Since it's unfamiliar to many people, it's also the source of the vast majority of the confusion about TV resolution. The most common resolution for new TVs is 4K. That said, it's still worth understanding the various resolutions used by TV makers and others. A TV with better high dynamic range (HDR) performance, a better overall contrast ratio or better color will look better than one that just has more pixels. It might, but not always, and for reasons that have little to do with resolution. Just because a TV has higher resolution than another, doesn't always mean it's looks better. However, resolution is not the most important ingredient in picture quality. Resolution is one of the most common specifications used to sell TVs, partly because '4K' and '8K' sound really high-tech and impressive. You'll have to look very closely, or whip out a magnifying glass, to discern each one. And the newest, largest and most ridiculously expensive TVs have over 33 million pixels ( 8K). Even newer and bigger TVs (typically 50 inches and above, although numerous smaller sizes too) have 8 million (for 4K Ultra HD). More recent and slightly larger TVs (typically 49 inches and smaller) have a little over 2 million pixels (1080p). Older TVs, and many 32-inch models sold today, have a million or so pixels (720p). There are numerous resolutions found on flat-panel TVs. A single pixel, or discrete picture element, consists of a tiny dot on the screen. Resolution, in terms of TV hardware, refers to the number of pixels that compose the picture on the TV.
