Let’s take a closer look at what is Full HD, Ultra 4K HD. What is the difference between the two quality formats? And with what parameters it is better to choose televisions.
Full HD story
Resolution is a parameter of the image transmitted to the screen. It is measured in points, pixels. The higher the score, the better the quality and detail. Modern TVs support HD and Full HD resolution. The first format starts at 720 by 576 pixels.
Modern resolutions are being standardized. That is, they have exact parameters that manufacturers do not deviate from. So the HD resolution is 1280 by 720 pixels. Full HD revolutionized the standards in 2007 with 1920 x 1080 pixels.

In addition, there is an amorphous standard Full Sd with parameters of 1140 x 1080 points. The pixels are not square in this case. In regulatory documents, this version of the standard is called HDV.
Interesting fact. The first feature films on BluRay and HD DVD were released in HDV format.
Modern quality
The modern definition standard (SD) is 720 by 576 pixels. Old Full HD format: 1280x720p. And this type of detail refers to high definition. The updated version is 1920 x 1080 pixels. And at the same time, there are 2 subtypes of the new 1080 format: progressive, interlaced.
Full color 1080p progressive subtype features instant video output. In other words, the frames are not fed sequentially, which helps prevent the appearance of the comb effect and preserves the maximum detail of the image.
In addition to the good picture, the popularity of Full HD is due to the following factors:
Devices with matrices, whose resolution is compatible with 4K or 8K, cost several times more.
The 1080p picture parameters are sufficient for high details of small objects even on modest 110 screens.
Image clarity in 4K and above is not intended for home viewing. Until now, this format is used in full-scale cinemas. Not all televisions support this format.
Even when you watch cable and satellite TV, movies are broadcast in HD or Full HD quality, it is almost impossible to see the UHD parameter. Ultra-HD movies are only available in very expensive TV packages.
Advantages and disadvantages of 1080p quality

Large options. The image is located in an area of 1980 by 1080 pixels. These dimensions are enough to cover even the largest screen with an image.
The availability of equipment with this parameter. Even domestic manufacturers produce 1080p televisions. Foreign TVs Samsung, Sony, LG are equipped with the same modules.
A lot of content in this capacity. Advertising, television and Internet videos are supported in the full-size video format.
Full software compatibility with older CD versions. Even a simple video in HD 720px is perceived by modern technology as Full HD, in the H.264 video codec.
Despite all the advantages, modern quality has a drawback: too much information requires a very high speed of work. If something is playing from the Internet, the connection must be high speed.
