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?
OLED is a massive upgrade. Each pixel is its own backlight instead of having an array of leds. So you get actual black, because there is no light there. The contrast and color is amazing.
But OLED is the new plasma. They don’t have burn in anymore, but if you don’t have it in a very dark room, the glare will make you go insane.
