# \&sharper

Viewer-Side Option! ([`&scene`](https://docs.vdo.ninja/advanced-settings/mixer-scene-parameters/scene), [`&room`](https://docs.vdo.ninja/advanced-settings/setup-parameters/room), [`&view`](https://docs.vdo.ninja/advanced-settings/mixer-scene-parameters/view), [`&solo`](https://docs.vdo.ninja/advanced-settings/mixer-scene-parameters/and-solo))

## Aliases

* `&sharpen`
* [`&dpi=2`](https://docs.vdo.ninja/advanced-settings/video-parameters/dpi)

## Details

`&sharper` is now an alias of [`&dpi=2`](https://docs.vdo.ninja/advanced-settings/video-parameters/dpi), which should 'up to' double the amount of playback video resolution, if the dynamic resolution optimization is enabled at least, in certain cases. This is a lot like [`&scale=100`](https://docs.vdo.ninja/advanced-settings/video-parameters/scale), but perhaps *slightly* more efficient in some cases. This is mainly for when you intend to have a large screen-share in a scene, where you don't want the tiny guest videos to be a 100% scale, but 50% scale is fine (up from 25% scale). [`&dpi`](https://docs.vdo.ninja/advanced-settings/video-parameters/dpi) already exists on production, but by adding these aliases, I hope it's more discoverable.

As an alternative to `&sharper`, I've also added [`&sharperscreen`](https://docs.vdo.ninja/advanced-settings/screen-share-parameters/and-sharperscreen), which sets [`&scale=100`](https://docs.vdo.ninja/advanced-settings/video-parameters/scale), but *only* for screen-shares (virtual cameras not included). This is probably even more efficient than [`&scale=100`](https://docs.vdo.ninja/advanced-settings/video-parameters/scale) or `&sharper`, and it's designed for when screen-sharing a lot of text. Text looks a bit soft when streaming video at 1:1 pixel resolution.

It's recommended to only use these parameters within the context of a scene link, and not on guest links, due to the higher CPU / bandwidth it may use.
