MSI R7770-PMD1GD5 3 outputs? (active/passive adapters)
I have an MSI R7770-PMD1GD5. It has three output ports. DVI, HDMI, DisplayPort (using a DisplayPort to DVI adapter). However, I couldn't get it to have all 3 outputs enabled at the same time. Only two at most. Tried under both Linux and Windows.
After some research, it seems that I might need an active DisplayPort to DVI adapter. At this point I could only assume the adapter I have is an passive one.
I'm rather new to AMD/ATI cards and DisplayPorts. Is it safe to assume an active adapter will solve the problem?
Yes, an active DP adapter will solve that issue. It's also what the 3-output cards have inside, like the Sapphire Flex.
For the record, I bought an Astrotek Active DisplayPort to DVI adapter, and it worked.
It's funny how this active adapter looks almost identical to the one I already have before which doesn't work, presumably a passive adapter.
I'm only running at 1280x1024 though. I was told that for a resolution that requires dual-link dvi, I may need a powered active adapter (those with an extra USB plug for power).
What about 4 or more outputs?
Just wanted to bump this up a little.

I read about displayport multistream hub, but they are not on the market yet (and will probably be pretty expensive too?).
Are there other ways I can do this?
