# Council Decision of 13 November 2012 on the signing and conclusion of the Agreement between the Government of the United States of America and the European Union on the coordination of energy-efficiency labelling programmes for office equipment (Text with EEA relevance) (2013/107/EU), Division (8): Set size and luminance as follows:


(a) Initiate the AT01P (Alignment Target 01 Positive Mode) pattern (VESA FPDM Standard 2.0, A112-2F, AT01P) for screen size and use it to set the display to the Partner's recommended image size, which is typically slightly smaller than maximum viewable screen size.
(b) Then, test pattern (VESA FPDM Standard 2.0, A112-2F, SET01K) shall be displayed that provides eight shades of gray from full black (0 volts) to full white (0,7 volts). Input signal levels shall conform to VESA Video Signal Standard (VSIS), Version 1.0, Rev. 2.0, December 2002.
(c) Adjust (where feasible) the display brightness control downward from its maximum until the lowest black bar luminance level is just slightly visible (VESA FPDM Standard 2.0, Section 301-3K).
(d) Display a test pattern (VESA FPDM Standard 2.0, A112-2H, L80) that provides a full white (0,7 volts) box that occupies 80 % of the image.
(e) Adjust the contrast control until the white area of the screen is set at the following luminance: 100 cd/m2
(f) measured according to VESA FPDM Standard 2.0, Section 302-1. (If the display's maximum luminance is less than the prescribed luminance, above, the technician shall use the maximum luminance and report the value to EPA or the European Commission, as applicable, with other required testing documentation. Similarly, if the display's minimum luminance is greater than the prescribed luminance, the technician shall use the minimum luminance and report the value to EPA or the European Commission, as applicable.)
(g) The luminance value shall be reported to EPA or the European Commission, as applicable, with other required testing documentation.
