Hvis en computerskærms elforbrug ved prøvning ligger mindst 15 % (dvs. 15 % eller mere) under Energy Star-specifikationen i alle tre tilstande (tændt tilstand/aktiv tilstand, dvaletilstand/energibesparende tilstand og slukket tilstand/standby), foretages der kun én prøvning.
For the purposes of Energy Star, if a tested computer monitor uses at least 15 % less power (i.e. greater than or equal to 15 %) than the Energy Star specification in all three operating modes (On Mode/Active Power, Sleep Mode/Low Power, and Off Mode/Standby Power), then it only has to be tested once.
