I have a largely jerryrigged desk - its a particleboard table top that's sitting on a pair of metal A frame trestle legs. I recently got a 27 inch monitor and the weight of it is causing the desk to sag. Its an inch thick particleboard that used to have a pair of I frame and a board across it.
I don't have a wood shop or a machine shop so reinforcing the desk is unlikely. How would I keep this from happening in future? Would adding a single table leg be enough or should I add another trestle help? Would having a even wider base for the monitor help spread the load?
