Summary: Great TV in most respects but shockingly for the price none of the 3 HDMI ports support HDMI 1.4 ARC. This is not great for a new TV if you are planning on connecting an AV receiver for home cinema or surround sound. Nowhere does it say ARC is not supported except in the very fine print of the product spec on the Samsung website.
Summary: Ive had this tv about two weeks and I'd give this tv a 5 star except...the only audio out is optical cable. Basically, for me to hear anything from the tv say my Xbox games or anything from the smart hub (Netflix, YouTube, etc) you will only get sound from the tv speakers. They suck. It has a great picture and features. But my older receiver I was using for surround sound is now incompatible, I also had wired all my cables in the wall last year during a renovation.
