What Is the Difference Between an HD, Ultra HD and 4K TV?


If you are thinking about changing your TV for a "better image", consider this information when choosing it.

 
By simple logic it may seem simple to say that the difference between these TVs is that one has a better image than another. This is true in some way, but also each of these types of formats have certain characteristics that are worth knowing.
 
Currently there are several high quality video formats. The high definition formats and the extra large screen TVs have led to a new generation of video formats, that's why we have gone from hd to full hd and 4k.
 
First you need to know what the pixels are. The pixels are the number of colored squares that the television has. The more pictures, the better the image. These pixels are counted as vertical and horizontal, that is, the number of vertical color boxes and the horizontal amount a television has.
 

What is HD?

Its acronym in English means 'High Definition', which means 'High Definition'. This is a video format that offers higher resolution images per screen, than the standard video format. This format has 1280 × 720 pixels or 1920 × 1080 pixels, which represents a breakthrough compared to the 720 × 576 pixels of the standard video resolution. This size allows us to see images with a high level of detail and quality.
 

Ultra HD and 4K

With the arrival of larger screens, there was an evolution in the video format. This led to consider the HD format as obsolete, since its number of pixels were not enough to display on larger screens. So it can be said that the main difference between HD and Ultra HD and 4K formats is that the latter have better quality and quantity of pixels.
 
Ultra HD has a resolution of 3840 × 2160 pixels and a color of 10 bits. While 4K has 4096 × 2160 pixels and a color depth of 12 bits.
 
Another difference between the Ultra HD and the 4K, is that the Ultra HD maintains the current format of 16: 9 TV, allowing to take advantage of the full size of the screen. While the 4K, requires a complete change of the format, so there is still not much content made in 4K and is beginning the transition to this format.
