Especially effective on large screens, 4K TV is also known as Ultra HD or UHD. 4K images are much more life-like because they have additional resolution and more color depth. Images should are best viewed on 65-inch or larger TV sets. While upgrading or designing your AV system, it's worth considering the added benefits of including TVs capable of rendering 4K images.
The higher pixel density of a 4K panel also enable you get much closer without the pixels of the image becoming visible – this means you can comfortably watch a much larger screen from the same seating position as your current Full HD panel.
