Ultra HD TV is a more brilliant, more pixelated incarnation of a HD TV.
HD TV has vertical columns and 1080 horizontal rows of pixels, where Ultra HD has 3840 pixels by 2160 which is just a slightly smaller resolution than you would see at a cinema.
It has a sharper and far more detailed picture, as well as a lot more storage space and bandwidth.
Ultra HD is better than normal HD in the way that HD was better than standard definition in that it is easier to look at
Essentially more pixels means more information for the pixels which translates to a sharper image. This in turn makes the picture more “watchable”, more engaging.
Ultra HD doesn’t just support better resolution, it also captures faster frames which in turn can blend dynamics and colours at a quicker rate increasing the continuity and detailed visual presentation of what you are watching.
4K TV represents four times the resolution of ordinary HD displays. The clarity is second to none.Full HD TV consists of 1920 x 1080 which translates as 1080p, Ultra HD has 2160 x 1080 resolution. 4K screens have 3840 x 2160 or 2160p, around 8 million pixels which is four times what a 1080p screen can display.
It is called 4K simply because the image is about pixels are 4,000 wide.
The simple premise of 4K is that it has four times the resolution of HD TV, 8 million pixels. Obviously TV shows are going to be sharper and colour popping and interesting to watch but how does this affect any other aspect of our lifestyle?
For example, your photographs are taken in a higher resolution than we see on screen. When you put your digital images on loop, you are only seeing effectively a fraction of the shot. Try putting your holiday snaps on a 4K TV, it will be like seeing them for the first time.
This will depend on what you are watching. Not all streaming services are 4K ready so make sure you check before you download if this is the case. Once you have made your decision, it is probably advisable you check the broadband requirements and adjust your plan accordingly.
