Full nd resolution. Difference between Full HD and HD Name of the Game: Ultra HD in action

Every TV or set-top box you buy today will support high definition (HD) video. Even so, there are tons of terms. Specifically, do you need to know the difference between HD Ready, Full HD, Ultra HD and Full Ultra HD?

In most basic terms, HD Ready TVs and set-top boxes can display 720p images with a resolution of 1280 × 720 pixels. Full HD TVs and set-top boxes display 1080p images with a resolution of 1920 × 1080 pixels. Ultra HD, or "Full Ultra HD", can go up to 4320p video with a resolution of 7620 x 4320 pixels.

The higher the resolution, the clearer the images appear.

But if it were that easy ...

HD Ready vs HD Ready vs Full HD

Wait, why is HD Ready written twice? Depending on where you live, the definition of HD Ready is slightly different. In particular, the US and Europe define it differently.

IN THE USA HD Ready for TV means the TV can output 720p images and has a built-in digital tuner. However, the same HD Ready logo is also printed on multiple projectors, computer monitors, and other devices that do not have a tuner. Television is an exception.

In Europe the digital tuner doesn't matter to get the HD Ready logo. The output signal must be 720p to get the HD Ready logo. On some older TVs, you may see the HD Ready 1080p logo. This is the same as the Full HD logo.

Worldwide Full HD 1080p gold logo is a standard which means 1080p images can be displayed on the display.

720 vs 1080

Logo aside, you need to know the actual quality difference. Your TV displays video as a series of lines, both horizontal and vertical. How many horizontal lines can your TV display at one time? This is the magic number: 720 or 1080.

With more lines, you get more pixels and therefore better video quality. That's why 4K and Ultra HD are even sharper.

Why is myHDReady 720pTVShow is labeled 1080i? (Progressive and Interlaced)

Things get confusing when you look at HD Ready 720p TV specs. There is another line that says it displays "1080i" videos. But 1080i doesn't mean Full HD. In fact, the salesperson might try to use this as one of their tricks to trick you, but don't fall for it.

“P” and “i” denote progressive and interlaced, respectively. Progressive and interlaced are how the TV displays each frame of video. As you know, most videos show around 25 frames per second.

In progressive scan or 1080p, the TV shows all 1080 horizontal lines at the same time.

In interlaced or 1080i scanning, the TV displays half the lines of one frame followed by half the lines of the next frame. The idea is to trick the eye into believing it is one image, but the human eye eventually sees a lack of quality.

Ignore "1080i" or anything with an "i" after it. Interlaced video doesn't look good.

Where will you see these logos?

While you will always see HD Ready or Full HD logos on TVs, they do appear on some other similar devices such as projectors and monitors. The most important thing for your TV is the set-top box.

The basic rule of thumb is that the video is played at the lowest speed supported by the device. In other words, if your TV is Full HD 1080p, but your TV box is HD Ready 720p, your TV will display a 720p picture. Some TVs will try to scale the video, but this does not result in a better picture.

Likewise, a 720p TV with a 1080p video jack (via your set-top box or game console) will only show 720p video. Thus, video of high quality will be available only when the input matches the resolution of the output signal.

Don't worry about "HD Ready" in TVs and other displays

Today, there is no point in worrying about the "HD Ready" tag on most devices. 720p has become the minimum default for every display device. So if you buy a TV, monitor, projector or something like that, it will support at least 720p video.

The Full HD tag can help you determine if it supports 1080p video or not.

HD Ready vs Full HD vs 4K vs Ultra HD

In the past few years, as technology has evolved, you now need to consider two other logos. Ultra HD logo and 4K logo.

4K is a subset of Ultra HD and refers to 2160p video at 4096 x 2160 pixels.

Ultra HD, or "Full Ultra HD", can go up to 4320p video with a resolution of 7620 x 4320 pixels.

Full Ultra HD is not currently available on most TVs.

Again, this isn't just about TVs. Even to play videos at the same resolution, you need an Ultra HD Blu-ray player.

Resolution versus quality

Unfortunately, marketers have turned image resolution into a measure of image quality. But this is not at all the case. There are several factors that determine how a video looks on your TV, and you shouldn't buy anything based on resolution alone.

The TV panel, processor, backlight technology and other details are also important.

The screen resolution determines how much information is shown on the display. It is measured horizontally and vertically in pixels. At low values, such as 640 × 480, fewer elements will be reflected on the screen, but they will be larger. When the resolution is 1920 × 1080, the monitor displays more elements, but they are smaller. Resolution modes for each display are different and depend on the video card, monitor size, and video driver.

How to make a resolution of 1920 × 1080

On a note! Windows 10 integrates support for 4K and 8K displays.

By default, the system selects the best display settings for your computer based on its monitor.

Optionally, you can manually change the screen resolution to Full HD for each desktop.

How to change the resolution to Full HD

Below, we'll share how to change the resolution to Full HD for each individual desktop, as well as all Windows 10 users.

On a note! Sometimes an attempt to change the image display quality can lead to the fact that the tiles of applications attached to the start menu will be empty. If this happened to you, then restarting the explorer should help.

In general, the whole operation to change the screen resolution comes down to the following steps:

Step 1. To open the display settings, follow point 1,2 or point 3:

Step 2. If your PC has multiple displays, select the one from the list (for example: "2") whose resolution you want to change (see screenshot below).

Note! If all of your displays do not appear, click on the Detect button. This is how Windows will try to find them.

Step 3. If you are not sure which number a particular display has, click on the "Identify" button (in the screenshot below). This will cause the system to briefly display the number of each display. However, this function appears only when multiple monitors are connected.

Step 5. Choose a screen resolution of 1920 x 1080 or Full HD.

Step 6. Select the display mode and screen resolution (custom).

Step 7. If you have multiple displays connected to your computer and you want to change the screen resolution for each of them, repeat the above step 4.

Step 8. When finished, you can close Options if you like.

Video - How to set the screen resolution to 1920x1080

This “highest” resolution appears to be the highest good. But high-definition television or HD video came to us relatively recently, so they have not yet had time to demand replacement in accordance with the technology update. Naturally, with a sometimes rather insignificant difference in price, for example, for FullHD and HD ready TVs, the consumer wants to know exactly what he is buying and whether he made a mistake in his choice. The displayed pictures do not always make it possible to determine: the image quality depends not only on the resolution, but also on many other factors (brightness, contrast, viewing angles of the screen, etc.), and subjective opinion is again marking time. Let's see what is the difference between the main baits of television and video equipment - FullHD and HD resolutions.

What is FullHD and HD resolution

HD Resolution Standard(High Definition) includes any resolution that exceeds the standard format (i.e. 720x576). Today, HD resolution (HD ready) means the minimum requirements for a resolution of 1280x720, but less common resolutions, for example, 1920x1440, are also referred to the high-definition standard. Marketing also introduces the HD ready designation to denote matrices capable of displaying the HD standard on a par with standard definition.
In fact, Full HD- This is HD with a resolution of 1920 × 1080, that is, higher than HD.

Comparison of FullHD and HD

What's the difference between FullHD and HD? The Full HD naming is not a quality standard - it is a marketing tag designed to attract shoppers and keep them from getting confused by the digital values ​​of the resolutions. There is a standard HD ready 1080p, corresponding to a resolution of 1920 × 1080, but not equivalent to Full HD: often video equipment technically does not correspond to the mentioned standard, being limited to compliance with the resolution. HD ready, on the other hand, is a standardized designation for receivers.
For the consumer, the difference between Full HD and HD is in the picture quality. High definition is due to the increase in detail by increasing the number of pixels of the screen matrix. Consequently, a Full HD picture contains more information than an HD or standard definition picture. According to experts, the difference in the amount of information can reach fourfold.
Also, matrices of Full HD displays are capable of displaying both a picture with a resolution of 1920 × 1080 and 1920 × 720, and a standard 720 × 576, while HD ready does not swing at a higher resolution. This does not mean that when playing a video of a different format, we will get a TV grid or "snow". HD displays increase the standard video resolution to the resolution of the installed matrix, the HD720 picture is displayed unchanged, and the HD1080 is reduced - again, to the physical capabilities of the matrix. Full HD-displays any resolution below 1920х1080 "reach" their own matrix. As a rule, large screens involve the reproduction of media content, so the picture quality will be of fundamental importance, and the choice remains with Full HD.
When it comes to scanning, HD means extremely progressive, although with a little distortion, such devices can reproduce 1080i (interlaced). FullHD assumes both interlaced and progressive scanning. This compromise makes it possible to receive a signal, for example, from a satellite without problems with data flow and channel capacity.
Today, the price range of television and video equipment has a very wide spread, so there is no need to talk about a clear advantage in the cost of one or another class of devices. However, most manufacturers, in addition to Full HD matrices, install powerful processors that can process images quickly, so if the diagonals are equal, such models can be significantly more expensive. Another important point: Full HD is not equal to HD1080p, so TVs and monitors that technically do not meet the quality standard can be labeled Full HD (without deceiving potential buyers), but such devices are much cheaper than those labeled HD1080p.

ImGist has determined that the difference between Full HD and HD is as follows:

The minimum resolution of Full HD matrices is 1920 x 1080, while HD is 1920 x 720.
The picture quality on Full HD displays is higher than on HD.
The HD ready standard imposes high technical requirements on technology (with the exception of the matrix resolution), the Full HD marking is actually responsible only for the resolution.
Full HD supports interlaced scanning without altering the picture.
Full HD may not meet the HD1080p quality standard.
Manufacturers often equip Full HD devices with powerful processors, which affects functionality and performance.

Full HD resolution did not provide the best picture quality in the history of the game for long. Today, Ultra High Definition is ubiquitous in desktops and laptops, making the hearts of gamers with the clearest 4K monitors beat faster.

But not so long ago we stood at the windows of electronics stores with open mouths and looked in amazement at screens with Full HD resolution. These stunning movements, these vibrant colors, this extremely sharp image!

However, this revolution did not have time to finally take place in all houses and playrooms, as the turn of the next came. Today, 4K is already at the start of the game, driving a 300 percent increase in pixel count, and illuminating monitors and gamers' eyes with incredible clarity.

The advantage of UHD is literally immediately striking: detailed gameplay, which, thanks to a brilliant picture, immerses the user right in the thick of the action, as well as rich colors and high contrast are convincing.

Will the transition to such a high resolution affect the gaming pleasure? Here, an explanation must be made right away: for devices with a screen up to 15 inches, the user will hardly be able to feel the difference between Full HD and Ultra HD resolution. The reason is that the distance to the screen when working on a laptop is usually 400–600 mm.

This is due not only to ergonomics, when you need space to perform actions on the keyboard and trackpad, but also to a comfortable view of the screen. A person perceives information better, seeing the entire display, and only in some cases, when it is necessary to examine something in detail, does he approach the screen by 200–300 mm. Therefore, the Ultra HD resolution is optimal for screens with a diagonal of 17 inches or larger.

4K and Full HD: Harsh Hardware Facts

Even the hottest game can fail due to lack of screen clarity. If the resolution meets the requirements, even hardcore gamers can be satisfied. In order to run smoothly when looking for the perfect hardware, you need to clearly understand the differences: Full HD is a high-definition standard for monitors, whose characteristics are 1080 pixels in height and 1920 pixels in width, which ensures that the image as a whole has about 2 million dots.

Ultra High Definition, also known as 4K, goes even further in this direction. The resolution is a total of 8.3 million pixels, reaching 2160 pixels in height and 3840 pixels in width seamlessly.

However, when determining the name, it was not a roughly rounded fourfold increase in the number of dots that was taken, but a professional film standard. A higher pixel count ensures a better picture and makes it possible to use larger displays without sacrificing image clarity.

Wait, that's not all!

Yes, the resolution is impressive for both Full HD and UHD. However, extremely sharp 4K images can do something else: rich contrast and rich colors push the boundaries of picture quality. Ultra HD can compete with Full HD for higher color fidelity without greyness and with deepest blacks.

Excellent uniformity of backlight distribution ensures that no dark spots will distort the image. Well, and, as they say, last but not least: thanks to the low response time, all videos and games from A (Action) to Z (Zombie) are perceived by gamers as a real miracle.

HDR10: how it differs from Dolby Vision

High dynamic range technology, or, is still rare in computer monitors. It increases the contrast by several times, making images more realistic and detailed. Night scenes in Full HD often look like black images, and with UHD + HDR, even in very dark scenes, a lot of detail can be discerned.

HDR has been successfully used in video games as well. There are various standards: HDR10, Dolby Vision, Advanced HDR, or HLG. Each has its own advantages and disadvantages. Displays with the Premium UHD logo as well as PS4 Neo game consoles and support HDR10 which opposes the Dolby Vision standard. Unlike HDR10, it requires its own very expensive hardware chip.

Dolby Vision has a 12-bit color depth and thus provides the best HDR effect, and also outperforms HDR10 with a 10-bit color depth. Roughly speaking, HDR10 is the standard for mainstream consumers, while Dolby Vision is a tidbit for wealthy users.

Name of the Game: Ultra HD in action

Enthusiastic gamers may gradually start to express concern as the gameplay benefits are not yet clearly articulated. Still, is there any point in 4K displays?

While this is a tricky question for TV enthusiasts, as the picture quality requirements are reduced by farther away from the screen, gamers who are constantly in close proximity to the display can enjoy the benefits of Ultra High Definition without any problems.

The combination of 4K and high-performance graphics delivers unmatched gaming experience. Flawless landscapes and characters, photorealistic explosions and the absence of "ladder" effects, without rough rendering of edges at lower resolutions - these are just a small part of what awaits you when immersing yourself in virtual worlds.

Particularly important for a smooth gaming session is the response time it takes for the monitor to change images. For the best result, a simple rule applies here: the less, the better. With rates of 20ms or more in fast action shooters, dropped frames will quickly become noticeable.

4K users, thanks to the fast image change and the absolute absence of ugly "stripes", will be able to experience the ultra-realistic and immersive atmosphere of the game. But with all this euphoria, you have to bear in mind the harsh facts about the equipment you need.

Carefully! An extremely clear conclusion!

The future will be filled with clarity as 4K is marching with its incredible resolution, rich colors and highly realistic picture quality. However, whether it should be an Ultra HD monitor or a Full HD version is entirely up to your individual needs.

While casual users or office workers can make do with the still-great Full HD capabilities, hardcore gamers will certainly need 4K graphics. Only in this case you will receive an extremely clear image of the elves' hair peacefully swaying in the wind, and the enemy's face riddled with scars and wrinkles.

However, for the dreams of realistic high-definition gaming to come true, you need to make sure you have the right hardware. But don't panic: a fourfold increase in the number of pixels does not mean a fourfold increase in costs.

Modern TVs are capable of working with various signal sources:
- Terrestrial or cable analog and digital television.
- Satellite television.
- DVD-players and camcorders.
- Computers, laptops, Flash drives, Internet.
- Decoders and receivers offered by ISPs or cable TV organizers

To implement a high-quality image, taking into account the need to transmit and store video information, various systems and standards for video signal formation have been developed at different times.

Standard Definition Television SDTV

SECAM and PAL color television systems popular in our country, widely used in air and cable broadcasting, transmit 625 lines and 50 half-frames per second in an interlaced way. Odd and even lines alternately. As a result, the visible image is formed from 25 full frames per second.

Interlaced display of a frame on the screen allows you to use half the video signal bandwidth, which is especially important for HF modulation in terrestrial analog television, therefore this method is widely popular in terrestrial and satellite broadcasting systems for television programs.

Due to the existence of a reverse path of the beam during the formation of frames and lines in televisions with a cathode-ray tube, some of the lines are not involved in image transmission, but are used to transmit technical information - color synchronization and data transmission in teletext mode.
In LCD or plasma TVs, the use of such a video signal in the popular PAL or SECAM systems, when scaling with a graphic controller, a decomposition standard is implemented 526i, in which 526 lines (out of 625 existing) are used to form the visible image. Index i indicates that the scan is interlaced.

The video signal of the NTSC system transmits 525 lines and 30 frames in 60 half-frames. Implemented in graphic format by the decomposition standard 480i.

High Definition Television HDTV

With the growing popularity of computers and LCD TVs, it became necessary to form images with a higher resolution, which contributed to the spread of the progressive (line-by-line) method of frame formation in TVs.
This is how video decomposition standards emerged for higher HDTV resolutions.
The standard record usually indicates the number of visible lines and the method of framing.
Index p- progressive corresponds to progressive scan with line-by-line display of the frame, or i- interlaced indicates interlaced scanning.
For example, the decomposition standard 720p indicates that the video signal consists of 720 visible lines and is generated line by line for progressive scanning.

Progressive scanning has certain advantages in image transmission quality, but requires a wider frequency bandwidth for HF modulation, therefore it is rarely used for transmitting an analog signal over the air.
When forming a VGA or SVGA video signal by a computer, only progressive scan was always used to display it on a monitor.
Decomposition standard 720p can be implemented in TVs with screen resolutions of 1280x720 or 1366x768 for a 16: 9 aspect ratio and at a resolution of 1024x768 for a 4: 3 aspect ratio. The remaining 48 lines are not involved in image formation and can be used for transmission of technical information or blanking during the retrace in TVs with a kinescope.

For a resolution of 1920 x 1080, 16: 9 aspect ratio, there are decomposition standards 1080i and 1080p, respectively for interlaced (i) and progressive (p) scans.
Decomposition 1080i it is currently used in the broadcast of many satellite channels transmitting as HDTV, where the modulation bandwidth is relevant.
Decomposition standard 1080p can be implemented in the formation and transmission of a video signal by computers, video cameras or DVD-players Blue-Ray.

It is worth recalling the existence of EDTV (Enhanced Definition) standards, which became a transitional stage from standard SDTV television to HDTV high definition television.
In the US, EDTV has been adopted by the CEA Electronics Consumer Association to denote digital decomposition standards 576p(PAL) and 480p(NTSC) with progressive scan.
In EDTV standards, the frame rate is 25 Hz for 576p and 30 Hz for 480p.
In Russia EDTV is known under the term "High Definition Television". According to GOST R 53536-2009, it implies the transmission of signals with line-by-line decomposition of the frame and the number of visible lines in the frame 720. Complies with the decomposition standard 720p.

When broadcasting a signal in digital format DVB-T, DVB-T2 or cable DVB-C, frequency modulation is not used, and frames are transmitted according to MPEG standards, so concepts such as frequency band and video signal decomposition are no longer relevant.

Full HD or HD ready?

You can often see logos on TVs Full HD or HD ready, also these inscriptions can be present in the technical characteristics and on the price tags of TVs. What do they mean?
A lot of controversial and dubious reasoning about this can be found on the Internet.

HD ready is a European standard that prescribes certain technical possibilities for the implementation of HDTV in televisions.

HD ready- provides support for decomposition standards 720p and 1080i.
This means that this TV is capable of accurately (pixel-for-pixel) displaying a signal with a resolution of 1280x720 with a frequency of 50 or 60 Hz and progressive scan, as well as with a resolution of 1920x1080 with a frequency of 50 or 60 Hz, but only with interlaced scanning.
Format 1080p(progressive scan) will be interpolated, therefore displayed on screen with some loss of quality.

HD ready 1080p- indicates the ability of the TV to support, in addition to the above-described modes for HD ready, also progressive scan in a resolution of 1920x1080. For this option, the term Full HD was introduced, that is, a complete set of all HD modes.

In some variants, Full HD logos can indicate the maximum capabilities of HDTV, for example:
Full HD 1080p- advertises the TV's ability to support all HD standards, namely: 720p, 1080i and 1080p for all possible TV resolutions and at any frame rate.
For details on the modes supported by the TV, it is better to check its specifications.

Ultra High Definition Television UHDTV

In August 2012, two more sets of 4K UHD TV digital television standards were adopted. 2160p and 8K UHDTV 4320p.
Decomposition TVs are already on sale 2160p with a resolution of 3840x2160.

To implement the standard 4320p so far, only demo samples exist, for example, provided by the Japanese company NHK, which developed the Super Hi-Vision broadcast format with support for 8K UHDTV resolutions.
One hour of uncompressed video in this format takes about 25 terabytes.
