Thanks for the reply.
However I believe the screenshot you showed is actually showing what the display is currently running at, as opposed to all the of resolutions it supports.
Also, for this particular monitor you can find people on youtube who run it fine without multi-stream on macbook pros.
I used switchresx to get the EDID info that the monitor is reporting.
Sadly I'm not fluent in the format, however to my untrained eye it does seem to list Mode = 3840 x 2160 @ 30.000Hz
Here's the whole thing for anyone interested.
