Then I switched to a 2x2 configuration (effectively 8K resolution). All displays are identical 27” 4k. They are each angled slightly toward the center.
For the 2x2 config I bought two different monitor stands from Planar because they're the BEST! But their big stand is too tall (I just use the arms. Beware the big stand's vesa mounts block ports on my LG monitors) and their small stand is too small (good height and good vesa mounts, but the arms are too short for 27" displays). I used parts from each 2x2 stand to build one perfect 2x2 stand.
I'll never go back.
