... I switch it up depending on the game.

Left screen is for the chord (fucken noons won't get off it), and browser. Right is for gaming because its actually center of the desk.

Right screen just because it happens to be closer to me on my corner desk arrangement.

Nowadays I run a dual 4k monitor setup with the left centered in my FoV and the right one alternating between portrait and landscape. My laptop usually sits under the primary or to the bottom left. I connect over thunderbolt so I can easily swap out my work and personal laptop on the dock. Effectively I get 3 screens: my main focus, my distraction, and my comms on the built in display. If I'm gaming on the desktop I toggle the left monitor to another input. I used to have more screens but things are a lot more ergonomic now.

I do feel like I could switch to right monitor dominant, bit I think it would not be ideal considering sloppily moving the mouse to the top left on the primary would cause the mouse to jump to the secondary screen whereas on a left monitor dominant layout it would hit the border. You could offset the displays slightly to catch the mouse, but it's not worth it.

Game on the right, but I have no choice over it, I might have chosen left if my wall mounted monitor wasn't on the left.

But, the positive is that it takes up no desk space because in the left, it's just air.

Right monitor is 16:9 and VRR, left is a 16:10 monitor my work gave me during covid. So games go on the right.
