I often encounter such problems, 42-inch full-HDTV is how much, 55-inch 4K ultra-high-definition television is a few centimeters, buy high-definition television, how much the size of the right size, suitable for viewing distance and so on. In the past few days we have come to solve the problems related to 4K, full HD TV screen size and viewing distance.
Buying a 4K, Full HD TV is very simple but also very complicated. Why is it so simple? We don't mention it today. We mainly talk about why it's complicated. In fact, it has a big relationship with the size of the TV. What's wrong with that?
Since we know the concept of Full HD and 4K TV, compared to everyone's quality of high definition TV has a very high quality pursuit, then we have to ask, how large size high-definition TV can be perfectly rendered the fine quality of it ? The answer is: Full HD TV is 42 inches, 4K Ultra HD TV is 55 inches.
This size is not Hu's, it is theoretically based, it involves another concept - perspective. When the size of the TV is larger, we think that the user's viewing angle is larger, but it does not mean that the quality of the image is higher. For example, in the same Full HD movie, the picture may be very clear on a Full HD TV, but on a larger 4K TV, the picture is barely acceptable. This concept is more difficult to understand below explained with two sets of pictures.
First group:
Which picture above is better? I think it is the first pair. It is verified that the larger the size of the television, the larger the user's perspective and the higher the quality of the image.
Second Group:
Can you see which picture is more detailed in this picture? At the prompt, the large picture frame is 1080P (full HD picture), and the small picture frame is 2160P (4K picture). Since the picture is too small to be seen, it may not be very clear. Through the contrast of colors, it can be concluded that the colors in the smaller frame are more vivid and moving.
4K, Full HD TV Screen Size List
Before you look at the 4K, Full HD TV screen size list, you first need to know what we usually mean by screen size. It refers to the distance between the diagonals of the screen. Let's take a look at the size of a common HDTV. In order to make it easier for users to determine how large a TV set is needed based on the available data (screen size), the corresponding screen size is expressed in terms of screen width (cm) and screen height (cm). I hope everyone likes (according to 16:) 9 contrast calculation).
Screen size (inch) Screen width (cm) Screen height (cm)
32 69.7 39.2
39 86.3 48.5
40 88.5 49.8
42 93.0 52.3
46 101.9 57.3
47 106.2 58.6
48 104.0 58.5
49 108.4 61.1
50 110.7 62.2
52 115.0 64.7
55 121.7 68.1
58 128.3 89.0
If your HDTV is not in the above size, calculate it as 1 inch = 2.54cm.
