# Screen-share Parameters
Screen-share parameters are separated by where they are applied:
* **Source side** options belong on publisher links, such as [`&push`](/advanced-settings/setup-parameters/push.md), guest invite links, or room participants who will share a screen.
* **Viewer side** options belong on receive links, such as [`&view`](/advanced-settings/mixer-scene-parameters/view.md) or [`&scene`](/advanced-settings/mixer-scene-parameters/scene.md), and control how incoming screen shares are requested or displayed.
Use [`&screensharehide`](/advanced-settings/screen-share-parameters/and-screensharehide.md) when the screen-sharing publisher should not see their own local screen-share preview. Use [`&noscreenshare`](/advanced-settings/screen-share-parameters/and-noscreenshare.md) when a viewer or scene link should not load incoming screen shares.
