Upscaling

TV support for Upscaling function. This feature is only available on models with 4K and 8K resolution screens.

Upscaling to 4K allows you to increase the resolution of the original “picture” to 4K (3840x2160), if it was initially lower - for example, viewing a movie in 4K that was originally recorded in Full HD (1920x1080). In this case, we are not just talking about “stretching” the image to fill the entire screen (all TVs are capable of doing this), but about special processing, thanks to which the actual video resolution is increased. Of course, such video will still be inferior to content originally recorded in 4K; however, upscaling provides a noticeable improvement in quality compared to the raw signal.

Upscaling to 8K works on the same principle, only relevant for 8K TVs.

Brightness / contrast enhancement

TV support for one or another brightness / contrast enhancement technology.

Usually, in this case, software image processing is implied, in such a way as to improve brightness and/or contrast (if necessary). Specific processing methods may be different — in particular, in some cases we are actually talking about turning standard content into HDR (see above), and some manufacturers do not specify technical details at all. The effectiveness of different technologies can also be different, and besides, it is highly dependent on the specific content: in some cases, the improvement will be obvious, in others it may be almost imperceptible. Also note that this feature is not always useful, so in most models it is turned off.

Power consumption

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.

Energy efficiency class

The energy efficiency class characterizes how efficiently the TV consumes electricity. Initially, the classes were denoted by simple Latin letters — A (the most efficient), B, C. However, later improved classes “A+ ”, “A++”, etc. appeared (the more "pluses", the more efficient the device).

The energy class will generally affect the price accordingly, but this difference will eventually pay off with lower electricity bills.
