Smart TV, 3D, Ultra HD, Curved displays and other terms complicate the TV selection process, so naturally when faced with the question, how to choose the model that best suits your needs? What parameters need to be kept in mind and which ones can be omitted? home appliances experts advise you on how to choose a TV.


The size of the TV screen

To get the most out of your TV viewing experience, first and foremost, you need to find an ideal point for the TV screen diagonal to screen ratio.

When choosing a TV screen size, the "bigger, better" principle is not always correct. Sure, a large TV will give you a cinema-like atmosphere at home, but 46-52 inches. a diagonal model in a small room of 10-12 m2 will not be a smart solution. According to TV experts at, the distance to look at the screen must be taken into account in order to properly select the size of the TV. 32 inches it is recommended to watch a diagonal screen TV from a distance of at least 1.25 m. 55 inches devices should be at least 2 meters from the viewer. The maximum comfortable viewing distance of a TV is usually twice the minimum recommended distance.


TV picture quality - TV resolution

There are currently 3 standart definition TVs available on the market.

4K UHD (3840 x 2160 px.)

4K is a standard for screen resolutions that is characterized by two sizes: 4096 x 3112 (4: 3 panoramic aspect ratio) and 3840x2160 pixels. TV experts note that in order to truly enjoy the full 4K quality, you should watch the content of the 4K standard.

Full HD (1920 x 1080 px.)

Full HD is now the standard for mid-range TVs. A wide range of movies and the availability of digital TV channels allow you to take full advantage of Full HD TV.

HD Ready (1280 x 720 px.)

The standard for this resolution is found in budget TV models.

The type of TV screen

Three main types of TV screen matrices can be distinguished. 


LCD technology with LED backlit TVs are currently the cheapest and most widespread type of screen. TVs with LCD / LED displays have a brighter black color, less contrast, some degree of color distortion and other imperfections. The supply of LCD / LED TVs is very high. Manufacturers offer both very small and large diagonal LED TVs, which also vary greatly in price.


OLED TVs (with panel using self-emitting diodes) are a guarantee of perfect black color, great contrast and accurate color rendering regardless of the viewing angle. True, these benefits are still quite expensive. It should be noted that OLED TVs are only available in high definition (55 inches and higher).

QLED TVs (Quantum Dot)

The QLED TV is actually an LCD model with (at least in theory) better colors provided by the so-called Quantum Dot layer. Despite its name, it is technically and practically a closer model to an LCD than an OLED TV.

TV refresh rates

According to TV specialists, another very important parameter when choosing a TV is the refresh rate, measured in hertz (Hz). In theory, the higher the refresh rate, the better the quality of the image. For example, a 100 Hz TV refresh rate refers to the ability of the screen to display up to 100 frames per second. image. Is this value enough? According to experts at, today it is already the standard that allows you to watch TV comfortably, but it is worth noting that there are TVs available in the market with refresh rates of 200, 300 and even 600 Hz.

Fake refresh rate conversions: Samsung Clear Motion Rate vs. Samsung Clear Motion Rate Sony refresh rate (Sony MotionFlow) vs. LG Frequency of Motion (LG Motion Clarity Index)

Each individual TV manufacturer has compiled its own refresh rate numbers, thus providing a non-realistic TV refresh rate setting. For Samsung it is Clear Motion Rate (CMR), Sony for MotionFlow, LG for TruMotion or Motion Clarity Index, Vizio for SPS , Toshiba - ClearScan, Panasonic - Backlight Scan. The table below shows the actual refresh rate indices that correspond to the parameters provided by different manufacturers.

This situation is misleading for users, as manufacturers include their personal number in their device specifications instead of specifying the actual refresh rate. Such inflated numbers make it difficult to make a representative comparison between different brands of TVs..

Samsung Clear Motion Rate (Samsung Clear Motion Rate)

Samsung's Clear Motion Rate does not match the actual refresh rate of the screen. This manufacturer has deceptively increased this number by adding to it the backlight frequency and processor speed. The table below shows that these figures are sufficiently different.

Magnification from 240 to 480 CMR is irrelevant as it is the same actual refresh rate of 120 Hz. The 720, 840, and 960 have clear movement frequencies that have the same real refresh rate of 240 Hz, so you won't notice any difference between them in the context of resolution motion.

Sony refresh rate (Sony MotionFlow)

Similar to Samsung, Sony also inflates the refresh rates of its TVs using the MotionFlow nomenclature. However, as shown in the table, they are more stable in the case of Sony. MotionFlow is the name the company uses to create its own "bubble" effect in the context of the parameters.

LG Frequency (LG TruMotion and Motion Clarity Index)

In 2014, LG changed its nomenclature to bring the refresh rate parameter in line with the index used in countries outside the US. In the past, the TruMotion Index was used in the US and the Motion Clarity Index in other parts of the world. The Motion Clarity Index (MCI) is now used everywhere. TruMotion is a bubble effect indicator for LG's refresh rates.

„Toshiba“ „ClearScan“

Toshiba also has its own frame rate nomenclature, but unlike Samsung and LG, the numbers are more controlled. ClearScan 60 or 120 Hz represents a refresh rate of 60 Hz, while 240 Hz ClearScan corresponds to 120 Hz.

„Vizio“ company refresh rates „Effective Refresh Rate“ (SPS) and „Clear Action“

Vizio uses several nomenclatures. Smooth Motion implies the feature of motion interpolation / bubble effect. Clear Action is simply a marketing trick to compete with Samsung's Clear Motion Rate (in this context they are simply trying to have the highest number possible). Effective refresh rate Effective refresh rate is the refresh rate + the backlight frequency.

Wide dynamic range HDR

More than refreshing technology is important for a high quality image. According to TV experts at, the wide color palette and the High Dynamic Range (HDR) are also important. The HDR-enabled display allows you to obtain a high-tonal image. Such an image is more realistic and has a higher level of detail.

3D technology

There are three main types of 3D technology available in the market: passive, active and autostereoscopy. Each technology allows you to watch 3D movies, but only the first two are generally available. What's the difference?

When 3D technology only settled on TVs, it was thought to be a revolution in movie watching, but we know that it wasn't very popular and the producers are no longer developing it. Most TV manufacturers have decided to work on video rendering quality and replace 3D with something new. Of course, many manufacturers still offer 3D models of TVs.

Curved TVs

Curved display has emerged on TVs with the spread of OLED technology. The curvature of the screen means that each image format is equally distant from our eyes. With this solution we can have the impression that the excerpts displayed are the same size when they are in the center and at the edges of the screen. The curved screen is better adapted to the natural field of view of the human being, which gives the impression of being surrounded by films. According to TV experts at, the main disadvantage of curved displays is the need to sit exactly in front of the TV so that the gaze falls to the center point of the screen.

SMART TV – what is it and why we need it?

The Smart TV technology turns the TV into a multimedia entertainment center under the responsibility of the Android system or its proprietary system (eg LG webOS, Samsung SmartHub Tizen, Panasonic FireFox OS). personalize your device and control your TV with your phone or tablet.

The Smart TV feature may have different names depending on the TV manufacturer.

What other features does Smart TV offer?

What's more, one of the more exciting features of Smart TV is the ability to control the TV with gestures. Depending on the manufacturer, this feature can be implemented with the Magic Remote. This makes it easy to switch channels, increase and decrease volume, and access other TV features. Smart TV?

The ability to control the TV with simple voice commands (English only). This mode of control makes it easy to use most TV functions.

The TV software also allows you to personalize the content being displayed by adjusting the thematic range of the programs you want to watch with face recognition.

Skype TV app allows you to perform video conferencing and video chat (with or without an integrated webcam or accessory) with colleagues and friends, whether using a computer or a TV.
