Background the key image portion and high luminance colors for the logo 49
Becomes not letting the main window show through to use this feature it is 49
For certain displays the screen may flicker once for about a second after activating or changing the luma keying setting 49
Letting the main window image show the higher the luminance the less transparent it 49
Location and then turn luma keying on the pip image will show without its 49
Recommended to set the pip image as follows use low luminance colors for the 49
The lower the luminance in the pip window the more transparent it becomes thus 49
The luma keying feature 49
The luma keying feature lets you display the pip window the key image as semi 49
To apply the luma keying feature first set the pip window to the desired size and 49
Transparent background 49
Transparent over the main window this feature can be used to have the pip 49
We recommend that you activate luma keying after completing the setup 49
When the luma keying feature is on any change in the setup either by the user or by resetting due to a setup change may cause the screen to flicker once the luma keying will recover automatically after resetting 49
