well what's the budget for a t.v. as OLEDS will look a hell of alot better than LED sets even though LED'S look great to but OLED sets are just breath taking in 4k. yes you'll need an hdmi with 2.2 i forget what it is now and you will also need a set with atleast HDR 10 built in it also. i would borrow a friends set just to get it hooked up and rolling how will they know your only borrowing the set. i don't know if the dtv boxes will have handshake issues with the t.v. as well but that's a firmware update to. what do you mean as far as cheap t.v.s brands like hisence and tcl??? i have an OLED sony that i spent an eye watering price for 10k but it's worth every penny to as it has an awsome processer to upconvert!!! and how big of a set are you looking to buy anything under 55 inches is just a marketing ploy.
