Does the zoom sdk have a features or settings that prevents the screen saver when attending a webinar? We are using the zoom sdk embedded on our website, mainly on the chrome browser on windows 10.

We would like to prevent the screen saver from running during the webinar i… ---

in a **browser** the trick with the **html5 video** is - as far as i know - the only way to block the screensaver in an app of course it looks completely different, e.g. Windows C++: > **[SetThreadExecutionState function (winbase.h) - Win32 apps](https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-setthreadexecutionstate)** > > Enables an application to inform the system that it is in use, thereby preventing the system from entering sleep or turning off the display while the application is running. ---

Hey @shoaib We do have an option named `stayAwake` in the `init` method, but it’s only available in Chrome or Chromium-like browser. > **[WakeLock - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/WakeLock)** > > The WakeLock interface of the Screen Wake Lock API prevents device screens from dimming or locking when an application needs to keep running.

Hi Vic, ``` I tried this code to prevent the screen saver to kick in when the video call is going on. I couldn't see any error in the console. But, the screen saver kicks in. ``` client.init(‘en-US’, ‘Global’,{stayAwake: true}) Zoom video SDK version: 1.5.1 Browser: Google Chrome Version 107.0.5304.107 (Official Build) (64-bit) OS: Windows 10 Pro System Type x64-based PC Please help me to resolve this issue.

Hey @kvr We found an issue with `stayAwake` in Video SDK Web and it will be fixed in the next release. For now, WakeLock is still a good solution.
