news hardware 4K TV: What is the perfect reversing distance? Samsung responds!
A recurring question when buying a new 4K TV, do I have the perspective to get the most out of it? Through the recommendations of Samsung and film professionals, we are going to try to answer once and for all this existential question that has divided households for so many years.
- The higher the definition of the TV, the less important the recoil
- But by the way, what is the tone of a screen?
- What are the limits of the human field of vision?
- How far back can my HDTV go?
- Samsung recommended viewing distance for its 4K TVs
- SMPTE recommended viewing distance
The higher the definition of the TV, the less important the recoil
Ever since televisions have been invited into our living rooms, a generational debate between young and old has constantly arisen at family meals about the necessary distance to a screen. The main argument of “You’re too close, you’ll hurt your eyes” is true, but totally obsolete in the age of 4K Ultra High Definition (UHD) displays.
In the era of cathode ray televisions, from 1935 to the early 2000s, long before 8K (4230p), 4K (2160p), Full HD (1080p) or the famous HD Ready (720p), we had to settle for a very low definition image format, often less than 480p.
But by the way, what is the tone of a screen?
Specifically, the pitch designates the space between two pixels on a screen, whether on televisions, computers or smartphones, we are talking about the same thing. Therefore, the larger the number of pixels, the smaller the space between two pixels. So the lower the pitch, the better the potential image quality: even when we get closer to the screen, we no longer see the pixels.
This is how with current screens, of the Full HD or 4K type, we can more easily discern the ready image, while in the time of our grandparents, lower resolutions naturally brought an important higher tone and forced us to move away from the screen. to see the images correctly without seeing the pixels.
However, there are very important launches on advertising screens, for example, that are intended to be seen from afar.
This is how the famous “3x rule” was established, where it was said in broad strokes that you had to multiply the size of the diagonal of the television by 3 to have the necessary distance to make the most of your screen. At the end of the cathodic era, televisions measured between 55 cm and 82 cm diagonally (we were not talking about inches then) and weighed more than 50 kg… Therefore, it was necessary to go back at least 2.5 m for a television 82 cm or 32 inches. Fortunately HD has arrived and now 4K and everything has changed!
What are the limits of the human field of vision?
Imagine if this 3x rule was still valid today? For a 65-inch screen (about 165 cm) almost 5 meters of setback would be needed and more than 6 meters for an 85-inch one. Inconceivable. Fortunately, with the quality of today’s screens, you can enjoy high-definition content at a much more acceptable distance than was previously necessary.
To better understand the data that follows, a diagram is worth a thousand words:
Basically, we distinguish a difference between what we see (the famous 120° binocular vision) but also and above all with what we perceive, such as colors and symbols that require a much more restricted field of action.
How far back can my HDTV go?
Starting from this premise, Samsung, for example, recommends a 40° field of view for its 4K displays, which equates to a viewing distance equal to 1.2 times the screen size.which gives the following results.
Samsung recommended viewing distance for its 4K TVs
|Screen size (in inches)||Appropriate reversing distance|
by his side, the SMPTE (Society of Motion Picture & Television Engineers) distinguishes between two types of use, depending on whether you watch sports and current affairs programs (JT, TV shows, news) or if you watch movies, series or play video games. For the first use, the SMPTE recommends a field of vision of 30° and for the second, 40°, like Samsung.
SMPTE recommended viewing distance
|Screen size (in inches)||Reversing distance suitable for movies (30° viewing angle)||Reversing distance suitable for gaming (40° viewing angle)|
|24″||0.96 to 1.02 meters||0.72 to 0.84 meters|
|32″||1.28 to 1.36 meters||0.96 to 1.12 meters|
|43″||1.73 to 1.84 meters||1.30 to 1.51 meters|
|fifty”||2.03 to 2.15 meters||1.52 to 1.78 meters|
|55″||2.22 to 2.36 meters||1.67 to 1.95 meters|
|Sixty-five”||2.62 to 2.79 meters||1.97 to 2.30 meters|
|75″||3.02 to 3.21 meters||2.27 to 2.65 meters|
|82″||3.33 to 3.54 meters||2.49 to 2.91 meters|
|85″||3.42 to 3.64 meters||2.57 to 3.0 meters|
Too often we hear people say that 65-inch televisions are too big for their living room and that they will never have the necessary perspective. While in reality you only need 1.96 m of distance to ideally enjoy your 4K TV and only 2.27 m for a 75-inch TV.. Now dare with the big TVs!
In any case, keep in mind that these values are purely indicative and that the most important thing is your personal feelings. There is only one right choice, yours!
