Connecting multiple monitors for AMD Eyefinity technology couldn’t be simpler. There are four easy rules to remember:
The first two monitors can connect to the graphics card with any display output on your product: HDMI, VGA, DVI or DisplayPort.
The third (or greater) display must be connected to the graphics card via DisplayPort.
If your monitor does not have a DisplayPort connection, you will need an inexpensive active DisplayPort adapter for it. DVI to DP adapters can be had for less than $30 USD.2
Every family of GPUs supports a different maximum number of displays.
Remember that these are the most basic requirements. Creative designs like the Sapphire FleX HD 7950 or the MSI R7970 Lightning make it even easier to configure AMD Eyefinity technology by reducing, or even eliminating some of these requirements for AMD Radeon™ graphics products. In that respect, always make sure to carefully explore these non-reference solutions and their product specifications when configuring a system with AMD Eyefinity technology.
