Often times the placement of the television in the living room depends more on the space available than on other considerations. However, even with these restrictions, it is convenient to know what is the ideal location of the device . That will depend on its characteristics, especially its dimensions and the resolution of the screen . It is also advisable to take these same issues into account when buying a new one depending on the needs of the home. With regard to resolution, the rule is that the higher the resolution, the viewing distance is reduced . The images will contain more pixels, and therefore it does not matter that the viewers are sitting nearby, because they will not perceive them.
Another factor to consider is the size of the screen. The larger it is, the farther away it will have to be placed to contemplate it properly. The screens of 4K or ultra-high-definition (UHD) televisions offer very detailed and high-resolution images. For an aspect ratio of 16: 9 (wide) are capable of displaying images of 3840 by 2160 pixels , four times a television Full HD , who stays at 1,920 by 1,080 pixels. Current imaging technologies allow the consumer to sit very close to the screen, even with very large diagonals. That increases the feeling of immersionof the spectators. Some manufacturers have 4K televisions on the market with diagonals that exceed 100 inches.
On the other hand, you also need to weigh the viewing angle . It is best that the screen runs parallel to the eyes of the viewer, so that no more than 40 degrees angle to the left or right , and up to 15 degrees towards up or down .
Various Internet forums publish graphics on the optimal viewing distance based on the size and resolution of the television, such as the AV Forum shown here. For a 4K television with a 50-inch screen, the ideal would be to be seated at a distance of between one and two meters, approximately. For the same size, but for a Full HD screen , viewers should be a little further away; they should be placed between two and three meters apart. A giant 100-inch 4K television could be viewed from 1.8 meters to almost 4 meters, which would be the minimum distance to be able to see a Full HD television of the same inches well.
Some manufacturers recommend large screens, because they fill more field of view, reducing the contrast between the brightness of the TV and the darkness of the room. With this, visual fatigue could be reduced , especially in those houses where the television is seen with almost no ambient light. Another trick is to reduce the brightness level of the TV during night viewing sessions, to make the viewing experience more comfortable for the eyes.
