Another thing my advise is dont buy 4K TVs now .Now presently in market 4K TVs are 1st generation TVs as they are having 1.4 HDMI option and for proper 4K viewing we have to be 2.0 HDMI enable option which is not available in market.So be patience and once these 2.0 HDMI enabled TVs will come in to market that time only buy these products and I think it may take at least 1 more year.
