Modern TVs should produce a white point that’s exactly 6500 K, roughly the flavor of unclouded daylight. A specific color temperature, designated in Kelvin, dictates how grayscale elements should look. There are also targets for the hue, saturation, and brightness of a TV’s primary colors (red, green, and blue) and secondary colors (cyan, magenta, and yellow), depending on whether the SDR or HDR color spaces are being used for what you’re watching. For example, we have behavioral targets for functions called gamma (for SDR video) and electro-optical transfer function (or EOTF, for HDR video), which specify how much light a TV should produce across a range of electrical stimulus levels. But what does it mean to have “scientific” standards for TVs? Essentially, it boils down to light and color production, two stimuli that can be easily measured.įor both SDR (standard dynamic range) and HDR (high dynamic range) content, there are designated light and color targets that a TV should hit. Scientific standards for HDTV performance have been in place since 1990, and scientific standards for UHD TV performance have been in place since 2015. Knowing some of these basic points before you start shopping around can simplify the process and narrow down your viable options. If you’re buying for a bedroom, you probably don’t need a huge screen.Īnd if your intended room is especially bright, you may want to spring for a premium LCD TV since such models get a lot brighter than budget LCD TVs or OLED TVs. If you’re not planning on playing video games or watching Blu-ray discs, you probably don’t need a TV with a 120 Hz refresh rate, which tends to raise the price.
