The only way you can see 4k content on the Sony is through your pc.
you have to connect an HDMI from your card to the sony.
The content you can get from you tube
Your timing is really bad because there is a program called 4k downloader which we use to download the content with, and a few days ago, you tube changed their algorithms, so 4k downloader no longer works at downloading 4k content. The developers of the software are trying to fix this.
If you pm me, I will give you an alternate program which requires username and password. It works really well.
Unfortunately there is no other way of watching 4k content on this tv. In the Samsung forum, they have figured out a way to crop a 4k video into 4 quadrants, and to paste this onto the samsung via USB.
This does not work on the Sony.
Basically the sony has a good picture...nothing else.
Yes I did do my due diligence and bought it because of the PQ and Passive 3d.
It does nothing else, meaning that 4k content in hard to watch compared to the Samsung and especially the Panasonic, which both accept 4k content via USB.
