Notes
1. AMD Eyefinity technology supports up to six DisplayPort™ monitors on
an enabled graphics card. Supported display quantity, type and resolution
vary by model and board design; confirm specifications with manufacturer
before purchase. To enable more than two displays, or multiple displays
from a single output, additional hardware such as DisplayPort-ready
monitors or DisplayPort 1.2 MST-enabled hubs may be required. A
maximum of two active adapters is recommended for consumer systems.
