The diagonal indicates the size of the screen. The general recommendation is to place the TV receiver so that the viewing distance of the screen is at least three times the size of the diagonal.
Resolution is also related to this. The larger the diagonal, the more resolution is needed for high-quality display of details. It also depends on the resolution of the program itself, the so-called signal source, with which resolution the program will be displayed.

Do you plan to watch TV at night and play games during the day? Choose a device with higher brightness and contrast. For daytime viewing, a TV with a brightness of at least 500 cd/m2 with the possibility of individual adjustment is suitable. Contrast is a ratio parameter in displaying black and white.

OLED TVs offer the best contrast between black and white. They work on a different principle than LED technology. The principle of organic diodes of OLED panels allows you to independently regulate or turn off the backlight of each pixel. This achieves a blacker black than with other LED panel technologies. It provides the best contrast for day and night program viewing. OLED TV devices are characterized by large viewing angles. Integrated tuners make it possible to receive all basic types of TV broadcasts in most OLED Smart TVs. Terrestrial digital DVB-T, cable DVB-C, and satellite DVB-S broadcasting.
Technologies of QLED televisions, NanoCell, ULED, or QNED mini LED TV devices are an improvement of older LED technology. They are typical of the panel backlighting with LED diodes. They are characterized by improved algorithms and technologies for achieving more perfect color display, advanced motion processing, better brightness, contrast and other parameters. The upscaling function automatically improves the image quality from a lower to a higher resolution for a better viewing experience when watching older programs. Most new TV receivers are equipped with a lot of connectors and ports. The basis is HDMI, USB, LAN connectors, as well as a CI-slot for a satellite decoder.

Due to their properties and parameters, LED panels are suitable for TV sets with smaller diagonals for caravans, cottages, or kitchens. With basic Edge LED backlighting , the LEDs for backlighting are located on the edge of the panel and the light spreads through light-conducting layers. With Direct LED backlighting , the LEDs are distributed over the entire surface of the panel. Direct LED together with the Local Dimming function improves the display of dark scenes in particular. LED TVs reach a standard viewing angle of 170 to 178°.
The EU energy label for televisions, monitors and displays clearly informs about the basic energy parameters of the devices. A significant scale of energy efficiency informs in the range A to G about the class of energy efficiency. The most economical TVs are proud of the A designation. The comparative energy parameter is energy consumption at standard dynamic range (SDR) in kWh/1000 hours and also energy consumption at high dynamic range (HDR) in kWh/1000 hours. Additional information is the size of the diagonal in inches and centimeters, as well as the horizontal and vertical resolution. It includes the exact marking of the device and a QR code. It contains a detailed product information sheet in the product database.
