Screen resolution - its size in pixels horizontally and vertically. Other things being equal, a higher resolution provides better image quality, but such a screen costs more and requires relevant content.
The set of resolutions found in modern TVs is quite extensive, but they can be roughly divided into several groups:
HD,
Full HD,
Ultra HD 4K, Ultra HD 5K and
Ultra HD 8K. Here are the main features of each option:
— HD. Screens designed for HD 720p. The standard frame size in such a video is 1280x720, however, for a number of reasons, most HD TVs have somewhat larger sizes — 1366x768. In addition, this category usually includes models with resolutions from 1280x768 to 1680x1050, as well as 1024x768 screens. In general, HD 720p resolutions are mostly found on low-cost TVs with relatively small screens.
— Full HD. TVs designed for Full HD 1080p video, with a frame size of 1920x1080. Most models from this category have exactly this screen resolution — 1920x1080; other options are noticeably less common — in particular, 1920x1200 and 2560x1080. In general, Full HD screens provide good detail at a relatively low cost, making them extremely popular in mid-range models and inexpensive large-format TVs.
— Ultra HD 4K. This format provides different options in resolutions, however, for TVs, the actual stan
...dard is 3840x2160, other options are almost never found. In general, this is a fairly high resolution, which is typical mainly for premium models; a common feature of such models is the large size — from 40" and more.
— Ultra HD 5K. The Ultra HD image format is more advanced than 4K, but it is extremely rare in TVs — these are mainly ultra-wide models with a resolution of 5120x2160.
— Ultra HD 8K. A standard that assumes a size of about 8K pixels horizontally; one of the options for this resolution, found in TVs — 7680x4320. Thus, UHD 8K is twice the size of 4K on each side and four times the total number of pixels, resulting in extremely sharp and detailed images. On the other hand, such screens are very expensive, despite the fact that nowadays even 4K is already considered a very advanced standard. Plus, there are not many video devices and content that meet this standard. Therefore, 8K TVs are still extremely rare, they include mostly high-end flagship models with a size of at least 65".The electrical power normally consumed by the TV. This parameter strongly depends on the screen size and sound power (see above), however, it can be determined by other parameters — primarily additional features and technologies implemented in the design. It is worth noting that most modern LCD TVs are quite economical, and most often this parameter does not play a significant role — in most cases, power consumption is about several tens of watts. And even large models with a diagonal of 70 – 90" consume about 200 – 300 W — this can be compared with the system unit of a low-power desktop PC.
