Local Dimming
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
Stereo

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.

Stereo
Most televisions have stereo speakers, meaning they contain 2 speakers for stereo sound (sound with depth).
Power
16 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.

The TV speakers are sufficient for basic use, but for an improved experience, it is recommended to use a Soundbar or a Home Cinema system.

    I bought it today, and so far what I have seen is very impressive. The menu is like almost all TVs with many apps and the Play Store inside. It has the common apps installed, and I also wanted Twitch, which I found on the Play Store, downloaded it, and it works fine!! In general, for its price, it has many positives, such as the picture and the sound, which are very good!! I had seen comments that they have a strange menu and you can't manage it with the remote control, like it doesn't have apps and is cumbersome. It may be true for older models, but this particular one is as I described above!! Also, comments mention that it only has 2 holes for a stand, while it actually has 4!!
