4 Monitors and a Projector with Radeon 6700/6800 series

I have two graphics cards, one is a Radeon HD 6700 series and one is a Radeon HD 6850.

Both have dual DVI ports, a display port and a HDMI port. So all up, I have 8 ports that I assumed I should be able to hook 8 monitors up to... that doesn't appear to be the case :(

I have four monitors connected up to the DVI slots, and one HDMI projector plugged in. Apparently I can't connect the projector without disabling one of my monitors which is a pain. Does anyone know of any way for me to get the projector working without having to disable a monitor? Either that or why do they ship with 4 ports when you can only use 2 at a time M_M :@ fuu.

Each of the cards can drive only 3 displays, but only it can only drive two HDMI/DVI monitors. You can use only 2 out of the 3 HDMI and DVI ports. The third monitor has to be a Display Port. To connect an HDMI adapter to the DisplayPort you'll need an active DisplayPort to HDMI adapter.

See more details at ATI's site.

Thanks for the reply. I got out a DP to HDMI adapter and it still doesn't work :? I have 2x DVI plugged in and 1x DP (via HDMI:DP adapter). Is there something else that might be restricting it? Does that mean I have a 'passive' dongle instead of an 'active' one??? It doesn't say anywhere on the box what it is :\ – Benno – 2012-02-09T04:53:53.647

It's probably passive. Does it take external power (possibly through a USB port)? If not it's definitely passive. – shf301 – 2012-02-09T16:16:34.607

Nah there's no other power source. Well that sucks, thanks for your help then! – Benno – 2012-02-12T04:52:58.027

MST hub - DisplayPort to 3x DisplayPort will allow to connect 3 more im having a similar issue and this is the fix per amd.
