I’m a 3 monitor person as well. 34" ultrawide as my main with two 24" widescreens side-to-side immediately above it. I use it for work and personal use.
Ultrawide has my main programs for work: internet browsers and job specific programs get about 60% of the real estate on the left, while pdf’s, and other less essential programs go to the right 40% of the screen.
The top left monitor gets Teams, Excel docs, or auxiliary browsers.
Top right gets email and media (YouTube, Spotify, etc) or any overfill if I’m dealing with a particularly cluttered job.
For personal, ultrawide is obviously used for games, movies, etc, while top left has task manager, MSI Afterburner, and Throttlestop (I run a laptop). And the top right has Discord.
There was a video he did on a startup taxi service using self driving cars. Basically the entire thing was an advertisement for that company.
Then another Youtuber, Tom Nicholas, released a video about that a few months later and how it’s an issue. I’ll have to watch it again as I don’t remember what he specifically talks about.
