u can use the third output via ATI eyefinity mode... all u need is Driver version 8.66 (ATI Catalyst ™ 9.10) or above is required to support ATI Eyefinity Technology and an ACTIVE!!! DP to DVI or HDMI or VGA dongle on the third output (the first two can be regular passive adapters)... u can get one on amazon.com..Tschoepler wrote:ridiculoid wrote:3 outputs on each card (2 x VGA and 1 x either HDMI or DisplayPort)I have a 5770 and the new Radeon cards support 2xDVI not VGA (of course you can connect an adapter). Furthermore they only support 3 displays if the DisplayPort is used. So you could connect either 1xDVI 1xHDMI 1xDP or 2xDVI 1xDP. 2xDVI 1xHDMI won't work!

There is a new variation of ATI 5870 called Eyefinity, it has 6 mini DP outputs , 2x DVI or 1x DVI+HDMI or 2x VGA can be used with regular passive adpaters and the rest must be active
Connectivity Requirements: ATI Eyefinity technology is supported by graphics cards in the ATI Radeon™ HD 5400 series and higher. These cards can support up to six monitors (depending on the model), subject to the following restrictions:
• A maximum of 2 legacy monitors (VGA, DVI or HDMI) can be enabled simultaneously, provided that each monitor is connected either directly or via a “passive” DisplayPort™ adapter/dongle. “Passive” adapters/dongles will NOT support more than 2 legacy monitors.
• To enable support for more than 2 monitors, “active” DisplayPort™ adapters/dongles are required (or monitors with direct DisplayPort™ connectivity must be used).
• Approved “active” adapters have no general connectivity restrictions with ATI Eyefinity technology.
