Video output port resolution
The video output port's resolution (also known as frame size or display mode) defines the number of pixels displayed horizontally and vertically. For example, the resolution 1920×1080 (1080p) produces an image that is 1920 pixels wide by 1080 pixels tall.
Pearl-2 always assumes that the output display uses square pixels.
The aspect ratio (eg. 4:3 or 16:9) describes the proportional relationship between the video output's pixel width and height. The resolution 1920×1080 (1080p), for example, is quite a bit wider than it is tall. The ratio of its width to height is 16 to 9, which has an aspect ratio that is 16:9.
By default, you can choose from the following output resolutions for your video output ports, but you can also change settings to allow a variety of other resolutions through.
