For instance, screen mirroring apps might only support 1080p or even lower resolutions if the network conditions are not optimal. Always check your devices’ specifications to optimize the settings for the best possible resolution.
Are there any security concerns I should be aware of while sharing my screen?
Yes, there are potential security concerns when sharing your screen, especially with wireless connections. Unsecured networks can expose your screen-sharing session to unwanted viewers. It’s crucial to use secure networks and consider using a VPN for added protection, particularly when dealing with sensitive information.
Additionally, ensure that you only share your screen in trusted environments. Turn off notifications that could pop up and reveal personal information, and be mindful of what’s on your desktop or applications that are accessible while sharing. Taking these precautions helps maintain your privacy and keeps sensitive information secure during presentations or meetings.
