4K (or UHD) and HDR are both designed to enhance your viewing experience - however, the way each technology does it is very different. To reiterate, 4K refers to the pixel count in your TV screen, which enhances image definition and texture. HDR, on the other hand, refers to the color depth and quality of your image. While your next TV will likely be 4K because it is standard technology and comes with affordable prices nowadays, it is not guaranteed that it will also contain HDR technology. If you're shopping for a brand new TV, make sure it has both 4K and HDR features for superior image quality.nnSo, as you can see, it isn’t really a case of UHD vs HDR, but more a question of making them work together to produce the best viewing experience you, and your family can have.
