the device has horizontally arranged components in the order blue-green-red from left to right.
the device has horizontally arranged components in the order red-green-blue from left to right.
the device displays colors without geometrically-separated subpixel components, or the positioning or colors of the components do not match any of the values in the enumeration.
the layout of subpixel components for the device is unknown.
the device has vertically arranged components in the order blue-green-red from top to bottom.
the device has vertically arranged components in the order red-green-blue from top to bottom.
Some output devices (such as LCD panels) display colors by making each pixel consist of smaller "subpixels" that each have a particular color. By using knowledge of the layout of this subpixel components, it is possible to create image content with higher resolution than the pixel grid.
