here's my finding:
- no matter what combination I only get two screens/display. it seems u still need a active DP adapter (or a DP screen) for triplehead to work.
- the DVI ports.. u can use a VGA adapter on it and it will work.
- u can use a HDMI->DVI cable/adapter and it will work.
I got two new spare Dell 2408wfpb a02 here that have a displayport. I'm gonna set it up and see how it runs.
be back in an hour or two.
