Your assumption is correct.

As with others submitting to this forum, I can only use 2 of the 3 displays using passive adapters. Active adapters are available on ebay (mini dp --> hdmi (active). None seem to be available locally (Edmonton, Canada). Will such an adapter solve my problem? Or, is it worthwhile trying to use a mini dp -> DVI (active) adapter ---> DVI->hdmi (passive) adapter? will either or both solutions work?
Thanks in advance. and thanks to all who have posted very intelligibly on this post.

Either or both of those solutions 'might' work. Previously in the thread there were some people that were able to go DP -> DVI (active) then DVI to HDMI, but for others this did not work. In theory, an active mini DP to HDMI adapter would be the best way to solve your problem. However, previously in this thread it was stated that these don't/couldn't exist. On the AMD compatibility list under Active HDMI adapter it says 'coming soon,' so it's likely they could exist.

This is one such product that could be what you're looking for: http://www.startech.com/AV/Displayport-Converters/Mini-DisplayPort-to-HDMI-Active-Video-and-Audio-Adapter-Converter-Mini-DP-to-HDMI-1920x1200~MDP2HDS

If that doesn't work try the DP -> DVI-> HDMI route. Depends on if your cool with possibly wasting some money trying these adapters before buying a new monitor if neither option work out.

Good luck

Wow! Thanks for this info. I had no idea that choosing a Mini-DP -> HDMI adapter would turn into such a daunting task. I just ordered a DP to HDMI adapter (DP out from the card, into the HDMI in on my monitor) when I stumbled across this thread. Now I wonder if I wasted money on the adapter cuz it may or may not work (one Samsung monitor and one HDTV). Currently I use HDMI -> HDMI for the TV and a DVI -> HDMI adapter for the monitor. I was hoping that by getting a DP to HDMI adapter I could route audio through the monitor the same way I currently route audio to my TV.

It is very frustrating that the industry can't get on the same page and everybody thinks they have to make their own proprietary I/O ports, and complicating everything for the consumer in the process. mad.gif

You may want to read this article. Seems like the standards are being upgraded:

Why would that be "easiest"? I found a HDMI converter for $20 but the DVI converter is $30.

Hey guys, I have a noob question about displayport and the signals.

So apparently I have an active HDMI to Displayport adaptor(?) It looks like the active one in the OP, except with an HDMI output.

Would I be able to use this to connect my video card (HDMI) to my monitor (displayport)?

I would really like to bash this thread for being so fluffy and useless... but I don't have any better sources. You have the best... little bit of knowledge on this! So I'll try to summarize.

From skimming there are a couple posts that imply DP to HDMI exists and would work and be cheaper and I ALMOST bought one of the ones linked earlier for less than $20 but after reading a review closely I find its "not compatible with Eyefinity" so it looks like I'm getting the $30+ one.

Why is it so hard to find information for display port + adapters + eyefinity? Just not looking in the right places?

Get this, after hours of shopping its hands down the cheapest in the USA after shipping (free). Almost a full half price of the next lowest in this thread that will actually works. Note: it is for VGA monitors or if you have a DVI-VGA dongle as well for DVI monitor. (realize that can potentially be a downgrade in quality so research it more) http://www.ebay.com/itm/DisplayPort-to-VGA-Converter-Cable-Adapter-With-Latch-Male-Female-active-adapter-/120967901087?pt=Travel_Adapters_Converters&hash=item1c2a3faf9f
