What is 4K? Learn all about 4K UHD and what it means for the future of television. The term "4K" refers to the increase in pixels, or display resolution. 4K means that displays are around 4,000 pixels wide, or 4 times as many pixels as a 1080p TV. 4K video content must be captured with special cameras to match the resolution of 4K TVs. If you have a 4K TV, don't worry; you can still enjoy content that isn't in ultra HD resolution. In fact, many 4K televisions have an "upscaling" feature that enhances content as close to 4K quality as possible. Images are clearer and crisper for an enhanced viewing experience. Many streaming services like Netflix have 4K shows as well. The great thing about enjoying 4K TV is that you don't have to purchase any additional equipment to enjoy; just plug in your television and get started.
