— 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.

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.

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.

The TV's support of one or the other colour enhancement technology.

Such technologies usually involve image processing in software to provide brighter and/or more accurate colours. Specific processing methods may be different, some manufacturers do not specify technical details at all, limiting themselves to advertising statements. The effect of using such technologies can also vary: in some cases it is clearly visible, in others it is almost absent, depending on the features of the picture. It is also worth saying that this feature, usually, needs to be turned on manually in the TV menu (accordingly, it can be turned off if desired).

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.

Most TVs have a VESA wall mount which may vary in size. The basis for such mount is a rectangular plate with four holes for screws in the corners. The main characteristic of such a mount is the distance between the holes — it is measured along the sides of the rectangle and is expressed in two numbers. The original VESA format is 100x100, these mounts are used for most medium-sized LCD TVs. For small screens, 75x75 mounts are provided, for large ones — 200x200 and more (up to 800x400).

However, there are also models that are equipped with a standard (proprietary) mount from the manufacturer. Mostly these are either ultra-thin TVs or designer lines. Anyway, the mount in the kit is suitable only for the selected model.

— 2 separate legs. Two legs as support are usually located on different sides of the lower face of the TV panel body. Such a design involves placing the TV on a large flat surface that extends along the entire lower side of the device. The TV is often more stable on two "legs" than on one leg.

— 1 leg on the platform. A support for the TV with a round or rectangular platform, which is in contact with the surface of the TV panel (table, stand, etc.) with its entire plane.

— 1 leg with supports. Stands of this kind consist of a single leg and a base of various geometric shapes that holds the TV. This solution ensures reliable stability of the TV panel, and in terms of design, it is a stylish element of the design of the structure.

— Monolithic. A solid stand with two or more attachment points to the bottom of the TV and monolithic frames as a solid support for installing the TV panel on a flat surface of a table or stand.

The electrical power normally consumed by the TV. This parameter strongly depends on the screen size and sound power (see above), however, it can be determined by other parameters — primarily additional features and technologies implemented in the design. It is worth noting that most modern LCD TVs are quite economical, and most often this parameter does not play a significant role — in most cases, power consumption is about several tens of watts. And even large models with a diagonal of 70 – 90" consume about 200 – 300 W — this can be compared with the system unit of a low-power desktop PC.

This parameter characterizes the efficiency of electricity consumption. Classes are designated in Latin letters from A to G, in ascending order of energy consumption. Actually, this was originally conceived, until more energy-efficient models pulled up to class A, which eventually received the marking A +, A ++, A +++. Further development of technology has made it possible to go even further, and in order not to produce pluses in energy efficiency labeling, in March 2021, manufacturers returned to the previous indices from G to A, where A is the most energy efficient TV. Accordingly, the 2021 models will have modern markings, while older models will be marked in the same way. Accordingly, now energy efficiency G, F, E has become the most popular, and models with energy efficiency A, D, C are rare.
