Explanation:

BThe Effectiveness of the Device is Noticeable at First Sight.
Energy efficiency class is a standard classification that is used all over Europe and which is understandable at first sight. Products can be efficiently compared according to classes, starting from A+ (the most energy efficient class), and ending with F (the most energy-intensive class). The classification of energy efficiency is based on annual energy consumption which is being calculated on the basis of several different parameters.

274Annual Energy Consumption.
Annual energy consumption in the switched-on state expressed using a measurement unit kW/h per year.

165/65
Screen Diagonal.
Diagonal of the visible part of the screen expressed in centimeters and inches.

187Power consumption.
Power consumption in switched-on state expressed in W.

Switched-off state.
The given mark is displayed on TVs that have a clearly visible switch that when being set in switched-off mode switches the TV into a mode with power consumption no more than 0,01 W.

Switched-off state.
The given mark is displayed on TVs that doestn't have a clearly visible switch that when being set in switched-off mode switches the TV into a mode with power consumption no more than 0,01 W.
