A question for those of you with a nMP and a 4K monitor:

Do you always get smooth 4K playback ?

On my system (D700s) I get smooth playback sometimes, but too frequently I see some stuttering. My monitor is on its own TB2 bus and the vid files are on a fast external TB2 SSD . I've tried two different 4K DP->MDP cables (4K certified) .
I've used both VLC and QuickTime and see the stuttering with both, but worse with VLC. Is this a TB2 bus issue ? Prores 422 files are best, but still show the problem. I know it's not in the source files because it doesn't always occur at the same frames.
I'm not sure what to expect ?
