When you go to a store looking to buy a device with a display, such as a phone or a TV, you are faced with a number of confusing terms.

You’d better get in touch with them, first of all praise the right decision.

One of the main characteristics is the separate size of the screen that you need.

We would like to explain to you the difference between standard terms and the permissions that they imply, and don’t forget The sharpness of your display, pixels per inch, depends on the size and size screen.

In other words, a 2560 x 1440 pixel display looks sharp on a smartphone, but it doesn’t look as sharp when stretched across 40 or 50 inches of space.

Just remember that more pixels does not always mean a sharper screen, so dimensions are also important.

HD І VERY HD

To begin with, HD is High Definition.

This term was first used in televisions and meant the presence of 720 rows and, above all, the primary combination of resolution - 1280 x 720 pixels.

Full HD has raised the number of rows to 1080 and the typical size has become 1,920 x 1080 pixels.

4K initially appeared as a cinema standard with 4096 by 1160 pixels, hence the name 4K.

However, the live electronics have changed to 3840 x 2160 pixels.

So the reality is 4,000 is missing.

However, in 4K you will have to go with Full HD.

UND or Ultra High Definition means 4K – 3840 by 2160 pixels.

These terms are the same, but most of them are used for 4K gaming devices and TVs.

What does the next day have in store for us?

These are the main terms you will find in your online search for the devices you need.

Ale є inshi.

The video frames move forward 5K (5120 x 2880 pixels) and 8K (7680 x 4320 pixels).

It is important to say that if you look at the massive screens, the human eye can clearly see the difference.

The reason is simple - there is a dry number and the ability to say: “The more, the better.”

Just explain it clearly, otherwise you won’t be able to get it right.

So, it’s more common to talk about cameras about the resolution of their matrix (“megapixels”), and not about any other parameters.

For this reason, many journalists respect the fact that the higher the “megapixel”, the better the camera.

Tim in an hour.

Likewise, most displays have a broadened estimate of pixel power, which does not reflect all aspects of screen brightness.

This explanation is the easiest to understand and for this reason the most popular.

Testing for real

Pixel density and screen separation are not the only factors that influence image vibrancy

For those who are using their current phone with a screen of approximately 5 inches, the buyer will most likely need an HD screen with a separate 1280 x 720 pixels and will want to upgrade to other characteristics The device has a processor and RAM.

If the company Sharp i, great tabletops can be made available.

For many people who don’t know the exact characteristics of the device, can they immediately get a 5-inch smartphone screen (HD or FullHD)?

Over the past few years, the evolution of screens has reached such progress that few people can enjoy a clear picture on Full HD in 1920x1080 pixels at a frequency of 120 Hz.

I would wonder what more would be needed to be satisfied with the look?

Ale Full HD is no longer the limit.

Models with 4K and Ulta HD are already being sold on the market separately. 4K is a designation for separate production in digital cinematography and computer graphics, which is approximately 4000 pixels horizontally. There is little respect for the goodness of Frequency, which is due to the presence of screens of various separate parts. What does that give? This (roughly apparent and explained in simple terms) fluidity of the thickness of your screen is associated with this blurring between the image frames.

The lower the frequency, the more strongly the change in frames is perceived: the stench becomes “ragged”. However, more importantly, there is less pause between frames, the image becomes smoother and is captured better. Difference between HD, UHD, 4K and 8K High-definition TV (HDTV) is a standard that has been in use for the past decade. Now it is important to go to the store and buy a TV, which is not the least HD Ready, Which means “building displays separate buildings at 1280 x 720 pixels (720p).” There are absolutely more current TVs that you can buy, and Full HD

, Which means “building display with separate building 1920 x 1080 pixels (1080p)”. Litera " adapt to any display format with horizontal separation of approximately 4000 pixels.

Whole little bits are beaten from the pantelik, since at lower resolutions the format is written to the values ​​​​of the number of pixels vertically, then. 1080i chi 720p. UHD or else Ultra HD- The same ones 4K, with one caveat: the TV station is more suitable for people living, and also has less space 3840×2160 pixels ( Ultra HD.

• (), nizh In this manner:
• DCI) Digital Cinema Initiatives standard is a professional production standard, which is the most expansive for digital production for separate production 4096 x 2160 pixels. UHD-1, often called Litera " 4K UHD or just, and sometimes

2160p DCI, which has become standard for televisions that have separate units of 3840 x 2160 pixels, which is much higher than the number of pixels in the Full HD format. Most current TVs not vikorystvo wider than the spіvvіdіstvenniya parties

DCI 4K , since most television content is suitable. The format is the same Full HD Ultra, sometimes they call it . 8K

, there is a separate building 7620 x 4320 pixels

There are a number of TVs on Yandex Market that can boast such a screen resolution and a perfect picture, but it is recommended to choose a Full HD Ultra TV with a diagonal of at least 85 inches.

On a smaller diagonal, you simply won’t capture all the richness of the picture, which is possible at 8K.
Ultra High Definition, or UHD for the full HD stage, the official name of the display with a separate size of 1920 x 1080. UHD has a larger size of up to 3840 x 2160. about 4K, the fragments of separate production 4K are higher, but they are not Most of the time, a TV or monitor with a separate UHD component is advertised as 4K.

Of course, there are separate panels with a resolution of 4096 x 2160 and a ratio of 1.9:1, but what is important is the larger size of 3840 x 2160 with a ratio of 1.78:1.
Why not 2160p?

It’s amazing that videographers know the difference between 4K and UHD.

Ale, perhaps, due to marketing mongering, the term 4K will be adjusted.

Anyway, so as not to conflict with this DCI standard, they often use the phrase 4K UHD, wanting to write simply 4K.

What is even more confusing is that UHD is actually divided into two parts – 3840 x 2160 and then significantly increased to 7680 x 4320, which is also called UHD.

To differentiate them, the terms 4K UHD and 8K are used differently, or, to be more precise, 8K UHD may be renamed to QUHD (Quad Ultra HD).

Real decisions would be made in the name of 4K and the price of 2160 rubles.

Also, the screen size is no less than a meter diagonally.

To look at the clarity of an image the size of a car, it is important to view it through a screen the size of a knee.

If you have horizontal shadows, this means that the original video format is simply not suitable for your viewing device :)

Hint: You need to start the video and open it to the next screen.

• For people who actively use their cars, it is important to have a video recorder in the car. This device allows you to bring your dishonesty to the road and transport benefit in court and, as a result, protect a large amount of fines and consequential charges, or, in particularly important cases, preserve freedom. However, without any adjustments, video recorders can guarantee better results.

The picture must be clear enough so that everything depicted on it can be viewed in detail, and for this it is necessary that the video recorder be taken from a good separate source. What kind of video recorder is practical to use as a vikorist? It allows a large number of people to take cheap video recorders from which they get maximum support

  Full HD is the most popular format. This is supported by 99% of devices, including inexpensive video recorders for cars. 1920 Full HD – not allowed x 1080

, and it is significantly (approximately twice) clearer than HD.

In the video above, other details are clearly visible. On still frames, you can see, for example, not only the license plates of cars that are ahead of you at a distance of up to 10 meters, but also those of cars that are passing from the side. Porivnyano from What does that give? HD , video in

• takes up approximately twice as much space on the memory card.
  For example, a movie in 720p is about 200 megabytes, while 1080p is about 300-450 megabytes. The specific size depends largely on the format, compression level and video bitrate., і Super HD and Quad HD. More expensive registrars support formats Quad HD Super HD

• It is practically impossible to look at them directly, so they are allowed to contain similar things:
  Quad HD – 2560 x 1440 pixels, and Super HD – 2304 x 1296 pixels

- It's lower.

A picture shot in one of these formats is clearer than Full HD.

You can look at other or more distant objects at the price.

A video in this format takes up about 500 megabytes.
4K (Ultra HD) is the clearest video format available.
This is a completely new format in car video recorders, which is increasingly gaining popularity.
Ultra HD (or, as it is also called, 4K), takes 3840 x 2160 pixels separately, and is also approximately 4-5 times clearer, lower than FullHD.
The downloaded file takes up over 500 megabytes of memory.
Ultra HD is the best solution for the car enthusiast, and even from such a separate view you can see all the details (license plates, road markings, signs, inscriptions) on large roads.

Other important characteristics of the video recorder.

By the way, when choosing a video recorder, you must take into account some of the most important characteristics: matrix, processor, memory card format, light sensitivity.

Popular in our region, color TV systems SECAM and PAL, which are widely used in broadcast and cable broadcasting, transmit 625 rows and 50 frames per second per row.

Through unpaired and paired rows.

As a result, the visible image is formed at 25 new frames per second.
Alternately displaying a frame on the screen allows for a reduction in the frequency range of the video signal, which is especially important for RF modulation in a terrestrial analogue television station, since this method is widely popular in terrestrial and satellite television broadcasting systems. gram. Through the reversible process when forming frames and rows on televisions with a cathode tube, some of the rows are not involved in image transmission, but are instead used to transmit technical information - color synchronization and transmitting data in teletext mode. In LCD and plasma TVs, the display of such a video signal in the popular PAL or SECAM systems, when scaled by a graphics controller, implements the layout standard HD Ready 526i

In which to form a visible image, 526 rows are used (with 625 existing ones). Index.

shows that the rosette is interlaced.

The NTSC video signal transmits 525 rows and 30 frames in 60 frames.
Implemented in graphic format by standard layout

High definition HDTV However, more importantly, there is less pause between frames, the image becomes smoother and is captured better. With the growing popularity of computers and TV sets, there has been a need for image shaping at a higher rate, which has led to the expansion of the progressive (ordinary) method of frame shaping in TV sets. HD Ready This is how the standards for laying out the video signal for the higher resolutions of HDTV emerged.
The recording standard must specify the number of visible rows and the method of shaping the frame. Index- progressive indicates a progressive rosette with row images of the frame, or

- interlaced indicates an inter-row arrangement.
For example, standard layout
720p Index Can be implemented on TVs with separate screens 1280x720 or 1366x768 for a 16:9 frame format and with separate screens 1024x768 for a 4:3 format.

The 48 rows that are missing are not affected by the molded image and can be used for the transmission of technical information or extinguishing during the turnaround time in TVs with a kinescope. For separate production 1920x1080 frame format 16:9 there are layout standardsі 1080i 1080p
Suitable for alternate (i) and progressive (p) cultivation. For separate production 1920x1080 frame format 16:9 there are layout standards Unfolding
720p 1080i It is difficult at this time when broadcasting many satellite channels that transmit HDTV, but the width of the range of frequencies during modulation is relevant.

Can be implemented by formulated and transmitted video signals by computers, video cameras or Blue-Ray DVD players.
Let's talk about the development of EDTV (Enhanced Definition) standards, which became a transitional stage from the standard SDTV broadcaster to the high-definition HDTV broadcaster. In the USA, EDTV has been adopted by the Consumer Electronics Association CEA to establish digital display standards 576p (PAL) that 480p
(NTSC) from a frozen progressive flare. In the USA, EDTV has been adopted by the Consumer Electronics Association CEA to establish digital display standards In EDTV standards, the frame frequency is still 25 Hz for (PAL) that.
ta 30 Hz for Index.

In Russia, EDTV is known under the term “Advanced Clarity Television”.

Compliant with GOST R 53536-2009, it is subject to the transmission of signals from a row-folding frame and the number of visible rows in a frame is 720. Complies with the standard-folding

When broadcasting a signal in digital format DVB-T, DVB-T2 or cable DVB-C, frequency modulation is not vicorized, and frames are transmitted using MPEG standards, so the concept of the range of frequencies and the layout of video is no longer relevant. What does that give? 1080i chi 720p. Full HD chi HD ready? You can often see logos on TVs
HD ready

Also, these inscriptions may be present in the technical specifications and on the price lists of TV sets.

Full HD chi HD ready? What does the stink mean? Indexі For separate production 1920x1080 frame format 16:9 there are layout standards.
A lot of controversial and questionable results from this drive can be found on the Internet.
HD ready is a European standard that regulates the technical feasibility of implementing HDTV on a TV. 1080i- provides support for folding standards

This means that the TB can accurately (pixel-to-pixel) display the signal in a separate area 1280x720 with a frequency of 50 or 60 Hz and a progressive pitch, as well as in a separate area 1920x1 080 with a frequency of 50 or 60 Hz, or even with an alternating frequency.- indicates that the TV is designed to support, in addition to the described HD ready modes, a progressive display in a separate format of 1920x1080.

For this option, the term Full HD was introduced, which means a new set of all HD modes.
In these and other options, Full HD logos can be displayed at the maximum capacity of HDTV, for example: Full HD 1080p Index, For separate production 1920x1080 frame format 16:9 there are layout standardsі 1080i- advertises that the TV is designed to support all HD standards, and itself:
for all possible TV resolutions and with any frame rate.

For more information on the modes supported by the TV, please refer to its technical specifications.

UHDTV High Definition TV Tower or just Serpnya 2012 adopted two more sets of 4K UHD TV digital television standards ta 8K UHDTV.
4320p or just We have already appeared for sale of TVs and standard layouts

with separate building 3840x2160. ta 8K UHDTV To implement the standard
There are currently no demonstrations, for example, presented by the Japanese company NHK, which has expanded the Super Hi-Vision format with the support of resolutions for 8K UHDTV.

One year of compressed video in this format takes up about 25 terabytes.
