AMD eyefinity refresh is stuck at 60Hz

[Admetos]

I'm running AMD eyefinity on a R9 290 card. My 3 monitors are capable of 75Hz refresh rate however eyefinity is only allowing me to select 60Hz.

The screens are identical in model, they will run at 75Hz but only without eyefinity.

Any suggestions as to what to try.

Thanks
Jason

Old gamer,

I'm using 2 x DVI + 1 x display port, I'm pretty certain this is not the issue.

If I disable eyefinity (run 3 regular screens) they can all run in 75Hz, it's only when the monitors run in eyefinity (as 1 large screen) i'm restricted to 60Hz.

What monitors are these?

Are you overclocking them to 75hz or is this a standard refresh available to them?

There Ag Neovo e19w.

It's not an issue with the monitors as they all run 75Hz without the eyefinity, 75Hz is a standard refresh for these screens.

Also when I run the monitors on Nvidia Quado cards using mosaic (quadro's version of eyefinity) all 3 monitors run 75Hz.

Checked a few things but still stuck.

Does AMDMatt know by any chance?
