A:Answer Dave, you can get two of them and mount all 4 monitors, two on each stand, over top of each other. However the lower monitors will only be a couple inches off the desk. I don’t think there is enough clearance at the highest point to put one stand with both monitors side-by-side over top of two monitors on regular stands on your desk unless the regular stands will adjust really low.
That said, if you’re close enough to a Best Buy store, returns are super easy if it doesn’t work out.
