Nowadays, buying a light and stylish LED TV has become the choice of many families, but various styles of LCD TVs make consumers worry, which brand of LED LCD TV is better, and how to choose a cost-effective smart HD TV?

1. Distinguish between PC screens and AV screens: LED TV screens are divided into PC screens and dedicated AV screens according to their skills and technologies. AV display is a special screen for LED TV, which has been greatly improved in image resolution, color and level.

PC screens are usually only used in notebook computers, due to their poor functionality and low price, a single manufacturer may use them to counterfeit AV screens. When consumers buy small and medium-sized LCD TVs, they can compare the brightness and contrast with other LCD TVs of different sizes and types. If the color is bright and the response speed is fast, it is an AV screen.

2. Determine the quality of image resolution: resolution is one of the important parameters of LED TV , and resolution will affect the clarity of the picture. High-resolution LCD TVs have clear and detailed images, and images have sharp edges. If the resolution is too low, the photo will be grainy and grain will be noticeable on close-ups.

The fixed resolution of LED TV is also its optimal resolution, generally, the resolution of 1024×768 or higher has the characteristics of high-definition television. Products with a resolution higher than this will be more suitable as a computer to watch high-definition TV and multimedia terminals. Currently, LED LCD TVs mainly have several common resolutions, such as 800×600, 1280×768 and 1366×768.

3. Determine the appropriate screen layout: The current LED TV screen sharing generally has two types: 4:3 and 16:9. Many 16:9 and 4:3 format TVs can adjust the display format of the picture through the menu, but it is usually not safe to see the effect of the picture through the stretching process. 4:3 ratio is suitable for imitating the current display mode of TV signal, it is mainly used for watching TV, it is recommended to choose 4:3 products.

16:9 aspect ratio is the most suitable mode for human eyes, and it is mainly used for enjoying DVDs. For blockbuster movies, 16:9 format will bring visual enjoyment, while 4:3 format will never be able to achieve. Consumers should also choose the appropriate size according to the size of the room when purchasing a machine, so as to prevent the screen from being too large and creating a sense of oppression.
