Im wondering what kind of tv to look for?
IMO 4k is useless because the network where I live is bad and 1080p is good enough. I don’t think smart tv functionality is a thing to look for, more like a « what not to look for » criteria.
What other criterions should be taken?
I’m just assuming the OP is looking for a general advise on a new TV. If he’s actually looking for a 20 inch TV he is looking for such a niche device that he should probably have stated that.
But OP stated no real requirements at all which makes it nearly impossible to actually recommend something. What even is the TV used for? He wants a non-smart TV but but seems to be streaming? What about size? How is the room lit?
