Hi,
I use the AW 17R4 fn+F8 combo and select ‘second screen only’ option to turn off the laptop screen and switch over to external screen. The use of Tobii eye tracking itself isn’t really useful of course when looking at an external monitor when the eye tracking camera is a bit off to the side of the external screen. I am mostly looking that Windows Hello keeps working.
Perhaps my use case is really rare. I solved the issue by no longer requiring login to the computer, but would prefer windows hello to continue working.
Thanks
