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?
If your budget allows, buy an OLED.
If not, don’t look at one in person or you will feel sad.
Edit: clarification
Terrible advice. If budget is a concern, then a TV with organic decay really isn’t what they should be looking at. That and with newer technologies like micro-LED, OLED is no longer the be all, end all it once was, especially when longevity isn’t a problem for these other technologies like with OLED.
