Brightness2 Test

  • Article

Contains: Code: \windowstest\graphics\base\tests\brightness2 Tests: brightness2.dll Tests run on internal monitor. DevX::BaseVideo::TestSmoothBrightenessControl Test uses private escape to verify: - smooth brighness is supported (Skipped if not). - number of brightness levels supported by the driver is more or equal of 101. - smoth brighness ON doesn't afffect Set/Get Brightness DDI functionality. - there is a trasition period ( 0.1< t < 0.5) when brighness changed from MIN to MAX and from MAX to MIN. DevX::BaseVideo::TestAdaptiveBrightnessControl Test uses private escape to verify (with brightness level set to MAX): - adaptive brighness is supported (Skipped if not). - verifies that user brightness seeting (Usersettings) is not affected by different DxgbacklightOptimization levels - verifies that actual brightness (ActualBrightness) is affected by different DxgbacklightOptimization levels as follows: DxgBacklightOptimizationDynamic: Actual <= Actual for otimization OFF. Gamma >= Gamma for optimization OFF. DxgBacklightOptimizationDimmed: Actual <= 0.5* Actual for otimization OFF. Gamma >= Gamma for optimization OFF.
