The following are valid parameters that can be configured under the display section:
Parameter | Description | Type | Possible Value(s) |
---|---|---|---|
background | The background color of the display. Use RGB color code (HEX value) to identify the color. (e.g., blue = 0xff) | unsigned long integer (hex) |
|
cbabc | Content-based automatic brightness control; specifies the content type of the display | string |
|
cursor | The visibility of the cursor on the display | string |
|
formats | The pixel format(s) supported by the display. This parameter can be configured with multiple values. | string |
|
gamma | The gamma value of the WFD driver. The range for this gamma value is specific to the driver. | unsigned long integer | 0..255 |
idle-timeout | The amount of time (in seconds) after which the display will enter an idle state. | string or unsigned long integer |
|
mirroring | The mirror types | string |
|
priority | The priority of the update thread (i.e., the thread that renders the framebuffer(s)). | integer | Default: 15 |
rotation | The clockwise rotation of a display. Display rotation is absolute. | long integer |
|
rotation-mode | Your preference of display rotation mode. If the mode of rotation specified isn`t supported by your display controller, the default is to use blitter rotation. | string |
|
splash | Indicates whether or not to post framebuffer on start-up. This parameter is considered only if the WFD driver supports it. | integer |
|
stack-size | The stack size (in units of 1024 bytes) that Screen is to use for its threads. stack-size must be configured appropriately for blitters/compositors that are using Mesa (e.g, gles2blt). The default stack size of 4 * 1024 bytes is insufficient for these types of blitters/compositors. | integer | 2048 |
touch-adjustments | The x and y adjustments to be added to all touch events. This configuration must be in the form: x-adjustment,y-adjustment | unsigned long integer | |
video-mode | The initial resolution and refresh rate for the display port. This configuration must be one that is reported by the WFD driver. If you set this to values that aren't supported, then the resolution and refresh rate will default to the first mode specified by the driver. The resolution and refresh rate must be in the form of: widthxheight @[i]refresh For example, video-mode = 1280x720@60. If i is indicated, then interlacing is set. | unsigned long integer | |
protection-enable | Content protection for the window(s) on the display. Typcially this is set only if the application is interested in HDCP (High-Bandwidth Digital Content Protection). | string |
