As br1 pointed out - scaling DPI is what Windows does and OSX doesn't - not resolution as you appear to have tested with. No LCD is going to look good at non-native resolution - what you want to do is use the native res of the display and up the DPI in Windows to 120%. Works unquestionably well for most apps if you use XP Style scaling.
That's just making the text bigger, thanks but I already know how to do this.
The other guys were talking about "scaling the DPI". Are they really the same thing? In which case, why on earth wouldn't they just say "make the text bigger"?
