Stacked Monitors vs Side by Side?

From a chat in Discord, the topic of stacked monitors came up. I’ve used stacked monitors in the past and here’s my experience.

  • having stacked screens is nice as your neck stays neutral in left/right position. I deal with shoulder pain when i work with dual displays.
  • however, I have two 27" screens, and the top was a little too high and the bottom a little too low to comfortably use. I’d be too far out of neutral up or down depending on which screen I was using primarily
  • as a result I moved on from this setup.

I think if you were able to use smaller displays (24" or under) this might work well. What I’ve been doing instead is using one monitor centered in front of me as my primary display, and the other to the left in vertical orientation. This display is for reference only (tasks/chat/calendar).

Is anyone else using stacked monitors? What’s been your experience?
