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?
Dark scenes look a lot better and more detailed. The rest not that much.
You can’t fully experience season 8 of Game Of Thrones on an LCD TV. But then again it’s not really worth experiencing.
Gradation, color reproduction, and gaming performance are also important factors. There are a lot of “mid tier” TVs (and even some of the “premium” TVs) that can produce really dark blacks, bright whites, and vivid colors, but…
Gradation: Mid tier and above non-OLED TVs have local dimming and other features to improve blacks and contrast. They tend to have dark blacks and very bright whites, but their performance in between is important too. You will find that many of these tvs are hard to impossible to calibrate to get even gradation between black and white. This leads to muddy grays and “crushed” blacks and whites. Crushed blacks means that very dark gray appears black so you lose detail. Crushed whites means the same on the white end. Additionally, local dimming can lead to “halo” effects in which when there is a quick transition from black to lighter colors, the black area has a halo around it.
Color: In my experience, the colors are often off. Youll get really vivid colors in certain tones and more muted colors in others. This can lead to a picture seeming to have a tint to it. Skin tones, which we tend to be more sensitive to, may appear greenish. These TVs will often have a “feature” to improve skin tones because manufacturers know that people notice that. This feature will try to correct green (or other tint) but tends to also influence reproduction of other colors.
Gaming: many TVs have a “game mode” which reduces input lag to make gaming better. Input lag is the amount of time it takes for a video signal coming into the tv to be displayed on the screen. With gaming mode off, many TVs have input lag that is 70-100ms (100ms is 1/10 of a second). This amount of lag is very noticeable in any game that requires fast reactions. Gaming mode input lag tends to be great these days - often 10ms or less… but on a lot of TVs it comes with a big price: many of the TVs picture processing features get turned off. This can include local dimming, which means you end up with gray blacks and a muddy picture in gaming mode.
I purchased and returned three higher end tvs ($900 to $1200 for a 65” tv) from about 2019 to 2021 in an attempt to replace a 55” plasma TV from 2013. Despite the fact that the plasma was 1080p and had no HDR capability, the picture was way better than any LCD-based variety I looked at (note: LED, QLED, and MicroLED are all LCD tech). All of them were bad enough in one or more of the above areas for me to return them. Most notably, I game on tv and that is where the failures of these TVs really really showed. Finally, about two years ago, I dropped the $$ for an OLED (LG C2). This was a true upgrade and I am really happy with the picture and performance. Not to say there aren’t software issues, but it felt like a real upgrade.
