Call Samsung to do 2 things.
1. Have them check your firmware for latest.
2. Answer your question.
If you don't want to call 1800SAMSUNG (USA) then use the Chat feature at samsung.com
I have used both and get answers in about 2 minutes.
I just got a 2015 model 8 series Samsung smart tv and cannot seem to be able to view 4K video on Youtube. The operationg system does allow the small settings icon to show to allow the 4k setting or any other setting to be used for viewing. Is the Tizen operating system the blame for this or is Youtube? Shouldn't a high end 4K tv be able to view 4K tv from the internet. Should I connect my laptop to the tv with a HDMI cable and let the computer operation system process the video. Any suggestion on how to view 4K video with any source other than a player which I don't have?
Thanks, RIck
