6850 wont run 3 monitors. Even with active DVI -> DisplayPort

post #1 of 3
Thread Starter 
Hi all, Im trying to get my 6850 working with 3 screens.

Monitor A has DVI, VGA
Monitor B has DVI, VGA
Monitor C has DVI, HDMI, VGA

The 6850 has a DVI-I, DVI-D, HDMI, and a DisplayPort

I know I need to use DisplayPort to use the 3rd screen, and if using an adapter for the DP, it has to be active.
So I bought this active DVI to DP adapter: http://www.ebay.com.au/itm/390615062788?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

However, However, when I plug in my DVI-D (Single Link) monitor in to the adapter, nothing is displayed. The monitor does detect a signal though, as it displays a check cable message when I unplug the cable. It is the same for all monitors.

Is the unit defective, or do I need a DVI-I cable?

Adapter could be bad... people have had problems with them. Don't know anything about that specific model but I would start there.

Remove all dvi cables and just leave the display port cable.
If it works when its alone, that means its not active.

The one you bought looks like an Encore DP to DVI adapter, i know for sure they are passive since ive bought one.
Right now im using Encore DP to VGA adapter, its active.
All DisplayPort to VGA adapters are active because the digital signal is needed to be converted to analog.
