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.

– 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.Backlight type
—
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.HDR support
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+.IMAX Enhanced
The
IMAX Enhanced Seal of Conformity is awarded to televisions that meet the video device certification requirements of IMAX Corporation. It applies to streaming and Blu-Ray content shot with IMAX cameras or processed using special DMR (Digital Media Remastering) software. To qualify for IMAX Enhanced certification, your TV must have 4K resolution, 10-bit color, support HDR10 and HDR10+, and DTS:X audio. As a result, viewers get the opportunity to enjoy the immersive effect of an IMAX cinema at home.
Brightness / contrast enhancement
TV support for one or another
brightness / contrast enhancement technology.
Usually, in this case, software image processing is implied, in such a way as to improve brightness and/or contrast (if necessary). Specific processing methods may be different — in particular, in some cases we are actually talking about turning standard content into HDR (see above), and some manufacturers do not specify technical details at all. The effectiveness of different technologies can also be different, and besides, it is highly dependent on the specific content: in some cases, the improvement will be obvious, in others it may be almost imperceptible. Also note that this feature is not always useful, so in most models it is turned off.
Built-in memory
The amount of memory installed in the TV to store content in the device. The larger size is especially relevant given that modern TVs allow the installation of additional applications that enhance the capabilities — and these applications also require space. However, do not forget that the TV system also requires space. And manufacturers by the volume can indicate both the total value and the free memory calculated for installing applications. And the volume itself can vary from
4 GB to
16 GB or more. However, a
TV with 8 GB memory may be the best option.
Wall mount
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.
