![]() Fortunately, most people should have several options for recycling their old TV.Įach state and county has different guidelines for recycling, so you should start by Googling your city’s television recycling options. A TV needs to be processed at a facility that’s equipped to disassemble it. Our picks tend to excel at these tests, but they also need to be priced reasonably and not introduce any hardware, compatibility, or user-experience issues once they’re in your home.Ī TV can be recycled into a number of components, including copper wiring, plastic, and glass, so you should never just throw it in a trash dumpster. These measurements aren’t the sole indicator of a good TV, and they are not the only thing we take into account when recommending TVs, but they make up a healthy portion of what we test. Is its production of white light too red- or blue-tinted? Does it produce enough color for HDR content? Is it clipping off details on either end of the light spectrum? With one scan, we can get a good estimate of how a TV’s picture quality compares to the scientific standards. We use Portrait Displays’ Calman software a program specifically designated for display measurement and calibration, to tabulate those measurements into easily readable charts and tables. When we measure TVs, we use a device called a signal generator to send test patterns to the screen, plus a meter (usually a tristimulus colorimeter) to measure the light and colors that the TV produces. Major deviations from any of these targets can ruin a TV’s image and obscure details. 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.
