I tried that but. my 1080p monitor is already at 100% and it cant go any lower.
Oh right, well you can't scale less than 100%. You 1080p monitor is running things 1-1, which is as small as they can go. Windows prevent you from sub 96dpi scaling (100%), because it causes issues with text rendering. Apparently there are hacks floating around which involve a registry tweak, but you may well have issues getting it set to one display only, and there are then issues stemming from the hack. Apparently it can cause a range of other issues.
Maybe someone else comes along with a good suggestion, but from what I understand, Windows can't do what you want natively. And any hacks/fixes introduce more problems then they solve.
