What is resolution?

In simple terms, resolution refers to the quality of an image or video. When we’re talking about an image or video on a screen, the resolution is measured by the number of pixels, horizontally and vertically.

You can set your pixels to just about anything you want, but these are the most common formats:

Format                                                                                Resolution (px)

Standard Definition (SD) / 4:3 aspect ratio                            640 × 480

Standard Definition (SD) / 16:9 aspect ratio                          640 × 360

720p HD / 16:9 aspect ratio                                                    1280 × 720

1080p HD / 16:9 aspect ratio                                                1920 × 1080

2K / 16:9 aspect ratio                                                             2560 × 1440
