Sound power

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.

Number of speakers

The number of speakers installed in the TV.

Theoretically, one speaker is enough to work with sound, but most entry-level and mid-range models (as well as many premium devices) provide two speakers — for stereo operation, which allows to achieve some surround sound effect. And more than two speakers usually means the TV has enhanced audio capabilities such as a subwoofer or soundbar (see below).

HDMI technologies

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.

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.

Power consumption

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.

Energy efficiency class (new)

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.
