Requires an ACTIVE adapter
A passive adapter is the most basic type of adapter that can purchased. A passive DisplayPort adapter merely allows the GPU to communicate with a “language” that can be understood by the attached monitor, which has a differing connector.
As an example, using a passive adapter to connect a DVI monitor to a GPU’s DisplayPort connection will essentially cause that DisplayPort output to communicate with the “language” of DVI. As far as the GPU is concerned, it does not have a DisplayPort monitor connected, and therefore cannot leverage the benefits that DisplayPort enables (e.g. AMD Eyefinity technology).
In contrast, active adapters will actively translate the DVI signal coming from the monitor into a native DisplayPort signal for the GPU (and vice versa). A native DisplayPort signal is required for AMD Eyefinity because DisplayPort signals can be synchronized by the GPU to keep all of your monitors moving in concert.
This DisplayPort signal can also be synchronized with DVI and HDMI signals, but only two of these signals may be utilized on an AMD Radeon™ GPU. This is why AMD Eyefinity technology requires a native DisplayPort signal for the third (or higher) monitor.
