The number one problem i ve found over the time i ve sold monitor arms is how they attach to the monitor.
Mount monitor to wall no screws.
Vesa compliance is like a foreign language if you re new to the category.
Monitor requires vesa mount.
Wali vesa mount bracket adapter monitor arm mounting kit for screen 13 to 27 inch vesa 75mm and 100mm uvvep 4 5 out of 5 stars 1 909.
Not all monitors have them.
If your monitor model number is sa240y this does not have a vesa wall mount.
Therefore cannot be mounted to a monitor stand or wall mount for ergonomic setups.
Having a vesa compliant monitor means that it comes with standard mounting holes on the back of the monitor.
No you need standard vesa mount holes in your monitor in order to hang it on the wall or on a stand.
If your product does not have the screw holes indicated by red squares in the image below it may not support vesa mounting.
Some models require removal of the monitor stand to access the mounting holes.
Today a large portion of the well designed monitors lack vesa mounting compatibility.
