I recently bought a 4K 120Hz OLED TV for about $550 and was surprised by how inexpensive it was. A few years ago, I expected a 4K 120Hz display to cost at least $800, while OLED models often started around $1,500 or more. After looking around, I found that entry-level OLED TVs with these specifications now commonly sell for roughly $800, with occasional discounts bringing them much lower. My previous TV was a 4K 60Hz model purchased about three years ago, and it still looks good, but the price made upgrading seem worthwhile. What changed to make high-end TV technology so affordable?

Manufacturing has improved a lot. OLED production yields are better, factories have more capacity, and competition between several major brands has pushed prices down. TV technology also moves quickly, so last year's premium features become standard features in cheaper models. That said, a $500 TV and a $1,000-plus model can still differ noticeably in brightness, processing, motion handling, build quality, speakers, and long-term reliability.
Size and timing make a huge difference. Smaller OLEDs and heavily discounted models can fall into the $500–$800 range, while large premium sets are still extremely expensive. An 85-inch OLED, for example, can cost several thousand dollars. Retail sales, clearance events, and newer model releases also make previous-generation TVs look dramatically cheaper.
TVs have been getting cheaper for well over a decade because flat-panel production became mass-market and older display technologies were phased out. The tradeoff is that many modern sets are designed more like inexpensive electronics than repairable appliances: a failed panel or control board can cost nearly as much as replacing the whole TV. So the purchase price is lower, but lifespan and repairability are worth considering.
The low prices are partly balanced by advertising and data collection. Smart-TV manufacturers can earn money after the sale through advertisements and viewing analytics, which lets them sell the hardware at relatively thin margins. If privacy matters, you can avoid connecting the television to the internet and use an external streaming device, although that device may have its own tracking policies.
