— 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.

– 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 highest frame rate supported by the TV.

Note that in this case we are talking specifically about the screen’s own frame rate, without additional image processing (see “Index of dynamic scenes”). This frequency must be no lower than the frame rate in the video being played - otherwise there may be jerks, interference and other unpleasant phenomena that degrade the quality of the picture. In addition, the higher the frame rate, the smoother and smoother the movement in the frame will look, and the better the detail of moving objects will be. However, it is worth noting here that playback speed is often limited by the properties of the content, and not by the characteristics of the screen. For example, films are often recorded at a frequency of only 30 fps, or even 24 - 25 fps, while most modern TVs support frequencies of 50 or 60 Hz. This is enough even for viewing high-quality content in HD resolutions (speeds above 60 fps in such video are extremely rare), but there are also “faster” screens on the market: 100 Hz, 120 Hz and 144 Hz. Such speeds, as a rule, indicate a fairly high class of the screen; they also often imply the use of various technologies designed to improve the quality of dynamic scenes.

TV compatibility with special frame synchronization technologies used in AMD graphics cards.

You should pay attention to this parameter if you plan to use the TV as a gaming monitor for a PC or laptop with an AMD graphics adapter. Special timing technologies are used to match the screen refresh rate to the frame rate of the incoming video signal. Such a need arises for the reason that the frame rate issued by the graphics card can “float” when the load on the video adapter changes (this is especially true for demanding games); and if this frequency does not match the screen refresh rate – tears and other unwanted artifacts appear on the image.

The AMD technology used to eliminate this effect is called FreeSync. Nowadays, it is presented on the market in three versions — the original FreeSync and two extended ones:

– AMD FreeSync Premium Pro. The most advanced and functional version, formerly known as AMD FreeSync 2 HDR. In addition to refresh rate sync, it also includes support for HDR (see above), output at a frame rate of at least 120 Hz at Full HD resolution, as well as low frame rate compensation (LFC). The essence of LFC is that when the frame rate of the original video signal falls below the minimum frequency supported by the screen, the same frame is displayed on the screen several times, which allows to maintain the maximum smoothness of the “picture”.

— AMD FreeSync Premium. A somewhat s...implified version compared to FreeSync Premium Pro. It does not provide working with HDR, otherwise it is completely similar.

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.

The number of HDMI inputs provided in the design of the TV.

HDMI is a comprehensive digital interface that allows high-definition video and multi-channel audio to be transmitted over a single cable. It is widely used in modern HD equipment — in fact, the presence of such an output is mandatory for modern media centers, DVD players, etc. Therefore, LCD TVs in the vast majority of cases are equipped with at least one HDMI port. And the presence of several such ports allows you to simultaneously connect several signal sources and switch between them; in some models, the number of HDMI can reach 4 or even more. At the same time, some manufacturers use technologies that allow you to control devices connected to the TV via HDMI from a single remote control.

About the interface itself, see above, and its different versions differ in maximum resolution and other features. Here are the options found in modern TVs:

— v 1.4. The oldest of the current versions, released in 2009. However, it supports 3D video, capable of working with resolutions up to 4096x2160 at 24 fps, and in Full HD resolution, the frame rate can reach 120 fps. In addition to the original v.1.4, there are also improved modifications — v.1.4a and v.1.4b; they are similar in terms of basic features, in both cases the improvements affected mainly work with 3D content.

– v 2.0. Significant update to HDMI introduced in 2013. In this version, the maximum frame rate in 4K has increased to 60 fps, and the audio bandwidth has increased to 32 channels and 4 separate streams simultaneously. Also from the innovations, we can mention support for the ultra-wide format 21:9. In the v.2.0a update HDR support was added to the interface capabilities, in v.2.0b this feature was improved and expanded.

— v 2.1. Despite the similarity in name to v.2.0, this version, released in 2017, was a very large-scale update. In particular, it added support for 8K and even 10K at speeds up to 120 fps, as well as even more expanded features for working with HDR. Under this version, its own cable was released — HDMI Ultra High Speed, all HDMI 2.1 features are available only when using cables of this standard, although basic functio...ns can be used with simpler cords.

— VRR. VRR (Variable Refresh Rate) adaptive frame rate synchronization technology allows you to adjust the refresh rate of the image on the TV screen in real time in accordance with the frame rate output by the game console or connected computer. The function ensures smooth rendering of dynamic scenes, eliminates frame breaks, and guarantees comfortable and stable gameplay. Realizable technology with standard HDMI v 2.1.

— ALLM. Automatic low latency mode for games (Auto Low Latency Mode). The TV switches to game mode when it detects a game console connection. Reducing the output delay on the TV panel screen is provided by suspending part of the image processing functions. The ALLM mode can also be useful for karaoke and video calls.

eARC. HDMI v 2.1 has an enhanced eARC (enhanced Audio Return Channel). The technology allows you to send higher quality audio from your TV to your soundbar or AV receiver. It claims to support the latest high bit rate audio formats up to 192 kHz, uncompressed 5.1 and 7.1, and 32-channel uncompressed audio. eARC also supports Dolby TrueHD, DTS-HD Master Audio, DTS:X, Dolby Atmos.

— CEC. The CEC (Consumer Electronics Control) system is designed for remote control of equipment connected to the TV using a single remote control. The devices are connected to the TV panel using an HDMI cable.

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.
