I have dual 4k monitors. Normally have a primary task on the first screen, and a secondary/tertiary task on the second. I'd get a 3rd monitor, but my desk is already huge and can't fit another.

I had great success getting 3 monitor vesa mounts and then just bolting them to the desk. The ones I got were like $30, made of strong steel, and even came with a clamp attachment in case you didnt want to drill holes to bolt it down.
