Seems others have resorted to cheating software in 'test mode' to meet efficiency standards, in this case for energy usage.......


TVs: the next testing scandal? | The Economist

The TV issue is probably not one for this forum but TV's, on average, are getting bigger, brighter and higher resolution. To accomplish these goals and still get the energy star rating they typically use set up tricks: if the luminance value of the overall screen is at maximum then the brightness is turned down to save energy. There are other subtle electronic tricks that are usually defeated once the TV is set up correctly in the home.
This problem will get worse with the higher demands of UHD, HDR and OLEDS.

BTW I worked with a 42 inch TV that drew 80 amps. It conformed to a proposed Dolby HDR standard of over a 1000 NITS of brightness. Yes the contrast ratio was impressive but I could not watch it for long and if I had to then I would wear sunglasses. The bottom line is that all the manufacturers want you to buy new TV's but the newer systems can be power hungry and the feds are watching.
