Anyone manage to get this to run at 4k 60hz 4:4:4 from a pc? I've tried a myriad of cables and get results ranging from screen flickering, random flickering pixels, or simply no signal depending on which hdmi port on the tv I plug it into, but none of them just work. It seems to work fine at 30hz though.

PhrozenGhoztMake sure your HDMI cable supports high bandwidth. It may not if it's older.

dshreterYeah and if it’s further than 10 ft I’d try an active hdmi cable, got one from monoprice and it fixed my flickering and loss of signal issues

PhrozenGhoztActually I am using this monoprice cable (10 ft) - https://www.monoprice.com/product?p_id=15429
However I may have solved it just a bit ago. I ended up trying an active displayport -> hdmi adapter and it seems to be working without issues now.
