Damn who really cares it was a damn good thread that explains alot for everyone. To trully make this thread worth wild, this thing should be "sticky" with updated links to the the best working/cheapest adapters that will get the job done. Put out the top 5 best adapters that we need to get eyefinity up and rolling with AMD/ATI cards so we don't have to search for stuff we don't know about. One stop shop biggrin.gif Lets get them links rolling!!! I got three Catleaps that are waiting for me to purchase and i don't know which adapters to get.

Hello,
This is a great thread....

the OP had a great explanation, and I haven't had the time to verify it fully but it makes sense.

In a nutshell the away these display ports work seems is that :

1st that graphic card starts talking to the connected monitor, and it then discovers if the connected port is analog or digital, and what the specifications of the monitor are. If the monitor is accepting digital data (often don't) then the card has to transform that digital data directly, otherwise it has to convert it into a power hungry analog format.

For all those electrical engineers out there (like me) , the reality is that both signals are digitally coded, but the "older" technology (VGA DVI HDMI) has a higher current deliverance and a less sensitive receiver... think of it as LVDS. On the other hand Display Port has a smaller current deliverance and therefore needs to be talking to a smart and sensitive receiver.. think of it as Current Mode Logic (CML)...

Another big deference is that VGA is feed forward only, so the graphic card never hears back from the monitor in VGA mode. Display Port talks to the monitor and retrieves information back from it... this information could be resolution and refresh rate and also coded digital information to improve the signal integrate of the link.

So some cards actually are capable to deliver the data in an analog format from all 3 ports, because they have the power, actually all ports have the amplifier to deliver in VGA format... its just that if you connect all 3 in that format you get less power delivered to each driver, and higher chance of getting bad data received at the input... This is called Bit Error Rate (BER), and honestly,,, companies do like to sell you a $100 converter.

I have a 6 display 5870, and have had a hard time getting all 6 of them to work, even tho I have 4 active converters and 2 passive converters .... I could get 3 working with passive converters although it says that I need 1 active and 2 passive in the website. If my theory is right, then having 5 or 6 active converts should get my 6 displays working with no pain... right now it is very painful... as screens go blank and resolutions get missed up...

Hope my 2 cents helps someone out there... please correct me if I posted anything wrong... I'll report back when I get my 5th active converter and try it out.

Everything that the OP said is true

I had to find out the hard way, wasted like $300 on adapters & extensions that people claimed it works with Eyefinity, but they did not. mad.gif way back in March 2012 when i picked up my 2x 7970 DC2 TOP

In the end had to pick up 6 Accell Active Adapters, and all problems were gone thumb.gif

shall have i went that route from the beginning and i would have saved myself $300 for another type of upgrade, a new cell phone or more HDD space perhaps tongue.gif

@foothead

maybe we should make a list of working adapters that werent listed on the amd website.

I bought these two cheapo adapters because the sapphire adapter for sale in my country only came in mini DP and not standard DP size.


This did not work and is surely passive:
Encore ENCA DD http://www.newegg.com/Product/Product.aspx?Item=N82E16812340008

This is working flawlessly:
Encore ENCA DV http://www.newegg.com/Product/Product.aspx?Item=N82E16812340010&Tpk=enca%20dv

I had 3 Saphire dp-dvi adapters witch did not work with 3 displays, then changed 1 of them to a HIS active adapter and all works perfect.. This adapter was just as cheap as the passive, with no external power. If you have a mini dp i do not know, but for 3x dp you do no not need separate power, just 2x dp-dvi + 1x active dp-dvi adapter... even the cheap ones!

I'm new around and have made a lot of searching concerning the subject. Seems like the Thread maker is quite right. Now, though, am I the only one stuck up with this issue that I'm completly unable to find an active DisplayPort to HDMI adapter? I got that Samsung TV that could serve some purpose if I ever get this to work. At the moment, using my actual (most likely passive) adapter only allows me to connect two screens at the same time. ATI's website doesn't list any HDMI active adapters at all neither.

Ideas?
