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?
