While picture quality and design are the two elements mentioned most often by people buying televisions, there is one other important criterion: the screen size. Indeed, it's not as simple as that to find out which diagonal you need. Between inches, centimetres and metres, you need to interpret the size and above all ask yourself how far you need to stand back in relation to the location you have chosen.
The first question to ask yourself is where are you going to put your television. To get the best immersion, the people watching it need to be sitting in front of it. TCL televisions have very wide viewing angles; the picture does not deteriorate if viewers are not sitting facing them. And yet, you feel like you are more immersed if you are sitting in the middle. If the living room's layout doesn't enable the screen to be placed facing the viewers, the axis may be corrected by turning the television on its stand or by placing it on a corner unit. One other criterion is the height. Ideally, the centre of the screen should be at the viewer's eye level, or else within an angle of no more than 35 degrees between the eyes and the top of the picture. Buying a TV unit according to the size of the screen you buy is often a very good solution. It's best to make sure that the screen isn't hit by any direct sunlight at the location you choose. You can always compensate with the brightness and TCL televisions are generally anti-glare treated, but it will be much more pleasant to look at the screen. You can also close your curtains to darken the room when you're watching a film. Once you've found the ideal distance, you need to choose the size, which is defined by the distance between the viewer and the television, but not only that...
The screen's technology has a huge role to play, especially its resolution.
When you choose an Ultra HD model, the definition is four times higher than Full HD. This producer a much finer picture, which you can move closer towards without any loss of result, in particular by seeing the dots which make up the picture. If you want to watch more than just your evening news and love films, TV series and sports events or video games, we strongly recommend that you choose Ultra HD for more closeness. You will be much more immersed and get a much better experience.
With the arrival of LED backlit LCD televisions, forget everything you used to do with cathode-ray televisions where you needed to get as far away from the screen as possible. These televisions projected electrons against the screen, creating light spots, which were very harsh on the eye, especially if you went close up to the screen. Today's flat screen televisions take their light source from LEDs which do not create any stress on the eye. It's not harmful or even annoying to get close to the screen, although you do need to keep a certain distance back. The closer you are the less brightness you need and so you can compensate for the closeness by lowering the television's brightness. Despite everything, the distance to be respected is determined by an ideal perception of the picture according to the screen's definition. In Full HD, simply multiply the screen's diagonal in centimetres by 2.6 to get the minimum distance where you need to sit. But this isn't down to the exact millimetre. Sitting further away means getting a little less immersion; there's no benefit in sitting closer, as it may even cause less comfort in the long term.
If the television's dimensions are displayed in inches, you need to convert them into centimetres by multiplying by 2.54. A 55-inch diagonal is therefore equivalent to around 140 centimetres. This diagonal in centimetres must be multiplied by 2.6 in Full HD to get the ideal distance of 3.64 metres. In Ultra HD, the coefficient will be just 1.3. In the case of our 140 cm screen, the distance is therefore 1.82 metres minimum. Looking just at Full HD, here are a few correspondences: If the viewer is sitting around two metres away, a 32-inch television will be the best; if they're 2.50 metres away, a 40-inch television will be ideal and 3.50 metres away you'll need a 55-inch television. In Ultra HD, when you're two metres away you can choose a 55-inch screen and at 2.50 metres a 65-inch screen.
