The prefix (SET TOP BOX) for receiving digital TV is sometimes provided with a choice of image format - 1080i or 1080p. The article gives the answer to the question "which option to choose - 1080i, 1080p, 720i or 720p, or 576i".

So that the image does not lose as when output on the screen of TV, the “input” resolution and the deposit format, (unfortunate “i” or progressive ”p” and the proportions of the picture must coincide with the “output” resolution and proportions of the TV matrix.

To determine the resolution and the type of scan, you can use the "Info" button on the console console; You need to click the "Info" button twice to see the advanced information about the television stream.

But the parameters are not required for each channel. There is a simple rule:

1. A video is transmitted by a cable or on the air in a slightly deployed (I). Resolution for DVB-T2 usually SD (576i). Full HD channels - 1080i.
2. via the Internet or with a PC - a video in a progressive (p) deployment. Video resolution can be any from SD (p) to 8k (p).

Thus, for ether or cable TV (not IP TV), you need to choose a slightly (I) deployment.

Что касается разрешения, то если в эфире трансляция ТВ идёт в формате стандартной чёткости 768 x576i (PAL), лучшее использовать ТВ не Full HD разрешения 1920x1080, а обычного HD 768x576. Тогда вывод картинки будет происходить пиксель в пиксель. На экранах более высокого разрешения, чем у источника (Full HD, 4K, 8K) изображение формата SD будет казаться размытым и нечётким, несмотря на интерполяцию.

Naturally, the proportions of the channel and the TV screen must coincide. Most Russian television channels moved from an outdated 4: 3 to the image format 16: 9.

About the transformation of old models of monitors in TV

The old monitors are very cheap (from 300 rubles), but have a 4: 3 matrix format, which is not suitable for the output of modern TV format of 16: 9 from the prefix TV. The HDMI converter in VGA or HDMI in DVI is quite expensive - from 1800 to 3000 rubles. Active (with a built-in amplifier) computer speakers and wires HDMI-HDMI (about 1,500 rubles) and VGA-VGA (500 rubles), a monitor power supply (150 rubles). In my opinion, the transformation of an old computer monitor in TV makes little sense. Moreover, the color reproduction of cheap TFT monitors is much different for the worse from the TV IPS and PVA matrices. The HD TV, in addition, has a diagonal of 32-50 ", while the table monitors-17-19". With a lack of money, it is better to look towards HD TV (they cost about 10,000 rubles) on Android.
