Bottom monitor touches table and is not at eye level when two 27" monitors are stacked. The top monitor is located at the top of the stand. The LG 5k2k 34" Ultrawide is the same height as a 27" monitor and the Acer Predator X27. The X27 was needed on par with LG above it. The armrest is not long enough to stack two 27" monitors in an ergonomic configuration without the bottom of the monitor touching the table. Choose a higher stand.
