Swapping a monitor off the arm means unboltting four screws, wrestling the panel, then doing it all in reverse. The Brateck XMA-03 quick release plate kills that. You bolt it to the back of your screen once, and after that attaching or removing the monitor is a click-and-go motion. Individual height adjustment on the VESA plate means both screens sit level without shims. Steel build, matte black powder coat. Fits VESA 75x75 and 100x100 patterns, panels from 17" to 27", up to 8kg. One screen per adapter. Not for curved panels. If you're already running a standard arm and just want the swap to stop being a project, this is the fix
