I know there's been a few threads on this but I don't care to look. I went to buy a tv yesterday and I knew what I wanted but I got all thrown off when I started looking at 4k. I have a 40' Samsung Smart TV 1080 120hz in my bedroom and was going to get the same thing in 50' for the living room. I can get a Vizio 50' Smart TV 4k 240hz for nearly the same price. I don't see any cons her except it's not a Samsung. The salesman made it seem like the 1080 will break in 5 years (lie) while the 4k will last 10+. 4k's can upgrade programming from 480-1080 to nearly 4k resolution as well, according to the salesman. But, when I got home the specs said that it did not have inputs for HDMI chords. Is this across all models? Everything I have is thru HDMI so I'd have to get direct tv to send new chords and then I'd have to buy new chords for my devices as well? Right now that's my only hangup and it looks to be a big one. Hopefully I'm mistaken.
