Framerate locks to 30fps with vsync enabled in eyefinity

Dell 24" U2412M
HP Omen 32" Freesync (main display)
Dell 24" U2412M

My framerates are locked to 30fps when vsync is enabled, vsync off and its well over 100fps.

before it was working fine on my r9 290x... DVI - Displayport - DVI
I upgraded to a vega and having no DVI I used 3 Displayports.

Heres the thing if I change the main display to one of the Dells it seems to work fine, a solid 60fps, smooth gameplay etc.. but there is 1 single tear line across the Omen which I cant get rid off.

Would the Omen be sending a rate/timing and the Dells cant keep up and it slighty drops under 60fps causing the fps to cap to 30?

Ive tried different driver versions. changed lots of settings in AMD settings,
reinstalled windows 7 etc..

I played around with CRU but getting nowhere. heres a pic of my default settings in CRU

This user had the same problem but I cant get the horizontal/vertical totals and the refresh rate exactly the same as when I change a value it auto changes the other

Any help would be greatly appreciated!
