BLACK FRIDAY 4K TV BUYING GUIDE
4k is an up-and-coming video technology that gives you a better-quality picture when you are watching movies or TV shows. The term 4k refers to the resolution of an electronic display. A display could be the screen on your TV, your iPad or your laptop. Resolution means how many pixels there are in that display. Pixels are the dots that make up on screen images, and the more pixels there are the sharper and more realistic images look. When we can see individual pixels, images look blocky and less lifelike, so we usually prefer displays with a higher resolution. 4k also known as Ultra High Definition, is a very high resolution indeed. In terms of technical products, you can buy like TVs, 4k normally refers to a resolution that has 3840 pixels along the horizontal part of the display and 2160 pixels vertically. The name 4k comes from the fact that there are roughly 4,000 pixels on that horizontal side, which gives 4k approximately four times as high resolution as 1080p. This is what we normally mean today, when we describe something as full HD. Higher resolution does not necessarily mean a better viewing experience. You also have to factor in screen size and viewing distance because there is only so much detail a human eye can perceive at a given distance. You will get more from a 4k display the larger the screen is and the closer you are. So, if you want a regular-sized TV for your living room and your sofa is say 10 feet away from it, the extra detail you could get with 4k, might not be worth paying the extra for. To get the benefits of 4k, you also need whatever you are watching to have been sent to your TV in 4k quality. Netflix has made some of its shows available in 4k, but it will be sometime before most broadcast television is transmitted this way. Aside from your TV at home, 4k can take other forms, movies have been shown in a slightly different version of 4k in cinemas for some time. There are even phones that can record videos in a resolution high enough to qualify as 4k. But wherever you see the term, just remember that it is shorthand for the number of pixels that a product can display or record, and you will be able to make sense of 4k on your Black Friday TV.
