Cheap flat screens tv7/25/2023 Reading the fine print when purchasing your new LED TV is important. Keep in mind that brightness can influence your TV's longevity - check out why you should adjust your TV’s brightness. Newer models today have more than 1,500 nits in brightness. As for TVs, anything within 100 to 400 nits is considered low luminance. Like most electronics, it is measured in nits which is equal to one candela – the approximate amount of light from one candle. Many TV manufacturers are prioritizing HDR on premium LED TVs with 4K quality than 1080p or 720p so there’s no need to choose between the two.īrightness is a measurement of your TV’s maximum luminance. 4K simply refers to the resolution of the image while HDR is more of a feature. Contrary to what most people think, HDR and 4K are not competing standards. It is the contrast or color range between the lightest and darkest tones in an image. HDR (high dynamic range) is your TV’s ability to electronically enhance image quality. If you try to produce the same image on a modern 16:9 HD screen, it will appear stretched on the top and side or have black spaces. For example, old CRT TVs are square and therefore have a 4:3 aspect ratio. Along with that is the screen’s aspect ratio which is the relationship between the height and width of your TV - in other words, how the image is oriented. Resolution defines the clarity of an image based on the number of pixels on both length and width dimensions. If you don’t want to do the math, here is a quick guide on TV size and viewing distance: If you sit too far away from an exceedingly small screen, you would not be able to see enough detail in the picture. This is important because if you sit too close to a disproportionately large TV, you can easily spot individual pixels which ruin the experience. According to the audio-visual authority THX, the optimal distance from your sofa (or wherever you may be viewing) is dividing the screen size by 0.84. It is easy to assume that “bigger is always better” when it comes to choosing TV sizes. When buying a brand-new LED TV, you should look at the size and viewing distance, its aspect ratio and resolution, and other features.Īs a standard for measuring TVs and monitors, screen size is measured diagonally from one corner to the other. There’s much more to consider than the arrangement of your diodes. This type of backlighting arrangement is often found on mid- to low-range TVs. This means individual LEDs cannot be controlled individually when showing dark scenes, unlike the full array.
