What should be paid attention to when purchasing LED TV?
1. Look at the consistency, play white and red, green and blue, without mosaics.
2. Look at the heat dissipation, and there should be no excessive heat generation.
3. Check the refresh rate for tailing and flickering.
4. Look at the contrast and black expressiveness. In fact, many LED LCD TVs have more or less disadvantages in terms of black expressiveness, while LED backlight TVs can automatically adjust the brightness level of LEDs, broaden the performance of contrast, improve the black depth, and make the black expressive more profound. The advantage of black performance has become one of the signs of a good LED TV . When purchasing, you can directly compare how well the TV expresses the black screen.
5. Look at the expressiveness of the color gamut. It can be roughly judged like this. For example, the inversion effect of a photo is richer and clearer than before the inversion. Then the TV with a small color gamut will lose color like a photo that needs an inversion effect, and the color is not in place. .
6. Look at the dynamic picture display effect. Due to the advantages of backlight, LED TV itself has an advantage over ordinary LCD in terms of response speed. It can be distinguished by providing parameter data—screen refresh rate and watching dynamic images with the naked eye. For example, you can find a shopping guide to play racing, ball games and other videos . As for the screen refresh rate, the TV screen refresh rate on the market ranges from 100Hz to 200Hz. The higher the screen refresh rate, the more stable and clear the picture performance.
7. Look at the interface. The reason why the interface is mentioned in the high-definition TV purchase strategy is because if you want to enjoy high-definition video, you have to watch the source, connect to the computer, DVD, and PS3. These external functions must be considered carefully. A few more HDMI ports will never suffer. However, when buying an LED TV , don’t let the slimness fool your eyes. In order to pursue slimness, many manufacturers use external ports. It is also very important to pay attention to choosing a TV with a complete set of built-in ports.
