I feel like it used to be size, color, and clarity meant more expensive. Now I look at a 500$ 4k TV and a 2000$ 4k TV and I don’t know what the difference is. They can both be smart TVs, be the same size, and have a lot of same advertised features, but what are the subtle unspoken mysteries that justify a huge price gap?
One thing about 4K and 8K is there’s not a lot of media available for that format.
Most streaming media is going to come in at 720p or maybe 1080p unless you are comfortable with paying top dollar for your streaming.
