What is the reason why the images displayed on the TV at home are so different from those at the supermarket

Surely you have not less than 1 time wondering why when you go to buy a TV at the electronics supermarket, the picture looks so beautiful, but when you take it home, it is not like that? Is it possible for the supermarket to deliver the wrong goods to me? ... a lot of questions are asked in this case. In fact to get the best quality image for us to see at supermarkets, many different factors are needed such as:

1. Quality of source

The videos and advertisements you often see at the supermarket are provided by TV manufacturers, they have processed the entire video, invested carefully in post-production to get the perfect quality, highest resolution. Usually, the videos that the manufacturer provides will have a resolution at least equal to the maximum resolution of the TV, even some videos have a much larger resolution.

Source quality

When it comes to this section, many users will have the thought that the manufacturer has deceived the customer, but no, they are not at all deceiving but they bring out the best possibilities from their product to the user. . The pictures you watch at home are not as sharp as in the supermarket because the video supply is not good, the resolution is much lower than the ability of today's TV, TV program or game show. The resolution is also only at Full HD, very rare content up to 4K, so if a movie is shown in high quality, the sharp images will be shown on your TV screen. .

Because the current programs are only in HD, or Full HD, the displayed images are not as beautiful as in supermarkets.

2. The quality of the cable connected

However, when buying HDMI cables we also need to note because these cables now have up to 5 different versions with many prices, with up to 1 million VND (usually version 2.0). So when buying, we should choose the latest version and the best price that we can spend to use, which is version 2.0, with this version 2.0 your TV is capable of transmitting pictures, videos. with quality up to 4K and 60 frames / sec and this is also the cable that supermarkets often use to promote TV products.

Use an HDMI cable instead

And yet on your TV there is still another port for data connection that is a USB port, but USB will also have 2 types of business on the market today: 2.0 or 3.0. And of course with version 3.0, the quality will be much superior. If you have a 4K video feed, but you do not want to spend too much money to buy an HDMI cable, you can completely download the content to your computer, then copy it to a USB and attach it. TV to enjoy. At this time, the quality of the video you watch will be extremely sharp without spending too much money.
