The tv looked amazing in 4k on actual 4k content. its 4k upscaler was nice too..over all it would have been a god tv if it was for mine having a cloudy spot lower left about a 4 inch bubble too.
i ended up going with an lg 4k from walfart and its AMAZING, im shur this site carries some lg 4k's..
sorry samsung you lost a loyal customer i now will only buy lg tv's..
