This is just one of many versions but there are two comparison tables with very large distances. Why? The reason is that Table 1 is for 480P or 576P DVD picture quality source, cable TV non-HD signal, and Table 2 is for Blu-ray disc or 1080P Full HD signal, and the current domestic cable TV HD channel signal can also be similar to 1080P The signal can be slightly further away from the reference point.
Even if the above two LCD TVs recommended viewing distance table with the rapid advancement of technology are actually somewhat out of date, that time is still the highest 1080P resolution, the maximum size of 65 å‹ only, in recent years, domestic 4K TV has become a popular trend, the maximum size of 120å‹ Even higher, 8K TVs, 200-inch TVs have already appeared, and 4K video is not only used to test decoding capabilities and demos in the early years. With the mature conditions of the H.265 compression technology 4K source network transmission, then Buy a 4K TV now. Consider the perfect 4K video source in the future. What is the new recommended viewing distance?
Here we must first talk about what is the recommended viewing distance, first of all because now LCD TVs are basically 16:9, and human eye structure restrictions, we have a range of perspectives, recommended viewing distance to ensure that horizontal and vertical viewing angles can cover TV screen:
Through this range of perspective, it can be calculated that the suitable TV size under the sight distance of 3 meters is less than 85 feet, that is to say, the 3 meters line-of-sight distance (most of the family living room TV sight distance is between 2.5 meters and 3.5 meters) exceeds 85 feet. TV viewers will not be able to see the full range of perspectives (Yu Guang naturally cannot see things clearly). However, 40-85 TVs have many specifications. Because of the panel source and cost considerations, a large number of manufacturers have pushed 55 baht before, and even printed on the leaflets to promote home living room 55 baht is the best size, in fact, all sales The size of the main force only, in fact 4K resolution in the end of the 3 meters line of sight what size is the most appropriate?
Let's first look at the picture below:
Can't seem to see any obvious difference? This is the difference between playing 4K and 1080P video sources on a 50-inch 4K TV 3 meters viewing distance, because the distance is large and the screen is small. Even if the resolution is enough, it is not enough to see the details, leading to the fact that 1080P TV and 4K TV broadcast 1080P source. Still, the visual difference between 4K sources is almost undetectable.
Then look at the following picture:
It can be clearly seen that as the viewing distance reaches within 1.5 meters, the difference between 4K and 1080P sources on the 4K TV starts very clearly. Because of the lack of resolution and the non-point-to-point playback in 4K TVs, 1080P must be blurred.
50 å‹ 4K TV 4K film source to see the best viewing distance of less than 1.5 meters, we can not sit in the middle of the living room to watch TV, right? 55 is also not much difference, in fact, even if the 1080P source 55 å‹ for the 3 meters line of sight is still small. Here are some authoritative suggestions:
Video and audio certification company THX has released a formula for the distance between 1080P HD TVs. Divide the TV size by 0.84 (eg 50-inch TV, 50/0.84 = 59.5 inches, about 1.5 meters)
The best viewing distance of the 4K TV provided by the television giant Sony is 1.5 times the TV height, which is equivalent to half of the suggested 1080P viewing distance, that is, roughly 1 meter is the critical value of the 50-inch 4K TV resolution.
A European and American commonly used display device viewing distance formula: the best viewing distance (unit: cm) = screen height ÷ vertical resolution × 3400, the introduction of 50-inch screen height 62cm and 4K vertical resolution 2160 can be 97.59cm is also about 1 meter.
HDTV (1080P) corresponding size distance table given by WiKi-Optimum:
The 20-100 inch, DVD to 4K quality range matching full table given by Rtings.com, a worldwide professional TV evaluation and review website:
In summary, the 50-inch 1080P best viewing distance is actually about 1.5 meters, while the 50-inch 4K best viewing distance is about 1 meter; and in reality we can't watch TV so close, so the 4K TV can be in the general living room If there is more than 3 meters of sight distance, you can choose according to the principle that the bigger the 85 degrees, the better.
Taking into account the current 4K video is not yet popular, mainly for the best line of sight of 1080P film source both the 4K TV interpolation display and the popularity of the future 4K video resources to specific recommendations:
Small size, sight distance of about 1.5 meters, 4K TV 50 inches
Mid-sized apartment, 2.5-3.5 meters in viewing distance, 4K TV 65-85 inches
Large-sized apartment, luxury home, sight distance of more than 4 meters, 85 feet to start, economic ability to allow 100-120 feet or higher.
Bedroom TV If you often see 1080P source or even 4K video, then in fact about 2 meters long bed plus aisle, generally home sight distance is also about 2 meters 5 or even farther, 4K large-screen TV popularity, the bedroom hangs 40-50 TV has also been OUT, and conditions can also be considered directly in place on the wall 60 or 65-inch 4K TV.
If you are a general apartment with 3-4 meters of viewing distance in the living room, 2.5 meters viewing distance in the bedroom, then the living room to buy 70 å‹ 4K TV, bedroom purchase 60 å‹ 4K TV is a good big-screen solution, double 11 during the flagship Shop unprecedented event 13,999 yuan to buy Sharp's latest split 70 å‹ 10 generation line wide color gamut screen TV to send the same paragraph 60 å‹ TV activity is very good value, recommend it.
