Then either you can get another active adapter or your monitor isn't like this and you just have to forget about the whole thing.

I ran into the same problem with the Displayport to HDMI converter.

If you want to run 3 monitors, one connection has to be a true Displayport signal. Whether that's a direct Displayport out from the videocard to a monitor that has a Displayport input or using an ACTIVE Displayport adapter going to the monitor's HDMI input.

As long as one connection is like the above then you can use an HDMI and DVI with it.

Did you go into the video driver and tell it to Detect Displays under Common Display Tasks?

Or Active DVI. One of the 3 ports must be DP or look like DP ("active"). I am not sure about what is needed for the 4, 5 and 6 monitor variants.

I haven't updated this in a while:

ATI Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, additional panels with native DisplayPort™ connectors, and/or DisplayPort™ compliant active adapters to convert your monitor’s native input to your cards DisplayPort™ or Mini-DisplayPort™ connector(s), are required. ATI Eyefinity technology can support up to 6 displays using a single enabled ATI Radeon™ graphics card with Windows Vista or Windows 7 operating systems - the number of displays may vary by board design and you should confirm exact specifications with the applicable manufacturer before purchase. Systems using multiple ATI Radeon™ graphics cards can support a maximum of 8 displays (total across all cards in system) with a maximum 6 of those displays being used together in a display group (also known as a single large surface mode).

Any additional monitors will need a native Displayport connection.

For example for 6 monitors you will need at least 4 with a native Displayport connection and the other two can be anything else.

There are Displayport hubs you can get that will split a single output so you can hook up a multiple monitors.
