I bought a screenset for routers and the guy told me how to do it. You start Mach 3 a normal and then enlarge the outside window that Mach is in.
The Mach display will stay the same but the window is larger. Go into config and the general config and down the bottom there is a small check box for Auto screen enlarge put a check in it. Then exit Mach 3 and then restart it, the display will now fill the outer window frame
