I may be missing something here, but... I've just bought a 4K OLED "Smart" TV, however I can't stream anything in 4k. I have the network speed to support it, but the wifi is too unstable (but fast enough) and the ethernet is too slow. Analiti shows that on Wifi I get about 160mbps and on Ethernet only about 20 (it's a gigabit switch with cat6 cable)
It's all NIC/speed related; no errors. When I force 4K (YouTube) it will play, but it will spend more time buffering than playing. I can stream the same 4K content on my PC (connected to the same gigabit switch) no problem with no buffering. I can also stream the same 4K content on my PC via the same wifi network with no buffering issues.
I have a kd75 xf9005 and I can watch online streaming 4k from netflix and amazon fine. However if I try and watch videos via my home network they judder and sometimes stop altogether. It only happens with large 45-60gb 4k 24fps (40-60 Mbps) movies. I have tried wired and wireless 5g, neither work very well. 5g is slightly better.
Hi,
The same problem. I have KD-55AG9 TV, conectly directly with Gigabit Ethernet, but the maximun speed of this port is fast Ethernet (100 Mbps). The result is that I try to view any 4K content from my NAS and the movies are "keeps buffering" and "jumping".
I try to use any APK like VLC, MX Player, etc... and Nothing.
Netflix, Amazon, HBO and Other APKs play perfect, but the streaming from my NAS when I use 4K "Big Files" (40Gbytes or more) are Horrible.
The only solution (Worst Solution) is use 1080p Movies (With low frame rate - 5 Gbytes of size) in these cases the movies playing perfect with whatever APK (VLC, MX..)
It's a shame that one spensive TV have and FastEthernet port instead of GbE Port..and is a shame like I need to use and external Chinese android appliance connect via HDMI to my TV for watch 4K Remux content from my home network .
