There are many nuances to consider when buying a good LCD TV. In addition, it is important to check the functionality and quality of the equipment immediately before purchasing. This will save you from potential problems associated with returning the goods to the seller.

TFT-test
Instructions
Step 1
Never select a TV based solely on the size of its display. This is fundamentally the wrong approach. When viewing the LCD TV, visually must be at a distance of more than three diagonals of the display. Consider this when choosing the size of your TV matrix.
Step 2
If you are buying a TV solely to watch TV channels, do not waste your money on devices with high-definition matrix. For a widescreen display, a resolution of 1280x1024 will suffice.
Step 3
Pay attention to the response time of the TV matrix. This characteristic is important when watching movies with a fast frame rate. Modern LCD TVs must have a matrix response of less than 6ms.
Step 4
When using your TV during the day, it is best to choose a device with a high brightness rating. This will provide a comfortable viewing experience in daylight. Pay attention to the contrast of the display. In this case, we are not talking about dynamic contrast, which is achieved by using image processing algorithms, but about specific characteristics of the matrix.
Step 5
If you want a TV with a rich color gamut, choose LED displays. Their design uses LED backlighting, which has a positive effect on color rendering.
Step 6
Be sure to check the quality of the matrix when buying a TV. Pre-download the TFT-test program on a USB flash drive and take it with you to the store. Ask to connect the TV to the laptop via an HDMI cable.
Step 7
Run TFT-test. First, make sure that there are no “dead pixels”. Run monochrome pictures one by one to check the quality of the display.
Step 8
Now run the frame rate test. Be sure to check the uniformity of the distribution of the color gamut and make sure that the pixel grid is free of defects.
