On the purchase of LCD TVs pay attention to details

To buy an LCD TV, consumers should pay special attention to small details so as not to cause trouble in the future.

Bad spots and bright spots Check whether there are bright spots on the LCD TV. The easiest way is to make the screen black, and if there are bright spots in a black spot, about 30 cm away from the LCD TV screen. Then make the screen white and see if there are any dead pixels. Then change to red (red), green (blue) and blue (blue) to check the integrity of the color point. Look at the screen at about 2.5 meters to see if the brightness of the screen is even and whether the full screen is a solid color. Do not resolutely.

The speed of changing channels can't be slow. Generally, there is no TV signal in the mall. Everyone focuses on the response speed of the TV screen and doesn't pay attention to a more terrible TV performance. That is the most common way for everyone to watch TV: changing channels. . The promoters will not take the initiative to let you try to change the speed of experience. Imagine if you need 5 seconds to switch every time, do you still have the mood to watch TV? Trying to change the speed is very necessary.

The quality of the wall-mounted racks is good for now. When buying LCD TVs, major TV brands are only equipped with bases and are not equipped with pylons. Users who need pylons can only buy pylons by selling TV salesmen or aftermarket installers. When a user buys a rack, he must first understand whether the product has passed the relevant safety regulations and environmental protection certifications such as GS/CE/UL/ROSH. Secondly, he must understand the material and the maximum weight, and finally understand the after-sales service content and the exemption clause of the manufacturer.
