Wondering how to pick a good LCD TV and get it right? Pay attention to 5 important parameters that determine the quality of the picture and sound.
Selecting an LCD (LED) TV
1. Screen resolution
The image quality depends on the screen resolution when watching TV channels with HD resolution, as well as Blu-ray and DVD. The higher the screen resolution, the clearer the image on the screen, even during dynamic scenes. It is expressed in two numbers. The first determines the number of pixels horizontally, the second vertically:
- 1024 x 768 - less popular among users,
- 1366 x 768 - the highest quality picture when watching movies from a DVD player,
- 1920 x 1080 - optimal for digital television,
- 3840 x 2160.
4K Ultra HD delivers 4x deeper detail and clarity than Full HD screens. Televisions with this feature and a user-friendly interface have a Smart TV function and a built-in multi-channel speaker system. Thanks to it, you can truly experience the powerful sound of a movie theater.
2. Response time of the matrix
The response time of the matrix determines the period of conversion of pixels (liquid crystals) into a certain color gamut of the picture with a change in the image on the screen. Measured in milliseconds. The shorter this time, the better the active actions in movies or games are reproduced. For example, 8-10 ms is enough to watch programs. For games, choose the TVs with the lowest rating. In OLED TV, the minimum response time is 0.002 ms, so the spec. the effects are much more expressive than LED TVs.
3. SMART TV
Thanks to the intuitive Smart TV, you can easily connect to content from different providers. With the Web Os interface, setting up your TV for quick access to applications just got easier. The device remembers which application you stopped on the last time when selecting the latest new products.
3D support in LED TVs creates a new dimension of reality when watching regular video.
Virtual Surround Plus delivers impressive surround sound from all angles.
Thanks to the smart power saving function, it is convenient to adjust the brightness of the backlight.
4. Sound
Inexpensive models of LED (ice) TVs have only 1-2 speakers built in, which reproduce not clear sound. Advanced models are equipped with a stereo system with 2-8 speakers (depending on the model) with a wide sound range. Sound from the front speakers instantly fills the space as it spreads out in multiple directions, creating 3D audio.

5. Viewing angle
Due to the change in the movement of the pixels (parallel to each other, and not spiral, as before) one of the main advantages of IPS matrices has appeared - an increase in the viewing angle up to 178 degrees horizontally and vertically, in contrast to the TN matrix. Therefore, the broadcasting picture on the TV is always clear and bright, without color distortion. However, with inexpensive TVs, the picture on the TV screen is distorted depending on where you are in relation to the screen. This is because the permissible vertical viewing angle is 160 degrees, and the horizontal viewing angle is 170.
