Eyefinity dual monitors and DVI splitter

[kinghippo]

Hello

I just bought another Korean 1440p monitor and a new graphics card for my pc and I'm having trouble getting both monitors to work. I bought the XFX R9 280 under the assumption that it had 2 dual-link DVI ports but that is not the case.

I was thinking about buying a DVI to HDMI cable, but I think these monitors are not compatible with the cables. The product page says

Please use DVI-D port only. may not used with DVI-I or DVI-S. Also may not be used by port converter. (D-sub, HDMI, DP) Specifications

I read on a forum that it was possible to use a dual-link DVI splitter and extend the display across both monitors with Eyefinity in the control panel. I thought that a splitter would only mirror the display and not extend the desktop across both displays.

Has anyone tried this before or know if it's even possible?

Thank you!

A splitter would just send the same signal to both monitors. My driver patch will allow 2560x1440 @ 60 Hz to work over single-link DVI and HDMI if the monitor can handle that: http://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher

Thank you ToastyX but I am mostly a linux user. I will give your patch a try on windows for sure though. It will be nice to see both monitors working.

I have a 7850, and only the top dvi port is dual link. You *could* buy an active displayport to dvi adapter though (last time I checked they were expensive).
