Description
When a source is setup, the system automatically detects and adjusts the image
capture settings at start up and continues to adjust every 60 seconds during
operation. To change the number of seconds between update, enter a value, or
0 to disable the feature, otherwise the default of 60 seconds is set.
When an image is not aligned in the window, use this feature to move an image
up or down on the screen. The values range from 20 (moves the image up) to –
20 (moves the image down).
When an image is not aligned in the window, use this feature to move an image
left or right on the screen. The values range from -999 (moves the image to the
left) to 999 (moves the image to the right).
Specifies phase adjustments for VGA signals. Generally not used unless value is
provided by Epiphan support.
Configurable for DVI and VGA sources only.
Changing the value adjusts the horizontal resolution of the image. Adjust the
value using small increments until the image is sharper. The value ranges from 0-
999 to 999.
Configurable for DVI and VGA sources only.
The Offset and Gain parameters function as contrast control for an image. The
Offset controls the darker parts of the image and the gain controls the bright
parts of the image. Adjust both values to optimize image quality. Adjust the
values using small increments until the image is sharper. If you set Offset to a
high value, set a high value for the gain to balance the two.
