Eyefinity Questions / Help Required

[Peter929]

Hi All

Looking for a bit of guidance reference an eyefinity setup,



My current hardware =


i5 2500K based system with 2 * 5850's running in crossfire.

These are both matching "MSI ATI Radeon HD 5850 Twin FrozR II 1024MB GDDR5 PCI-Express Graphics Card" and each card has the following outputs:

1 * Dual-Link DVI-I
1 * HDMI
1 * DisplayPort

The screens concerned are

1 * 30" Dell 3011 (2560 * 1600)
2 * 20" Dell 2007FP (1600 * 1200)

Currently the 30" is in the middle, with a 20" in portrait on either side, the below pic is not mine, but my setup is essentially the same.

Reference Eyefinity across all 3 screens,


1. Using crossfire, can I only connect screens to the "primary" graphics card, am I correct in believing that the outputs on the 2nd card are not active?

2. Can I run crossfire across 3 screens (to play games) which are not all the same res, I noticed on the ATI site the following (Im hoping this is not correct / out of date / there is a way to get round it)

Can I support different resolutions?
All monitors running in a Display Group or cloned modes must be running with the same resolution. If monitors have different native resolutions, the highest common non-native resolution between the monitors will be used when creating Display Groups. Monitors running in extended desktop mode can have independent resolutions.

3. If I can run eyefinity across all 3 screens, am I correct in beliving I will require an active DP -> DVI adaptor? (The question here is more passive or active adaptor)



Your thoughts / comments welcomed...........

1. You are correct, all monitors must be in the primary card
2. Again, that is correct, they must all be on the same res when in eyefinity, and they prefer to be @ native resolutions so better to get 3 monitors that have the same native res
3. Yup, correct again, an active DP is required, but not always an adaptor as some monitor have DP on them.

Cheers for confirmation, pretty much as i thought


Is there no way at all to force a game full screen across all 3 screens?

in what way? you mean at a lower resolution or without a DP connection?
if the first then yes, you can run it at a lower res so it will work, but the quality wont be as good as monitors like to run at their native res. if the second, then nope, you need an active DP connection somewhere in the setup, be it in a monitor or adaptor.
