Now the price is almost the same. Should I buy a 4K TV?

I have seen Konka's model before, but it only supports 4K, and there is no real 2K to 4K technology. You can look at Skyworth's new 4K products 790U and Changhong B6000ID, both of which belong to real 4K TVs. You can Baidu about the purchase standard of 4K TV. Finally, I bought Changhong, and the response speed was very fast. According to the shopping guide, Changhong has low advertising cost and high cost performance. I compared it myself, and both of them are new products. Skyworth is really more expensive. Of course, it's up to you to decide which one to buy in the end. As for the shortcomings of 4k, I think the film source is too small, which is a bit like killing a chicken with a knife, but the price is not much expensive. You should know the advantages of 4K yourself.
