Cytat:When the first EU energy regulations were introduced, many TV sets were set into a ‘vivid’ mode when they came out of the box. TV makers wanted retailers to use that mode to sell their sets. Although those who care about good picture quality understand that careful control of the set brightness is needed, buyers often choose the brightest or more colorful sets in-store. As many consumers don’t adjust the picture settings when they get the set home, the default Vivid mode uses more power than was needed. The EU, therefore, adopted the policy of changing the regulations so that the energy label rating was based on the ‘out of box’ mode.

That gives set makers an option – to supply the TV with very low brightness settings in an out-of-box mode so that the power used meets the regulation. It seems that Sony’s 8K TVs are already adopting this approach.

Swoją drogą ostatnio sprawdzałem swój TV watomierzem i zaskoczyło mnie, że w trybie DV / HDR w normalnie wyglądającej, wcale nie ciemnej scenie skakało między zaledwie 60 a 80W. Dopiero dość intensywne sceny powodowały skoki do 120-150W, natomiast do 250W dobiłem na chwilę w jednym z tych przesadzonych dem na YouTube przeznaczonych do puszczania w sklepach.
