I recently bought a 65 inch Samsung 4k HDR tv. Now my dvr stutters on that tv but works normally on the others. On the one that stutters, I am running 4K ATV using the latest beta. On the other tv, a 43inch Samsung 4K HDR is using a non 4k ATV also running the latest beta. I am using a Synology 218+. Everything worked great on my eight year old Samsung HDtv. I change the transcoding to software from hardware and it seemed to improve it. I noticed it stutters when I just try watch OTA real time also.
Any ideas?
