You shoud know that this Samsung models comes with a 100mb nic. So, I have to connect the TV via WIFI AC technology.
It works fine with 1080 BR remuxes and 4K rips but with ‘fat’ 4K remuxes(70-80Gb weight and 80-85mb of average birtrate) I’am experimenting stuttering and lag on direct play scenarios.
WIFI AC should manage without problems 300-400mb(the Tv is near to the router and PMS has 1000mb wired connection to the router.
