>>105591084 (OP)2 feels uneven. One in the middle you look at and one off to the side. Or, having a bezel split in the middle and two screens off to the side.
I prefer 1 or 3. Anything more than that gets weird.
Ideally though, I prefer the 3 + 1 set up, where it's three monitors, plus 1 TV/Monitor above those three, but is connected to a different device.
