crossfire/ eyefinity/ multi monitor question

post #1 of 16
Thread Starter 
next week i will be ordering 2x hd 6850 to be ran on crossfire on a crosshair IV mobo. i will also be ordering 3x 21.5 acer monitors. (no hdmi support)

so do i have to hook up all 3 monitors to the same graphics card? i.e. 2 to to of the dvi port and 1 to the display port via active display port adapter?

or can i hook up 2 monitors to the first cards dvi ports and the last monitor to the second cards dvi ports?

what the difference between an "active" display port adapter and a non active display port adapter?

thanks for any help. its much appreciated.

Sadly, no, you cannot use the different cards, so you are forced to use DP or, in your case, DP adapter.

Don't know about active vs. passive that much so I'll let others handle that.

One thing I would advise is that, if possible, aim for 24" monitors. 22" may seem too small. Especially for horizontal viewing, like web browsing, assuming 16:9 monitors.

All monitors in a single eyefinity group need to be connected to the same card



So two DVI + one DP required. You'd better buy the adapter for the DP

3x 21.5" 1920x1080 monitors is a good option IMO




Anyways. You can only connect 2 of the monitors to the DVI and HDMI slots.

The third one MUST be in the DP port.

awesome! thanks guys. i really appreciate the help in clearing this up.
matrices actually got me looking at larger monitors, and i can get 3x23" for $20 more a pop. (even though its going a little over my budget.)
i just really hate buying adapters (esp $30) ones because as soon as they get left out my son puts them in the trash can. crossfire bridges as well.

Don't worry. Just connect the adapter to your computer and tell him to NOT TOUCH IT.


PS: The adapter you buy MUST be eyefinity validated. If it is, it will be advertised as such. smile.gif

i have limited desk space and dont want to add another desk to my "computer budget" which is far beyond its $1,600 usd max. (but im buying the fiance an iMac so i dont think she will mind too much.)

/edit- but if i had to choose 24" id get these.

i just hate shiny bezels because i have a light right behind me.

@De-Zant: i would tell him that, but hes too young to understand. i usually just end up duct taping my connectors to whatever it is they are connecting lol.
