z32x Displayport Bandwidth Usage

HP Recommended
Dell Optiplex 9020
Microsoft Windows 10 (64-bit)

I'm trying to run two monitors from a single Displayport (DP) output on a Radeon R5 240 with a DP hub. One is the Z32x Dreamcolor and the other is a Dell Ultrasharp 34in. I had to install the original Dell drivers for the GPU as the latest software from AMD is a pale comparison to the older CCC software. The original AMD software had a Displayport monitor that shows the Z32x using 94% of the DP bandwidth, changing any of the settings on the monitor doesn't seem to affect the amount of bandwidth that it uses. Is there a setting that I am missing with the Z32x that will allow me to drop its bandwidth usage below 50%? by comparison the 34" uses 46% of the bandwith when plugged in.

Do you use the Z32X with a 4K definition or 60Hz frequency?

Yes, we use the z32x at the recomended settings. We did try lowering the resolution and/or changing the Hz but that didn't seem to affect the bandwith usage at all. We did end up buying new video cards to bypass the issue.
