4K and Full HD: how they differ and which is better?
Being carried away by the field of electronics, users notice the emergence of TV-devices with the help of which the image is shown in the Highest quality, with thin and huge displays. State-of-the-art technology provides everyone with the opportunity to enjoy gorgeous quality video with detailed images. With the advent of improved devices, buyers are puzzled which is preferable. 4K or Full HD? Which of the varieties is more rational?
Pros of 4K Instances
The first plus of 4K. comfortable watching TV at a short distance. The display of such an instance has a resolution that is recognized as ultra-high (about 8 million pixels).
This means that the picture is detailed to the maximum and looks more distinct when compared to previous TVs. The main advantages of 4K are:
- Distinct picture detailing, which is ensured by the use of proprietary technologies and an increase in the pixel concentration parameter. People can easily assimilate such a picture.
- Progressive scan rates. up to 120 frames / second. As a result. reducing the load on the eyes, they are not so tired, even if they sit in front of a blue screen for days.
- Many shades are displayed in depth.
- The dynamic range is increased. In the most lightened and darkened parts of the image, all details are reproduced very clearly. All shades and colors look clearer and more vibrant.
- Improved sound quality. 4K TVs have multi-channel audio.
Such TVs will arouse interest among fans of video games, because the image is extremely close to reality, which contributes to a complete deepening into the virtual space. In retail outlets, you can already find video games that support this format.
4K matrix creates a spatial image that is viewed by a person from all positions. To view high quality 3D images No 3D glasses required.
It is possible to watch channels on a 4K TV in a smaller format, but this will adversely affect the picture. contrast and clarity will suffer, the image will “stretch”.
Full HD
Full HD. a concept that means that the TV supports all high definition video formats up to 1920 by 1080. That is, if the matrix of the TV has a lower resolution, then Full HD is out of the question. Lower resolution matrices can display content in full HD720 quality. Such copies usually bear the inscription HD Ready, which can be translated as “ready for display” HD. Next, we will show the actual differences between TVs with and without the Full HD or HD Ready label.
- If the TV set does not have any mark, then even the available high-definition matrix does NOT guarantee support for high-definition video. In most cases, these instances are provided for the image of a conventional SD signal with an extreme increase in its resolution, to the numbers that the matrix supports. As a result, the Ultimate SD resolution will correspond to the physical resolution of the matrix.
- If the machine is marked HD Ready. this means it is capable of displaying high definition and standard definition video. That is, the resolution of the HD1080 signal will be reduced to the actual resolution of the matrix, the HD720 signal will be played “as is” or its resolution will be increased, the resolution of the SD signal will also be raised to the actual resolution of the matrix.
- If the device has a Full HD inscription. this means that it displays any signals. HD1080 quality signal is displayed “as is”, while the resolution of the remaining signals will be raised.
What to buy: 4K or Full HD?
It is problematic to give a clear answer to this question. State-of-the-art technology is slowly gaining acceptance in today’s market, but few are willing to use it. The reason for this is the high cost of 4K devices. Even if a person has the means to purchase an expensive model, he will not be able to use it to its fullest, because the content is limited.
Alas, the reality of our life and the domestic electronics market are NOT yet adapted for the use of ultra-modern devices and viewing files in such a high resolution. So the question of which TV to buy, 4K or Full HD, is logical.
Buying a 4K TV comes with a list of challenges. For its one hundred percent use, you will need an Internet with a solid speed and a specialized HDMI cable. The owner of a modern TV will need to spend time searching for and purchasing the desired content. Satellite channels provided for viewing in this format, in our state, practically comments.
The difference between 4K and Full HD
Progress does not stand still, especially in the field of electronics. And if you are thinking about buying a new TV, it is rational to find out what formats are popular now. According to our research, 4K and Full HD TVs are most often bought. What’s the difference? What’s better? Better? Cheaper? You will find out all the answers in this article.
Main characteristics of Full HD
To understand the difference in the characteristics of these formats, you need to understand what resolution is.
Important! Screen resolution. this is the size of the image in pixels but the physical size of the screen.
Many have heard of the formats of the playable video, defined in pixels. This indicator is defined in the lower right corner of the viewport. One of the numbers is displayed there: 360, 480, 720, 1080. This is the number of pixels in the picture vertically.
Thus, full HD resolution corresponds to 1080 pixels vertically and 1920 horizontally. It is worth noting that the format is one level lower, HD, has 720 vertical and 1280 horizontal. Accordingly, Full HD provides a sharper image in comparison with the previous generation.
Main characteristics of 4K
Having a general idea of the resolution, you can understand the characteristics of 4K. The main indicator by which its characteristics are assessed, pros and cons is the number of pixels on the screen vertically and horizontally.
4K is the next generation after Full HD, therefore, its characteristics in terms of the number of pixels are increased. So, the following indicators correspond to this resolution: 2160 vertically and 3840 horizontally. Therefore, it gives a clearer detail, respectively, a high-quality picture.
On a note! 4 k has another name. ultra HD.
It is worth noting that video and screen resolutions are closely related. If the screen only supports the Full HD maximum, then a higher quality video will not be played at high rates. The system works the same way and vice versa: if you play 1280×720 video on a 4K-enabled screen, its quality will NOT change, and there will be no point in supporting high quality.
What’s the Difference Between 4K and Full HD
The main differences between the considered formats are as follows:
- Pixel count: 4K has more vertical and horizontal pixels.
- Detail: in a new generation format, a sharper picture and a higher degree of detail.
- Display colors: in 4K they are richer and deeper.
The overall difference is in image quality. If we consider TVs with supported resolutions, then several more indicators come into force:
- Price: 4K TVs are more expensive.
- Content volume: Despite the rapid development of technology, 4K content is still quite small.
When choosing between These two formats, pay attention to the characteristics you personally need. Is the price important to you? Or does quality prevail? If you want to get a better and sharper image, as close to reality as possible, 4K is definitely for you.
Full HD resolution: what it is and how it differs from HD, 4K
When choosing a TV, the consumer always directs attention to the labeling and technical characteristics. A special subject for discussion. screen resolution. Will you overpay for a 4K TV or save money and buy a Full HD model? The answer to this question depends on many factors: the budget, the nature of using the TV, the expected result. Few people know what Full HD is, so it’s time to figure it out. This is the only way to make a competent and balanced decision.
Full HD story
Resolution reflects the size of the image displayed on the screen. This parameter is measured in points, that is, pixels. The higher the resolution, the higher the quality and the better the detail of the picture. Models that support HD format are available today. High Definition: HD stands for High Definition. Resolutions starting from 720 × 576 pixels fall under this standard.
Over time, the unspoken rule was adopted that the resolution is HD. 1280 × 720 pixels. The quality of displays, screens, matrices and technology, in principle, increased, the developers introduced innovative technologies into the production process. The natural result of the technical revolution. appearance in 2007 Full HD.
New standard screen resolution. 1920 × 1080 pixels. The pixel density has increased significantly, resulting in improved image quality. The standard has been actively implemented since 2007. Improved detail allows you to see even small image elements.
There is such a thing as amorphous Full HD. Screen resolution. 1440 × 1080 pixels, but the pixel is not square. In regulatory documents, this standard is referred to as an abbreviation for HDV. The permit has been in use since 2003. HDV marking is quite common in various models of video equipment. Fun Fact: The first high-definition movies to come out on Blu-Ray and HD DVD are featured in HDV.
The main difference between Full HD and other standards. resolution that directly affects image detail. The developers are constantly working to improve this parameter, providing a fully immersive viewing experience.
What does Full HD mean?
The standard definition (SD) picture has a resolution of 720 × 576 pixels. Full HD resolution. 1280 × 720 pixels, this is a high definition image. The resolution of the new standard is almost twice that of the previous one. HD 1080 format resolution.120 × 1080 pixels. There are also several subgroups of HD 1080: progressive, interlace.
The peculiarity of the progressive subformat is that video output is carried out instantly, and not sequentially. Displaying content according to this principle prevents the appearance of the Comb effect, the maximum image detail is preserved. Full HD. it is a high definition video format. Base screen resolution. 1920 × 1080 pixels. The aspect ratio is 16: 9.
Comparison of HD and Full HD
Full HD is hardly an independent standard. This is a marketing tool that Sony used in 2007 to attract the attention of its target audience to its products. Other manufacturers supported this initiative and began to actively exploit the advertising tag. Therefore, when you see the HD Read mark, it means that the screen resolution size is 1280 × 720 pixels, and if Full HD. then 1920 × 1080 pixels.
Adhering to the point of view that Full HD is NOT a full-fledged standard, we can call it HD modification, which has the best picture quality. Noticeably higher pixel density. Users are always guided by the screen resolution: the larger it is, the higher the image clarity. An increase in the number of pixels of the matrix really allows you to broadcast the most detailed picture.
Full HD costs more than SD or HD. Research results confirm that FHD is characterized by improved picture quality, which exceeds the previous standards by about 4 times.
Full HD technology can also be used to play content with other resolutions. Matrices automatically Attempt to pull up low resolution to optimal performance. Televisions, not Full HD capable, but not capable of reproducing high definition images.
How is Full HD different from other standards? There are several fundamentally important points. For example, the simultaneous use of 2 types of scan is implemented:
- Interlaced: dividing the frame into 2 fields, which are composed of lines. The image is displayed on the screen in stages;
- Progressive: the entire frame appears immediately on the screen. Provides excellent display of dynamic scenes, the image does NOT blur.
If we talk about the popularity of technology, the level of sales is higher for models with the Full HD label. However, manufacturers are NOT giving up on HD, since such TVs are much cheaper, and there is also a demand for them. This resolution is also supported by many budget smartphones.
Most of the popular TV set-top boxes. these are Full HD or 4K models. This type of device can be connected to an HDTV for high quality content playback.
What HD and Full HD have in common
Full HD resolution. 1920 × 1080 pixels, which is the main difference from the previous standard, but there are a number of similar aspects:
- It’s the same format, the only difference is that Full HD has a higher screen resolution;
- In both cases, interlaced scanning of the frame can be used;
- They can be used to reproduce content with a resolution of 720 × 576 pixels;
- HD and Full HD TVs Equipped with HDMI, DVI.
What is the fundamental difference between HD and Full HD
- Key difference. screen resolution, which affects the quality of the broadcast image.
- Full HD TVs predominantly support progressive scanning or its combination with interlaced, which allows you to maintain clarity during the broadcast of dynamic scenes.
- Aspect ratio. one more feature. Full HD has a 16: 9 aspect ratio.
- For many consumers, the key difference between Full HD monitors and TVs is price. The cost of this technique is much higher than HD.
4K comes on your heels
In 2012, the first models of technology supporting 4K Ultra HD began to appear. Key benefits. maximum detail, high screen resolution (3840 × 2160 pixels). A few years ago, it was Full HD technology that was the priority option for the average consumer, but now the situation is changing in favor of Ultra HD. The developers managed to solve two problems at once, which held back the massive use of 4K. First, the price has dropped. Secondly, there is much more content.
From a technical point of view, the 4K standard is significantly superior to Full HD. The user is offered full immersion in viewing due to the broadcast of high-quality images with maximum detail. Over time, Ultra HD will completely displace its predecessor from the market. However, for sure, this will not happen today.
There is a new problem. Large 4K TVs are extremely expensive. Therefore, some users still use Full HD technology. It is not excluded that this barrier will also be overcome in the near future. If your budget allows, you can safely buy a 4K TV: such an investment will pay off extremely quickly.

What is FullHD
This picture quality format for television programs replaced SD in 2007, changing the resolution from 720×480 to 1920×1080 pixels, and the aspect ratio from 4: 3 to 16: 9.
Advantages
FullHD TVs have the following benefits:
- Picture 4 times more detailed than HD devices.
- No distortion or defects in fast moving scenes thanks to progressive scan.
- Huge selection of models and low price.
- A huge number of films, cartoons, TV series in FullHD quality.
- The ability to watch digital TV and play video games in high quality.
disadvantages
The disadvantages of such devices include the lack of 3D support and the rapid obsolescence of the format.
What is 4K
4K. FullHD development. It differs by twice the length and width of the image in pixels. It got its name from the length of the professional frame in pixels. 4096 or 4K. 4K format is divided into 4 types:
- Full frame: 4096×3072.
- Academic: 3656×2664.
- Cased: 3996×2160.
- Ultrahd: 3840 × 2160.
The first 3 are used when creating and editing movies. For the average user, the latter type is interesting, since all 4K TVs support UltraHD.
Advantages
Ultrahd TVs have the following benefits:
- High-quality and bright picture. This is achieved thanks to 4 times more pixels and increased color depth from 8 to 12 bits compared to FullHD.
- The refresh rate of the image on the screen increased to 120 Hz. This means that the video will play smoothly, and the eyes should not be tired from long viewing.
- The ability to watch videos in FullHD, HD or SD quality without noticeable picture distortion. This feature is called scaling or upscaling. For this, algorithms are used to fill in the gaps with additional pixels, reducing graininess and smoothing the transition from one color to another.
- The minimum distance to the device for comfortable viewing. 1.5-2 meters for models with a diagonal of 55 inches or more. This allows you to place a large TV in a small room and NOT worry about pixels being visible from a short distance.
- The format is promising. Fullhd is gradually becoming a thing of the past and is being replaced by 4K. It will be relevant in 3-4 years.
- There’s a lot to see on 4K TV. These are digital television (UltraHD package from Tricolor-TV), Youtube videos, online cinemas (Megogo, Ivi), Netflix series.
disadvantages
The disadvantage of such devices is only 1.high price.
Which TV to choose: FullHD or UltraHD
It depends on the intended use. If you only plan to watch television and movies, there are high requirements for picture quality. Diagonal Will not be more than 50 “, then a FullHD TV will be enough.
When choosing, be sure to find the notes that the device supports this format.
Otherwise, you may face a situation that a TV set with a resolution of 1980×1080 can only play SD quality video. Mention of HD Ready support indicates only HD playback, not FullHD.
If you want to watch movies and play video games in maximum quality, then you should think about an UltraHD TV. It will provide not only a bright and vivid picture, but also high-quality sound. If you have a 4K TV box running Android or another signal source, you can save a little, bought a device without Smart TV function.
How 4K TVs differ from FullHD
The FullHD standard has a resolution of 1920 × 1080 pixels, which makes the picture contrast and clear. For comfortable viewing, you must observe the minimum permissible distance from the TV screen. Otherwise, the image will be blurred, and it is harmful for vision.
The larger the diagonal, the further you need to be from the screen. If the diagonal is 32 inches, then the distance to it should be at least a meter. For a diagonal of 55 inches, the distance should be at least 2.5 meters.
Techniques with such a resolution are quite common now on the market and have an undoubted advantage over previous technologies. The popularity of the “high definition standard” earned during its existence is explained by the following advantages:
- High picture characteristics;
- A graphics processor with excellent technical properties;
- There are no distortions and roughness on the TV screen;
- Impressive assortment of devices in different price categories.
The disadvantages of Full HD include:
- Impossibility to view the image in 3d on some models;
- Presumptive obsolescence.
Features of the 4K standard
This innovative standard with a resolution that virtually eliminates harmful effects on the human visual organs is already engaging its audience. 4K TV sets are not produced with a single resolution, but it depends on the TV standard.
| Naming | screen | Areas of use |
| Wide-screen | 4096×1716 | For watching movies |
| Academic | 3656×2664 | Cinematic production |
| Cached | 3996×2120 | Into the cinema |
| DCI | 4096×2160 | In camcorders, smartphones |
| Ultra HD | 3840×2160 | all over the place |
The difference between 4K and UHD is that the former is considered a professional production standard, which is used in coordination with the subgroups above. UHD is applicable to consumer screen and ultra-high definition television broadcast.
The most significant advantage of 4K over the fhd version is expressed in higher pixel density. The pluses also include an increase in the color range and naturalness of the picture.
The fact of increasing the number of frames to 60 fps is considered another feature of 4K.
Differences of FullHD from other standards
The difference between 4K and FullHD
These latest technologies have already taken the place of the previous ones, but if full HD has firmly won the sympathy, then 4K is just beginning to gain popularity. In the 4K versus FullHD dispute, the main difference between the first and the second is the fourfold increased number of pixels.
The comfortable viewing distance has been reduced. For example, when watching TV with 65 inches, the distance from the TV screen should be at least one and a half meters.
4K has significant advantages over the earlier Full HD:
- An impressive level of detail, pixels. invisible;
- Optimal frame rate;
- Impressive color depth;
- Unlimited gaming possibilities.
In addition to the undeniable advantages of 4K, it also has some Notable disadvantages:
- High quality but expensive devices;
- The media space is not sufficiently adapted to the latest formats.
Technically, 4K is much better than fhd. The viewer is completely immersed in the action viewed on the TV screen, which ensures the broadcast of a high-quality, highly detailed image. 4K will gradually replace fhd, but this will not happen in the near future.
Fullhd TV Samsung V32F390SIX
The first reason holding back the widespread use of the latest technology is the too high cost of 4K TV sets with a large diagonal. For this reason, many people still use fhd.
According to experts’ calculations, in order to clearly identify the advantages of 4K in relation to full HD, the dimensions of the TV screen should be much larger and must be observed at close range. Even taking into account the fact that the difference in pixels is four times the size, most users do not always feel how these formats differ. This is due to the limited ability of ordinary human vision to recognize.
Usually people are about 2.7 meters away from the TV when watching. In order to evaluate what advantages 4K resolution has, you need an 84-inch TV screen, and the distance to it while watching should be about 1.6 meters.
Therefore, even in a small room, you can install a large 4K TV without fear that due to the large pixel size, watching movies will not be comfortable enough.
The difference between 4K picture and FullHD
Gradually, developers are removing two limiting factors for the widespread adoption of 4K. the price goes down and the amount of content increases.
The main advantage of 4K. in reducing the distance for a favorable TV viewing. The wearer can sit much closer to the screen than would be possible with the introduction of the Full HD standard.
In addition, the advantage is the expansion of the color space, which adds naturalness and contrast to the image.
Which TV to choose 4K or FullHD?
If you plan to set up a free package of channels with limited financial resources, you can purchase a TV receiver that supports FullHD. To watch movies, TV series, videos, and if it is essential to have a perfectly high-quality picture, then it is quite possible to buy equipment that supports 4K. It will be a profitable and long-term investment.
Even despite the insufficiently prepared media space, experienced users will appreciate the image level. The technology will appeal to those who want to discover optimal quality and get new sensations.
The increased color depth (over a billion) of the latest 4K Ultra HD Premium TV with wider dynamic range allows for increased picture quality. This possibility is indicated by the presence of a logo on the case, which guarantees compliance with the highest quality characteristics. You can find out whether the TV supports 4K from both the information on the package and in the instructions.
4K TV Sony KD-65XF9005
This standard is applicable to many of the world’s most famous TV manufacturers. Panasonic, LG and Samsung, and content providers like 20th Century Fox, Netflix, Warner Bros. Sony does not use this logo even though the image standard has been fully negotiated.
Even if you have already made the decision to purchase a new 4K TV, you will need to make a hardware upgrade to get the full effect of your purchase. The presence of existing devices, cables, related broadcasting services will NOT allow you to hope to view the highest quality image.
It is likely that you will need to contact the second provider of digital TV broadcasting, the Internet, and change all cables on the peripheral equipment, if any. Blu-ray player replacement will be required in order for new players to play higher resolution video materials.
A TV diagonal size of over 84 inches and a distance of less than two meters is necessary in order to clearly distinguish between 4K and full HD. If there is a long distance to the screen, and the dimensions of the TV screen are not large enough, the difference will become completely imperceptible. It follows from this that if there is no particular need to purchase a TV with a large diagonal, then there is no point in spending extra money on a model that supports 4K. Full HD may well satisfy the needs of owners for home viewing.
What does 4K uhd TV mean? Which is better UHD or 4k?
