It’s important to remember that it’s not just the form factor (physical shape) of the DisplayPort (DP) and DVI connectors that are different, the electrical display signal is very different as well. Passive adapters contain nothing but connectors and cables. They do not change the electrical format of the signal in any way.

A large number of applications and games will work with Sapphire ATI Eyefinity technology, some of them are listed here. Assassins Creed, Age of Conan, Batilefield 2142, Batileforge, Call of Duty 4 Modern Warfare, Call of Juarez: Bound in Blood, Crysis , DiRT 2, Half-Life 2, Harry Potier Half Blood Prince, Star Wars Batilefront, Tom Clancy's
H.A.W.X…….and many more.

In the case of Eyefinity across three monitors, all of the possible DVI signals are used up on the other two DVI or HDMI (HDMI video signals are the same as DVI signals) outputs so the board can only output a DP signal from the DP connector. Passing this signal to a DVI monitor (by using a passive adapter) will not work as the DVI monitor will not be able to interpret and decode the DP signal to create a picture. Sapphire Active DisplayPort to DVI Adapter changes the connector form factor and corrects electrical signal to the third DVI monitor
