Some bring up the 30Hz HDMI issue, others note CNET 4K articles but I'll skip 4K for a time and get to the store but not let the sales show me the screens at me standing a foot away from the 4K screen. Even 720p Plasma rivals a current 4K screen. Read http://www.cnet.com/news/budget-tv-resolution-rumble-720p-plasma-vs-4k-led-lcd/
My thoughts? Don't over invest. Get a 2 year warranty. Read CNET 4K articles.
I don't know whether to buy a Samsung 55H7000 or the new series 55JU6800. I know the latter is 4k but being a 6 series are there other things that are worse? Maybe its normal 1080p quality?Samsung makes it difficult to compare them on their website. No motion rate number etc. They are the same price now as H7000 is end of line. Any help much appreciated, I don't really know anything about the topic. Thanks in advance.
