More Display Possibilities for Eyefinity


While Eyefinity may not be used by the majority of gamers, the few who use three or even six monitors compose a demanding group of enthusiasts. Unfortunately, in the past, using a single card for Eyefinity purposes either limited output options since the mini DisplayPort connector needed to be part of any monitor grouping. This meant either using a DisplayPort-equipped panel, buying a HDMI / DVI to DisplayPort adaptor or waiting for an Eyefinity version of the card to be released.


On all new R7 and R9 series cards, a user will be able to utilize any combination of display connectors when hooking their card up to an Eyefinity grouping. While most cards wonít have the horsepower necessary to power games across three 1080P screens (the beastly R9 290X and R9 290 will likely be the exceptions to this), the feature will surely come in handy for anyone who wants additional desktop real estate.

These possibilities have been applied to lower-end R7 series cards as well. This is particularly important for content creation purposes where 3D gaming may not be required but workspace efficiency can be greatly increased by using multiple monitors.


Most R-series cards will come equipped with two DVI connectors, a single HDMI 1.4 port and a DisplayPort 1.2 output. While there are a number of different display configurations available, most R9 280X cards will come with a slightly different layout: two DVIs, a single HDMI port and two mini DisplayPorts. In those cases, AMDís newfound display flexibility will certainly come in handy.

While weíre on the subject of connectors, it should also be mentioned that the R9 290X and R9 290 lack the necessary pin-outs for VGA adaptors. It looks like the graphics market will finally see this legacy support slowly dwindle down with only lower-end cards featuring the necessary connections.


For six monitor Eyefinity, the newer cardsí DisplayPort 1.2 connector supports multi-stream transport which allows for multiple display streams to be carried across a single connector. This will allow daisy-chaining up to three monitors together with another three being supported by the cardís other connectors.

The DP 1.2 connectorís multi streaming ability also allows MST hubs to be used. These hubs essentially take the three streams and then break them up into individual outputs, facilitating connections on monitors that donít support daisy-chaining. After years of talk, thereís finally one available from Club3D but its rollout in North America isnít guaranteed.
