No

Local Dimming

LED TVs use LED backlighting behind the screen. LED TVs with Local Dimming capability can illuminate different areas of the screen with different intensities, achieving better local black performance and contrast compared to regular LEDs.

OLED TVs do not require this technology as the lighting is integrated into each individual pixel and can be completely turned off, providing absolute black and even better contrast.

Audio

Channels
2.1

Channels

Channels refer to the number and type of individual speakers contained in the television and are described by 2 numbers separated by a dot. The first number refers to how many full-range speakers (speakers for the entire frequency range) the television contains, while the second refers to how many subwoofer-type speakers (speakers specialized for bass frequencies). For example, a television with 2.1 speakers has 2 regular speakers and 1 subwoofer.

2. Almost all television programs are stereo (for playback from at least 2 speakers), meaning they are designed to sound different in each of the 2 speakers to give the listener a sense of space. More speakers make this feeling even more realistic, and the presence of a subwoofer gives fuller bass.

2.1
The TV contains 2 speakers for stereo sound (depth sound) and 1 subwoofer for deeper bass.
Power
40 W

Power

The sum of the power of the TV speakers. Most TVs have 2 speakers of 10 watts each, which add up to 20 watts.
