Parallels version 9.0.24217 with Windows 8.1 build 9600 I have been running Parallels for a few years, previously on a MBA with Windows 7 with Office 2010 and since a few months on a 15" rMBP. Since the scaling of Windows 7 is terrible (1920x1200 full screen on the retina display is quite blurred) I have ventured out to try Windows 8.1 with Office 2013 and to a large degree have been pleasantly surprised. One thing that is seriously bugging me is that Parallels refuses to run at native resolution in any other OS X display mode than Best for Retina. I personally think that Best for Retina is pretty useless since you end up with a lot less screen real estate. When I run at the More Space option (effectively 1920x1200 on OS X), Parallels gives Windows in full screen mode the resolution 3840x2400. What now happens is that Windows starts to render at this resolution (which it can now perfectly well) only for OS X to scale it down to 2880x1800. And voila the text starts looking blurred again. Not as much as with Windows 7, but still noticeable. Only when I switch OS X to Best for Retina Parallels will give Windows the native 2880x1800 resolution and text looks perfectly sharp. Does anyone know of a way to force the native resolution in Parallels regardless of the OS X display setting? @Parallels, if you're reading, a configuration setting for this would be very welcome!!!
