Division (8) Set size and luminance as follows:

Original text. Later amendments are not shown.

  1. (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.

  2. (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)f1. Input signal levels shall conform to VESA Video Signal Standard (VSIS), Version 1.0, Rev. 2.0, December 2002.

  3. (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).

  4. (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.

  5. (e)

    Adjust the contrast control until the white area of the screen is set at the following luminance: 100 cd/m2

  6. (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.)

  7. (g)

    The luminance value shall be reported to EPA or the European Commission, as applicable, with other required testing documentation.

Corresponding voltage values for digital only interface displays that correspond to the brightness of the image (0 to 0,7 volts) are: 0 volts (black) = a setting of 0, 0,1 volts (darkest shade of gray analog) = 36 digital gray, 0,7 volts (full white analog) = 255 digital gray; please note that future digital interface specifications may widen this range, but in all cases, 0 volts shall correspond to black and the maximum value shall correspond to white, with 0,1 volts corresponding to one-seventh of the maximum value.
