This view - in the image above - is what we refer to as the tunneling effect.

What Causes The Tunneling Effect?

The tunneling effect occurs when the screen or window selected to be shared is the live room itself.

For example, let's say you are sharing your entire screen and you open the live room. You and all of your participants will see the tunneling effect.

There isn't anything particularly harmful about this view. In some cases it can cause your computer to work harder than it should. Mainly the tunneling effect is distracting and best to be avoided.

How To Avoid The Tunneling Effect

  • Utilize two monitors - When sharing your entire screen, the best way to avoid the tunneling effect is to use two monitors/screens. Before you start sharing, you can select the screen the live room is not on and share that. This is super convenient because you can see the live room - your participants, chat, raised hands, screen you are sharing as others see it - while navigating the screen you are sharing on the other monitor.
  • Share specific applications* - You can choose to share a specific application when sharing your screen with the Newrow Screen Share Web Extension. When you select the Desktop Share option in the Tools menu, you will see a Share Your Screen pop-up. Select the Application Window option and choose a specific application** to share only that.
