Need help for eyefinity 3 screen

post #1 of 6
Thread Starter 
Hi all,

I'm trying to do 3 monitor using my Asus Radeon 6870HD, I have a problem with the third screen to find "duplicate" option under "Creating and Arranging Desktop"(look the first picture). When i try to open "Detect Display" my third screen is disabled (you can see at second picture). All of the screen work fine. I can swap around 2 of my screens.
Both of BenQ GL2450 connected to DVI and Acer G245Hq connected to Display port.

Dose any one know how to re enable my third screen?

One of your monitors needs to be connected via display port

whether it be native DP or an active DP to dvi / vga adapter

but you cannot run eyefinity with say 2 DVI and one hdmi

if it is your display port monitor i would have to say that your monster Displayport to DVI adapter is passive and not "active"

This.

Your displayport adapter HAS to be active. If it's passive, it wont work.

Here's the one I''m currently using.
