The stand is made for and tested up to 24 inch monitors. These are direct bolt on as long as your VESA bolt pattern is 75mm x 75mm, 100mm x 100mm, or 200mm x 100mm. If you want to use larger monitors, it could be done with some modifications on the user’s end. Just have some 2mm sheets of metal cut to size, a drill and some nuts and bolts. You should be able to create your own mounting plates to be bolted to the existing mounting plates and offset of course to give enough room for the widths of your monitors. That being said, 24 inch monitors are still the highest quality (large) monitors available at decent prices, and three of them are incredible. I use three 22″ monitors and have over a 4 foot viewing span horizontally and it’s plenty for me.
