# 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 Nexus always assume 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 in 4:3 and 16:9 aspect ratios for your video output ports, but you can also change settings to allow a variety of other resolutions through.

4:3 resolutions

| **1024×768** | **1280×960** | **1400×1050** |
| --- | --- | --- |

16:9 resolutions

| **1280×720** | **1360×768** | **1920×1080** |
