Hello, and sorry if this is in the wrong section.

I recently switched from an Nvidia setup to an AMD one, and I'm having some issues with my 4K monitor (ASUS PQ321Q) on the new rig. I can get it to work in SST, but when I switch to MST mode I get a maximum resolution of 1650x1050.

I've tried setting it up with Eyefinity (which is why I'm posting this here), but after creating the display group I get a weird setup with two duplicated 1920x2160 screens and no options to extend the displays rather than duplicate them. Windows' 'Screen Resolution' menu has no such option , and [Windows key]-P doesn't fix it either.

I'm using the latest drivers, Catalyst version, etc. I'm not using any DVI-displayport or HDMI-displayport adaptors; it's just a minidisplayport-displayport cable.
