eyefinity hdmi question - Page 2

post #11 of 16
This is the way it works: you have to have an active adapter if you do not have at least one monitor with a native displayport connection. Your card has 2 x DVI, 1 x HDMI and 2 x Mini Displayport connections. To run all HDMI from the back of the monitors, you will need 2 HDMI to HDMI cables, 1 passive HDMI to mini displayport adapter, 1 HDMI to DVI cable and 1 active DVI to mini displayport adapter.


This is the active adapter

Passive HDMI to Mini Displayport Adaptor

HDMI to DVI Cable

If your monitors all have DVI connections on the back, I would use all dvi's. Two straight to the back of the card and the third to the active adapter. This is the most cost effective. I've seen it both ways and couldn't tell a difference. The DVI's are just plug and play. The setup I saw with all HDMI's had to use the overscan feature in Catalyst Control Center. The picture wouldn't fill the entire 1900 x 1200 resolution so there was black bars encompassing the desktop on the screens. Overscan allows you to adjust the screen so the entire resolution is filled with the desktop. It can be worked out, it's just an extra step after reinstalling drivers. The setup eventually went to all dvi connections since there was no difference. The monitors that had that setup were Samsung Syncmasters I believe. 1900 x 1200 resolution with tv tuners.

Not sure what you plan to use the eyefinity for (gaming I'm assuming). As far as FPS's (BF3, BC2....etc), you will probably want to consider crossfire. A resolution of 5760 x 1080 is really taxing on a system. You will see your frames drop considerably at much lower video settings. Ask any eyefinity user.

Anyway, HTH

To answer your ? directly, no. You have to have an active adaptor in there. AMD cards only have enough power for 2 active ports at a time. The third has to be via an active adaptor.

Not really sure why you keep referring to Eyefinity and 1080p together? The links listed above will allow you to combine resolutions of your monitors into an Eyefinity setup.

Yes it will work. Why you would want to use HDMI only is beyond me, but yes it will work. your going to spend quite a bit in adapters though.
Also OP your grammar is absolutely horrible..

Repost.


HDMI-HDMI-HDMI

IF ALL MONITORS ONLY HAVE HDMI, WILL NOT WORK FOR EYEFINITY REGARDLESS WHAT ADAPTERS YOU WANT TO USE.

The only configuration that will work is #3 or #4.

The first/second monitor to have native DVI, VGA and HDMI.

The third monitor has native Display Port, else, must use Display Port to DVI or VGA Active Adapter.
