Custom Resolution Utility (CRU)

Hi everyone. Great respect to ToastyX. Just adding my two cents about Chinese monitor Mucai 27 inch 1440p that i bought recently. CRU name SGT2700.
It behaves very weird. Via DisplayPort Freesync is broken completely - screen blacks out in 40-50 frames and with Freesync turned ON in monitor menu monitor won't show any picture at all if set over default 75hz. Range editing trough display properties didn't give me any results.
IF freesync turned off in monitor menu it will accept 90hz easily and auto set itself on 10 bit mode.
BUT
Trough a HDMI cable i managed to get it working with freesync (my main goal) on 84hz 8 bit mode (it won't let me choose 10 bit). And what gets me is that freesync range i've got is 20-84 and it works perfectly!
But no 10 bit... Why? No idea, maybe you can help me out with that. And what gets me is that it won't let me choose any refresh rate higher than 84hz in windows.
Otherwise it is flicker-free, and it has a semi working HDR (SMPTE 2084) with auto mode but gamma is off slightly.
DCR (which i never use) and something called "LED EFFECT" which to my case did absolutely nothing
So i am pretty happy with the results. CTA-861 extension blocks did the trick for the freesync. Should i test some other settings? I wonder why different ports of that monitor work so different. Any way i can force it to 90hz 10 bit + freesync?
