No need to use all the functions if you don't need them...
As soon you get above 32" screens the smart tv is all you can get though, and if you really get the latest new fangled telly it is all you can get.
With all the channels available here i don't use the gadgets on it much, sometimes a you tube video or a 4 K UHD thingy.
Quality on satellite is better as cable, i think they use higher compression, so most my watching is HD or UHD channels on satellite.
Just watched an UHD HDR trailer on Astra satellite, really impressive.
