How much does a 4K Smart TV really consume per year? Real-bill examples
How to read the energy label of a 4K Smart TV, calculate annual consumption and use Eco modes. Practical examples with the Sinudyne range.

The consumption of a modern 4K Smart TV is shown on the energy label in kWh/1000h: with a few hours a day of use, the annual cost is often lower than many imagine, especially with efficient LED panels. Sinudyne TVs combine 4K with energy-saving features to balance quality and consumption.
How to read a TV energy label
On the label you'll find:
- energy class (letter);
- consumption in kWh/1000h in SDR and often HDR.
Many guides show examples of annual cost calculation, starting from this info and the real number of hours you keep the TV on.
Simplified example of annual consumption
If you watch TV 4 hours a day:
- 4 hours × 365 days ≈ 1460 hours/year;
- if the TV consumes, for example, 90 kWh/1000h, annual use is around 131 kWh.
With updated energy costs, guides highlight that the impact of a modern 4K is often lower than other major appliances.
Energy-saving features on Sinudyne TVs
Sinudyne Smart TVs integrate features like:
- Eco mode and automatic brightness reduction;
- sensors or settings to adapt light to the scenario;
- automatic shutdown after a period of inactivity.
These options let you maintain good image quality while reducing unnecessary consumption.
