— Sony X1. The Sony X1 processor is used in Sony TVs from several series: XH and XG. Such TVs occupy several niches at once: the low-cost category and the middle class. The most affordable models display a 4K resolution picture without support for high dynamic range (HDR), more advanced models use 4K HDR. Basically, these are simple models that are designed only for watching videos. For dynamic games, TVs with such a processor are less suitable.

— Sony X1 Extreme. The Sony X1 Extreme processor is 40% more powerful than its predecessor, the Sony X1, and is designed to work with 4K HDR images. Working with HDR dynamic range makes it possible to display a realistic picture of increased quality on the screen. TVs with the Sony X1 Extreme processor are mid-range and high-end models. The image qualit is improved by supporting dynamic backlighting. An important feature of the Sony X1 Extreme is the use of two independent colour rendering databases (Dual database processing). Object-based HDR remaster technology analyzes the image displayed on the screen, matches colours with a database and adjusts them for viewing on a particular TV. Thanks to Super Bit Mapping 4K HDR, colour transitions become smoother and more natural, making the picture even more realistic.

— Sony X1 Ultimate. The Sony X1 Ultimate processor can handle both 4K (3840 x 2160) and 8K HDR (...7680 x 4320) images, depending on the screen size. TVs with such a processor provide a picture with the deepest detail and the highest quality rendering of textures. TVs with the Sony X1 Ultimate processor are mostly advanced models from the middle and expensive segment. Such TVs provide the effect of complete immersion in the atmosphere of the video being watched. Sony X1 Ultimate supports X-Reality PRO technology with an exclusive database of colour reproduction samples. Even when displaying low-resolution images on a TV screen, the picture quality is automatically upscaled to 8K (4K) with HDR High Dynamic Range. There is support for X-tended Dynamic Range PRO technology, which distributes the backlight in accordance with the displayed scenes. Dynamic backlighting improves contrast and makes the picture as bright as possible, while blacks are more saturated than ever.

— Sony Cognitive XR. TVs with Sony XR processor are capable of displaying a picture in 4K resolution at 120 Hz and 8K at 60 Hz. These are high-tech models operating under the control of advanced artificial intelligence. The Sony XR is one of the world's first "cognitive" processors. He processes the video and audio components of broadcasts to improve the quality of the image and sound, which creates a realistic picture of what is happening on the screen. The software algorithms of the processor process information about audio and video in a single stream. The manufacturer claims that the processor works akin to the human brain and goes beyond the capabilities of ordinary artificial intelligence algorithms.

— LG. The hierarchy of television image processors from LG includes several large Alpha families: α 5, α 7, α 8, α 9 and α 11. Each of them is described in more detail in the corresponding help paragraphs:

— LG α 5. Alpha 5 processors are used in the brand’s inexpensive TV panels and perform minimal image processing. They cover a basic range of tasks such as improving colour reproduction, upscaling video to 4K and creating surround virtual sound.

— LG α 7. Processors from the Alpha 7 line are found on board mid-range LG TVs with NanoCell and OLED matrices. Their advanced functionality includes automatic adjustment of image and sound parameters in accordance with the broadcast genre, as well as automatic adjustment of brightness and tones to suit the conditions of the surrounding space.

— LG α 8. The Alpha 8 family is the true “golden mean” from LG. The debut of α 8 took place in 2024, and such processors are installed in the brand’s TVs with NanoCell and OLED panels. They are equipped with improved noise reduction and sharpening algorithms, support for Dolby Vision and other premium HDR formats (in most models), and advanced artificial intelligence functions for increasing image and sound quality in real time.

— LG α 9. LG's flagship TVs are equipped with α 9 rank processors - in fact, they rely on deep machine learning algorithms to analyze the genre of broadcast video content and adapt image and sound parameters to it. Alpha 9 processors work with all applicable specifications of high dynamic range technology in LG TVs and have a professional sound identification system.

— LG α 11. Alpha 11 processors will be installed in top models of LG OLED TVs starting in 2024. They are capable of working with frame formats up to 8K, while providing improved image scaling algorithms. The emphasis in the line of processors is on the highest computing power and developed functionality of AI algorithms for the finest adaptation of picture and sound.

Note that with each subsequent edition, LG image processors increase functionality. Their generations are designated by the prefix Gen with the serial number of the generation.

— Samsung Crystal 4K. The Samsung Crystal 4K processor is used primarily in Samsung's Crystal UHD series TVs. This category of TVs has an affordable price. These are simple models, the screen of which produces a picture in Ultra 4K resolution. The performance of the Samsung Crystal 4K processor is enough to bring the colour quality to the level of HDR. Of the technologies used, we can note the Contrast Enhancer and Dynamic Crystal Color, thanks to which the contrast and brightness of the image are fine-tuned.

— Samsung Quantum 4K. The Samsung Quantum 4K processor is used in Samsung TVs with QLED backlighting. High performance makes it possible to scale the image of Full HD to the level of 4K, and in the high dynamic range of HDR. The Samsung Quantum 4K processor features unique Quantum HDR technology, which makes the image more detailed, richer and more expressive. The processor supports Dual LED dynamic backlight technology, with which the picture acquires extreme contrast and at the same time high brightness. Also, the TVs have a special game mode Real Game Enhancer+ with support for AMD FreeSync technology.

— Samsung Quantum 8K. The Samsung Quantum 8K processor has been used in Samsung QLED TVs since 2020. Models in this series are capable of reproducing 8K HDR images, and a picture of such high quality can be obtained even from a source with a resolution of 4K to Full HD. Usually, these are top-level models. TVs of this class can be used as part of a professional home theater. Deep detailing of the picture guarantees complete immersion in the video content. Artificial intelligence QLED TV is responsible for image processing.

— Samsung NQ4 AI. Intelligent processor that provides high quality images and sound using artificial intelligence technologies. Used in mid-range Samsung TVs with OLED and Neo QLED matrices, it provides work with frame formats up to 4K (including image scaling from lower resolutions in real time). The processor supports flexible Quantum Matrix backlight control, and thanks to the AI ​​Customization function, the TV can independently determine the genre of video content, adjusting the brightness and contrast settings to achieve the effect of complete immersion in what is happening on the screen.

— Samsung NQ8 AI. Top-level processor found in flagship 8K Samsung Neo QLED TVs. Relying on machine learning algorithms and a built-in NPU neural engine, the processor guarantees a great video viewing experience regardless of the input source. Samsung NQ8 AI supports real-time upscaling to 8K, ensures smooth and clear depiction of fast movements in the frame thanks to AI Motion Enhancer Pro, and Real Depth Enhancer Pro allows viewers to immerse themselves in the action on the screen. In parallel, the processor is tasked with processing multi-channel audio, optimizing images in games and for each scene, depending on the user’s preferences.

Note that Samsung NQ4 AI and NQ8 AI processors were released in several generations, designated by the Gen prefix with a serial version number. The newer the edition, the more advanced the processor is.

– Philips P5 Perfect Picture. The Philips P5 Perfect Picture Processor is used in Philips OLED TVs. The processing power of the processor is enough to reproduce the 4K image. In older models, an extended dynamic range of HDR colours is found. TVs with the Philips P5 Perfect Picture processor cover several cost categories at once, the low-cost segment and the average price range. A high-quality picture is displayed on the screen of such models, but, usually, it falls short of the reference Ultra 4K HDR, since this requires a more professional matrix. The P5 Perfect Picture processor is the first Philips CPU to use artificial intelligence. Philips P5 Perfect Picture supports technologies such as Dolby Vision, HDR10+, Perfect Natural Motion and Micro Dimming Pro.

– Philips P5 Pro Perfect Picture. The Philips P5 Pro Perfect Picture Processor is used in Philips TVs with enhanced OLED. Models with this processor are capable of displaying an image in Ultra 4K HDR resolution. Usually, it is found in advanced class TVs. Philips P5 Pro Perfect Picture processor TVs use a machine intelligence neural network interface. Google Assistant and Amazon Alexa voice assistants are supported. The processor uses the following image and sound technologies: Dolby Vision, Dolby Atmos, HDR10+, Micro Dimming Perfect and Wide Color Gamut.

— Edge LED — side backlight of the matrix. In this case, the LEDs are distributed around the perimeter of the screen. To evenly distribute the backlight, the background of the matrix has a special reflector. An important advantage of TVs with Edge LED backlighting is the minimum thickness of the device. Among the shortcomings, one can note the presence of glare at the edges, which appear under certain conditions. Glare may be visible in scenes where dark hues predominate.

— Direct LED — rear matrix backlight. In this case, the LEDs are evenly distributed over the entire screen area. The Direct LED backlight makes the image contrast and bright at the same time. TVs with this technology have good colour reproduction. Among the shortcomings can be noted increased power consumption and increased dimensions. Additionally, such TVs have a large delay (Input lag), which is why Direct LED backlit screens are poorly suited for dynamic games.

— FALD (Full-Array Local Dimming) is a backlight technology widely used in LG TVs. A close analogue of FALD is the Direct LED backlight. The LEDs are also evenly spaced across the entire surface of the matrix, but FALD technology provides a bright, colour-rich image with high contrast. Another distinctive feature of FALD is the ability to reproduce natural blacks. When black is displayed on the screen, the LEDs are turn...ed off in groups, by sector, which allows to make black extremely saturated. Of course, the abundance of LEDs on the matrix makes the TV more massive, and at the same time heavy. The appetite for electricity in such models is above average.

— Mini LED. Screen backlight system on a substrate of reduced LEDs (hence the Mini prefix). On the same plane of the TV panel, the number of LEDs has increased several times, if we draw parallels with traditional LED systems. As a result, the canvas with Mini LED backlight has many times more local dimming zones of the picture (Local Dimming), which is necessary for the correct operation of the extended dynamic range image technology. For playing HDR content, Mini LED systems are much better than ordinary LCDs.

— Dual LED. Proprietary backlight system used in Samsung TVs. The technology involves illuminating the image on the screen with two types of LEDs: one emits light in a cold spectrum, the other in a warm one. The Dual LED enhances colour reproduction and enhances detail contrast by adapting the colour tone of the picture according to the content on the screen.

Screen resolution - its size in pixels horizontally and vertically. Other things being equal, a higher resolution provides better image quality, but such a screen costs more and requires relevant content.

The set of resolutions found in modern TVs is quite extensive, but they can be roughly divided into several groups: HD, Full HD, Ultra HD 4K, Ultra HD 5K and Ultra HD 8K. Here are the main features of each option:

— HD. Screens designed for HD 720p. The standard frame size in such a video is 1280x720, however, for a number of reasons, most HD TVs have somewhat larger sizes — 1366x768. In addition, this category usually includes models with resolutions from 1280x768 to 1680x1050, as well as 1024x768 screens. In general, HD 720p resolutions are mostly found on low-cost TVs with relatively small screens.

— Full HD. TVs designed for Full HD 1080p video, with a frame size of 1920x1080. Most models from this category have exactly this screen resolution — 1920x1080; other options are noticeably less common — in particular, 1920x1200 and 2560x1080. In general, Full HD screens provide good detail at a relatively low cost, making them extremely popular in mid-range models and inexpensive large-format TVs.

— Ultra HD 4K. This format provides different options in resolutions, however, for TVs, the actual stan...dard is 3840x2160, other options are almost never found. In general, this is a fairly high resolution, which is typical mainly for premium models; a common feature of such models is the large size — from 40" and more.

— Ultra HD 5K. The Ultra HD image format is more advanced than 4K, but it is extremely rare in TVs — these are mainly ultra-wide models with a resolution of 5120x2160.

— Ultra HD 8K. A standard that assumes a size of about 8K pixels horizontally; one of the options for this resolution, found in TVs — 7680x4320. Thus, UHD 8K is twice the size of 4K on each side and four times the total number of pixels, resulting in extremely sharp and detailed images. On the other hand, such screens are very expensive, despite the fact that nowadays even 4K is already considered a very advanced standard. Plus, there are not many video devices and content that meet this standard. Therefore, 8K TVs are still extremely rare, they include mostly high-end flagship models with a size of at least 65".

TV support for Upscaling function. This feature is only available on models with 4K and 8K resolution screens.

Upscaling to 4K allows you to increase the resolution of the original “picture” to 4K (3840x2160), if it was initially lower - for example, viewing a movie in 4K that was originally recorded in Full HD (1920x1080). In this case, we are not just talking about “stretching” the image to fill the entire screen (all TVs are capable of doing this), but about special processing, thanks to which the actual video resolution is increased. Of course, such video will still be inferior to content originally recorded in 4K; however, upscaling provides a noticeable improvement in quality compared to the raw signal.

Upscaling to 8K works on the same principle, only relevant for 8K TVs.

TV support for high dynamic range technology — HDR.

This technology is designed to expand the range of brightness reproduced by the TV; Simply put, an HDR model will display brighter whites and darker blacks than a regular TV. In fact, this means a significant improvement in colour quality. On the one hand, HDR provides a very "live" image, close to what the human eye sees, with an abundance of shades and tones that a normal screen cannot convey; on the other hand, this technology allows to achieve very bright and rich colours.

However for the full use of this feature, you need not only an HDR TV, but also content (movies, TV broadcasts, etc.) that was originally created for HDR. Also note that there are several different HDR technologies that are not compatible with each other. Therefore, when buying a TV with this feature, it is highly advisable to clarify which version of HDR it supports (HDR10, HDR10 + or Dolby Vision). And the following are found:

— HDR10. Historically the first of the consumer HDR formats, less advanced than the options described below but extremely widespread. In particular, HDR10 is supported by almost all streaming services that provide HDR content, and it is also common for Blu-ray discs. Allows to work with a colour depth of 10 bits (hence the name). At the same time, devices of this format are also compatible wi...th content in HDR10+, although its quality will be limited by the capabilities of the original HDR10.

— HDR10+. An improved version of HDR10. With the same colour depth (10 bits), it uses the so-called dynamic metadata, which allows transmitting information about the colour depth not only for groups of several frames, but also for individual frames. This results in an additional improvement in colour reproduction.

– Dolby Vision. An advanced standard used particularly in professional cinematography. Allows to achieve a colour depth of 12 bits, uses the dynamic metadata described above, and also makes it possible to transmit two image options at once in one video stream — HDR and standard (SDR). At the same time, Dolby Vision is based on the same technology as HDR10, so in modern video technology this format is usually combined with HDR10 or HDR10+.

The nominal power of the sound produced by the TV's sound system.

The larger the screen and the greater the estimated distance to the viewer, the more powerful the sound system must be in order to be heard normally. Manufacturers take this moment into account, moreover, most often they also provide a solid volume margin. So if a TV is bought for home viewing in a quiet, calm environment, you can not pay much attention to the sound power: it is guaranteed to be enough for such a usage. It makes sense to specifically look for models with high-power speakers for a noisy environment — for example, a cafe or other public space. Detailed recommendations on this matter can be found in special sources, but here we note that even in such cases, connecting external speakers can be a good alternative.

A decoder can be broadly described as a standard in which digital audio (often multi-channel) is recorded. For normal playback of such sound, it is necessary that the corresponding decoder is supported by the device. Dolby Digital and DTS were the first in multi-channel decoding, gradually improving and introducing new features. The final stage for 2020 is Dolby Atmos and DTS X decoders.

– Dolby Atmos. A decoder that uses not a rigid distribution of sound across channels, but the processing of audio objects, due to which it can be used with almost any number of channels on a reproducing system — the sound will be divided between channels so that each audio object is heard as close as possible to its proper place. When using Dolby Atmos, ceiling speakers (or speakers facing the ceiling) are highly desirable. However, in extreme cases, you can do without them.

— DTS X. An analogue of the Dolby Atmos described above, when the sound is distributed not through individual channels, but through audio objects. The digital signal contains information about where (according to the director's intention) the object audible to the user should be and how it should move, and the processor of the reproducing device processes this information and determines exactly how the sound should be distributed over the available channels in order to achieve the required localization. Thanks to this, DTS X is not tied to a specific number of audi...o channels — there can be as many as you like, the system will automatically divide the sound into them, achieving the desired sound. Also note that this decoder allows you to separately adjust the volume of dialogues.

Types of digital tuners (receivers) provided for in the design of the TV.

Such tuners are necessary for receiving digital TV broadcasts; for normal operation, the broadcast standard must match the type of tuner (with some exceptions, see below). Note that the receivers are also available as separate devices; however, it is easier (and often cheaper) to buy a TV with a built-in tuner of the desired format. In modern TV you can find terrestrial tuners DVB-T2, cable DVB-C and satellite DVB-S and DVB-S2, here are their main features:

— DVB-T2 (terrestrial). The main modern standard for digital broadcasting. Such broadcasting has a number of advantages over traditional analogue broadcasting: it allows higher resolution and multi-channel audio transmission, with better sound and picture quality, and this quality is fully preserved until the signal weakens to a critical level. However, in some countries digital terrestrial broadcasting is just being put into operation, so it will not hurt to check the availability of DVB-T2 coverage in your area.

— DVB-C (cable). The main modern standard for digital broadcasting in cable networks. Despite the advent of the more advanced DVB-C2, it still continues to be widely used, and most likely this situation will not change for a long time.

— DVB-S (satellite). The first...generation of the digital DVB standard for satellite broadcasting. Nowadays, it is relatively rare due to the advent of a more advanced DVB-S2, which is also backwards compatible with the original DVB-S.

— DVB-S2 (satellite). The most advanced and popular of today's digital satellite broadcasting standards. Being the heir to DVB-S, has retained compatibility with it; therefore, manufacturers often limit themselves to installing only a DVB-S2 tuner on their TVs — it allows you to receive both major satellite broadcast formats.

Among the features of the TV, first of all, it is worth noting its communication features, which include AirPlay 2, Wi-Fi(in particular Wi-Fi 5 and Wi-Fi 6), Miracast, Chromecast, Bluetooth. As a control, in addition to the classic remote control, there can be voice control, voice assistant. As well as special features in the form of Ambilight from Philips. More about them:

— Airplay. TV support for AirPlay technology, usually in the AirPlay 2 version. Initially, this technology was created to broadcast multimedia content from Apple gadgets (iPhone, iPad, etc.) to external devices, including TVs. At the same time, it allows not only to play such content, but also provides many additional features — broadcasting additional information (title of the sound track, album cover), playback control from the TV remote control, etc. In AirPlay 2, in turn, the "multi-room" format was added — the ability to simultaneously broadcast several signals to compatible devices installed in different places at home (for example, a movie on a TV and an online radio programme on sound system in the kitchen). In addition, in this version, support for voice control via Siri has appeared and...a number of technical issues have been improved (in particular, buffering of streamed content).

— Wi-Fi. The presence of a built-in Wi-Fi module in the TV; the supported version of this technology can also be specified in this section. Nowadays, Wi-Fi can be used both for wireless access to the Internet and local networks, as well as for direct connection with other devices (for example, broadcasting video from a smartphone/tablet). The specific application of the wireless connection may be different, depending on the functionality of the TV; in addition to Internet access, examples include DLNA, receiving or transmitting video via Wi-Di or Miracast, and using a mobile gadget as a remote control. However, almost all models with this feature belong to Smart TV (see above).
As for Wi-Fi versions, the most relevant nowadays are Wi-Fi 5, Wi-Fi 6 and Wi-Fi 6E. Also note that, in addition to these Wi-Fi standards, earlier ones are usually supported — so compatibility problems does not occur.

— Miracast. TV support for Miracast technology. This technology allows you to broadcast video and audio signals via Wi-Fi technology (both to the TV and from it to portable electronics), while both devices are connected directly (Wi-Fi Direct) and do not require additional equipment, and the bandwidth is sufficient for Full HD video transmission and 5.1 multi-channel audio. Some time ago, TVs used a similar WiDi technology, but nowadays it is almost ousted from the market, and most manufacturers use Miracast.

— Chromecast. Chromecast technology allows you to quickly and easily stream video and audio from your smartphone, tablet or computer to your TV. In fact, Chromecast is a network media player, because after setting up this function, you can wirelessly display the video recorded on your smartphone on your TV with just one touch.

— Bluetooth. Bluetooth technology (any version) is used for direct wireless communication between different devices. How it is used on TVs may vary, depending on the functionality of a particular model (and version of Bluetooth). So, it is almost mandatory for Bluetooth TVs to be able to transfer sound to wireless headphones or speakers. In addition, other use cases may be provided: connecting keyboards, mice and game controllers, direct file exchange with a laptop, remote control from a smartphone or other gadget, etc. These details should be clarified separately. As for specific versions, in many models these details are not specified at all — for use for the intended purpose, “just Bluetooth” is enough. However, there are exceptions, and here the following options are relevant for modern TVs:

• Bluetooth v4.0. A version that combines traditional Bluetooth 2.1, a high-speed standard for transferring large files, and "Bluetooth Low Energy" for small amounts of information. All subsequent versions are built on these three components (with various improvements), and v 4.0 was the first where they appeared all together.
• Bluetooth v 4.1. Improvement of version 4.0, in which compatibility with mobile devices of the 4G LTE standard has been improved — so that the LTE and Bluetooth modules do not create mutual interference while working nearby.
• Bluetooth v4.2. Further development of version 4.0; updates that are relevant for TVs include mainly improving the reliability and noise immunity of communications.
• Bluetooth v5.0. One of the key improvements in version 5.0 compared to previous editions of the protocol was the presence of two special “Low Energy” modes – increased range (due to reduced speed) and increased speed (due to reduced range).
• Bluetooth v 5.1. Update of the v 5.0 version described above. In addition to general improvements in the quality and reliability of communication, this update has implemented such an interesting feature as determining the direction from which the Bluetooth signal is coming. Thanks to this, it becomes possible to determine the location of connected devices with an accuracy of up to a centimeter (for example, a remote control).
• Bluetooth v 5.2. The next, after 5.1, is the fifth-generation Bluetooth update. The main innovations in this version are a number of security improvements, additional power optimization in LE mode, and a new audio signal format for synchronized parallel playback on multiple devices.
• Bluetooth v 5.3. The Bluetooth v 5.3 wireless protocol was introduced at the beginning of 2022. Among the innovations, it accelerated the process of choosing the communication channel between the controller and the device, implemented the function of quickly switching between the state of operation in a small duty cycle and high-speed mode, improved the throughput and stability of the connection by reducing the susceptibility to interference. In case of unexpected interference in the Low Energy mode of operation, the procedure for selecting a communication channel for switching is now accelerated. There are no fundamental innovations in protocol 5.3, but a number of qualitative improvements are seen in it.

— Ambilight. Screen backlight technology. In this case, the TV case illuminates the wall/partition located at the back, due to which a blurry halo appears around the screen contour in the colour of changing scenes. This effect visually expands the screen area, making watching TV more enjoyable. There are three types of backlighting in total: classic Ambilight (on the sides only), Ambilight Surround (on the sides and top), Ambilight Full Surround (from all sides). But manufacturers continue to work on improving the backlight. So, relatively recently, the Ambilight Spectra backlight has appeared, in which the colour matching algorithm has been significantly improved and the LEDs themselves have been optimized.

— Voice control. TV support for voice control allows you to dictate certain commands through the remote control. However, not all functions are covered by voice control and recognition accuracy may require re-entering the command. If you need a more extensive range of functions, then pay attention to the voice assistant.

— Voice assistant. For a long time now, device control has been shifting to voice commands. For this, certain interfaces and systems are used. The most popular are Amazon Alexa and Google Assistant, as well as Samsung's own Bixby assistant. For "apple" devices, this is Apple Siri, but this technique is not presented on TVs. At the same time, unlike the voice control function, the voice assistant does not just turn on this or that function, mode, makes it louder, quieter, but allows you to perform certain operations in applications, whether it is to launch the desired clip in Youtube or display the weather in the browser.
