Resolution guide
| Resolution | Name | Typical use |
|---|---|---|
| 640 × 480 | VGA | Older laptops |
| 1280 × 720 | HD (720p) | Most laptop webcams |
| 1920 × 1080 | Full HD (1080p) | Good external webcams |
| 3840 × 2160 | 4K | Premium webcams and cameras |
The test asks for up to 1080p, so 4K cameras show as 1080p here; the maximum resolution line shows what the camera supports.
Tips for a better picture
- Light your face from the front, for example with a window or lamp behind the screen.
- Avoid bright windows behind you, which turn you into a silhouette.
- Raise the camera to eye level.
- Clean the lens: laptop cameras collect fingerprints.
