I occasionally sit in the garden, under a parasol, and am in very long and boring Teams meetings. I did a web search on how to see the screen better and found a tip
Working Outside on Your MacBook Pro? Invert Your Screen Colors!
That was useful, you can really see the screen better.
What does Invert Your Screen Colors do exactly? How does it work? Is it harmful to the eyes? I'm looking for some more background info on this feature. Does it put more strain on the batteries? Are there any other tips for participating in meetings outside in the garden with a Macbook Pro and never-ending Teams calls?
