Well I got my replacement Samsung U32D970 and I have the exact same flickering issue running any normal or HiDPI at the default 60hz.
I purchased SwitchResX and set a custom UHD at 56hz and all of the flickering has gone away. Great news right? Well sort of it only works at the default setting. Trying to run at any scaled resolutions (custom at 56hz) does not give you HiDPI but horribly fuzzy scaled sizes. All HiDPI are listed in SwtichResX at 60hz and you cannot create a new, custom HiDPI mode with a different refresh rate.
So my question is can you hack the EDID so OS X reads this as a 56hz monitor? I know the LG I returned is recognized as a 50hz screen. Im' guessing because Apple can't figure out how to get these SST screens running at 60hz yet.
Any advice welcome.
