Type: Automated test

Overview

The Graphics - Additional Qualifications – Nominal Range Color (manual) test verifies that a display adapter is applying the correct nominal range setting for color when playing video.

Details

This is tested by using a grayscale pattern that allows verification of nominal range settings.

This test verifies the following requirements:

GRAPHICS-0008: Display adapter or chipset meets color space requirements

Success: This test succeeds if the device driver and device complete the following:

  • The test prompts the tester to switch the display adapter to the default nominal color range.

  • The test plays back a gray level test pattern file.

  • The test takes a screenshot and verifies that the brightness values in the screenshot are 16 and 235 for pixels with values 16 and 235 in the recording.

  • The test prompts the tester if the range can be changed to full.

    • If the tester answers yes, it plays back the same file, takes a screenshot, and checks that the brightness values are 0 and 255 for pixels with 16 and 235 in the recording.
    • If the range cannot be changed, this test is omitted.

Failure: This test fails if:

  • The brightness values of pixels in the screenshot are not as expected.
  • Any of the steps above fail.
