"Full resolution retina display" with Win7 and Macbook 12" not usable

Hi

On the Macbook 12" in OS X the default display resolution is 1280x800 (native resolution 2304x1440).

I created a Windows 7 x64 VM in Fusion 7.1.2 (VMware Tools installed) and in the VM's Display Preferences I checked "Use full resolution for Retina display".

In Windows VMware Tools configured a resolution 2560x1600 and set text size to 150%.

With the Fusion retina display setting the Windows VM requires binoculars to use

I've had to disable "Use full resolution for Retina display" to be able to work in Windows.

I guess my question is what is the point of the retina display option for Windows VMs and is there something I'm missing in my configuration that would

allow me to ditch the binoculars?

Thanks.
