blurring background

Hi cleon_germany ,

If you are using the same version of the Teams desktop app on Win10 and it's not available on that other laptop there is a good chance the background blur just isn't supported on that device yet.  I believe there are video card spec's that are required and older video cards might not be supported yet, but they are working on adding support for more.

"Not all devices support background blur yet, but we’re working on it. To find out if it’s available on your device, just try the method described above. Click More options in a meeting. If Blur my background appears in the menu, then you're in business!"
