How to use eyefinity
Solution 1:
Eyefinity allows you to drive up to 6 monitors using a single GPU. You can either run applications which span multiple monitors, or use each monitor separately. Note that you need a dongle if you want to drive more than two monitors from a single Eyefinity-compatible video card. AMD has a list of supported dongles.
Requirements (quoted from AMD's website):
- ATI Radeon 5400 or higher
- Driver version 8.66 (ATI Catalyst ™ 9.10) or above is required to support ATI Eyefinity Technology and to enable a third display you require one panel with a DisplayPort connector.
- ATI Eyefinity Technology works with games that support non-standard aspect ratios which is required for panning across three displays.
- TV Tuner required, sold separately.
- Linux support scheduled to be enabled via a future ATI Catalyst™ driver release.
